After soaking up some of the knowledge & experience on the forum, you diligently set to work on starting your day-job-busting IM career.
You apply what you've learned about exploring niche's and keyword research, spend hours pounding Wordtracker and Google's Keyword Tool, generating keywords lists, checking the 'competition', and finally settled on that 'gold nugget' you found: 4400 searches per month, not too much 'competition', and a Page 1 SERP that looks achievable.
You set up a Wordpress blog on your Hostgator account, write 10 pages of good, original, unique content along with Adsense or a high-gravity Clickbank product.
You've learned you need backlinks to break into that Page 1 SERP, so you start submitting articles to Ezinearticles and Goarticles, buy a WSO of places to get high-PR backlinks, download Onlywire and start posting to Social Bookmarking sites, Digg'ing your pages, etc.
Then you sit back and wait. Shortly after your site gets indexed, you find yourself at #22 and start to get excited.
A few days later, you're off the radar, but you've heard about the "Google Dance", so you submit some more articles, do more backlinks & SB submissions, and wait.
Finally, FINALLY, the day comes when you've done it - Not only are you on the first page, you're #6!
You start checking your stats. Not much happening, but you figure, it's only just gotten there.
The next day, not much.
A few weeks later, and it dawns on you that you aren't going to see more than a handful of visitors. Period.
First, unless you run an Adwords campaign targeting your chosen keyword/phrase with a highest bid and big enough daily budget to show impressions for every search, you have no firm, reliable way to know if that "4400" number is accurate.
It came from Google? So what. At best it's close. As often as not, it isn't even terribly close.
And did that number show for "Broad Match"? That doesn't apply to you. "Exact Match" is what you want.
Next, did you do a "reality check" on Google's number? Use Wordtracker's free tool and SEOBook's free tool. Are they all in the same ballpark at least?
Ok, now lets do the math:
4400 searches per month equals approximately 150 searches per day.
Of that, the top listing gets the largest percent, and the top 3 get between 2/3 and 3/4.
That leaves between 37 and 50 searches per day divided among the remaining top 7.
And with each drop, the percentage decreases.
Realistically, even if you divide whats left evenly among the remaining top 7, you're talking about 7 searches per day each.
Keep in mind as well that depending on the type of search query, the top spot may get as much as 75% of the clicks.
If you want much in the way of organic search traffic, you want to be targeting a reasonably high total daily search volume, like a few relatively high volume keywords, or many lower-volume keywords,
Or, you need to get to the Top 3 listings,
Or, you need to systematize your efforts, and multiply them with many sites.
