When you input a search query into a search engine you receive a Search Engine Results Page (SERP) showing results relevant to your query. These results are not a live. Instead, they are pulled from the most recent index created by the search engine you are using. Search engines periodically crawl the internet to create these indexes. For example, Google’s web crawlers (known as “GoogleBots”) crawl the internet every 7-14 days.
When crawling, web crawlers review specific elements of your website in order to determine relevance to keywords and Search Engine Friendliness (SXE). The higher your relevance to a query and the higher your search engine friendliness, the higher you will rank. We optimize these on-page elements to ensure search engine friendliness.
