Ive been making changes to sites now based on various sources of information. The objective of the changes is to acheive a better rank.
The changes (done separately - then wait for cache update) and monitored over time (about 4 weeks) have been made on 7 domains of mine.
The changes are split into 3 types.
1) I changed some sites to add the keywords to them inside various HTML tags which I was informed was helpful. So for example I added an address tag with my keywords in it (just an example).
2) I added certain words (not my pink widget words) to my pages which I was advised google required so that it could place my site in the correct "category" - a "Selling" site that is - for pink widget. Rather than an "information" site for pink widget.
3) I added my pink widget keywords to *new* anchor text on my index page which links to existing (and indexed) subpages containing the keywords.
All my changes are cached now - the index page of each site which is where all the changes took place across all the domains are all pr1 to pr3 (just to note)
I do believe that the above changes ARE ranking factors (please please please please correct me if you think im wrong).
The sites are all ranking between position 4 and 80 (so not under any penalties I can see).
Other info - no affiliate links on the sites, pure oscommerce + hand written index page (which im tweaking).
The main point is - non of the sites have moved in rank - AT ALL!
I feel like im flogging a dead horse. Ive spent weeks reading and reading and got nowhere.
Has google not yet factored in my changes maybe?
Cheers - any advice appreciated.
