Hello, I'm currently working on a client project. They seem to have strange programming practices. The result is that they use an header tag (h1), along with an hyperlink, so the header tag is actually clickable, along with the content of a DIV including some text and an image. So, of course I know this is not a good practice, but Im wondering what is the impact on SEO? Will the header tag, still be considered as an header, or will it be considered as a link, or both (I guess not...)?
I'm actually testing what you're asking and I've seen some slight improvement on a competitive niche although my markup is different. I'm using h1 on the site title (clickable) and my header image (not within h1) is also clickable. Take a look at the markup of a Wordpress blog. Should give you an idea on what you would like to try. You might want to build a separate test site just to see its impact.
IMO, using <h> tags on important links is a good idea. it's like saying that this link is extra important than other links here.
Thats not a correct way to go about it. H1 tag is meant for your main headline. If you start using it on links or random keywords in you web page google will not like it at all. With that said I am not sure the effect on seo of having your main headline in <h1> tags and also being a link. Wordpress blogs use this practice and they rank good so my guess is that it has little to no effect. It might even be good.
Exactly. Use it in moderation. I did not mean to say put <h1> and <a> on all your keywords . That's just silly.
Hmmm i am beginner is SEO, but i ever heard about meta tag. Are <h1>..</h1. is meta tag? If yes, i hear that is good step to get good position in search engines
No, H1 is a heading element used to describe and introduce the content that immediately follows it in the section of the document (Web page) it in turn is contained in. If you really want to learn how the search engines treat HTML elements, the best place to start is by reading the HTML specification itself. Seriously.
According to my experience, having an h1 tag on top linking to a site and not a lot of other h tags on the same page, tells the search engines that the most important information regarding what the keyterms in the anchors in the link promise, is indeed on the page it links to.
