A consultant charges 500 to 2,000 dollars a month for SEO, and an agency charges more again for a full campaign. An AI SEO tool charges nothing to try and 29 dollars a month to track, and that gap is the reason most small sites start with a tool. The gap also hides the real question, which is not whether a tool is cheaper, because it is, but what the subscription actually buys. That question is the heart of ai seo tool pricing, and it is the number this guide works out for every tool.
A tool that sells tracking for 29 dollars a month and a tool that charges 139 dollars a month are not selling the same thing. The first sells a keyword list and a rank check. The second sells a full suite with audits, backlinks, content tools and AI visibility reports. A site that tracks 50 keywords pays less with the cheap plan, and a site that tracks 500 keywords across five sites pays less with the plan that counts projects, not keywords. The billing model decides the bill more than the headline price does.
The third thing to check is the keyword. Most SEO tools sell tracked keywords, and one keyword costs one slot, while a credit based tool sells credits that buy different jobs at different rates. A plan with 500 keywords a month sounds generous until the second site, when the slots run out and the tool asks for more money. Knowing ai seo tool pricing means knowing how many tracked keywords the monthly allowance actually covers, not just what the plan costs.
Prices in this guide are US list prices checked in November 2026, before tax. Monthly prices are per month, with the annual billing rate beside the monthly rate where the vendor publishes one. Where a vendor restructured its plans in 2026, this guide uses the current plan names instead of the old ones.
At a Glance. ai seo tool pricing in One Table
The table below is the short answer. Prices are in US dollars, before tax. Free means free to track and preview, and the paid column is what it costs to track a site without limits.
| Tool | Free plan | Entry paid price | What you get | Per keyword cost |
|---|---|---|---|---|
| Semrush | Free, 10 reports a day | SEO plan 139 dollars a month, or 117.33 dollars a month billed annually | 5 sites, 500 keywords tracked daily | About 23 cents per keyword a month |
| Ahrefs | Free for sites you own | Starter 29 dollars a month, Lite 129 dollars a month | Starter 50 keywords, Lite 750 keywords | About 17 cents per keyword a month on Lite |
| Moz Pro | 7 day trial | Starter 49 dollars a month, Standard 99 dollars a month | Standard 3 sites, 300 keywords | About 26 cents per keyword a month on Standard |
| SE Ranking | 14 day trial | Core 129 dollars a month, or 103.20 dollars a month billed annually | 10 projects, 2,000 keywords tracked daily | About 5 cents per keyword a month |
| Surfer | Free start offered | Discovery 49 dollars a month billed annually | 120 documents, content editor and scoring | About 41 cents per document a month |
| Frase | 7 day trial, no card | Starter 39 dollars a month billed annually | 10 articles, briefs and scoring | About 3.90 dollars per article a month |
| Ubersuggest | Free, limited searches | Individual 29 dollars a month | Keyword research, tracking and audits | About 29 dollars a month, flat |
| RankMath Pro | Free plugin | Pro 59 dollars a year | On page SEO, schema and rank tracking | About 4.92 dollars a month |
Read the per keyword column first, because an SEO tool without keywords is a tool that stops working mid month. SE Ranking Core gives 2,000 keywords tracked daily for 103.20 dollars a month billed annually, while Semrush SEO gives 500 keywords for 117.33 dollars, so the same money buys four times the tracking on SE Ranking. That gap between the keyword allowance and the suite is the oldest trick in ai seo tool pricing, and every tool in this table plays it in some form.
Read the billing column second, because a subscription and a per seat charge behave differently as the team grows. Semrush SEO at 117.33 dollars a month billed annually covers one user, and each extra user costs 45 dollars a month, so a team of three pays about 207 dollars a month. SE Ranking Core at 103.20 dollars a month covers one manager seat, with more seats from 16 dollars each. The billing model, not the headline price, decides what a team of three pays.
How the Billing Models Work
SEO tools sell in three ways, and the model matters more than the price. Keyword plans sell a fixed number of tracked keywords a month, so SE Ranking Core at 103.20 dollars a month billed annually buys 2,000 keywords tracked daily, which is the cheapest honest price in this guide for a site that tracks many keywords. Project plans sell a fixed number of sites, so Semrush SEO at 117.33 dollars a month buys 5 sites, which suits an agency with several clients. Document plans sell a fixed number of pages, so Surfer Discovery at 49 dollars a month buys 120 documents, which suits a content team that optimizes pages one at a time.
