although the back links from wiki are nofollow but google will consider the back links are quite high. It is really hard to get back links from wiki.
wikipedia is nofollow, it is not passing any PR juice to your site However, it is still good because it can generate targeted traffic to your site and also help in crawling
After the massive de indexation of public blog networks, wiki backlinks has been another great source for backlinks. Most of us know that link diversity is really important even before the panda update. So if you could make wiki links, why not? High pr or no pr, do follow or no follow, it still counts as backlinks. But don't make too many variations when spinning the article. And I suggest to write quality articles [with value] when making articles for SEO.
It depends on what you mean by Wiki backlinks. There are more wikis out there than Wikipedia. I assume you mean wikis in general. It all depends on the Wiki, there's no clear-cut answer. Only that link-diversity is good from quality sources. So, if it's a good wiki and you get a good in content backlink then sure, it's good.
Any nofollow back link i.e wikipedia or other high page rank but nofollow doest not give you page rank but would give you organic and direct traffic as well.
They usually get removed. But regardless of being nofollow or not, nofollow links DO STILL COUNT, don't listen to people who tell you otherwise!
Just to clarify about no follow backlinks. The best practice in SEO is to have link diversity, to diversify anchor texts as well and trying to make the backlinks as natural as possible. So if all backlinks we have on our site are all do follow, so it is obviously not natural that a site only contains all do follow backlinks. Hope this helps to people that are confused if no follow has a value or not.
dear but it is mostly very much useful to get traffic on current news or events; for example if someone happen recently and you update the wiki pages about it with a link on your site that link would give you the traffic
