SEO negatively affecting Adwords? Spotty tracking past 2 days?

[flhu]

My company's old website had less-than-mediocre SEO and an Adwords campaign with a dismal 1.2% adwords conversion rate. August 1st, I launched a new website and immediately the adwords conversion rate went to between 3.0 and 3.5%. We were suddenly getting over three times the number of conversions every day.

Over the course of the month I noticed increased ranking of the site in all the search engines. Not so good with the more generic terms, but for product names, their manufacturers, part numbers, sometimes product categories, in the top 20, if not the top 10, if not the top - even above the manufacturers.

Two days ago the Adwords conversion rate dropped from 4.3% the previous day to 0.6%, even though the new increase in overall conversions remained steady, and is now in the third day of less than 1% adword conversions. Same amount of clicks, and cost consistant with the weekly cycle.

I still allow the possiblity that the google tracking code might be messed up, but why would it still register conversions at all? Maybe spotty reporting back to Google the past couple of days? I have validated the code on the site; it works fine, but I have noticed more conversion referers possibly being Adsense partners and Sponsored Results than the campaign summery for the day seems to report.


Has anyone noticed new, improved SEO as having an affect on Adwords conversion rates? I mean you would think that 1000 people coming to your site is 1000 people, no matter if they clicked the Sponsored or Organic listing, right?
Or Has anyone noticed a sudden drop in Adwords conversion rates in the past 2 days?

Is it just me?

WHat a minute you redesigned your website and you dont think that will effect AdWords and/or organic rankings?

No, I redesigned the website August 1st; SEO got better rankings, and started to appear organically on the first page for many keywords.
More people trusted the website.

Conversions (leads) from adwords more than doubled. Cost per conversion was cut in half.
Conversions overall tripled.
This happened almost overnight and lasted all through August.

We even had an amazing Labor Day weekend, which, when you consider the website is B2B, was completely unexpected.

THE PROBLEM:
Then, after a month of this great improvement, a few days ago, for two days, even though conversions over-all remained steady, Adwords campaign manager showed conversions dropped to unprecedented new lows. I could trace the referers of the leads, and it appeared that some more were coming from Sponsored search results than Adwords campaign manager was showing.

When one of the reporting measures you have to try to convince your boss that you deserve a raise is that you reduced the average cost per lead from $75 to $35, a couple days were each lead appears to cost $400, you know it's not correct, you don't know why and don't see a way to fix it, I think would unnerve you, too.

Well, the second days conversions just suddenly appeared at once towards the end of the day. The one day is still out of whack, but I can live with it now that everything appears to be working fine.
