Before pages can rank, search engines first need to discover, understand and index them. Bilfas analyzes crawl and indexation issues, Google Search Console reports, robots rules, index/noindex signals and technical barriers that may prevent important pages from appearing in search.
Crawling is the process in which search engines, such as Google, visit website pages using bots and follow internal links to discover existing and new content. If a bot cannot find or access important pages, those pages have little chance of appearing in search results.
Indexation is the next step. After a search engine discovers a page, it evaluates whether the page should be included in its index. Only indexed pages can appear in search results.
Pages can remain outside the index for several reasons. Sometimes Google cannot find them, sometimes they are blocked by technical settings, and sometimes Google discovers them but decides they are not clear, useful or important enough to index.
Common causes include noindex tags, robots.txt blocks, weak internal linking, too many similar or thin pages, technical errors, rendering issues and unclear signals about which pages are important.
In crawl and indexation optimization, we do not only check whether a page exists on the website. We analyze whether it is accessible to search engines, internally linked, using the correct index/noindex signals, readable by Google and correctly reported in Google Search Console.
We pay special attention to pages marked as “Crawled - currently not indexed”, “Discovered - currently not indexed”, “Duplicate”, “Blocked by robots.txt”, “Excluded by noindex” or pages with other indexability issues.
Crawl & Indexation optimization includes checking the technical signals that affect whether search engines can discover, process and index important website pages.
The work may include Google Search Console analysis, index/noindex checks, robots.txt rules, internal linking review, crawl error analysis, page accessibility checks, status code review, duplicate or thin page detection and identifying technical barriers that make indexation harder.
Crawling and indexation are a core part of technical SEO. If search engines cannot discover or index important pages, quality content, strong offers and optimized titles will not be enough.
That is why we treat crawl and indexation optimization as a foundation of technical SEO stability. The goal is to help Google understand which pages are important, which should be indexed and how they are connected within the website structure.
For a broader approach to technical optimization, see our technical SEO service.
First, we analyze the current state of the website through Google Search Console, crawl tools and technical URL checks. Then we identify pages that should be indexed, pages that should not be indexed and issues that may make it harder for search engines to understand the website structure.
After the analysis, we prepare concrete recommendations for improvement. These may include changes to index/noindex rules, internal linking improvements, removing technical blocks, resolving duplicate or weak pages and better organization of priority URLs.
Crawl & Indexation optimization is especially important when a website has a large number of pages, frequent content updates, multiple languages, categories, tags, filters, URL parameters or pages that do not appear in Google Search.
This analysis is also useful after a redesign, website structure changes, new service pages or larger SEO updates. In those cases, it is important to check whether Google can actually discover and index the pages that matter most for the business.
Crawling and indexation often raise questions about why some pages do not appear on Google, what Google Search Console statuses mean and how technical issues can prevent important pages from entering the index. Below are the key questions businesses usually have before starting crawl and indexation optimization.
Crawling is the process in which Google and other search engines use bots to visit website pages, follow links and discover content. If a bot cannot find or access a page, that page has little chance of appearing in search results.
Indexation is the process in which a search engine adds a page to its database of results. Only indexed pages can appear in Google Search. If a page is not indexed, users usually will not find it through organic search.
Pages may remain unindexed because of noindex tags, robots.txt blocks, weak internal linking, duplicate or thin content, technical errors, slow loading, rendering issues or because Google does not see enough value to include them in the index.
This status means that Google visited the page but has not added it to the index. The reason may be content quality, similarity to other pages, weak internal linking, technical signals or Google’s assessment that the page is not important enough at that time.
This status means that Google knows about the URL but has not yet crawled or indexed it. This can happen on larger websites, websites with weak internal linking, crawl budget issues or when Google does not consider the URL important enough at that moment.
No. The goal is not to index every page, but to make sure that important, useful and strategically relevant pages are indexed. Filters, parameters, internal search pages, duplicates and administrative pages often should not be indexed.
If your website has important pages that do not appear in search, Google Search Console issues or unclear indexation signals, Bilfas can analyze the technical causes and suggest concrete fixes.
