It is really hard to get a backlink from Wikipedia to your sites unless it is very popular or your company is very reach and have Wikipedia page, I can not say about it will effect your search rank or not. But you can get a wikipedia backlink in less then 30 seconds Here is the link https://en.m.wikipedia.org/w/index.php?title=Special:ZeroRatedMobileAccess&from=india&to=http://www.india.dj/ Just change The URL, Also you can change From and Language of the page the EN to ES , HR, RU etc..
I don't understand what is, or rather was, the hype around Wikipedia. It's a nofollow link, it has barely any impact. Sure, it's nice to have it, but you won't see much results out of it.
It is not about hype... The goal is to get trusted sites to link back to you... Is 1 Wiki link going to make you rich? No! 1 link from wiki starts to show a sign of trust... and if you have everything else right... google trust is your key to success... Will just 1 trust link do it? (no, its just a starting point...) If you are going to do the wiki dance, then be prepared to have a decent budget... If we start out with similar sites at the same time, We both have 20 high quality articles, however, if I have 10,20,50, 100 wiki links, then who do you think will get more trust, and love from google? me or you? 1 wiki link is worth 100 low quality backlinks. If you have a low/med keyword, then one wiki backlink maybe just enough to start pushing keywords upwards.... Other then desperate people concerned about SEO would be concerned if it is no-follow, do-follow, so what... your end goal should be anchor/link diversity... Google will analyze all of your backlinks, and if you do not have any quality/trust links, then you are most likely to move up the latter, at least not very fast anyways, so if you want to move up the latter faster then the avg joe site, then start getting backlinks from trusted sites, and this would include Wikipedia.
Also, the idea many-a-year ago, was that if you were linked to by Wikipedia (rather an editor, into Wikipedia) you also get lots and lots of do-follow links, do you know how? Because, lots of places all across the interwebs "MIRROR" the Wikipedia pages and not all of them are no-follow. But like dscurlock said, trust is very important. All three of my websites: johninjapan, okinawahdr and hdrjapan got loads of links from Wikipedia, and I didn't create those links. My websites had unique content "in English" about Japan, ao it was very useful. All I had to do was syndicate Mainichi News (Japan newspaper) and they had terrible support in English, so I helped keep their articles alive by hosting them. I don't even own those domains and their links are still in Wikipedia from 8-10 years ago.
Unless you are related some how with wikipedia, then you pretty much have to buy your way on today. You can find wiki link sellers on source-market, however, there is no guarantee it will not be deleted. getting some links from wiki would start showing that trust factor, merely because google highly trust wikipedia, and trust starts following down hill.... you have a better chance if your site is non-commercial, non-profit.....
I believe wikipedia is more on building online reputation and brand, and not just for link building. I have a content on wikipedia but getting my content approved is not as easy as you think.
