Sitebulb
Overview
What Sitebulb is
Sitebulb is a technical SEO auditing tool that runs as a desktop app or in the cloud. It crawls every URL on a site the way a search engine would, then reports issues across categories like indexability, internal linking, page speed, structured data, and duplicate content. Its signature feature is turning raw crawl data into prioritized "hints," each with a plain-language explanation of the problem and why it matters.
How it helps a technical SEO audit
Beyond a flat list of errors, Sitebulb builds crawl maps and link-depth visualizations that show how far pages sit from the homepage and where link equity pools or leaks. It can render JavaScript to audit dynamic sites, pull Core Web Vitals, and validate schema markup. Scheduled re-crawls let teams confirm fixes actually landed and catch regressions before they hurt rankings.
How an agency puts it to work
In our SEO and technical SEO engagements, a crawler like Sitebulb is the starting point of any audit: it surfaces the broken redirects, orphan pages, thin content, and indexing conflicts that quietly cap organic performance. With 20+ years and 700+ projects behind our in-house Houston team, we use its prioritized hints to sequence fixes by impact, so development effort goes to the issues that actually move traffic.

Sitebulb — common questions
Is Sitebulb worth it?
For agencies and in-house teams running regular technical audits, yes. Sitebulb's prioritized hints and audit scoring save hours of interpreting raw crawl data, and its visualizations make issues easy to explain to stakeholders and developers.
Sitebulb vs Screaming Frog: what's the difference?
