How this ranking works

One method for every tool. We compared documented features and published prices; we did not run hands-on tests. Value carries the most weight.

ValueFeaturesEase of use

This list is for site owners, freelancers and marketing teams comparing SEO tools on cost. It mixes full suites, a WordPress plugin, a crawler and a content tool, because most buyers need one research tool plus one specialist. Tools are ranked by value first, then features, then ease of use. Prices are the cheapest paid plan in USD as shown on each pricing page; where a page showed euros or pounds to our checker, the price is marked pending.

The verdict

Rank Math is the best value for WordPress sites, covering on-page SEO in a free plugin, with PRO adding 500 tracked keywords and schema templates. For research, Ahrefs is the strongest pick, with Starter at $29 per month and Lite at $129. Semrush costs more but adds AI visibility and ads research, and Screaming Frog's free crawler covers technical audits up to 500 URLs, with a paid licence at $279 a year.

    Best forWordPress site owners who want on-page SEO and keyword tracking for a few dollars a month.

    Rank Math earns its place by cost. The free plugin handles titles, meta descriptions, sitemaps and on-page checks, and PRO installs on top of it on annual billing. PRO covers unlimited personal websites, tracks 500 keywords, adds a schema generator with templates, a broken link checker and automated keyword linking, and includes a free trial of the Rank Math AI Starter plan. Business and Agency plans add client sites and larger keyword allowances. When we checked, the pricing page was running a sale and showed prices in euros to our checker, so the USD price of PRO is marked pending; check the page from a US location before you buy. The limit is scope. Rank Math works inside WordPress and does not offer the backlink index, keyword database or competitor research of Ahrefs or Semrush. Pair it with a research tool if you need those. We compared documented features and published prices; we did not run the plugin on a test site.

    • ✓Free plugin with no time limit
    • ✓Free version covers core on-page SEO
    • ✓PRO works on unlimited personal websites
    • ✕WordPress only
    • ✕No backlink index or competitor research on the scale of Ahrefs or Semrush
    • ✕PRO is billed annually, and the pricing page showed euros to our checker

    Best forSEOs and marketers who need backlink and competitor data.

    Ahrefs is a top research tool, and its pricing page now offers a cheaper way in. Starter costs $29 a month for keyword and competitor lookups, and Ahrefs Free gives website owners limited Site Explorer and Site Audit access. The full plans are Lite at $129, Standard at $249 and Advanced at $449 a month, with Enterprise at $1,499 on an annual commitment. Lite includes 750 tracked keywords, six months of history, 100,000 crawl credits and API and MCP access for one user; extra seats cost $40 to $80 a month each. The pricing FAQ says Ahrefs does not run discounts or free trials. Brand Radar AI adds AI search tracking from $199 a month. Data depth is excellent, but per-user pricing and add-ons push team costs up fast. We compared documented features and published prices rather than running our own audits.

    • ✓Backlink and competitor data are a core strength
    • ✓Ahrefs Free gives website owners limited Site Explorer and Site Audit access
    • ✓Starter at $29 per month is a cheap entry to Ahrefs data
    • ✕Lite at $129 per month is the first full plan
    • ✕No discounts or free trials, per the pricing FAQ
    • ✕Extra users cost $40 to $80 per month each
    Free plan:
    Ahrefs Free, limited access for your own site
    Cheapest paid plan:
    Starter, $29 per month
    Main plans:
    Lite $129, Standard $249, Advanced $449 per month
    Enterprise:
    $1,499 per month, annual commitment
    Lite limits:
    750 tracked keywords, 6 months of history, 1 user

    Bottom line: Ahrefs is the best research tool for backlink and competitor work, and Starter makes it reachable at $29. Teams should price extra seats and add-ons before choosing Standard.

    Best forAgencies and consultants who track many keywords and report to clients.

    SE Ranking is built for people who track rankings for many sites. The Core plan includes 10 projects, one manager seat, 2,000 keywords tracked daily, a 250,000-page monthly audit and 25,000 API credits with MCP access. Growth raises that to 30 projects, three seats and 5,000 keywords, and adds features such as all-time historical data. Both plans offer a 14-day free trial without a credit card. That mix suits agencies and consultants who report to several clients. Research depth is good but not at Ahrefs or Semrush level. The pricing page served euro prices to our checker, so the USD price is marked pending; check the page from a US location before you compare. We compared documented features and plan limits rather than running tracking projects.

    • ✓Strong rank tracking allowances for the plan size
    • ✓14-day free trial with no credit card
    • ✓API and MCP access on the entry plan
    • ✕Prices were shown in euros to our checker
    • ✕Extra manager seats cost extra

    Best forMarketing teams that want SEO, PPC research and AI visibility in one subscription.

