First of all, i would like to thank you for visiting our main site.
These days SEO market is going from very bad days because of some bad seo people who want to make quick money and they made too. In very beginning of SEO we just have to concentrate on links and links but now things changes much.
After google last years(2012) updates like panda and penguin now we also need to take care of quality, content and other on-page elements too.
Many of webmaster are quit because there websites are penalized because of bad seo from google.
