What is a search engine?
Search engines are services that can be used to search the Internet. Large data sets can be sorted using keywords and filtered according to specific search results. The search engine refers to indexed content that matches a search query. On the Internet, these are usually websites on which content such as texts, images or links are made available.
How did search engines come about?
The development of search engines dates back to 1990. However, it was not the world-famous Google search engine that was founded in this year, but Archie. However, Archie is not comparable to search engines as we know them today. The Archie service focused on analyzing folders and files. These were usually located in FTP directories. By the standards of the time, the Archie search engine had an enormously high number of hits. The first search engines, which were similar to today’s services, were used in libraries and helped to explain complex terms.
What is the goal of a search engine?
Google’s search engine aims to always find the most relevant and best answers and results to a specific search query. To ensure this, each page is evaluated individually by the Google search engine crawler in order to reliably assess its relevance. The Google algorithm evaluates the pages based on more than 200 criteria and then decides in which position a page is displayed.
How does a search engine work?
Search engines have enormous amounts of data in the form of documents. When a user submits a search query, the algorithm searches all available pages for corresponding keywords that are also included in the search query. The higher a page is ranked for a corresponding keyword, the higher it is displayed in the search query. As most visitors to a search query only look at the search results on the first page, the search engine optimization of a page should go so far that the page appears in the first results for selected keywords. This is the only way to ensure that enough visitors land on a website organically through search queries.
How does a search engine rate the quality of a page?
Google evaluates every page according to strict requirements and site operators must ensure that these criteria are met so that a page is displayed as high up as possible in the top results. To be considered a relevant and high-quality page by Google, unique and high-quality content should be found on the page. Keyword density and user-friendliness should also be at a high level.
How can a page be optimized for search engines?
If a website is to be optimized for search engines, it is usually necessary to make some optimizations to the page structure. Content also needs to be updated and upgraded frequently in order to keep feeding the algorithm with new data. If a page is not supplied with fresh data over a longer period of time, this will have a noticeable effect on the Google ranking.
Who should optimize a page for search engines?
If the website operator has the relevant knowledge, the optimizations can be carried out themselves. However, if the changes are to be placed in professional hands, an online marketing agency can be commissioned. These are usually professionals who know exactly what to look out for during optimization.
