H1 tags are pretty important as they are meant to be the header of what the entire pages is about. Every page should have 1 and only 1 H1 tag and should definitely contain your most targeted keyword.

It's OK to have multiple H2, H3, H4 tags though. Although they don't count as much as an H1 does, it's still important to include your keywords in these tags when applicable too. Make sure that you're not "keyword stuffing" either.

So to answer your question, yes, if you don't have H1 tags on a page, and then add them in with the appropriate keywords, they will def help your on page optimization!

Hope that helps!

You should be using hyphens.

Google treats underscores as word joiners, while it treats hyphens as word separators. In other words the hyphen is like having a space between the words and tells Google and that they should be treated as two separate words.

Because H1 tags are meant be explain what the page is about, it's good practice to have them at the top of the page. If you absolutely want to have a friendlier title, make it an H2 that is styled to be bigger than your H1, and style an H2 for that main header of your page. Does that make sense?

dofollow links pass "SEO Juice".

nofollow links do not pass "SEO Juice".

If your curious as to whether or not a particular blog allows for dofollow links, you can view the source code of the webpage using any common web browser. Find the link in question, and look to see if it includes "rel=nofollow". If that tag doesn't exist, then the link is dofollow.

MissVe,

you can change your permalinks. You just need to set up 301 redirects from the old permalinks to the new. This not only forwards users to the new location but tells google that you've moved the page as well. This is the best way to handle your situation!

Hope that helps!
