Why Semrush wins this benchmark

Semrush won because it is the only tool that scores 9 or higher on AI search tracking, keyword data, and site audits at once. Starter ($165.17 a month billed annually) adds 50 daily AI prompts, brand sentiment, and MCP access to the keyword and audit tools, so one login covers rankings and AI answers. It does not win everywhere. Ahrefs has a better free tier for your own site and a larger link index, SE Ranking costs about $14 a month less to start, Surfer writes better content, and NeuronWriter is $23 a month. If you only write content, pick Surfer; if you want the cheapest full suite, pick SE Ranking.

  • ▸The broadest single platform here: keyword research, position tracking, site audit, and AI visibility with sentiment in one login
  • ▸AI prompt tracking is inside the core plans from Starter ($165.17/mo annual) rather than a separate purchase, with 50 prompts a day and MCP access
  • ▸Clear step-up path: 500 keywords on SEO and Starter, 1,500 on Pro+, 5,000+ on Advanced

How each criterion was scored

The overall ranking above is an equal-weighted sum of 7 criteria. Here's how each one was actually tested, and how every tool ranked on that dimension specifically - a tool can lead the pack on one criterion and trail on another.

AI Search Visibility Tracking

Rankability leads with daily tracking across 11 AI platforms on every tier, and Semrush follows with 50 daily prompts from Starter, brand sentiment, and custom prompts. Ahrefs (Brand Radar from $199 a month), SE Ranking (25 prompts a day across 5 engines), and Surfer (5 engines, mention gap, sentiment) are next. Clearscope tracks 4 engines and Frase 2 to 5 depending on plan. NeuronWriter monitors only 5 questions on Bronze. Entry plans matter: Semrush's SEO plan and Surfer's Discovery plan include no AI prompts.

Keyword & Competitor Data

Ahrefs and Semrush lead: Ahrefs runs its own crawler behind Site Explorer and Keywords Explorer in every paid plan, and Semrush tracks 500 to 5,000+ keywords daily. SE Ranking offers unlimited keyword, competitor, and backlink research on Core and tracks 2,000 keywords a day. Surfer, Frase, Clearscope, and NeuronWriter lean on SERP and competitor analysis for content rather than a large research index, and Rankability tracks only 50 to 250 Google keywords, updated weekly.

10/1010/108/106/105/105/105/105/10

Content Optimization & Drafting

Surfer leads with a live content editor, Topical Map, Content Audit, and publishing to WordPress and Google Docs. Clearscope grades drafts live in Google Docs, Word, and WordPress, and Frase drafts and publishes to WordPress, Webflow, Sanity, and Wix with an approval step. NeuronWriter adds competitor-based guidance and internal-link suggestions at a low price. Rankability ties 20 to 160 content projects a month to its tracking. Semrush, Ahrefs (AI Content Helper), and SE Ranking (AI Writer) have content tools, but writing is not their strength.

Site Audits & Technical SEO

Semrush (AI-ready Site Audit) and Ahrefs (170+ checks, free on verified sites) lead, with SE Ranking close behind at 250,000 audit pages a month on Core. Rankability runs 2 to 25 technical audits a month of up to 1,000 pages each, and Frase audits 50 to 1,000 pages. Surfer and Clearscope audit content rather than crawling the site, and NeuronWriter lists no crawler.

Price to Start

NeuronWriter leads at $23 a month ($230 a year), then SE Ranking at $103.20 a month for a full suite and Frase at $39 a month for the audit, writing, and publishing workflow. Surfer starts at $49 a month yearly (no AI prompts) and Semrush at $117.33. Ahrefs' Lite plan is $129 a month, with a $29 Starter plan for light use. Clearscope is $129 a month, and Rankability is $97 a month with its first-year allowances paid upfront.

Free Plan & Trial

Ahrefs Free (unlimited verified sites with site audits) and Semrush Free (1 demo project, 10 reports a day) are the only true free tiers. SE Ranking (14 days), Frase (7 days), and NeuronWriter (7 days) offer trials without a card. Surfer's trial length is not stated, Clearscope gives 14 days, and Rankability's 7-day trial needs a card and bills automatically.

Limits & Pricing Clarity

Frase leads: Starter holds at its limit and pay-as-you-go is opt-in with stated rates. SE Ranking, Semrush, Surfer, Clearscope, NeuronWriter, and Rankability each have traps, such as unlabeled prices, separate AI plans, units that are not defined, or allowances that do not roll over. Ahrefs scores lowest because Brand Radar is a $199 add-on, extra users are $40-$80 a month each, and every prompt check is counted by platform and location.

