Estimating Keyword Market Size

I used Keyword Planner: Search Volume and found out that the Average Monthly Searches for my number #1 broad keyword is 27,100 month.

It takes me 1450 impressions to get a conversion. So that seems to me to mean that every month I have a pool of 27,100/1450 = 18 people who I can possibly convert. Is this reasoning sound?

If I am converting 2 people a month with my current budget does it stand to reason that if I spend 9x as much I will convert 18 people a month? Is it reasonable to assume that my spending will have a linear relationship to my conversions? Or is this a bell-shaped curve situation with diminished returns after a certain spend point?

Also, of the 27,100 searches a month for my keyword, am I really being seen by all of those searches even if I am in AdWords position #1? I have heard that if 100% of searchers view the 1st organic result, 50% of searchers view the 1st position AdWords ad on the right side, 25% view the second ad, then it drops significantly from there. So is my AdWords ad in the #1 position only being seen by half of the 27,100 searches? What about the AdWords ads above the organic search results?

If even one of these questions can be answered I would greatly appreciate it. I'm always down to write a testimonial for anyone too.

Thanks,

-Chase

    "If" you're #1 in search results you could expect 42% of the total traffic. So you could have 11340 visitors. You said your conversion rate was 1/1450 so you should have 11340/1450 conversions - so about 8.

    But 1/1450 seems like pretty low conversion rate. I'm just getting back into IM, but iirc I would usually get around a 1/200 conversion rate.

    Theoretically, the more impressions you get the more conversions you will get.

    Of course, there are always other factors at play, but in theory the conversion % is the conversion %. More impressions = more conversions. Fewer impressions = fewer conversions.

    You should concentrate on conversions per click as opposed to conversions per impression. Because, even if your impressions are limited, your clicks can be improved. So, you'll get more clicks and, likely, more conversions.

    You can see what percentage of the time your ad is served in your stats. I forget what they call it exactly. Impression share, maybe?
