In our research with what we have done for ourselves and our clients, there is a definite co-relation between content greater than 1000 words and better rankings. In fact, we are finding amazing ranking jumps when you have content over 3,000 words, about 12 original images (images not found anywhere else online), 1 H1 (not keyword stuffed), 12 sub-headlines (H2), 12 relevant internal links, 6 relevant external links and 1 bullet list. I know it sounds like a lot of work and a Big Mac recipe, but this does work.
On one specific project, one of the SEOs on my team was brought in during the wireframe stage. The entire product team held SEO-specific meetings every week to go over specific recommendations, taking them very seriously, and leaning on every word our team said. We were thrilled. We were hailing their efforts, promising big wins for the relaunch, and even hyping up the launch and it’s projected SEO results in the company SEO newsletter.
Expertise and authoritativeness of a site increases its quality. Be sure that content on your site is created or edited by people with expertise in the topic. For example, providing expert or experienced sources can help users understand articles’ expertise. Representing well-established consensus in pages on scientific topics is a good practice if such consensus exists.
