One thing is we should do the basics that have worked for the last 12-13 years.

First worry about on own page. Meta tags, content, and such.

Second, get incoming links, buy asking, adding our sites to other resource sites, giving people a reason to want to share our links, giveaways, writing articles, press releases, etc.

Third, update our sites regularly.

Fourth, adjust our sites as needed.

Fifth, get a new site, and repeat.

Except for the above, for the most part, the basics have worked since the first concept of SEO, before it was even called SEO.
