What is Index Bloat?
Search indexes filling with low-value URLs: facets, parameters, tag archives, thin search pages. Bloat wastes crawl budget and dilutes quality signals, so audits segment the index by template and prune deliberately.

Index Selection
The engine’s choice of which crawled pages to keep, favoring unique value and quality signals. Selection is why thin duplicates vanish from the index while consolidated canonicals survive.
Faceted Navigation
Filter URLs (color, size, price) that multiply crawlable combinations. Controls include noindexing thin facets, canonicalizing to parents, and parameter handling in Search Console.
Content Pruning
Removing or consolidating low-value pages to concentrate crawl budget and signals. Prune with redirects and internal-link updates, never by deletion alone.
Technical SEO
The crawling, indexing, rendering, and performance work that lets search engines reach, understand, and serve your pages. It covers directives, architecture, speed, and structured data rather than words on the page.
Crawling
How search-engine bots discover pages by following links, sitemaps, and directives. If a URL is never crawled, it cannot be indexed no matter how good its content is.
Crawl Budget
The number of pages a search engine will crawl on a site in a given period, driven by server capacity and demand signals. Large or slow sites must spend it on indexable, valuable URLs.
