Search engine works on three things:

  1. Crawling
  2. Indexing

A search engine crawler is continuously searching for fresh and updated content on the web. Content can be in any form like article, image, pdf, video, etc. For crawler to crawl images they should have an image name and alt tags as crawler cannot read the images. Crawler identifies images by its alt tag.

When user searches something on search engine results are displayed from most relevant to least relevant result. This relevancy depends upon what was users search query.

These results are pulled out from indexed database of a search engine.

Page speed is another important factor to consider. If your website page loads at blazing speed more users will be engaged more on your site. It helps to improve your website ranking.

If your site takes more than 1-2 seconds to load a page user will bounce back to other search results increasing your bounce rate and lowering your ranking on search result pages.
