My site contains a lot of gallery pages. These are auto-created all having the same title attribute. There can be upwards of 6 pages in each gallery. Typically, I will manually edit the meta and title tags on the first page and Google would list this in its index and consign the rest to the supplemental index.
I recently did an experiment with one gallery, where I gave each page a unique title (all related to the content). Results so far, are good in that I'm picking up on some long-tail search queries on additional pages.
I was wondering if I can extend this strategy and substitute synomyns. For example, the title attributes would look something like this:
Page 1: title synomyn1
Page 1: title category synomyn1
Page 2: title gallery
Page 3: title synomyn1 gallery
Page 4: title synomyn1 gallery - name1, name2
Page 5: synomyn1 gallery - title
Page 6: title synomyn2 gallery
Page 7: synomyn2 gallery - title - name1, name2
Page 8: title synomyn2
Page 9: title category synomyn2
synomyn2 does not appear anywhere in the text of my site.
synomyn1 is the primary keyword for which my site ranks. (currently at #3). I don't rank at all for synomyn2 or "category synomyn2". Occasionally, I will rank very prominently for 'title synomyn2' if inlinking sites have used this as anchor text.
The Google adwords tool tells me that synomyn2 gets 4 times more queries than synomyn1 but I don't think Google recognises them as being synomyns. Google normally associates synomyn2 with a different niche than the one I'm involved in, but essentially, they are the same thing and there are sites out there offering the exact same thing as mine ranking very well for "category synomyn2".
Can anybody tell me if I'm likely to encounter problems targeting the synomyns. Will Google perceive what I am doing as over-optimisation?
