Impressions down over 50% from last year

Any insight appreciated

[tv33]

I have a niche site that I advertise for with Adwords. There are only two keywords and it's a medical-related topic. This time last year, when I first started the site, I was getting around 6000 impressions per day in the search network. Things were successful and continued until June where I saw a dramatic loss of impressions. In july things got even worse and now in August I'm only getting around 1300 impressions per day.

My Ads run 100% of the time according to google (and my own personal test).

It just seems that not nearly as many people are searching the terms this year v. last year. Is it normal/possible that the majority of the people with the condition (medical) have already looked into it and that new sufferers simply can't supply the demand?

Does anyone have any insight here? I'm starting to just think maybe the idea has simply run its course (unfortunately).

tv33,

I am going to assume that your keyword terms are broad match. Over the course of the last year, we have made some revisions to the way your broad match keywords are expanded to similar terms. We have become more 'strict' with what we consider similar and you have consequently seen a decrease in impressions.

I would recommend making use of the keyword tool to try and identify some potential keyword terms that could be added to your account. Not all of the suggested terms will be appropriate, but by adding some of the recommendations to your account as keywords, you may be able to regain some of the impressions you seem to have lost.

You're not imagining it. We shut off all AW campaigns a few weeks ago and haven't noticed much difference in how many *quality* leads our web site is capturing.

Google is not what is once was in terms of quality of clicks or in many industries the number of searches. Big websites like travelocity, amazon, webmd have spent millions of dollars branding their domain names. Now a lot of people when they are looking for travel info don't go to Google and search 'Hawaiin Vacation' they just type expedia.com directly and bypass search engines completely. I'm not saying everyone does this obviously, but a lot more people than 2 years. Portal websites are cutting down search impressions in many categories B2C and B2B.
