We noticed a few weeks ago that rankings for the phrase
Charity Collection Buckets
Were bouncing between this page
http://www.carefundraisingsupplies.co.uk/fundraising-products/Charity-Collection-Buckets
Rank 16
to this page
http://www.carefundraisingsupplies.co.uk/fundraising-products/fundraising-supplies
Rank 85
So we de-SEO'd the second page and added more content to the first page.
This seemed to lock Google onto the first page at 16, but it then started to slowly slide downwards. We have made a few more on page text tweaks, tried to reduce keywords density all to no avail.
Even though overall this site has a better DA and MOZ profile than those ranked 1 and 2 for the phrase, we just cannot seem to get it moving in the right direction.
We are just about to apply some quality links to see if that helps. But we are wondering if we are missing something at a technical level, like category structure, Canonicalisation, 301 redirects or something else.
Any thoughts?
