Does Lack of CTR Reduce Organic Impressions

[numbers]

I have a business model that works off Impressions and not CTR.
Obviously impressions on a search engine normally lead to CTR and the landing page does the conversion.

But what if I can convert a sale directly on the search engine results page without the client clicking the actual search result. Therefore the CTR is heavily reduced.

Does a reduced CTR effect your rank on the search results?

I know that in PPC the CTR is an important factor for relevancy, thus reducing your PPC costs. Result is you pay more per click to get position 1-3.

But does it matter for organic results ?

I am currently testing the model and do have pages in rank 1-3 that generate approximately 3 times the number of conversion to the CTR (unique sales).

I would also like to know if there is a way to measure the numbr of Impressions a page gets with their search rank, webmaster tools does have it but it seems to be a rounded to the nearest 10,000 figure.

All contributions on this welcome, Thank You.

It is believed that bounce rate and ctr do play as ranking factors - how much is yet to be determined

but without CTR you get no bounce rate, would that not cancel it out ?

They compare your stats with other sites and if your site is getting less ctr i can see that hurting you

The most honest answer is that we simply don't know.

There is some speculation that CTR and/or bounce-back rates and search refinement rates factor into the rankings. No one has proved either, but both seem to make sense.

If I were Google, I would use CTR as one factor among many, but only judge against results for similar positions in similar results. For example, the CTR on simple questions is likely to be low across the board, so I wouldn't hold that against someone.

With all of that said, I am currently responsible for a number of sites that actively try to convert people directly from SERPs. We haven't noticed any downside to it because we satisfy their query when they do click with more information and they don't click on other results either. As I said, it makes sense. Google would compare apples to apples if they had any sense.
