In order for your website to solidify top rankings within the major search engines, you need to work towards developing a solid backlink campaign. The reason why backlinks are such a critical component in a successful search engine marketing strategy is due to the way that engines like Google place value on your site. Google measures your websites overall relevancy based on who is linking to you. It's a way for them to quickly evaluate your website and to connect it with a specific niche market. Backlinks also count as votes for your website, and the more votes you have, the higher ranking you'll receive - plus, developing a solid backlink campaign can help you rank for some remarkably competitive keywords that you otherwise might not be able to secure. Plus, when you work towards developing a targeted backlink campaign, your website will not only gain higher positioning, but it will appear more frequently. The highest quality traffic comes from the major search engines.
