SEO AUDIT TOOL PRICING, COMPARED
Pay once. Keep auditing.
Most site audit tools charge every year or every month. SiteAuditLint Pro is $99, one time. Here is what that looks like next to Screaming Frog, Sitebulb, Ahrefs and Semrush.
100 URLs free. No credit card required.
What one seat costs over 3 years
List prices in USD, one user, cheapest billing option each vendor offers.
Ahrefs and Semrush are all-in-one suites that include keyword and backlink research, so their price covers more than site audits. See the notes below.

How the pricing model affects you
The sticker price matters less than what happens when a renewal lapses, where your crawl data lives, and what you are paying for beyond site audits.

Head-to-head SEO crawler comparisons
Price is one part of the decision. These three-way comparisons go deeper on technical SEO features, crawl limits and audit workflows.
Screaming Frog vs Ahrefs vs SiteAuditLint
A desktop crawler against a cloud-based Site Audit: crawl credits, Ahrefs Webmaster Tools for verified sites, keyword and backlink research, and the total cost of ownership for technical audits.
Screaming Frog vs SE Ranking vs SiteAuditLint
Desktop crawling against SE Ranking's cloud Website Audit: pages audited per plan, rank tracking bundled with site audits, scheduled recrawls, and client reporting for agencies.
Screaming Frog vs Semrush vs SiteAuditLint
Desktop technical crawling against an all-in-one SEO and marketing platform: Site Audit page limits, Pro vs Guru plans for historical data, and tracking fixes between audits.
Screaming Frog vs Seobility vs SiteAuditLint
A browser-based SEO checker against two desktop crawlers: Seobility's free plan and project crawl limits, on-page optimization scores, and running audits without installing software.
Screaming Frog vs Sitebulb vs SiteAuditLint
Three desktop SEO crawlers side by side: indexability and canonical tag checks, redirect chains, crawl limits per audit, visual audit reports, and how each tool tracks audit history.
Sitebulb vs Ahrefs vs SiteAuditLint
A dedicated audit crawler against a backlink platform: Sitebulb Hints prioritisation, Domain Rating, backlink data vs on-page audits, and the cost of running both.
Sitebulb vs Semrush vs SiteAuditLint
A dedicated audit crawler against an all-in-one platform: the Semrush Site Health score vs audit depth, Sitebulb Cloud, audit report exports, and what keyword research bundling costs.
Ahrefs vs Semrush vs SiteAuditLint
The two big research suites side by side: backlink index and keyword database size, content toolkits, user seat pricing, and where a dedicated audit crawler fits.
Screaming Frog vs JetOctopus vs SiteAuditLint
Two desktop crawlers against a cloud crawler: crawl speed at scale, local RAM limits, JavaScript page costs, and licence vs monthly page allowance.
When another tool is the better fit
A straight answer, so you buy the right thing the first time.
You need keyword and backlink data
Ahrefs and Semrush are research suites first. If competitor keywords, backlink profiles and rank tracking are the job, a suite earns its monthly fee. SiteAuditLint pairs well alongside one for technical audits.
You audit on a Mac or Linux
SiteAuditLint runs on Windows today. Screaming Frog runs on Windows, macOS and Linux, and Sitebulb desktop runs on Windows and macOS.
Your team needs a shared cloud crawler
If several people need the same crawl data in a browser, a cloud plan like Sitebulb Cloud, Ahrefs or Semrush is built for that. SiteAuditLint keeps every audit local to one machine by design.
Competitor prices are public list prices in USD for one user, checked September 2026. See the vendors' own pages: Screaming Frog, Sitebulb, Ahrefs, Semrush. Prices change and vary by region and tax. All trademarks belong to their owners.

Pricing questions
What people ask when they compare SEO audit tools.
Is SiteAuditLint really a one-time payment?
Yes. Pro is $99 and Agency is $159, each paid once. There is no subscription, no license key and no annual renewal to keep auditing. The Free plan costs nothing and crawls up to 100 URLs per crawl.
How does SiteAuditLint pricing compare to Screaming Frog?
Screaming Frog SEO Spider is an annual licence at $279 per user per year (£199), with a free version capped at 500 URLs. SiteAuditLint Pro is $99 once. Over three years that is $99 against $837 for a single Screaming Frog seat.
How does it compare to Sitebulb?
Sitebulb desktop is a subscription with no permanent free plan, only a 14-day trial. Lite starts around $18 a month and Pro around $42 a month on monthly billing, with lower rates billed annually. Lite is capped at 10,000 URLs per audit.
Why are Ahrefs and Semrush so much more expensive?
They are all-in-one SEO suites. Site audit is one tool inside a platform that also covers keyword research, backlink analysis and rank tracking. Ahrefs Lite is $129 a month and Semrush Pro is $139.95 a month on monthly billing. If you only need technical SEO audits, you pay for a lot you won't use.
Is SiteAuditLint a replacement for Ahrefs or Semrush?
Not entirely. SiteAuditLint is a site audit tool: crawling, scoring, an Action Plan, audit comparison and AEO/GEO checks. It does not do keyword research or keep its own backlink index, though Pro can import backlink exports from Ahrefs or Semrush to find broken pages that still have links. Many teams pair a suite for research with a dedicated crawler for audits.
Where do the competitor prices come from?
List prices in USD from each vendor's public pricing, checked in September 2026, for one user. Where a vendor offers annual billing, the cost chart uses the annual rate, which is the cheaper option. Prices, currencies and taxes vary by region and change over time, so confirm on the vendor's site before buying.
