It’s very important that you understand what can boost your website’s ranking and what is just a waste of time. There are lots of techniques in Offpage-SEO that used to work in the past but are regarded as spam today and therefore completely useless.
One proven method to get on top of search results is to build backlinks on high PR websites. How can you do this? You can ask them to place your website link on the domain or any subdomain if you have valuable content to share, but this will generally not work well and it is time consuming to send hundreds or even thousands of emails to moderators.
Or you can create profiles on discussion forums and add your links. Thus you can get on top of search engines with your keywords.
