Google loves speed and they actually got tired of waiting for people to speed up their sites. For this reason, they launched the AMP project. This is a special page structure which strips away some of the fancy styling to leave a much simpler page. Simpler pages load faster, and while there’s some debate in SEO circles about the ranking benefits that come with AMP, if you are running a website on budget hosting, this is almost certainly a winning concept. If you’re running a blog on WordPress, this is a relatively simple deployment, too.
Google’s aim is to provide the most relevant result for any given query. Their entire business model relies on them being able to do this, consistently, across hundreds of billions of searches. For that reason, they’ve invested heavily into understanding the intent of queries, i.e., the reason a person typed a specific thing into Google in the first place.
Organic search results are free and display below Google Ads and sometimes local results. Google uses a sophisticated algorithm to determine which sites rank highest for organic search results based on keyword usage, relevance, site design, and other factors. Generally, Google provides the highest quality, most relevant results based on the keyword(s) used by the searcher.