#1

Semrush

Winner

An all-in-one SEO platform that now tracks AI search visibility and brand sentiment alongside keyword research, rank tracking, and site audits.

52/70
benchmark score

Strengths

  • +The broadest single platform here: keyword research, position tracking, site audit, and AI visibility with sentiment in one login
  • +AI prompt tracking is inside the core plans from Starter ($165.17/mo annual) rather than a separate purchase, with 50 prompts a day and MCP access
  • +Clear step-up path: 500 keywords on SEO and Starter, 1,500 on Pro+, 5,000+ on Advanced

Weaknesses

  • -The entry SEO plan lists no AI prompts, so tracking AI answers means paying at least $165.17 a month billed annually
  • -Keyword and website limits climb quickly: 500 tracked keywords on both SEO and Starter
  • -SSO, team governance, and audit logs appear only on Enterprise, and extra users cost $45 a month each

Heads up: The prices on the pricing page are the annual-billed monthly rate. Monthly billing costs about 18-21% more, so compare like with like when you set it next to Ahrefs or SE Ranking.

Free is $0 with no card: 1 demo project and 10 reports a day. Semrush also offers a 7-day free trial on paid plans. SEO is $117.33 a month billed annually ($139 monthly) for 5 websites and 500 keywords tracked daily, with no AI prompts. Starter is $165.17 annually ($199 monthly) and adds 50 AI prompts a day, 1 domain for AI brand performance, and MCP access. Pro+ is $248.17 annually ($299 monthly) for 15 websites, 1,500 keywords, and 100 AI prompts a day. Advanced is custom-priced with 40+ websites, 5,000+ keywords, and unlimited daily prompts. Extra users start at $45 a month. Standalone AI Visibility plans sit on a separate pricing tab that we did not price (checked 9 November 2026).

#2

Ahrefs

An SEO toolset built on Ahrefs' own web crawler, with Site Explorer, Keywords Explorer, site audits, and a Brand Radar add-on for AI search visibility.

51/70
benchmark score

Strengths

  • +The best free tier for site owners: Ahrefs Free audits unlimited verified websites with 170+ technical and on-page checks
  • +Deep data on competitors: Site Explorer and Keywords Explorer sit in every paid plan, backed by its own crawler
  • +AI tracking is optional and transparent: Brand Radar AI starts at $199 a month and prompt packages list their per-check overage rates

Weaknesses

  • -Brand Radar AI is a separate add-on from $199 a month, so full AI tracking costs more than the plan price suggests
  • -Only 1 user is included, and extra users cost $40-$80 a month each
  • -Lite caps AI prompt checks at 150 a month, and each prompt on each platform in each location uses one check

Heads up: Ahrefs Free only works on websites you own and can verify. To look at a competitor you need a paid plan, and the $29 Starter plan is the cheapest way in.

Ahrefs Free (formerly Webmaster Tools) covers unlimited verified websites with Site Audit (170+ issue checks, 5,000 crawl credits a month per project), Web Analytics, and Site Explorer limited to 1,000 backlinks and keywords. Starter is $29 a month. Lite is $129 a month for 750 tracked keywords, 150 AI prompt checks, 6 months of history, and 100,000 crawl credits. Standard is $249 (2,000 keywords, 300 checks, 500,000 crawl credits) and Advanced is $449 (5,000 keywords, 600 checks, 1.5 million crawl credits). Each includes 1 user; extra users are $40, $60, or $80 a month depending on the plan. Brand Radar AI is an add-on from $199 a month, and custom prompt packages run $50, $100, or $250 a month. Ahrefs says annual billing saves up to 17% (checked 9 November 2026).

#3

SE Ranking

An SEO platform for agencies and in-house teams that bundles rank tracking, audits, research, and AI search trackers at a lower entry price than Semrush.

50/70
benchmark score

Strengths

  • +The lowest entry price of the three full SEO suites: $103.20 a month billed annually against Semrush's $117.33 and Ahrefs' $129
  • +Built-in AI trackers for AI Overviews, AI Mode, ChatGPT, and Gemini, with 25 AI prompts a day on Core
  • +Unlimited users on every plan and a 14-day trial with no card

Weaknesses

  • -Features are tied to tiers rather than sold individually, so the $279 Growth plan is the jump if you need history beyond 6 months
  • -Annual plans are billed upfront and cannot be paid monthly without contacting sales
  • -Only 25 AI prompts a day on both Core and Growth, and broader AI tracking means the separate SE Visible add-on

Heads up: The pricing page shows two numbers per plan without labeling which is annual. Core is $103.20 on annual billing and $129 on monthly billing; do the same check on Growth before you compare totals.