The second thing to check is the tracking frequency. SE Ranking and Semrush say daily on every plan, while Ahrefs and Moz say weekly on every plan, so a daily tracker shows a ranking change the next morning and a weekly tracker shows it at the end of the week. A site that reacts fast to ranking drops should check the frequency before buying, because the difference decides whether a fix happens in a day or in a week.
The third thing to check is the AI visibility add on. Semrush sells AI search tracking from the 199 dollar Starter tier, Ahrefs sells Brand Radar from 199 dollars a month, and SE Ranking includes 100 AI prompts a day in Core, while Moz includes AI visibility dashboards on every plan. That AI tracking check is part of ai seo tool pricing, because a tool that cannot show whether a site appears in AI answers is missing the question clients now ask most.
1. Semrush
Semrush is the all in one pick in this guide, and its pricing is a subscription with a free tier. The free account gives 10 reports a day, and the SEO plan costs 139 dollars a month, or 117.33 dollars a month billed annually, with 5 websites, 500 keywords tracked daily, site audit, keyword and competitor research, and AI visibility reports. Starter costs 199 dollars a month, or 165.17 dollars billed annually, and adds 50 AI prompts a day. Pro+ costs 299 dollars a month, with 15 websites and 1,500 keywords.
Worked cost for 500 keywords. The SEO plan at 117.33 dollars a month billed annually covers 500 keywords tracked daily, so 500 keywords cost 117.33 dollars in total, or about 23 cents per keyword a month. A site that tracks 500 keywords across 5 sites should pay Semrush, because 117.33 dollars a month buys the broadest suite in this guide. A site that tracks 2,000 keywords should buy SE Ranking instead, because 103.20 dollars buys four times the tracking for less money.
Semrush earns its price with breadth. It bundles SEO, PPC, content and social tools under one login, which no other tool on this list does, and the keyword and backlink databases are the largest in the category. The weakness is the per user charge, because each extra seat costs 45 dollars a month, so a team of three pays about 207 dollars a month.
2. Ahrefs
Ahrefs is the backlink pick in this guide, and its pricing is a subscription with a free tier for sites you own. Starter costs 29 dollars a month, monthly only, with 50 tracked keywords and 250 rows per report. Lite costs 129 dollars a month, or 103.20 dollars billed annually, with 750 keywords, 100,000 crawl credits and 150 AI prompt checks. Standard costs 249 dollars a month, with 2,000 keywords, and Advanced costs 449 dollars a month, with 5,000 keywords.
Worked cost for 750 keywords. Lite at 103.20 dollars a month billed annually covers 750 keywords, so 750 keywords cost 103.20 dollars in total, or about 14 cents per keyword a month. A site that lives on backlinks should pay Ahrefs, because the backlink index is the largest in the category and the Site Explorer is the tool every link builder knows. A site that only needs rank tracking should buy SE Ranking instead, because 103.20 dollars buys 2,000 keywords there.
Ahrefs earns its price with the link data. No other tool on this list shows a competitor’s backlinks as completely, and the Keywords Explorer is the standard for finding terms a site can actually rank for. A marketer who builds links every week should test Ahrefs first, because 103.20 dollars a month buys the best backlink research in this guide.
3. Moz Pro
Moz Pro is the beginner pick in this guide, and its pricing is a subscription with a 7 day trial. Starter costs 49 dollars a month for one site, and Standard costs 99 dollars a month, or 79 dollars billed annually, with 1 user, 3 sites, 300 keywords and 3 AI Visibility Dashboards. Medium costs 179 dollars a month, or 143 dollars billed annually, with 2 users and 10 sites, and Large costs 299 dollars a month, with 3 users and 25 sites.
Worked cost for 300 keywords. Standard at 79 dollars a month billed annually covers 300 keywords, so 300 keywords cost 79 dollars in total, or about 26 cents per keyword a month. A small site owner who values Moz’s authority metrics should pay Moz, because Domain Authority is the score most SEOs still quote, and the interface is the most approachable in this guide. A site that tracks more keywords should buy SE Ranking instead, because 103.20 dollars buys 2,000 keywords there.
Moz earns its price with approachability. The metrics are simple, the interface is calm, and the AI visibility dashboards on every plan show whether a site appears in AI answers, which the bigger suites charge extra for. The weakness is the weekly tracking, because rank data updates weekly and only shows the top 20 positions.
