Backlink 101
What is Backlink According to Wikipedia?
Backlinks (or back-links [UK]) are incoming links to a website or web page. Inbound links were originally important (prior to the emergence of search engines) as a primary means of web navigation; today their significance lies in search engine optimization (SEO). The number of backlinks is one indication of the popularity or importance of that website or page (though other measures, such as PageRank, are likely to be more important). Outside of SEO, the backlinks of a webpage may be of significant personal, cultural or semantic interest: they indicate who is paying attention to that page.
In Simple English
A backlink is a link from another Website pointing to your Website. Backlinks show search engines how important your site is. “Backlinks are also known as incoming links, inbound links, inlinks, and inward links.” – Wikipedia
The Formula
More Backlinks = Better Search Engine Ranking
Do I Need It?
Yes. It is one of the most important factors if you are going after a successful SEO.
Of course, there are even more things than this to consider when putting together a good seo campaign, but these are the basics of backlink building.
