Hello everyone. We did lot of work in our daily life on our sites for high rank and for google top. But our work not give us good results as we think,this is because we made back links from not good sites. We get thousands of backlinks through our manual work, if we give links from higher sites then it gives us good results. we generate thousands of backlinks but all links not gives us good rank it is because we not select good sites for backlinks. So i suggest all SEO expert and site owners, first collect good sites for backlinks and then work on sites if you have 500 to 1000 strong backlinks then then through strong backlinks sites comes on top and give you more real traffic.
