  • They diverge on capability: SEMrush covers Keyword research, Sitebulb covers JavaScript crawling.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

SEMrush

  • Free tier limited to 10 reports per day across all tools
  • Keyword tracking capped at 500 per month on entry tiers (SEO and Starter plans)
  • Additional users cost £45/month per user above base subscription
  • Most advanced features require Advanced plan (£455.67/month), making entry cost significant for small teams

Sitebulb

  • Desktop plans are limited to a single user, so teams need Sitebulb Cloud or paid add-on seats to collaborate.
  • Large sites near or above the 500,000 URL Pro limit require reconfiguration or the Cloud tier to avoid hitting crawl caps.
  • Desktop crawling relies on local machine resources, so audit speed and scale depend on the user's hardware rather than cloud infrastructure.
