How do Google algorithms work in search engine optimization

Google algorithm

The Google algorithm is constantly evolving. In addition to the often discussed Pagerank, Google uses over 200 other factors to determine who is number 1.

An algorithm is an unambiguous procedure for solving a problem, consisting of a finite number of steps. An algorithm is usually a process in which mathematical formulas convert certain parameters (e.g. database entries) into other parameters (e.g. sorting).

In connection with search engine optimization, the process that a search engine uses to sort the various entries in a search query is usually referred to. An example of an algorithm is the calculation of Google's PageRank.

To sort content on the Internet, Google uses a mathematical algorithm. It would not even be possible to sort the billions of Internet pages manually. Google works on the principle that manual intervention in the sorting of the results can never be objective. Google will always try to find a general solution to a problem instead of punishing or favoring individual pages.

The philosophy behind the Google algorithm is based on three principles:

  • We sort the results according to an algorithm
  • We try to answer every search query
  • We try to make the sorting as simple as possible

For more details, see The 10 Principles of Google's Test and Development Culture.

The results listed for a search query are a compilation based on the Google algorithm for evaluating websites. The algorithm takes into account Hundreds of signals to find the best results for a search query. Signals are signs of possible relevance, signals can be e.g. the terms used on a website or the level of awareness of the websites linking to a page (see also ranking criteria for search engine optimization).

The signals and the Google algorithm are constantly changing and have to be checked again and again. On average, Google makes one or two changes every day (see also Google algorithm: over 450 improvements in 2007 alone). Nevertheless, we have customers, for example, who have been in the top positions for 8 or more years. This is because the primary purpose of the changes is to identify spammers and bring forward those who have earned the top positions. If you follow the Google guidelines, you won't notice much of the changes.
