Age of search engine crawlers:

From age old days where the search engine crawlers used to take up to a month to crawl a page and can take another 15 to 30 days to re-crawl the page things have changed a lot. Now search engine crawlers are the best compared to previous years. Lot has changed with search engine crawlers. Due to ever evolving algorithms and new features added to crawlers they tend to crawl a website much easier and faster than ever before.



Way back in 2001 search engine crawlers were not so sophisticated. Most of the crawlers including Googlebot take a lot of time to crawl a page and more time to refresh the data. It slowly evolved over the years and today we have Googlebot picking up pages of millions of websites in minutes sometimes in seconds. Features like RSS, XML feeds atom feeds help Google track blogs and other relevant sites and they crawl the pages as soon as the new pages are live on the blogs. It's not just blogs Google at times have capabilities to detect changes to a website and if a webpage is added search engines are good enough to detect the new page and crawl it.
I call this the age of Crawlers because they just amaze me with their speed and effectiveness. Imagine millions of WebPages are updated every day but Googlebot is able to detect and spider them immediately. I wonder what the future will be for search engines I don't see any more improvement to be made lets wait and see.
