Google,s spider/crawler visits your website first.

Search engines like Google, Yahoo and Bing want to direct users to websites and content that are relevant to what they’re searching for. But how is relevancy determined?

There are four main elements that search engines look at when determining which site is more relevant and should show up higher in search engine results pages (SERPs):

Content: Is the content relevant to what the user is searching for?
Performance: Does the site load fast and does it work properly?
Authority: Is the content useful enough to link to or do other authoritative sites use that website as a reference or cite the information that’s available?
User experience: How does the site look and behave? Is it easy to navigate around? Does it look safe? Does it have a high bounce rate?
