Everything You Need to Know About the NoFollow Tag

Building quality links is becoming harder and harder to do. This is because Google is trying to weed out artificial links. You have to keep in mind that Google's business objective is to connect people with the best and most relevant information for the searchers particular search term.
Many sites now have a NOFOLLOW tag, which basically causes all outbound links to be EXCLUDED when Google bots crawl the site. In other words, if there is a link pointing to your site, from a nofollow site, it will not be recognized as a link in Google.
There is a lot of speculation, and I get a lot of questions about whether links from NOFOLLOW sources have any value. I think about it like this. Even if Google does not recognize or count a NoFollow link in its crawl, other search engine powerhouses such as, Yahoo and Bing, do. Even if all search engines stopped counting NoFollow links in their crawls, these links could still get significant traffic from the particular website linking to you.
I do not spend a significant amount of time getting NOFOLLOW links, but if an opportunity presents itself to add a link that may get me some traffic I do it. I spend more of my time trying to find some PR ranked sites and well as some.edu or.gov sites to add my link.
If you are wondering how to know whether a site is NoFollow or now, the easiest way is to get the SEO add-on for Firefox. It will highlight all NOFOLLOW links in red so you can immediately see where you can potentially get links from.
