SEO tools have split into three jobs, and during 2026 a fourth appeared. Research platforms find keywords and backlinks. Content tools grade a page against what already ranks. Crawlers audit the technical layer. And AI-visibility tracking — monitoring whether your brand appears in ChatGPT, Perplexity, Gemini and Google AI Overviews — became a category of its own.
What changed since then is the part most guides get wrong. AI-visibility tracking arrived as a paid extra, and it has since been folded into the base plans of most of these tools. The question is no longer whether a platform has it. It is how many prompts you can track and how often they refresh — which is now what separates one price tier from the next.
Six tools below, grouped by job, with pricing taken from each provider’s own pricing page as of September 2026. Currencies differ between providers, so check before buying.
The fourth job: AI-search visibility
Traditional rank tracking asks where you sit in a list of blue links. AI-visibility tracking asks whether an AI answer cites you at all — a different question with a different answer.
Four of the six tools here now ship it, and only one still charges separately:
- Semrush includes it in every tier. Its pricing page builds AI visibility into each plan, with the allowance rising from 50 to 200 prompts tracked daily depending on the tier.
- Clearscope includes it in every plan. Under “every plan includes”, its pricing page lists prompt tracking to “track specific prompts across ChatGPT and Gemini to see when and how your brand gets mentioned”, at 50 tracked prompts on the entry plan and 300 on the tier above.
- Surfer includes it from its Standard plan up, and also sells it standalone. Its pricing page lists an AI Search Analytics plan at $82 a month billed yearly, tracking 50 prompts refreshed daily across ChatGPT, Gemini, AI Overviews and other models.
- Ahrefs is the one that still charges extra. Its pricing page lists Brand Radar AI as a specialised add-on starting at $199 a month, researching brands across what it describes as 475M+ organic prompts.
So the useful comparison is not a feature checkbox. It is the meter: how many prompts, and refreshed how often. Surfer’s ladder makes this explicit — 25 prompts on a weekly refresh at Standard, 50 refreshed daily at Pro, 100 daily above that. A weekly refresh and a daily one are different products at similar prices.
All-in-one research platforms
1. Semrush
Semrush is the broadest platform here: keyword research, site audits, backlink analysis, rank tracking and competitor research in one place, which is why agencies default to it.
Pricing runs SEO at $117.33 a month billed annually, against a regular price of $139 monthly; Starter at $165.17 annually or $199; Pro+ at $248.17 or $299; and Advanced at $455.67 or $549. The page offers a trial rather than a permanent free tier: “try Semrush free for seven days. Cancel anytime.” Additional users start at $45 a month.
The AI visibility allowance scales with the tier rather than being bought separately, which makes Semrush the simplest bill in this guide if AI tracking is part of why you are buying.
Suits: agencies and teams wanting research, technical and AI visibility under one subscription.
2. Ahrefs
Ahrefs remains the reference for backlink data, with Site Explorer, Keywords Explorer and Rank Tracker built on one of the largest link indexes available.
Its ladder starts unusually low and climbs steeply: Starter at $29 a month, then Lite at $129, Standard at $249, Advanced at $449, and Enterprise at $1,499 with an annual commitment. Annual billing saves up to 17%, and additional users cost $40 to $100 a month depending on tier. Ahrefs Free covers your own site — “get Ahrefs data on your site and fix what matters” — rather than competitor research.
Budget for Brand Radar separately. At $199 a month it costs more than the Lite plan it would sit alongside, which makes Ahrefs the most expensive route to AI-visibility tracking in this guide despite having the cheapest entry tier.
Suits: link analysis and competitor research, and anyone wanting a low-cost entry into a major suite — provided AI tracking is not the reason for buying.
Content optimisation
3. Surfer
Surfer reverse-engineers ranking pages and scores your draft in real time, with keyword clustering and an editor most writers pick up quickly.
Its plans, billed yearly, are Discovery at $49 a month with 120 documents created or optimised and 10 pages tracked; Standard at $99 with 360 documents and 25 AI prompts on a weekly refresh, plus WordPress and Google Docs integrations; Pro at $182 with 50 daily-refreshed prompts across five platforms and five brand spaces; Peace of Mind at $299 with unlimited documents and 100 daily prompts; and Enterprise at $999. The standalone AI Search Analytics plan is $82.
