OK< a bit of an example, my site has a lot of photos - and photos is a good search term, but I had used the term gallery often in titles, <h1>s links etc and this diluted the match power of 'photos' while boosting 'gallery' - unwanted / no use.

In short, what I am saying is that one cant rank so well for both gallery and photos as one or the other - so look carefully, decide and focus ...
