Backlinks, also known as incoming links, inbound links, inlinks, and inward links, are incoming links to a website or web page. For example, this link points to Google and is therefore an inbound link for Google. Some people would argue that link building (inbound links) hold the most weight when search engines determine a website’s ranking. This is true to a certain extent, but in truth both backlinking and good quality, regularly updated content should be the driving force of any successful SEO campaign.
Backlinks can almost be seen as currency. A website with many inbound links will naturally rank better in search engines than ones with not so many backlinks.
Many years ago when search engines where just finding their footings and SEO was pretty much unheard of, the way search engines would rank a website was very much down to how many backlinks a site had. Now the whole game has changed and there are hundreds of factors that determine a website’s search engine position, especially with Google’s new Penguin and Panda updates. Although good quality, high authority backlinks from relevant websites still do help with determining a website’s search engine position, therefore care must be taken when building links to your site.
