Why 100% website indexing is impossible

Aug. 30, 2022, 12:24 a.m.

In website promotion, the problem of the impossibility of achieving full site indexation is traditionally experienced by both large web resources and medium ones with a high frequency of content updates. However, recent changes in the Crawl Stats and the Index Coverage report from Google Search Console indicate that a much larger number of Internet resources have such difficulties. IT company Golden Web Digital explains why it is impossible to achieve 100% SEO optimization and why it doesn’t create obstacles to the effective promotion of sites.

According to Google representatives, the capabilities and means of crawling and indexing each URL are increasing in proportion to the pace of expansion of the World Wide Web. However, there are a number of factors that determine Google’s ability to meet indexation demands, including: the popularity of content and URLs on the website, the speed of loading and responsiveness of the website, its novelty, and the level of Google’s perceived inventory of URLs on the website.

Before we talk in detail about the mechanism of Google's level and segment indexing, it is worth emphasizing that the popularity of a URL doesn’t always depend on the popularity of your domain or brand. Remember that non-indexed content based on uniqueness isn’t inferior in quality to other content already published on the Internet and will also be presented in search engine results.

Google uses multi-level indexing of sites, and the service index is stored in several search engine data processing centers. The HTML document of the page is marked up and stored in segments that are later indexed for quick and easy retrieval when the user searches for keywords. So, it’s worth continuing SEO promotion in the future. Although, there may be technical difficulties associated with the absence of an index, its inconsistency or the problem of the value proposition, which actually prevent Google from full indexation the site.

The «value proposition» should be understood as the value of including the proposition in the search results. It depends on the purpose of creating the page and its content quality. If your page is in the «Detected - not currently indexed» category in the Google Search Console coverage report, or has Lowest Page Quality rating, regardless of the Needs Met rating or the quality of the page design, then this indicates a lack of useful whole page as assessed by Google's QRG.

In addition, even if the user can find the page using the right keywords, but its content is repeated to content of the other resources and there is no significant informational value, then the probability of indexing the Google page also decreases. Moreover, Google has an «indexing threshold»: if the quality of the content of the page is below this threshold, it won’t be indexed. Even a previously indexed URL can lose indexing if Google finds new or better URLs.

Find out if you're having trouble with website indexing by analyzing the Google Search Console coverage graph report for the number of pages transitioning from «on» to «off». Using aggregate data, you will be able to determine which pages are indexed and which are not. It will show whether traffic or leads are decreasing and the level of loss of overall visibility and ranking in the market with the help of third-party tools. Google Search Console divides non-indexed pages into the following groups:

  • · «Scanned - not yet indexed»

Most often, such status is obtained by e-commerce and real estate websites, which regularly publish content with not new or non-unique information.

  • · «Detected - currently not indexed»

This status is obtained by websites that publish a large amount of content and create new URLs, multiplying the number of pages that will be crawled and indexed by Google. Another reason is a small crawling budget: Google considers the site unsuitable for such a large number of pages. Partially leveling the problem is possible with the help of XML and HTML website maps and internal links: this will allow to transfer the ranking from important indexed pages to the new ones.

Another reason why a website falls into this category is its content quality and availability of similar products. Google can identify patterns in URLs and conclude that HTML documents with identical URLs have a low quality and should not be crawled.

  • · «Duplicate content»

If the published content is duplicated on other websites, it won’t be indexed by Google. Moreover, content won’t be indexable if it doesn’t offer a different perspective on the subject or a unique value proposition, but simply presents information available elsewhere.

So, the main reason for the impossibility of achieving 100% indexation and optimization of the site is the need of Google to handle all existing and new content on the Internet every time. If you face the trouble identifying important content below the «indexing threshold», the IT company Golden Web in Ternopil recommend:

  • · improve internal links on pages with a lot of backlinks and those ones that rank for keywords, have good visibility and descriptive links to other pages.
  • · remove content that doesn’t bring value in the form of increased page views or conversions and isn’t indexable.
