What is indexing and why might domain age matter? Indexing refers to storing pages in search engines, and while domain age isn’t a direct ranking factor, older domains often have more trust and backlinks—making them easier to crawl and index. Newer domains may face delays in indexing unless they offer high-quality, well-structured content. Whether your site is new or old, following technical SEO best practices ensures better and faster indexing. Age helps, but optimization is key.
