In reviewing my AdWords and lead stats for September, compared to July, I am seeing results that don't seem to be seasonal, because I looked at the same periods last year and did not see the same trends:

Impressions are down by 30% or more, depending on market areas.
Average CTR is higher by 25%.
Average Conversion rate is up by 35%.
Average cost per conversion is down by 40%.
Lead quality is much better. More full names, more good phone numbers, fewer bogus email addresses.

And I didn't do anything to my ads, bids, monthly budget or landing pages.

Questions:
Is anyone else seeing this trend?
Do you think it is related to the market conditions: Fewer "lookie-lous" because they are put off by the market?
Are other agents / brokerages shutting down their AdWords campaigns due to revenue issues, so those uf us who are left are getting more/better leads?
