I am interested to develop back links from WIKIPedia site for my website html5 showcase and css menu , Can any one tell how to develop link from wiki.
first off, you didn't need to link to your websites (with anchors) here. as far as getting backlinks from Wikipedia is concerned, they have got very tough to get backlinks from now. Plus the links are nofollow. I think following thread of DP would give you some help http://forums.digitalpoint.com/showthread.php?t=2154898
Getting the backlinks from wikipedia is so easy (if you have high quality references to the concerned article in the wikipedia). You can simply add the links in the reference section of wikipedia article (but as HelloM said, the links in the wikipedia or nofollow, so you will not get any PR benfit with these links). What all you can get is, referral traffic.
If your product or content has history reference without marketing material , so you will get listed in wikipedia.
