Ahrefs describes its Standard plan as aimed at freelance SEOs and marketing consultants, and its Advanced plan as aimed at lean in-house marketing teams. Ahrefs runs its own large backlink index behind Site Explorer, whereas UtilitySEO's backlink analysis is basic and its index is far smaller than Ahrefs'.

Moz

Moz offers a free Moz Community account that gives limited access to MozBar, Keyword Explorer and Link Explorer for backlink research. Moz's help documentation says Moz Pro campaign rankings update once per week, on a day set by when the campaign was first created. Moz's help documentation says on-demand site recrawls require a Medium Moz Pro plan or above, with scheduled crawls otherwise running once a week.

Screaming Frog

Screaming Frog SEO Spider connects to the Google Analytics 4, Google Search Console and PageSpeed Insights APIs to pull their data into a crawl. Screaming Frog SEO Spider does not analyse server log files itself, as Screaming Frog sells log file analysis as a separate product called the Log File Analyser. Screaming Frog SEO Spider can pull external link metrics from the Majestic, Ahrefs and Moz APIs into a crawl for content audits or link profiling.

Google Search Console

Google Search Console provides insights into website search performance and user behaviour, which can inform the development of topic clusters and content hubs, and facilitate the identification of areas for content improvement and optimisation, through its search analytics and impression data.

Sitebulb

Sitebulb's Lite plan is capped at 10,000 URLs per audit for a single user, and audit comparisons and scheduled audits are listed as Pro features. Sitebulb Cloud supports crawls of up to 10 million URLs per audit, with no project limits and automated recurring crawls, according to Sitebulb.

SE Ranking positions its Growth plan for automation and collaboration across multi-client SEO and GEO work, with 30 projects and three manager seats.

Ubersuggest Enterprise lists site audits of up to 10,000 pages per report, whereas a UtilitySEO full-site crawl covers up to 10,000 pages per crawl (depending on plan). Ubersuggest positions its Individual plan for solopreneurs growing one website, its Business plan for small and medium businesses, and Enterprise for large businesses and agencies.

Rank Math

Rank Math edits titles, descriptions and schema directly inside the WordPress editor, whereas UtilitySEO is a separate web app that syncs and publishes to WordPress through an integration.

Rank Math's WordPress.org listing includes Google Search Console and Google Analytics integrations, plus more than 30 one-click SEO tests with content recommendations.

Seobility's free Basic plan covers one website project and tracks 10 keywords, according to Seobility's pricing page. Seobility's website audit automatically crawls a site to detect technical SEO issues such as broken links, duplicate content and slow-loading pages.

Majestic

Majestic's Lite and Pro plans each include a single user, and full API access is available only on its API plan. Majestic says its Fresh Index is updated frequently throughout the day, and its links are more likely to be live than those in the Historic Index. Majestic's Topical Trust Flow shows the relative influence of a page, subdomain or root domain in a given topic or category on a 0 to 100 scale.

Raven Tools

Raven Tools pitches its plans at agencies and in-house marketing teams, with plans ranging from 2 to 320 domains or campaigns and from 2 to 40 users.
