This algorithm contains ~200 signals to get sites render. And jet, we may only guess, which those could be. For sure we know a few things. Seo can be narrowed down into 2 groups. Onsite and Offsite seo. Onsite seo uses title, descriptions, keyword density, site structure, content, img alt, anchor title, strong etc.... to get better ranking for targeted key terms. Ofsite seo uses, inbound links, outbound links, social media, article submission, link submission, conversions, etc... to list your site at a top-notch position.

Good post by ARTidas. As he says there are 2 main parts, onsite and offsite SEO. On site needs to have specific keywords included (which you should have doen research for). It needs to have it to a certain keyword saturation percentage (some say between 1 and 3%). You need to include the keyword in your headers (ideally between h1, h2 and h3 tags), use metatages, images with teh right alt text etc Off site basically means backlinks which include such things as * Reaching out to other sites in the niche * Article directories * Press releases * Link wheels * Forum signatures * Social book marking and much more. Whilst content is king, in SEO and for readability, the power of backlinks shouldn't be overlooked.