    Semrush is the most complete suite here, which is why it scores highest on features and lower on value. Its pricing page lists the SEO plan at $117.33 a month billed annually or $139 monthly, the Starter SEO and AI Search plan at $199 monthly, and Pro+ at $299 monthly for multi-market teams, with up to 17% off on annual billing. The SEO plan covers five monitored websites, 500 keywords tracked daily, keyword research, competitor analysis, position tracking, site audits and AI visibility reports. That breadth makes Semrush a good fit for in-house teams running SEO and paid search together. For a solo site owner, it is a lot of tool and a large bill; Rank Math or Mangools cover the basics for less. A free account with ten reports a day and a seven-day free trial help you judge it. We compared documented features and published prices; we did not run our own projects in it.

    • ✓Broadest feature set in this list
    • ✓AI search tracking included in the entry SEO plan
    • ✓Seven-day free trial
    • ✕Entry plan costs $139 per month on monthly billing
    • ✕The SEO plan monitors 5 websites and tracks 500 keywords

    Next tiers:
    Starter SEO + AI Search $199, Pro+ $299 monthly
    Free plan:

    Bottom line: Semrush is the pick for teams that want one tool for SEO, AI search and ads research. Solo owners can get the basics for much less elsewhere.

    Mangools packages five focused tools under one subscription. KWFinder handles keyword research with search volume and difficulty scores, SERPChecker shows localized results with 49 metrics, SERPWatcher tracks rankings weekly (daily on the Agency plan), LinkMiner covers backlinks and SiteProfiler gives a domain overview. A free account and free mini tools, including a SERP simulator and an AI search grader, let you try it first. The interface is the simplest in this list, which suits bloggers and small site owners who mostly need keyword ideas. The pricing table loads by script and showed euro prices to our checker, so the price is marked pending; the plans page does state a full refund within 48 hours of payment. Heavy users will hit the limits of the backlink data sooner than in Ahrefs. We compared documented features rather than testing the tools.

    • ✓Very easy to learn
    • ✓All five tools come in one subscription
    • ✓Free account and free mini tools
    • ✕Price was not shown in USD to our checker

    Best forSmall businesses that want a guided SEO suite with clear limits.

    Moz Pro is the middle-ground suite. Its pricing page offers an entry-level plan at $49 a month for individuals managing a single website, then lists Standard at $99 a month or $79 a month when paid yearly, a 20% saving, with Medium at $179 and Large at $299 monthly. Standard includes one user, three tracked sites, 300 tracked keywords and a 400,000-page monthly crawl, plus AI features: an AI visibility dashboard with 150 tracked prompts across three AI models and two AI content briefs a month. That is a reasonable kit for a small business with one site. Moz does not offer student discounts, but it does offer a free trial and a free Moz Community account with limited access to MozBar, Keyword Explorer and Link Explorer. Against Semrush it costs less and does less; against Ahrefs Starter it gives more tracking. We compared documented features and published prices rather than testing the suite.

    • ✓Clear plan limits on the pricing page
    • ✓AI search tracking included from the Standard plan
    • ✓Free Moz Community account gives limited tool access
    • ✕Standard includes only 1 user and 3 tracked sites
    • ✕Monthly billing costs $20 more per month than yearly
    • ✕Large costs $299 per month on monthly billing
    Cheapest paid plan:
    Starter, $49 per month for a single website
    Standard:

    Yearly discount:

    Other plans:
    Medium $179, Large $299 monthly
    Free option:
    Moz Community account with limited access

    Bottom line: Moz Pro is a fair middle option for one small business site. Pay yearly to make the price competitive.

    Best forTechnical SEOs and developers auditing sites of any size.

    Screaming Frog's SEO Spider is a crawler, not a suite, and it is the cheapest way to run serious technical audits. The free version crawls up to 500 URLs and already finds broken links, duplicates and redirect problems and generates XML sitemaps. A paid licence, billed per user per year, removes the URL limit and adds scheduling, JavaScript rendering, crawl comparison and saved crawls. The licence costs $279 per user per year, about $23.25 a month, with lower rates when you buy five or more licences, which is cheap next to cloud audit tools. The trade-offs are a desktop interface with many settings and no keyword or backlink data. Pair it with a research tool. We compared documented features rather than running our own crawls.

    • ✓Free version crawls up to 500 URLs
    • ✓Paid licence costs $279 a year, about $23.25 a month
    • ✓A standard tool for technical audits
    • ✕Desktop software rather than a web app
    • ✕Steeper learning curve than any other tool here
    • ✕No keyword or backlink research
    Free version:
    Yes, up to 500 URLs per crawl
    Paid licence:
    $279 per user per year, less for 5 or more licences
    Checks:
    300+ SEO issues
    Platform:
    Desktop application
    Paid-only features:
    Scheduling, JavaScript rendering, crawl comparison, saved crawls

    Bottom line: Screaming Frog is the value pick for technical audits, with a useful free version and a $279 yearly licence. It complements a research suite rather than replacing one.