4. SE Ranking
SE Ranking is the value pick in this guide, and its pricing is a subscription with a 14 day trial. Core costs 129 dollars a month, or 103.20 dollars a month billed annually, with 10 projects, 2,000 keywords tracked daily, 250,000 audit pages a month, keyword, competitor and backlink research, one manager seat and 100 AI prompts a day. Growth costs 279 dollars a month, or 223.20 dollars billed annually, with 30 projects, 5,000 keywords and 3 seats. The AI Search add on costs 89 dollars a month.
Worked cost for 2,000 keywords. Core at 103.20 dollars a month billed annually covers 2,000 keywords tracked daily, so 2,000 keywords cost 103.20 dollars in total, or about 5 cents per keyword a month. A small agency that wants daily rank tracking and AI prompt tracking included at the entry price should pay SE Ranking, because no other suite gives 2,000 daily keywords for that money. A site that needs the largest backlink index should buy Ahrefs instead, because the link data is deeper there.
SE Ranking earns its price with the allowance. Ten projects, 2,000 daily keywords and 100 AI prompts a day for 103.20 dollars a month is the best value in this guide, and the white label reports suit agencies that send results to clients. A small agency that tracks many keywords should test SE Ranking first, because 103.20 dollars a month buys the most tracking per dollar in this guide. The weakness is the brand, because fewer clients ask for it by name than Semrush or Ahrefs.
5. Surfer
Surfer is the optimization pick in this guide, and its pricing is a subscription with a free start offered. Discovery costs 49 dollars a month billed annually, with 120 documents, the Surfy writing assistant and AI SEO optimization. Standard costs 99 dollars a month billed annually, and Pro costs 182 dollars a month billed annually, with custom voices and the Topical Map. The content editor scores a draft against the pages ranking for a target keyword, showing which terms to add and how long the piece should be.
Worked cost for 120 documents. Discovery at 49 dollars a month billed annually covers 120 documents, so 120 documents cost 49 dollars in total, or about 41 cents per document a month. A content team that optimizes pages one at a time should pay Surfer, because 49 dollars a month buys the best page scoring in this guide. A team that needs keyword research should buy Semrush or SE Ranking instead, because Surfer optimizes, it does not research.
Surfer earns its price with precision. A writer can see exactly where a draft falls short of the competition and fix it before publishing, instead of guessing why a piece did not rank. A content team that publishes every week should test Surfer first, because 49 dollars a month buys the best content editor in this guide. The weakness is the scope, because it does not track rankings or research keywords, so it is a second tool, not a suite.
6. Frase
Frase is the research pick in this guide, and its pricing is a subscription with a 7 day trial and no card. Starter costs 39 dollars a month billed annually, or 49 dollars month to month, with 10 articles, briefs, scoring and publishing to WordPress, Webflow, Sanity and Wix. Professional costs 103 dollars a month billed annually, with 40 articles and 3 seats, and Scale costs 239 dollars a month billed annually, with 100 articles.
Worked cost for 10 articles. Starter at 39 dollars a month billed annually covers 10 articles, so 10 articles cost 39 dollars in total, or about 3.90 dollars per article a month. A content team that wants research, briefs, scoring, publishing and AI visibility tracking in one place should pay Frase, because 39 dollars a month buys the best brief builder in this guide. A team that needs rank tracking should buy SE Ranking instead, because Frase researches, it does not track.
Frase earns its price with the brief. It builds a brief from the pages already ranking for a topic, showing the questions they answer and the terms they cover, then helps the writer draft against that brief. A team that publishes search content every week should test Frase first, because 39 dollars a month buys the best research workflow in this guide. The weakness is the article cap, because 10 articles a month is a small allowance for a busy blog.
7. Ubersuggest
Ubersuggest is the budget pick in this guide, and its pricing is a subscription with a free tier. The free plan covers limited searches, and Individual costs 29 dollars a month, with keyword research, rank tracking, site audits and content ideas. Higher tiers add more projects, more keywords and team seats, and the tool is built for solo site owners who want the basics without a suite price.
Worked cost for one site. Individual at 29 dollars a month covers the keyword research, tracking and audits a single site needs, so one site costs 29 dollars in total, or about 29 dollars a month flat. A solo site owner who wants the basics should pay Ubersuggest, because 29 dollars a month buys the cheapest suite in this guide. A site that tracks many keywords should buy SE Ranking instead, because 103.20 dollars buys 2,000 keywords there.
