Sitebulb is a desktop crawler with detailed visualisations. AuditZap is cloud-based with AI fix instructions.
Improve Largest Contentful Paint
Ensure the largest contentful element loads quickly. Consider reducing server response time, removing render-blocking resources, and optimising images.
You now know what's wrong. Diagnosing the theme, plugin, or build step behind it - and the actual fix - is on you.
Convert your hero image and prioritise it
Your hero image (hero-banner.jpg, 1.8 MB) is the LCP element. Convert it to WebP, resize to 1200px wide, and add fetchpriority="high". Move the Google Fonts link to a preload tag.

Frequently asked questions
Is AuditZap a good Sitebulb alternative?
It is if you want a quick cloud audit that writes the fix, rather than a desktop crawler built for deep technical analysis. AuditZap needs no install and returns AI fixes per issue. Try the free broken link checker to see the output.
Does Sitebulb have a free version?
Sitebulb is a paid desktop tool with a free trial rather than a permanent free tier. Once the trial ends you need a licence to keep crawling.
Can AuditZap crawl large sites like Sitebulb?
AuditZap is built for focused audits of up to 50 pages per crawl, so it returns a prioritised fix list fast; Sitebulb is designed for hundreds of thousands of pages with visual crawl maps. For a large technical crawl Sitebulb is the better fit; for a quick, prioritised fix list on a small site, use AuditZap and the website audit checklist.
Does AuditZap explain how to fix what it finds?
Yes. Each issue includes a plain-English, platform-aware fix and an estimated revenue impact. See the image optimisation checker for the style of guidance.
Does AuditZap check AI search visibility?
Yes. AuditZap runs 9 AI-visibility checks (llms.txt, AI crawler access, citation schema and more) that desktop crawlers do not cover. Run the free AI visibility checker.
