Sitebulb

What is Sitebulb?

Sitebulb is a website crawler and technical SEO audit tool for SEO professionals, agencies and in-house marketing teams. It crawls a site, finds technical issues, and explains each one with visual reports and prioritized recommendations called Hints. The vendor says it covers 300+ SEO issues.

Key features of Sitebulb

• Prioritized Hints: Each issue comes with an explanation and a priority so you know what to fix first; Lite includes 100+ Hints and Pro and Cloud include 300+.
• JavaScript crawling: Crawls JavaScript-rendered pages, included on every plan.
• Visual reports: Crawl maps and charts show site structure, internal linking and duplicate content.
• Audit comparisons and scheduling: Pro compares audits over time and schedules recurring crawls.
• Custom PDF reports: Pro builds customized PDF reports for clients or stakeholders.
• Specialist reports: Pro adds Structured Data, International and Hreflang, Accessibility and AMP reports.
• Cloud crawling: Cloud runs in the browser with no project limits and automated recurring crawls.

How Sitebulb works

The Lite and Pro plans run as a desktop application on Windows or Mac, so crawl size depends on your machine's specifications. You enter a URL, choose crawl settings, and Sitebulb audits the site and groups findings into Hints with plain-language explanations. The Cloud plan runs the same kind of audits in a browser, which suits very large sites and shared team access. Sitebulb also offers MCP access so audit data can be used with Claude and other AI tools.

Who uses Sitebulb?

SEO consultants, agencies and in-house technical SEO teams use Sitebulb to audit client or company sites and to produce reports. Lite fits small, simple audits for one user, Pro suits larger sites up to 500,000 URLs per audit with 1 to 50 users, and Cloud is aimed at very large sites and team collaboration.

Sitebulb pricing

Sitebulb sells three plans. Lite is for one user and up to 10,000 URLs per audit. Pro allows up to 500,000 URLs per audit and 1 to 50 users, with extra users from £7 per month. Cloud starts at £95 per month for 2 or more users. Yearly billing saves 15% compared with monthly, prices can be shown in GBP, USD or EUR, and plans can be cancelled at any time. The vendor offers a 14-day trial with Pro features and no credit card.

Sitebulb integrations

Sitebulb connects to Google Analytics, Google Search Console and Google Sheets, and Cloud adds Data Studio integration. It also offers MCP access for connecting audits to AI tools.

Sitebulb alternatives

Screaming Frog SEO Spider is another desktop crawler; it is known for raw crawl data and configurability, while Sitebulb leans on explained Hints and visual reports. Ahrefs is an all-in-one SEO suite with backlink and keyword research, and its site audit is one part of a wider toolset. Moz is likewise a broader SEO platform for rankings and links rather than a dedicated crawler.
