The term "conversion rate" is simply ratio of people that visit your site versus number of people that visit your site and buy something from your site. If you have 100 people visit your site daily and 4 people buy from you, essentially your daily conversion rate is 4%.

That's obviously an unqualified number because you don't have all information about those visitors for that day.

There is no real standard definition that everyone adheres to and agrees upon and there is no governing body that says online marketers must define "conversion rate" same way.

The "conversion rate" metric can take into consideration any of or more of following:

* A 1st time visitor to site versus 1st time visitor who buys your main product on 1st visit.

* A visitor who reviews your site but doesn't buy on first visit but does buy on a subsequent visit.

* A visitor who doesn't buy but joins your list and buys later.

* A visitor who doesn't buy your main product but joins your list and buys another product of yours.

* A visitor who buys a product from you not associated with main site which is where they were originally referred.

* A visitor who buys your main product in a bundle that includes other products visitor is interested in.

*And so on...

Take above scenarios and add in fact that most of time source of traffic isn't given, and you can easily get an 'ambiguous at best' definition of what "conversion rate" means.

FFA sites are places where anyone can post a short ad with a link, as long as they agree to accept emails from site owner. Some of most popular sites are

(1)ffanet.com (2)myebiz.com (3)prolinks.com (4)kiosk.com (5)ffamailblaster.com

At first thought this seems like a remarkable way to advertise. But, there are major problems here.

First off, only way for advertisement to work is for people to visit FFA site where it is posted. But only people it seems that visit these sites are those that post an ad. To make matters worse, 99% of posts are done now through autosubmiters. So who actually sees your ad? Absolutely no one.

You may have received emails from FFA site owners of claiming that advertising via an FFA is worthless unless you actually own site. Their flawed reasoning (which I will explain shortly) is that as owner, you get to post your own ads on site, and better yet, collect email addresses of everyone posting. Moreover, you receive commissions on anyone signing up to purchase an FFA site of their own.

But wait! It gets better. The same people will claim that when submitting your ad, create a separate email account to store large number of autoresponder messages you will receive and other advertisements. So, if you don't want your primary email account to fill up, create a secondary account and simply delete emails as they come in.
