Off-Page Optimization
Off-page search engine optimization is not just about links. It goes deeper than that. All the measures that can be taken outside of the actual website in order to improve its position in search rankings is what referred to as "Off-Page Optimization". These are measures that help create as many high-quality backlinks (incoming links) as possible.
Many people associate off-page SEO with link building, but it goes beyond that. Many activities that don’t result in a standard link on other sites are important for off-page optimization.
On-page search engine optimization happens within the site, while off-page SEO happens outside the site. If you write a guest post for another blog or leave a comment, you’re doing off-page site promotion.
The longer you wait to take action, the more you fall behind.
