I started an Adwords campaign for a particular service our company offers which ran over Christmas. Having reviewed it this week, the ads haven't performed quite as well as we predicted (actually at all).
Checking the Auction Insights report doesn't show our competitors (as expected) but a list of companies that offer a service which is a homonym of our main keyword. It is (hopefully) very obvious from our landing page the service we offer (B2B, nothing remotely shady). This would make sense why the bounce rate and average time on page for Adwords traffic is so poor (especially when compared to organic traffic).
For most of our keywords the quality score, ad relevance and landing page experience are low/below average.
I added negative keywords (including for the unwanted homonyn) at the start of the campaign.
Could Google have misunderstood my content? (I appreciate that the opposite is quite possibly true and that my ad copy and landing page really are just poor.)
