I used to buy a lot from TF in the past without looking at the actual code first. Big mistake! Almost all of them are claiming that themes are 'SEO optimized' - big bullshit. Let me break it down a bit. For this ex. i'll take a new theme released on 23th May called Square. * there are a lot of elements but for this thread i will talk about 1 main issue H1 tag You all know that H1 tag is the most important heading element within your page. This 'SEO optimized' theme is using H1 to wrap up the logo. We don't need that! The logo is not that important to put it inside a heading tag. A simple div with an image tag should be enough. The post title This is where it suppose to be the H1 but instead we have the H4 tag, same as for single post title. We want the title of the post to be highlighted, not the logo + if we see 'SEO optimized' we might think (at least I do) there is also schema.org implemented - not talking about this right now. Why is that so important? For most of you maybe this 'little' flaw is not a big deal, but we keep talking about the importance of the kwds in the title, description and so on and we skip this simple check. I'm not saying it's a big factor in ur ranking efforts but surely is one of the many - keeping your keywords in the H1 tag. I found a lot of other mistakes inside these themes in terms of SEO and we can talk about them for many hours, but this one i found that is the most important. PS. This is not a rule, not all themes are like this one, although a big % of them are having this issue.
