Difference b/w Crawling and Indexing in Search Engine Optimization (i.e. SEO)?

Crawling – Crawling is the discovery process in which the search engines send out a team of robots (also known as crawlers or spiders) to find out the newly updated content.


Indexing – Indexing is the process that stores the information they find in an index, a huge database of all the content they have discovered and seem good enough to serve up to searchers.



Some of the other differences between these two are –


. In the world of SEO, Crawling means “following the web link” of your website. Whereas, the indexing is the process of “adding the webpages into the Google Search”.


. Crawling is the process through which the indexing is done. For ex – Google crawls through the web pages and index the webpages. Whereas, in indexing when the search engine crawlers visit any link it is known as crawling and when the crawlers save or index that links in the search engine database then it is called as indexing.



. The process in which the Google visits your website for the tracking purpose is done by Google’s Spiders or Crawlers. Whereas, in indexing when the crawling is done, the result gets put on to Google’s index (i.e. web search), which means that Crawling and Indexing is a step by step process.


. Crawling is a process in which the search engine bots are actively crawling your website. Whereas, indexing means when the search engine bots crawl the webpages of the website and saves a copy of all the relevant information on index servers and search engines to show the relevant results on the search engine when a user performs any search query.


. Crawling finds the webpages and queues for indexing. Whereas, indexing analyses the web pages content and saves the pages with the quality of content in index.


. Crawling discovers the web crawler’s URLs recursive visits input of the webpages. Whereas, indexing builds its index with every significant word on the webpage found in the title, heading, Meta tags, alt tags, subtitles and other important positions.