Ubersuggest earns its price with simplicity. The interface is plain, the reports are short, and a site owner can check rankings, find a keyword and audit a page in one sitting, without learning a suite. A solo owner who wants SEO without a learning curve should test Ubersuggest first, because 29 dollars a month buys the simplest suite in this guide. The weakness is depth, because the backlink data and the keyword database are thinner than Ahrefs and Semrush.
8. RankMath Pro
RankMath Pro is the WordPress pick in this guide, and its pricing is a plugin licence with a free tier. The free plugin covers on page SEO, schema and basic rank tracking, and Pro costs 59 dollars a year, with advanced schema, rank tracking, content AI and analytics. The tool lives inside WordPress, so a blogger optimizes a post in the editor, without opening another app.
Worked cost for one site. Pro at 59 dollars a year covers the on page SEO a WordPress site needs, so one site costs 59 dollars in total, or about 4.92 dollars a month. A WordPress blogger who wants SEO inside the editor should pay RankMath Pro, because 59 dollars a year buys the cheapest on page tool in this guide. A site that needs keyword research and backlink data should buy a suite instead, because RankMath optimizes, it does not research.
RankMath Pro earns its price with the fit. A blogger writes a post, checks the SEO score in the same screen, adds schema with a click, and publishes, which is the fastest on page workflow in this guide. A WordPress site owner who publishes every week should test RankMath Pro first, because 59 dollars a year buys the best WordPress SEO in this guide. The weakness is scope, because it does not research keywords or track competitors, so it is a second tool, not a suite.
Free vs Paid
The free tier is the first thing to check, and the free plans in this guide are not equal. Semrush free gives 10 reports a day, Ahrefs free covers sites you own, Moz gives a 7 day trial, SE Ranking gives a 14 day trial, Surfer offers a free start, Frase gives a 7 day trial with no card, Ubersuggest free gives limited searches, and RankMath free covers on page SEO. That split between free tracking and paid full suites is the first thing ai seo tool pricing teaches a new site owner.
The paid tier is the second thing to check, and the cheapest honest price for a suite is Ubersuggest at 29 dollars a month, while the cheapest honest price for daily tracking at volume is SE Ranking Core at 103.20 dollars a month billed annually. A site that tracks 50 keywords should pay Ahrefs Starter at 29 dollars a month and stop there, because a bigger allowance renews whether it is used or not. A site that tracks 2,000 keywords should pay SE Ranking, because the per keyword cost falls to about 5 cents.
The rule is simple. Count the keywords the site tracks in a month, divide the price by that count, and that is the per keyword cost. That per keyword figure is the heart of ai seo tool pricing, and it is the number that decides the value.
Total Cost of Ownership
The sticker price is not the total cost, and a buyer that budgets on the sticker price will be surprised in month two. The total cost includes the subscription, the extra seats, the higher tier when the keywords run out, and the cost of a ranking that drops while a weekly tracker stays silent. A 117 dollar plan with 500 keywords costs another 45 dollars per extra user, so a team of three pays about 207 dollars a month, not 117. A 103 dollar plan with 2,000 keywords costs 103 dollars forever, and that certainty is worth money to a site that tracks on a schedule.
Add the hidden costs to every tool. A ranking that drops on Monday and is only noticed on Friday costs a week of traffic, which wipes out the saving from the cheapest tool. A keyword list that runs out mid month costs an upgrade, which is the most expensive outcome in this guide. A subscription that renews at a higher rate, such as Semrush at 139 dollars monthly against 117.33 dollars on annual billing, costs 18 percent more, so commit annually or pay monthly on purpose, never by accident.
The AI visibility add on is the second hidden cost. A suite that charges 89 to 199 dollars a month extra for AI search tracking doubles the bill for a feature that SE Ranking includes and Moz includes on every plan, so a buyer who needs AI tracking should check whether it is included before buying. A site that discovers the add on after signing must pay twice or switch tools.
The rule is simple. Take the published price, work out the cost per keyword at the volume the site actually tracks, add the seats and the add ons, and that is the real yearly cost. That per keyword figure is the heart of ai seo tool pricing, and it is the number that decides the value.