A 14-day free trial needs no card and includes up to 10 projects, 750 tracked keywords a day, 20 AI prompts a day, and AI competitive research for up to 3 domains. Core is $103.20 a month billed annually ($129 monthly) for 10 projects, 2,000 keywords tracked daily, 250,000 audit pages a month, 25 AI prompts a day across 5 AI engines, and MCP access. Growth is $223.20 annually ($279 monthly) for 30 projects, 5,000 keywords, 2 million audit pages, and all-time history. Users are unlimited on both. SE Visible, a separate AI add-on, starts at $71 a month. The page does not label which price is annual; the 20% annual discount it states matches our reading (checked 9 November 2026).

#4

Frase

A content workflow tool that audits your site, drafts and publishes articles, and tracks AI visibility across up to five AI engines, with opt-in pay-as-you-go overage.

49/70
benchmark score

Strengths

  • +The cheapest all-in-one content workflow here at $39 a month billed yearly, with audit, writing, publishing, and AI tracking
  • +Caps are explicit: Starter holds at its limit with no surprise overage, and pay-as-you-go is opt-in
  • +Publishes to WordPress, Webflow, Sanity, and Wix, with an MCP server and CLI for Claude, ChatGPT, and Cursor

Weaknesses

  • -Starter has only 20 AI prompts and covers ChatGPT and Google AI; Perplexity needs Professional and Claude and Gemini need Scale
  • -Starter shows current data only, with 3 months of history from Professional
  • -The agent can auto-publish during the trial, and AI visibility does not auto-fix issues

Heads up: The 7-day trial runs on Professional-level features with its own caps (5 articles, 50 audit pages, 25 AI prompts, 3 seats), and the agent can auto-publish. Turn auto-publish off before you connect a live site.

A 7-day free trial needs no card. Starter is $39 a month billed yearly ($49 monthly) for 10 articles, 50 audit pages, 25 AI generations, 1 seat, 1 domain, and 20 AI visibility prompts across ChatGPT and Google AI. Professional is $103 yearly ($129 monthly) for 40 articles, 250 audit pages, 3 seats, 5 domains, and 50 prompts adding Perplexity. Scale is $239 yearly for 100 articles, 1,000 audit pages, 5 seats, 10 domains, and 75 prompts adding Claude and Gemini. Extra seats are $29 a month. Pay-as-you-go overage is off by default: $5 per extra article and $0.25 per extra AI prompt on Professional. Publishing goes to WordPress, Webflow, Sanity, Wix, or FraseCMS (free to 100,000 page views a month) (checked 9 November 2026).

Surfer homepage screenshot
#5

Surfer

A content-optimization platform (formerly Surfer SEO, now at surfer.ai) that pairs a live content editor with AI answer tracking across five engines.

46/70
benchmark score

Strengths

  • +The strongest writing workflow here: live content editor guidelines, Topical Map, Content Audit, and a re-optimization loop
  • +Tracks visibility, mentions, and sentiment across ChatGPT, Gemini, Perplexity, AI Mode, and AI Overviews, with a Mention Gap report
  • +Publishes to WordPress and Google Docs from Standard, and offers an MCP server in Claude and ChatGPT

Weaknesses

  • -The entry plan (Discovery, $49) tracks no AI prompts, and Standard's 25 prompts are ChatGPT only
  • -Not a full SEO suite: no site crawler or backlink index is listed on the pricing page
  • -Annual plans are charged upfront for the year, PayPal is not accepted, and support is 24h on weekdays only

Heads up: The headline prices are yearly-billed monthly rates, and the monthly-billed prices are not on the page. Multi-engine AI tracking starts at AI Search Analytics ($82) or Pro ($182), not Standard.

Plans are listed at the yearly-billed monthly rate. Discovery is $49 a month for 120 documents, 10 tracked pages, and 0 AI prompts. Standard is $99 for 360 documents, 50 pages, 3 seats, and 25 AI prompts tracked in ChatGPT only, refreshed weekly. Pro is $182 for 360 documents, 200 pages, 5 seats, and 50 prompts refreshed daily. Peace of Mind is $299 for unlimited documents under a fair-use policy, 500 pages, 10 seats, and 100 prompts. AI Search Analytics is $82 a month for 50 prompts across 5 workspaces and 5 seats. Monthly-billed prices are not shown on the page. Every plan button says Start for Free; trial length is not stated. Annual plans are charged for the full year (checked 9 November 2026).

#6

NeuronWriter

A low-cost content-optimization platform with competitor analysis, an AI writing assistant, and AI visibility monitoring for questions across Google, AI Overviews, ChatGPT, and Perplexity.

