How does indexing/ranking happen?

Indexing happens with the help of crawlers. One important thing to note while creating sites is that a crawler can’t crawl web pages that only have images or other media. Crawling is done on sites that have texts. So having legible content is important in website design. The crawler gives priority when the page it crawls contains internal links that links to other pages in the main site. This helps to index the page higher. Having images and medias along with text is also a recommended practice. More contents our page have that contains texts with relevant keyphrases more chances for you to rank higher on relevant results.
