One of the main keywords to my site did a bad ranking on google, so I tried to fix it.
It ranked on page 12-15 on a search – tested on a weekly basis. First off I tried to add the keyword into more noticeable places on the site, both inside the h1 tag, but also in text. That did not make any improvement at all.
Then I noticed that almost every result above had the keyword searched for in the title tag, so I put the word up there, and guess what? Now my site is at page 7 on that keyword… So, I conclude, title tag is very important for SEO.
