What Sitebulb is for
Sitebulb audits a site and puts real effort into explaining findings and prioritising them, which is why it turns up in agencies that hand reports to clients and to developers.
What Rankelle is for
We collapse findings into causes across the whole portfolio, watch for the deploy, and compare the affected pages against a frozen control set to produce a verdict weeks later.
Where they overlap
Audit, explanation and prioritisation. Our impact score ranks causes by severity, real Search Console impressions and coverage, which is a similar idea applied to a group rather than to a page.
Running both
- Use whichever audit your team reads most fluently for the deep technical write-up.
- Keep the ledger as the record of which recommendations landed and what they did.
- Compare the two prioritisations when they disagree: ours is weighted by your own impressions, so it moves as the site's traffic does.
Do you explain findings for clients?
Yes, in plain English with each term glossed on first use, because the client report is read by people with no SEO vocabulary.
What makes a cause 'high confidence'?
Coverage. 400 of 400 pages under a pattern is a template and is stated as one; 6 of 14 is phrased as a question everywhere it appears.
Checked in September 2026 against Sitebulb's own public description of the product. Vendors ship on their own schedule; if something here has gone out of date, tell us and we will correct the page rather than leave a false statement with our name on it.

No card, and the free tier does not expire — the first verdict takes about six weeks to arrive.
