What is Indexing?
When Google saves your page in its vast library. If a page is not indexed, it simply does not appear in search results.
Indexing is when Google (or another search engine) finds one of your web pages, reads it, and saves it in its enormous register of everything on the web. Only once a page is indexed can it show up in search results at all.
Think of Google's index as a vast library. Google's crawlers are library assistants constantly moving around the web, reading pages (called "crawling") and shelving them with a label about what they cover. If your page is not on those shelves, it does not matter how good it is — nobody can borrow it, because it is not in the catalogue.
So there are two steps: first Google must find and read the page (crawl), then save it (index). Sometimes a page is read but still not indexed — for example if Google thinks it is too thin or a duplicate.
Why is indexing important for your business?
No indexing, no visibility. It is that simple. You can spend as much time as you like on great copy and SEO, but if your pages are not in Google's index, nobody will ever find them via search.
That is why one of the first things to check when a new website or page gets no visits is: has Google even seen and saved it? Often that is exactly where the problem lies.
Indexing in practice
Say you launch a new landing page for a campaign but notice it never appears on Google, even when you search for the exact headline. It is probably not indexed yet — perhaps because it is brand new, or because a setting accidentally told Google to ignore it.
With a free tool like Google Search Console, you can see which of your pages are indexed and even ask Google to look at a new page. It is one of the first tools every business owner with a site should know about.
Common questions about Indexing
What does indexing mean?
Indexing is when Google reads your web page and saves it in its register of the web. Only once a page is indexed can it appear in search results — otherwise it is invisible on Google.
Why is my page not indexed?
Common reasons include the page being brand new, a setting telling Google to ignore it, content that is too thin, or the page being a duplicate. Google Search Console often shows exactly why.
How do I get my page indexed?
Make sure the page is linked from the rest of your site, has its own good content, and is not blocked by settings. In Google Search Console you can also submit the page and ask Google to look at it.
