Ranking dropped after changing title tag

[ForumOne]

I recently changed my company's site homepage title tag to make it start with our target keyword. The page was originally at page #7 or #8 and dropped to page #17 directly after I changed the page title. Is this normal? Is it's a temporary drop or should I change it back to the previous title.

We would never know that.

That "Ranking strengh" is the sum of all the ranking factors google uses (I may guess over 500) that only Google knows and never will reveal.
Moz tries to analyze and is a nice metric, I will nor rely completely on it, because it only uses on page  data, that is just a part of what google analyzes.

Hope I've clarified, if don't just ask again

Thanks Gaston. Is the "ranking strength" using the similar calculation method as how Moz calculate the "Page Optimization Score?"

Hi there,

Yeap, that's perfectly normal and there is no way to ensure that you will rank the same or higher position, its likely but no one can guarantee that.
After a change like that, Google tries to re calculate the "ranking strengh" your page has for the selected keyword.
Give it a little more time, a few weeks, 3 or 4. Then evaluate if the impact was the correct.

Hope it helps.
Best luck.
GR.