    Best forSmall agencies that need client reporting more than deep research.

    Raven Tools focuses on reporting, and its pricing reflects small agencies rather than enterprise teams. The pricing page lists Small Biz at $39 a month on yearly prepaid billing ($468 a year) or $49 monthly, with two domains, two users and 1,500 position checks. Start costs $79 yearly or $109 monthly for 20 domains and four users, and higher tiers scale to 320 domains. All accounts start with a seven-day free trial. The appeal is client reporting: audits, rankings and marketing data pulled into reports you can send. The research side is lighter than Semrush, Ahrefs or SE Ranking. For a freelancer reporting on a couple of sites, the yearly price is fair. We compared documented features and published prices; we did not build reports ourselves.

    • ✓Every plan includes more than one user
    • ✓Clear limits per plan
    • ✓Up to 30% off on yearly billing
    • ✕Small Biz covers only 2 domains and 1,500 position checks
    • ✕Research data is thinner than the large suites
    • ✕Higher tiers run from $139 to $399 per month on yearly billing

    Bottom line: Raven Tools is a reasonable reporting tool for freelancers and small agencies. Pick a research suite if keyword and link data matter more than reports.

    Best forContent teams that write and refresh articles at volume.

    Surfer is a content tool, not a full SEO suite. It scores drafts against pages that already rank and suggests terms, structure and length, and it adds an AI assistant called Surfy plus a humanizer. Plans run from Discovery, which covers 120 documents and 10 tracked pages, through Standard, Pro and an uncapped Peace of Mind tier, with AI Search Analytics as a separate product for tracking brand visibility in ChatGPT, Gemini and AI Overviews. Higher plans add plagiarism checks, internal linking suggestions and rank drop detection. That fits content teams publishing at volume. It does not replace Ahrefs or Semrush for links or technical audits. The pricing page served euro prices to our checker, so the USD price is marked pending. We compared documented features rather than writing test articles.

    • ✓Focused on writing and refreshing content
    • ✓AI search visibility add-on
    • ✓Plans range from a starter Discovery tier to unlimited optimization
    • ✕Prices were shown in euros to our checker

What to check before you pay

01

Decide which job you are paying for

SEO tools split into research suites (Ahrefs, Semrush, Moz Pro, SE Ranking, Mangools), on-page plugins (Rank Math), crawlers (Screaming Frog), content optimizers (Surfer) and reporting tools (Raven). Most small sites need one research tool and one specialist, not three suites.

02

Compare limits, not just prices

Entry plans cap tracked keywords, sites and users. Semrush's SEO plan tracks 500 keywords across 5 websites, Moz Standard 300 keywords across 3 sites and Ahrefs Lite 750 keywords for one user. Price the plan that fits your keyword count.

03

Count the seats

Per-user pricing adds up. Ahrefs charges $40 to $80 per month for each extra user depending on plan, and Moz Standard includes a single user. Raven includes at least two users on every plan.

04

Use free tiers before paying

Ahrefs Free gives website owners limited Site Explorer and Site Audit access, Semrush's free account allows 10 reports a day, Screaming Frog crawls 500 URLs for free and Rank Math has a free plugin. Semrush also offers a 7-day trial, SE Ranking a 14-day trial and Raven Tools a 7-day trial.

FAQ

What is the cheapest paid SEO tool?

Among verified USD prices, Screaming Frog's SEO Spider licence is the cheapest at $279 per user per year, about $23.25 a month. Ahrefs Starter costs $29 per month, Raven Tools Small Biz $39 per month on yearly billing and Moz's entry-level plan $49 per month. Rank Math PRO is likely cheaper, but its USD price is still pending.

Is Ahrefs or Semrush better value?

Ahrefs is cheaper to enter, with Starter at $29 per month and Lite at $129. Semrush's SEO plan costs $117.33 per month billed annually or $139 monthly but adds AI visibility reports and ads research in the same subscription.

Are there free SEO tools worth using?

Yes. Rank Math's free WordPress plugin, Screaming Frog's free crawler for up to 500 URLs, Ahrefs Free for website owners and Semrush's free account with 10 reports a day cover a lot of basic work without a subscription.

How much does Moz Pro cost?

Moz offers an entry-level plan at $49 per month for a single website. Moz Pro Standard costs $99 per month or $79 per month when paid yearly, with Medium at $179 and Large at $299 on monthly billing, according to Moz's pricing page.

How did you rank these tools?

We scored each tool on value (40%), features (35%) and ease of use (25%). We compared documented features and published prices on vendor sites and did not run our own SEO projects.
