if your want to put H1 tag more than one time so it is not good for SEO put H1, H2, H3 this type of tag not H1 tag more than 1time on same page
i think also the h1 should be uses only 1 times, like in a good letter and the structure is so much better
You can use more than one H1 tag but it could be harm more than help. Overdoing on some element such as <b> <h1> <h2> could lead your page to be identical some weird pattern. If you have to used more H tag really, I would recommend use H2 H3 H4 instead of only H1 to be safe.
Using it in coding is allowed and can be done, but should not be done because this could confuse the Search engine crawlers regarding the core concept and center point of your website and this may harm your site ranking on the keyword you will be using in their.
There will be only one name for a chapter..Not twice..H1 is used as the main heading.So use it once only.As per the requirement only arrange the heading tags.. Like we write a simple letter or essays.h1 to h6 are the tags used in seo based content writing..use it accordingly..
I think one H1 Tag is more then enough on a web page as far the optimization of the website is concern.........
Will it make sense to put more than one H1 in your HP if you are a news provider with many headlines???
You Can Use Heading Tag, But only h1, h2 & h3 these 3tags are beneficial in seo other TAGS are you can use but you didn't get much more benefit from that tag's.
Matt Cutts said in a video that you can add more than 1 h1 in the same page when it is necessary but remember not to overdo it. Here is the video: http://www.youtube.com/watch?v=GIn5qJKU8VM
There should be only one h1 tag on a single web page. Using more than one h1 tag on the same page is not accepted by Google and may treated as spamming.
