Hello, I have some awareness of how to use H1, H2 and H3.
H1 only once per page as the main page heading.
H2's should be subheadings, H3's are sub-sub headings of the and so on. 
This structure gives hierarchy and opportunities to use additional keywords in an order of priority. I can clearly understand how this would work in an article but what about other content on the page such as global/frequently repeated elements like sidebars and footers? I see sites - and in particular, I have examed SEO focused sites - that use  H3, H4 and H5 in these instances seemingly giving themselves scope to use at least H2 tags as part of the page content and break out of the structure hierarchy when dealing with sidebars and footers. I suppose this could signal theses headings are sections of the page that are less relevant than the main article content but that is just an assumption. I don't know what is correct.

Hi folks, My homepage has 3 identical H1 tags due to the fact that I have had to create individual hero images (with headings) for desktop, tablet and mobile. I couldn't get my theme to display the layout in exactly the way I wanted on each device without doing a specific hero image and tag for each device type. Does this have a major impact on my SEO? Thanks,
Mike.

I recently attended a webinar by ETNA Interactive on local search SEO. The presenter recommended including the name of your town in the title of the blog to increase local search SEO. Is this OK? Ive always been concerned that it is such an obvious attempt to rank locally that Google would consider it "spammy" ? black hat, "sketchy" or otherwise manipulative. Have the rules changed? Is it OK to do? Brooke

If I hide H1 tag (title on the homepage) with CSS, how Google handle with my site?

We are using templates that load the same header for every page. I'd like to just include a different title tag in the "body" template of each page. If I was to do this, does it affect SEO at all?

Should I have the same H1 tag in my header through out my entire site? Or is this considered to be  self canalization for my main keywords. For example right now I have an H1 tag with my main targeted keywords on every page on my site, even if the pages content doesn't necessarily match the keywords in the H1 tag.

Typically H1 tags are reserved for page headings, i.e. on a blog post the blog post title is very often the pages H1, or top-level heading as the W3C puts it. On the SEOmoz home page they currently have "SEO Software." as their H1 tag, which seems perfectly reasonable and to me fits the W3C criteria. However, what if the primary keyword for SEOmoz was "seo community" so they decided to wrap just those two words in the sentence that follows on their home page and maintain the existing style of the words "seo community" with CSS. (see attachment) Are there any arguments against doing that? Would Google be able to detect this? If so, would Google care? I do believe the overall importance of the H1 tag has lessened to a degree, however I still believe they are valuable to an extent and would love to hear anyone's thoughts. 7NZcD.png

Meaning heading tags (H1, H2, H3, etc) are a critical part of good on-page optimisation. Fair enough. It helps humans and bots make sense of a page's content. 3 questions regarding implementation of heading tags: Should heading tags appear in sequence in the HTML code. I.e. H1 first, then H2 lower down, etc.? Can the page contain more than one H1 tag? Can the page contain multiple H2, H3, H4 tags?
