Backlinks are links from other websites back to your own. They’re sometimes referred to as “trackbacks”. Backlinks have a huge impact on your website’s search rankings. Lots of backlinks from high-ranking websites can greatly improve your search engine results, especially if those links use keywords in their anchor text.
It is important to have backlinks from qualitysites, and those backlinks should be relevant. For example, if you have a website featuring dancing penguins, and you are creating links from other niche sites about juggling polar bears, these links will be of no use.
The end goal should be to get links from authoritative and relevant sites.
