Thread: importance of h2 tags

hi all

I have more than one hundred articles on a site, each page is given in the text.
I have highlighted in bold the words seem important to me, and I mostly put the h1 tags to all titles of my pages, but the text did not really architecture ...
Does it have a real impact on my position if I made by paragraphs titled h2 tags in the text?

For example, my page on Venus (h1):
h2: orbit
h2: atmospheric composition
h2: its surface relief

Google would position it better and built a page? Is it worth me re-enter one by one the pages of my site? (knowing that there is anyway no tags h3)

thank you for your opinion

Do you mean you're thinking of using the H2 tag several times on one page?