The entry plan is the one to read carefully: Discovery has no prompt tracking at all, so if AI visibility is the goal, Surfer effectively starts at $99 rather than $49.
Suits: bloggers and content teams optimising individual pages as they write.
4. Clearscope
Clearscope is the premium content grader, valued for clean briefs, an A-to-F grading system and a Google Docs integration that requires almost no onboarding.
Essentials is $129 a month and includes 50 tracked prompts, 50 pages, 20 monthly topic explorations and 20 monthly drafts. Business is $399 with 300 tracked prompts, 300 pages, 50 topic explorations, the same 20 drafts and a dedicated account manager. Enterprise is custom. There is a 14-day free trial, and the page states “no contracts, no hidden costs”.
Two details are worth noting before comparing it to Surfer. Drafts do not scale with the tier — both paid plans include 20 a month, with more sold as add-ons at $50 or $20 depending on volume, alongside additional pages at $25 or $15. And its prompt tracking covers ChatGPT and Gemini specifically, a narrower engine list than Surfer advertises at a similar entry price.
Suits: editorial teams where brief quality and simplicity matter more than depth of configuration.
Technical crawling
5. Screaming Frog SEO Spider
Screaming Frog does one job properly: crawling a site to surface broken links, redirect chains, duplicate content, missing metadata and sitemap issues. It is a desktop application rather than a cloud platform.
Its pricing page states that “the Screaming Frog SEO Spider is free, however you can purchase a licence to crawl more than 500 URLs and have access to advanced features”. The free version’s 500-URL crawl limit is genuinely enough for a small site.
Paid licences are £199 per year, discounted in volume: £199 each for one to four, £189 for five to nine, £179 for ten to nineteen and £169 for twenty or more. Two conditions matter for budgeting: “licences last 1 year. After that you will be required to renew”, and “licences are per user. 2 users will require 2 individual licences.” The page offers £, $ and € options, so it is not GBP-only.
Suits: technical audits at any scale, and small sites that fit inside the free crawl limit.
WordPress
6. Rank Math Content AI
Rank Math Content AI works inside the WordPress editor, suggesting keywords, improving headings and scoring on-page SEO without leaving the CMS. For a site already running the plugin, it removes a context switch rather than adding a platform.
Content AI has its own subscription, separate from Rank Math PRO. On 20 September 2026 the page displayed Starter €5.99, Creator €10.99 and Expert €16.99 per month, all billed annually excluding VAT. Displayed renewal equivalents were €6.99, €11.99 and €18.99 respectively. Confirm the current offer at checkout.
Content AI can be used with Rank Math Free. Buying the SEO plugin’s PRO plan does not by itself buy an ongoing Content AI subscription. Starter’s displayed introductory annual total is €71.88 before VAT; its displayed renewal total is €83.88. Those totals are calculated from the monthly equivalents, not monthly cancellation offers.
Suits: WordPress publishers wanting on-page guidance in the editor at a fraction of a research suite’s cost.
Comparison
Vendor-published figures as of September 2026, linked in the sections above. Currencies differ — Screaming Frog lists GBP per year, Rank Math EUR per month excluding VAT, the rest USD per month.
| Tool | Primary job | Entry price | Free option | AI-visibility tracking |
|---|---|---|---|---|
| Semrush | All-in-one research | $117.33/mo annual, $139 monthly | 7-day trial | Included, 50–200 prompts daily |
| Ahrefs | Backlinks and research | $29/mo Starter | Own site only | Add-on from $199/mo |
| Surfer | Content optimisation | $49/mo Discovery, billed yearly | — | From $99 tier; standalone $82 |
| Clearscope | Content optimisation | $129/mo Essentials | 14-day trial | Included, 50 or 300 prompts |
| Screaming Frog | Technical crawling | £199/licence/year | Yes, 500 URL limit | No |
| Rank Math Content AI | WordPress content assistance | Starter €5.99/mo equivalent; annual ex VAT; renewal €6.99/mo equivalent | Separate Content AI limits and subscription | Limited AI visibility included; scope varies by plan |
There is no ranking-improvement column. No vendor publishes a reproducible measure of ranking impact, and results depend on your site, competition and content quality rather than the tool.
