For one of the search phrases that my site has ranked well for several years is now being dominated by a single company who has several sites. Currently, they have 8 out of 10 page one results for one search phrase by using multiple domains that offer the same service. The sites are not duplicates, but are extremely similar.
Now, if you include my other top 2 search phrases along with this one, they have 20 out of 30 page one results. These three search phrases are the top search phrases in our industry.
I've reported it to Google, and hopefully they will take action, but since they are not *exactly* duplicating these sites I have my concerns. If Google does not take action, it will only encourage others to do the same thing.
Any advice on what else I can do besides reporting it to Google? One might say, just focus on your site and work on its rankings. Well, even if we were number one, a majority of the traffic would still go to this network of sites devaluing our service to our customers.
