With time, SEO has evolved and grown by manifold. The old SEO techniques have become obsolete and are replaced by new ones. SEO is classified into two categories; On-page and Off-page. For your site to rank higher, it is imperative that your site is properly optimized and maintains the keyword density of your targeted keyword. If your website’s On-page SEO is not done properly, then even your offsite SEO won’t bring in the desired results.