What a realistic stack costs
No platform here is strongest at research, technical auditing and content grading at once, so most teams end up with two subscriptions. Using the published entry rates, the arithmetic is stark:
- Cheapest workable pairing: Ahrefs Starter at $29 plus Screaming Frog’s free crawler. Under $30 a month, with no content grading and no AI-visibility tracking.
- Content-led pairing: Ahrefs Starter at $29 plus Surfer Standard at $99 gives you research, drafting and 25 tracked prompts for about $128 a month.
- The AI-visibility trap: the same Ahrefs Starter plus Brand Radar is $228 a month — more than Semrush’s SEO plan, which includes the tracking outright at $117.33.
That last line is the practical point. If AI-visibility tracking is why you are buying, the tool with the cheapest entry tier is not the cheapest answer, and it is worth pricing the whole stack before committing to the platform you already know.
How to choose
You need keywords, backlinks and audits: a research suite, starting at the cheapest tier that covers your site count.
Your bottleneck is content quality: a content optimiser, not a research platform.
You have a technical problem: a crawler, and the free tier covers small sites entirely.
You publish on WordPress: in-editor guidance costs a fraction of a research suite and avoids a second subscription.
You are losing traffic to AI answers: compare the tracked-prompt allowance and refresh rate, not whether the feature is listed. A weekly refresh on 25 prompts is a different product from 100 refreshed daily.
Content quality still decides outcomes more than tooling — see our guide to AI writing tools, several of which now include AI-search visibility features of their own.
A small WordPress publisher’s buying decision
List the bottleneck before selecting a subscription: finding topics, crawling broken pages, drafting copy or tracking visibility. If the job is checking 40 published URLs, an AI-writing allowance is not a replacement for a crawler. If it is drafting and revising inside WordPress, Content AI may be relevant, but a plugin score does not verify the facts or prove an article is useful.
For each shortlisted plan, price one year including renewal, required add-ons and tax. Run a sample article through your editorial checks before buying volume: verify its sources, remove unsupported claims and ensure it answers a distinct reader question. A high optimization score does not guarantee search rankings.

Frequently asked questions
What is AI-search visibility tracking?
Monitoring whether AI answer engines cite your content. Semrush builds it into every plan at 50 to 200 daily-refreshed prompts, Clearscope includes prompt tracking across ChatGPT and Gemini on every plan, Surfer includes it from its $99 tier and sells it standalone at $82, and Ahrefs sells Brand Radar AI as an add-on from $199 a month.
Is AI-visibility tracking an expensive add-on?
Not any more, on most platforms. It was sold separately when it first appeared, but Semrush, Clearscope and Surfer now include it in plans. Ahrefs is the exception here, and its add-on costs more than several rivals’ entire subscriptions.
Which is cheapest to start?
For in-editor assistance, compare Content AI’s separate subscription with the tools already available in your workflow. It does not replace a backlink database or technical crawler. A low entry price is useful only if that product covers the task you need.
Why are these priced in different currencies?
Screaming Frog is a UK product listing £199 per licence per year, though its page also offers dollar and euro options. Rank Math prices in euros and excludes VAT. The rest are USD per month, so your real cost depends on the exchange rate and your local tax treatment.
Do I need both a research suite and a content tool?
Most teams end up with both, because no platform is currently strongest at research, technical auditing and content grading simultaneously. Start with whichever addresses your actual bottleneck, and price the pair before committing to either.
Which is best for WordPress?
In-editor tools reduce context switching, but can still require a separate subscription. Content AI is separate from Rank Math PRO and can run with Rank Math Free. Distinguish content assistance from crawling, keyword research and backlink analysis before buying a suite.
Conclusion
Buy for the job rather than the label. Research suites answer what to target, content tools answer whether a draft is good enough, crawlers answer what is broken, and AI-visibility tracking answers whether AI answers mention you at all.
On that fourth job, the advice has inverted over the past year. It is no longer a question of finding a tool that offers it — most now do, at no extra cost. It is a question of how many prompts you can track and how often they refresh, and of noticing that on one major platform it is still an add-on priced higher than a rival’s entire subscription.