Cheapest by Situation
| Situation | Best value | Why it wins |
|---|---|---|
| One site, 50 keywords | Ahrefs Starter | 29 dollars a month, monthly only |
| Daily tracking at volume | SE Ranking Core | 103.20 dollars a month annual, 2,000 keywords |
| Full suite, one user | Semrush SEO | 117.33 dollars a month annual, 5 sites |
| Backlink research first | Ahrefs Lite | 103.20 dollars a month annual, 750 keywords |
| Small site, friendly metrics | Moz Standard | 79 dollars a month annual, 3 sites |
| Optimizing pages one at a time | Surfer Discovery | 49 dollars a month annual, 120 documents |
| Research led briefs | Frase Starter | 39 dollars a month annual, 10 articles |
| WordPress on page SEO | RankMath Pro | 59 dollars a year |
Read the table by situation, not by price alone. The cheapest tool for 50 keywords is not the cheapest tool for 2,000 keywords, because the billing model flips the math. A buyer that chooses the cheapest tool and then discovers it lacks the keywords the site needs will pay twice, once for the cheap tracking and once for the replacement. That situation test is the core of ai seo tool pricing. A buyer that buys the SEO tool it needs for the site it has, with the allowance that site requires, will not pay twice.
Frequently Asked Questions
Is there a truly free AI SEO tool?
Yes, with limits. Semrush free gives 10 reports a day, Ahrefs free covers sites you own, Ubersuggest free gives limited searches, and RankMath free covers on page SEO. Moz gives a 7 day trial, SE Ranking gives a 14 day trial, and Frase gives a 7 day trial with no card. That split between free tracking and paid full suites is the first thing ai seo tool pricing teaches a new site owner.
How much does one tracked keyword cost?
One tracked keyword costs about 5 cents a month on SE Ranking Core at 103.20 dollars a month billed annually for 2,000 keywords, and about 23 cents a month on Semrush SEO at 117.33 dollars a month billed annually for 500 keywords. A consultant charges 500 to 2,000 dollars a month for SEO, and an agency charges more again for a full campaign. Count the keywords the site tracks, divide by the allowance, and that is the per keyword cost.
Do I own the data an AI SEO tool shows me?
Ownership depends on the tool and the tier. Semrush, Ahrefs, Moz and SE Ranking all let the buyer export reports on paid plans, and the exports are standard CSV or PDF files. Surfer and Frase give the buyer full rights to the briefs and drafts they make, and RankMath keeps the data inside WordPress. Read the licence on the pricing page before paying, because a report the buyer cannot share with a client is a report that will need remaking.
How much does an AI SEO tool cost in 2026?
An AI SEO tool costs 29 to 139 dollars a month on a subscription, depending on the tool and the allowance included. A consultant charges 500 to 2,000 dollars a month for SEO, and an agency charges more again for a full campaign. The tool price buys data and tracking, and the consultant price buys judgment and work. A site that needs clean tracking fast should pay the tool price. A site that needs a campaign nobody else has should pay the consultant price.
Which AI SEO tool is best for a small business?
It depends on the job. SE Ranking Core is best for daily tracking at volume at 103.20 dollars a month billed annually. Semrush SEO is best for a full suite at 117.33 dollars a month billed annually. Ahrefs Lite is best for backlink research at 103.20 dollars a month billed annually. Surfer Discovery is best for optimizing pages at 49 dollars a month billed annually. A small business that tracks 50 keywords should choose Ahrefs Starter. A small business that tracks 2,000 keywords should choose SE Ranking.
Verdict
For most small businesses, the best value is SE Ranking Core at 103.20 dollars a month on annual billing, with 10 projects, 2,000 keywords tracked daily and 100 AI prompts a day, because it is the cheapest honest price in this guide for daily tracking at volume. A site that tracks many keywords should pay 103.20 dollars and stop there. For a site that wants the full suite, Semrush SEO at 117.33 dollars a month is the best pick, because the keyword, backlink and content tools cover every job under one login.
For quality, Ahrefs Lite at 103.20 dollars a month is the best pick for backlink research, and Surfer Discovery at 49 dollars a month is the best pick for optimizing pages one at a time. For a zero budget, Semrush free, Ahrefs free and RankMath free all hand over usable tracking with no payment. The right tool is the one that fits the keyword volume, the team size, and the budget at the tier the buyer will use in six months, not at the entry price, because the entry price buys keywords that may not cover the site. That is the honest read on ai seo tool pricing in 2026.
