A search engine optimization (SEO) analysis is a report that details how a website owner can improve his or her ranking on popular search engines. Web analytics is the measurement, collection, analysis and reporting of web data for purposes of understanding and optimizing web usage. … Web analytics provides information about the number of visitors to a website and the number of page views.
Google (or any search engine you’re using) has a crawler that goes out and gathers information about all the content they can find on the Internet. The crawlers bring all those 1s and 0s back to the search engine to build an index. That index is then fed through an algorithm that tries to match all that data with your query.
SEO is also about making your search engine result relevant to the user’s search query so more people click the result when it is shown in search. In this process, snippets of text and meta data are optimized to ensure your snippet of information is appealing in the context of the search query to obtain a high CTR (click through rate) from search results.
