Different H1 tag on every page

Good Pm,

I really was wondering since I think its very important if I should have different h1 tags on every page on 1 website?

ex. my page is Dogjumping.com

Keywords on h tags:
My Main: <h1> Dogs walking people</h1>
1.Page <h1> Dogs on Fire </h1>
2.Page <h1> Dogs without banana </h1>

Or should I only have 1 <h1>keyword</h1> on the whole website? and use <h2> for the 1.Page and 2.Page keywords


Thanks for the time and effort!

Most SE are using H1 for short description of a page. So, using H1 differently for every page is better than only one H1 for whole site. This can be applied to meta description for each page.

Sorry its my fault, im kinda having a hard time in describing my question:

On main page i have the keywords dogs on fire so my h1 on the main page would be "dogs on fire" too... And on my 2nd page on the website my keywords for the topic is drunk cats.. So I should use "drunk cats" on my second page right?


Because usually people use one keyword for thier whole website and paste it even h1 key tags on every single page...

i dont know if youre familiar with html 5, i have read a lot about it and i think <h1> tag is used mostly on main article titles, so if you have 3 articles in you home page is best to use h1 description for each of them. html 5 is going to pay to much attention to h1.

Thanks for the really usefull reply http://www.blackhatworld.com/blackhat-seo/members/30161-bonehead.html but I still got a few questions:

1)

Is it preffered to go after only 1 Keyphrase on one page instead of 2?
Ex. what I am doing right now..

Titel: Watchdogs outside
1x h1 tag: Watchdogs outside
path: http://www.mypage.co/watchdogs-outside.html
meta keywords: Watchdogs outside, dogs watching out

Or is it too much ?

-------------------

2) What do you mean with duplicate page nullifies my effort:

I mean I have as keyphrase optimzed for "online huskys now"
Could I make a second page which is optimzed for "huskys online now"?

aswell as "cats and dogs online" and make another page "cats and dogs online now"

would it be seen by google a dupliacate?
