If you should use an internet search engine as an example, then none except Google are going to do. Google is the most widely used search engine and there is no wonder why that could be. It has spiders and bots that crawl the internet and look to index websites and do you know of. These crawlers not only crawl the content of each site, regular crawl the backlinks.

They invalidate low quality sites and in the event backlink is connected having a site tend not to like, then you simply won't get looked at.
