First of all, let’s know what Crawlers are.
Search engines need to know that the websites (that are searchable in their database) have whether updated any content recently or not. So, to do that Search engines have special programs that inspect newly added content to a website. Such programs are known as Crawlers.
Why are Crawlers important?
Without Crawlers, your recently updated content can never be submitted to search engines and probably never be visited by anyone. Crawlers are what make your content indexed to Search Engine’s database.
How social media plays an important role in prioritizing the websites for crawling?
Before starting, it is important to know that Google has not officially stated that they use social media in deciding which URL to crawl first. But Bing has stated it officially and takes social media as one of the prominent factor in deciding which URL to crawl first. But some experts (SEO consultants and social media analysts) believe Google does it, too. Especially, after Google plus was founded, it’s more likely that Google also uses social media to some extent for crawling.
Be it Google or Bing or any other search engine company, every one of them wants to index the best materials/resources in their first couple of results.
Why shouldn’t they? It is their central function; to provide the users with the BEST. So, for that, the search engines first need to be sure of what they are posting as BEST really is BEST.
Gone are the days when social media like Facebook and Twitter were just there to share tweets/updates and add friends/followers. The social media has drastically changed over the years. With almost 90% over the internet users enmeshed, social media easily know what’s HOT among the people and what the current trend in the market is!
That’s exactly what search engines are looking for! They want to know what people prefer most and what is best in the market, so as to accordingly list them in their search results.
How it works?
Whenever a URL is shared in a social media, usually search engines look for two things:
- How active is the person who has shared the URL: If the person posts links, updates status or shares tweets once in a year, then the chances are the person does not know about the trends going on in the market. Whereas, a regular updater, who shares links daily and spends a lot of time in the social networks is assumed to know a lot about what’s going on. So, the links of the person who is more active are more likely to be prioritized than that of the person who is not.
- How active are the people he’s linked to: This is another thing that search engines seriously consider while prioritizing the URLs shared by a person. If the person who shares the URLs is active, but his social circles that actually get to see the URLs are not active at all, then there is no use of shared URLs. Also, other thing that matters is how popular the other people in his circle are. The more popular the people in his circle, the more chance are of being URL a popular one. It makes easy for the search engines to take a decision while listing the results.
Apart from these two, some people even debate that the person who is sharing the URL, if uses the search engines more, the chances of his shared URLs being prioritized are more. (Facebook has Bing as a search engine and Google+ has Google) But this theory seems too illogical to be considered as true.
