Slow/unreliable hosting
If the host times out under crawl load, Google backs off and crawls less, and users on the page suffer too. Cheap or overloaded hosting quietly caps everything built on top of it.
What it is
Timeouts under crawl load.
Why it matters
Crawl efficiency and indexing suffer; UX harmed.
How to fix it
Upgrade hosting/CDN; monitor uptime.
How to find it on your site
- Watch server response times and error rates under real and crawl traffic.
- Check the Crawl Stats report in Search Console for elevated response times or failures.
- Load-test the slowest pages.
- Upgrade hosting, add a CDN, or cache aggressively to handle the load.
Cross-reference to ranking and citation factors
Unreliable hosting reduces crawl rate and hurts Core Web Vitals, both of which sit upstream of ranking and freshness.
Impact
Medium-high. Inferred.
