The Lowdown on Search Engine Indexing

The Lowdown on Search Engine Indexing

We have been using indexes for many years in order to find services and businesses that we would like to consult. After all, the Yellow Pages itself is an index! Nowadays, the majority of people tend to look to Google instead because the internet is convenient and, for the most part, reliable. Search engines have their own way to index information for us so that we can find the most relevant results in as little time as possible. Read on as we explain what search engine indexing is… In layman’s terms, indexing is the name given to the process that search engines carry out in order to organise the information on the internet so that users can find it with as much ease as possible. After all, they want us to be able to source the answer to our query quickly. As a result, the results that a user is often provided with have been narrowed down in order to align with certain locations and particular phrases, known as keywords. It is carried out this way because it would take the user too much time to manually search through hundreds of thousands of search results based on a particular area or service. Many search engines, including Google, use what is known as a ‘reverse index’ in order to identify relevant information. This is an intelligent system that compiles a database of text elements and the search engines then use a process called Tokenisation in order to reduce them to their core meaning as this simultaneously reduces the resources necessary to store and retrieve any data, allowing the information to be found by specifics like location and keywords instead. Another method that search engines may use when indexing a new page is storing a cached version of it. This is a highly-compressed text only version which includes the HTML and meta data, and is effectively the latest snapshot that the search engine knows about stored as a backup. This is also the version that has been indexed and will be used to judge its relevance for a user’s search query until the next time the page is cached. The user doesn’t have to worry about indexing because all of this hard work goes on behind the scenes as a result of Google’s in-depth and highly optimised algorithms. With this said, SEO technicians such as ourselves are well-versed in the indexing process that takes place. After all, it allows us to understand what the search engines are looking for and design our campaigns accordingly and ethically.
