Encourage incoming links. Google prioritises sites that have a lot of incoming links, especially from other trustworthy sites. Encourage clients, friends, family members, partners, suppliers, industry mavens and friendly fellow bloggers to link to your site. The more incoming links you have the higher your site will rank. But beware SEO snake oil salesmen who try to trick Google with spammy links from low-reputation sites. Some links can actually damage your SEO.
Remember when you used to rely solely on search engines for traffic? Remember when you worked on SEO and lived and died by your placement in Google? Were you #1? Assured success. Well, okay, maybe not assured. Success only came if the keywords were relevant to your site users, but it was the only real roadmap to generating site traffic and revenue.