42/70
benchmark score

Strengths

  • +The lowest price here: Bronze is $23 a month, or $230 a year, for content analysis, AI writing, and internal-link suggestions
  • +Covers AI visibility monitoring on Google, AI Overviews, AI Mode, ChatGPT, and Perplexity on the lowest tiers
  • +Includes unlimited team members, an API, and MCP access from Gold at $69 a month

Weaknesses

  • -Hard caps on every plan: only 5 AI-monitored questions and 25 documents on Bronze
  • -No site crawler or rank tracking is listed on its pages, so it covers writing, not the full SEO workflow
  • -Sharing is read-only on Bronze and Silver, and several integrations, the Content Designer, and plagiarism checks need Gold or higher

Heads up: The free trial uses Gold plan terms, but the advertised price is Bronze. You may find features in the trial that are missing on the plan you buy, and the refund right covers only the first plan purchased within 30 days.

The 7-day free trial runs on Gold plan terms and needs no card. Bronze is $23 a month ($230 a year) for 2 projects, 25 documents, 5 AI-monitored questions, and 15,000 AI credits. Silver is $45 ($450 a year) for 5 projects, 50 documents, and 7 questions. Gold is $69 ($690 a year) for 10 projects, 75 documents, 10 questions, 45,000 credits, unlimited team members, and the Content Designer and API. Platinum is $93 and Diamond $117 a month. Annual billing gives 2 months free. WordPress, Search Console, Shopify, and your own OpenAI key are listed as integrations, with Shopify and the OpenAI key explicitly from Gold (checked 9 November 2026).

#7

Rankability

An AI search optimization platform that tracks brand visibility daily across 11 AI platforms and ties it to content projects, page audits, and technical audits.

40/70
benchmark score

Strengths

  • +The widest AI-engine coverage: 11 platforms including ChatGPT, Google AI Mode, AI Overviews, Claude, Perplexity, Gemini, Grok, Copilot, and DeepSeek, tracked daily on every tier
  • +Search tracking, page audits, technical audits, and content production in one workflow
  • +Unlimited users and workspaces, with API and MCP access on every paid plan

Weaknesses

  • -The most expensive way to start for a small site: $97 a month with a card-required trial and no free plan
  • -Google rankings update weekly and cover the top 30 results, and Starter tracks only 50 keywords
  • -Each allowance (AI queries, keywords, Local Pack scans) is separate, and a keyword in another location or language uses another slot

Heads up: Annual plans pay for 12 months of allowance upfront, with no monthly refill and no rollover. Burn through it early and you wait for next year, so a monthly plan is safer for your first quarter.

There is no free plan. A 7-day free trial is available on monthly plans only, needs a card, and bills automatically unless you cancel. Starter is $97 a month ($970 a year) for 20 content projects a month, 100 tracked AI queries, 50 tracked Google keywords, 20 page audits, and 2 technical audits of up to 1,000 pages each. Growth is $297 ($2,970 a year) for 80 projects, 300 queries, and 150 keywords. Pro is $497 ($4,970 a year) for 160 projects, 500 queries, and 250 keywords. Users, workspaces, API, and MCP access are unlimited or included on every paid plan. Annual plans get 12 months of allowance upfront with no rollover (checked 9 November 2026).

#8

Clearscope

A content-grading platform that finds the questions buyers ask, tracks whether Google, ChatGPT, Gemini, and Claude mention you, and grades drafts as you write.

38/70
benchmark score

Strengths

  • +Unlimited users and projects on every plan, which suits editorial teams that grow
  • +Writes to a live content grade in Google Docs, Microsoft Word, and WordPress, with term guidance
  • +Tracks mentions of you and competitors across Google, ChatGPT, Gemini, and Claude, with the answers readable

Weaknesses

  • -The most expensive entry price here at $129 a month, and no free tier
  • -Drafts are capped at 20 a month on both Essentials and Business
  • -No site crawler or technical audit is listed, and annual pricing is not published

Heads up: The add-on table gives no units for Drafts and does not say whether a block is billed monthly or once. Ask support what a block costs and whether it renews before you add one.

Clearscope has a 14-day free trial and no free tier. Essentials is $129 a month for 50 tracked queries, 50 pages, 20 monthly Discoveries, and 20 monthly Drafts. Business is $399 a month for 300 tracked queries, 300 pages, 50 Discoveries, 20 Drafts, and a dedicated account manager. Enterprise is custom with SSO and crawler whitelisting. Users and projects are unlimited on every plan. Add-ons: extra Tracked Queries in blocks of 10 ($6.50 on Essentials, $5.50 on Business), Pages in blocks of 100 ($25 or $15), and Drafts in blocks of 10 ($50 or $20). There is no minimum contract on monthly plans; annual prices are not published (checked 9 November 2026).
