Hi, i have few videos on youtube and 2 of them, from same account are going down in pages... the videos are on page 5. I bought views from bigbuddy and they don't even moved... Yesterday i modified the title for exact keyword and some in description and jumped to page 6.
I also had a older account with a video on the same keyword page 2, yesterday i modified a little bit, now is page 5.

Please help me, both of them i modified with some extra tags from a first page video and title to look exactly the same as keyword. What im doing wrong ? Please please please help

Wait a few days, it will come back stronger.

you are expecting results way too soon.. Don't do much changes in short time, because you can't see the results of the original state..

Changing your title/description/keywords will take changes in 48 hours.

What I recommend you is to wait and see. Heck, in the meantime you can make a similar video with similar keywords on another channel.

but it's been 3 weeks since is page 5 and now 6 and on page 1 are videos 1 week old

Hmm... It's complicated! If you want more specific answer PM your keyword.
