How Search Engines Work
Search engines have one objective – to provide you with the most relevant results possible in relation to your search query. If the search engine is successful in providing you with information that meets your needs, then you are a happy searcher. And happy searchers are more likely to come back to the same search engine time and time again because they are getting the results they need.In order for a search engine to be able to display results when a user types in a query, they need to have an archive of available information to choose from. Every search engine has proprietary methods for gathering and prioritizing website content. Regardless of the specific tactics or methods used, this process is called indexing. Search engines actually attempt to scan the entire online universe and index all the information so they can show it to you when you enter a search query.How do they do it? Every search engine has what are referred to as bots, or crawlers, that constantly scan the web, indexing websites for content and following links on each webpage to other webpages. If your website has not been indexed, it is impossible for your website to appear in the search results. Unless you are running a shady online business or trying to cheat your way to the top of the search engine results page (SERP), chances are your website has already been indexed.A few factors that a search engine algorithm may consider when deciding what information to show in the SERP include: Geographic
- location of the searcher
- Historical performance of a listing (clicks, bounce rates, etc.)
- Link quality (reciprocal vs. one-way)
- Webpage content (keywords, tags, pictures)
- Back end code or HTML of webpage
- Link type (social media sharing, link from media outlet, blog, etc.)
