I think its clear from title. Do they help or its a waste of time even you have quality content? Thanks
Yup! it won't help you in terms of link value but you do get traffic if its a popular keyword/term in wiki.
Yeah, that basically answers it. The link itself wont help you from it but the actual traffic from it can and will, assuming your page is worth anything to the visitors. A few years ago, I had a Wikipedia article linking to a page on one of my sites and I got considerable traffic through it. Didn't make any money off it or anything, but the traffic was there.
Well, first of all.. not all search engines cares about the nofollow tag. And second, it might bring you quality wikipedia users.
in addition to what the people above are saying, other sites scrape the mighty Wiki - like answers.com - and they don't enforce the nofollow attribute on links, so you can get some value there. err, don't go spamming wikipedia though, that would be bad.
wikipedia links will NOT help your seo or pr because of nofollow but they will only send targeted visitors to your sites
Having a link in wikipedia not only gets you visitors, but it also recognizes you as reputable source of information. This will help build up your reputation with users.
Most wikipedia discussions about links revolve around PR but do you guys think it helps getting a site better indexed? Spiders crawl wiki all day long ... any visits in your log files from the bots?
When I had an external link on a very small, low traffic Wikipedia page, I got about 600 uniques a month from it. Definitely worth the effort in my opinion, but the Wikipedia editors are VERY picky about the sites added.
I get about 600 visitors through five or six Wiki pages that I'm listed on. All bar one of them I added the link myself. I've not tracked to see how well they do, though, but it's all traffic.
