its not that simple but you need to have some real information which needs by general public . just create an account and you can edit any page or create a page which not exist
httx://en.wikipedia.org/wiki/Wikipedia:Starting_an_article I hope this will erase your all confusion.
To create a page on wiki you simply need to register there and then you will be able to create your won page; but do not make duplicate content and most importantly you can add links on the reference region; but in the body you can hardly use buisiness links. They allow non profite or non buisiness links like any university or any official sites. I do not know details you beter try first.
perhaps a full page does, but what about just a link in the citations section? Â would that have any weight even if it is no follow?Â
You just can't make an account and start making thigs. Also, you need an account just to monitor your works there. You can work without one. So, first you need to know what improvements have to be done there. Unlike other things, editing Wikipedia pages is relatively easier. Do small things first. Start making small corrections in articles you skip over in daily use. Correct minor errors like spelling mistakes and grammatical errors. Learn the basics. There are articles that show how you can edit, how you can add hyperlinks etc. in wiki language. Now, add copyright-free photos etc. Now, when you get the hang of it... just don't jump over making articles on everything. Don't make your profile page there. Ha ha. When you find that an article on something you know is missing, click the link 'make an article' on the 'No Results' page. Grow slowly, and it will be great. Your small pages will automatically grow.
You can't just promote a business that no one would want to read about, leave that to your blogs and article directories. Leave Wikipedia alone from all of the marketing campaigns.
Wikipedia already has a lot of articles. Before creating an article, you should search to check that there is no suitable article that already exists. If an article on the topic you want to create is there, but you think people are likely to look for it under some different name or spelling, learn how to add a redirect with that name; adding needed redirects is a good way to help Wikipedia too.
At the very beginning just create an account there. Then look for similar articles, if they are, you can use them as a supporting information for your article. It's also important to check whether your information is not much commercial and you should search also for supporting articles outside wikipedia (their sources also should be trustworthy). If you don't know how to create the article itself there are special articles on wikipedia about that or you can just click "edit" at the similar article and copy necessary tags there. That's all work))) It's not so difficult as it seems to be
If no proper articles already available or the subject has enough depth for an article of its own then you can start a new article.
