How we grade them

Value for money
DThe SEO plan, the one Semrush aims at freelancers and small businesses, is $117.33 a month billed yearly ($139 monthly). That's in this category's dearest tenth, for one user. AI search tracking needs Starter at $165.17, and each extra person is from $45 a month.
BGraded against its alternatives. Lite is $180 a year, $15 a month, for 1 user and 10,000 URLs per audit, cheaper than Screaming Frog's $279 and far under Semrush or Ahrefs. Pro, with scheduling and comparisons, is $425 a year.
Free plan and trial
CA free account with no card: 1 project, 10 reports a day and 10 tracked keywords. Fine for a look around, but you'll hit the wall in an afternoon. The 7-day trial of the paid plans checks your card with a small charge that's refunded at once.
CNo free plan, but the 14-day trial needs no card and works like Sitebulb Pro on the desktop.
Features
BKeyword research from a database it puts at 29 billion keywords across 142 countries, competitor and backlink analysis, daily rank tracking and Site Audit. It covers the whole job, though the SEO plan only gets the basic research tools and no AI visibility.
CIt does the audit job fully: 100+ hints on Lite or 300+ on Pro, JavaScript crawling on every plan, crawl maps and MCP. But auditing is one slice of SEO, and Lite lacks scheduling, comparisons and several report types.
Ease of use
CNo rating on record. It's a big suite with a lot of reports, and there are projects to set up and plenty to learn before it all makes sense.
BNo rating on record, but this is the friendly crawler: install it, start an audit, and each problem comes ranked by priority and explained in plain terms.
Platforms and integrations
BWeb only, with no desktop or phone app. It connects to Google Analytics, Search Console, Wix, Yoast, AIOSEO, Supermetrics and Monday.com, has MCP from Starter, and the API comes with the custom-priced Advanced plan.
BDesktop apps for Windows and Mac plus Sitebulb Cloud in the browser, with Google Analytics, Search Console, Sheets, Looker Studio, Claude and ChatGPT. The cloud version is priced separately, from $125 a month.
