Search engines don't crawl every page on a large site every day, which means wasted crawl activity on low-value pages can delay discovery of your best content.
Identify Crawl Traps
Faceted navigation, infinite calendar pages, and endless URL parameter combinations can generate thousands of low-value URLs that consume crawl budget.
Prioritize Your Best Content in Internal Links
Pages linked from your homepage and top navigation tend to get crawled and refreshed more often, so use that placement deliberately.
Monitor What's Actually Being Crawled
Reviewing which pages search engines are spending time on versus which pages you want prioritized often reveals a mismatch worth fixing.
Next step: Use the Search Engine Spider Simulator to see your page roughly the way a crawler does.
