The requirements for onsite SEO don’t change nearly as often, but it is still important to look at the things that are likely to be most impactful going forward:
If a site has high quality content that provides value to the visitor, their rankings will only benefit from changes at Google or the other search engines.
While it is not 100% clear whether or not having a mobile version of a site will impact SEO directly at this point, it is still important as part of providing a good user experience.
A mobile version will almost certainly have an impact on SEO in the future, if it doesn’t already.
Strategic guest posting is quickly becoming one of the most powerful ways to not only get high quality back links, but also get direct, targeted traffic.
Finding blogs in a related niche, and reaching out to them for guest posting opportunities is an excellent strategy.
Once an article has been published and indexed on a page, it can then be syndicated out to other people’s sites in related niches, with a back link to the original page.
All sites should have a related page on Facebook, Twitter, Google+ and LinkedIn. Most sites should also have an account with Pinterest and other photo sharing sites.
Building up a following on social media sites is almost as important as improving where the site comes up in the SERPs.
Taking a written article and turning it into a video slide show can provide a good boost to SEO as well as bring in some good traffic from YouTube and other video sharing sites.
Whenever trying to figure out a good SEO strategy, one only needs to think about what will provide the visitor to the site with the best possible experience.
