Website development is just the beginning. In order for people to know about a web resource, it is necessary to inform the search engines about the new site. Therefore, it is extremely important to know how indexing takes place, how long it takes, and also what factors accelerate indexing, or slow it down.
What is indexing
When you first created a site, no one knows about it except you. Such a web resource is not very useful. In order for other people to know about it, it needs to be promoted. One of the ways of promotion is search engines. In order for the search engine to find out about your site, you need to add your web resource in a special way. Search engines can find out about it themselves, but this process will take much longer.
The very concept of indexing is the introduction of site pages into the search engine database.
How indexing works
Every search engine has a robot. But this is not a physical robot, but just a program that scans the Internet and detects links to new sites. A web developer can use special tags and a robots.txt file to restrict access to robots. In this case, the pages that are in the limit will not be indexed.
By adding a site to the search engine base, you only let us know that a new site has appeared. But this does not mean at all that it will be indexed immediately.
How long does it take to index
It is impossible to answer this question unequivocally. Some sites are indexed within a few hours, while others may take up to 2 weeks.
If links to the indexed site are available on resources that have already been promoted, then the pages will get into the index faster. This often happens within a couple of hours.
The same will happen if the site itself is already in search and promoted enough, and you added a new page to the site.
Competent linking will also help speed up indexing. The term "linking" means that links to pages should cross-lead to each other, but not in a chaotic manner, but in a way that would be convenient for the site user.
If the indexed resource is just beginning its existence on the Web, then the indexing time depends mainly on the search engine. This is, of course, provided that the site is made competently in terms of layout and content.
Drop out of search
If a site is indexed, this is not a guarantee that it will be permanently in the search engine database. The latter have their own specific rules and regulations. If a web resource at some point in time begins to violate these rules, then part of its pages or all of them may disappear from the search engine. In this case, a user looking for information about this particular site will not find anything.
Conclusion
Indexing is a complex process that depends on many factors. The duration of indexing can be influenced by competently compiling a robots.txt file and performing a number of other actions.
