Optimize Pages, Not Sites
This might be a simple tip for many people, but it could be an eye opener for some. When we think of SEO (search engine optimization) we often talk about how to optimize your site. Certainly many elements of SEO are on a site basis, for example proper use of heading tags (h1, h2, h3, etc) in a template.
However optimizing actual content should happen on a page-by-page basis. After all, when you search Google pages are returned in the results, not a list of site homepages. People sometimes make the mistake of trying to optimize each page of their site for the same single keyword, or same groups of keywords.
While I’m not going to give away the farm with this tip, think about optimizing pages, not sites, for SEO. Think of a phrase you want to optimize for, create the page, and move on to a new phrase and a new page. Don’t worry about optimizing your entire site for each of those phrases.
