Write content for visitors and not for search engines. 2) Keep updating your content, add some useful articles, news or any other content on regular basis. 3) Develop links slowly and naturally, build links only from closely related to your niche. Just plan your actions and follow the same. 4) Use anchor text diversification for links, use main keywords, brand name and general text for links.
