I make revenues from Adsense at a very high click-through rate. I experience high click-through rates with AdSense without resorting to questionable tactics like tricking site users with photos (the AdSense trick and tip dujour).

So my perspective is from one who has made decent income from Adsense to fund aspects of his business like advertising seminars -- and outsourcing to his virtual assistants. Yes, AdSense is a legitimate and significant revenue source. However evaluate AdSense with some type of balance.

But there are obvious and not so obvious times not to use Adsense ads on your sites. Let's list - examine - and explain them below.

1. On Sales or Mini-sites

This is a no-brainer. If you are trying to sell a particular product that is important to your bottomline, for more details visit to www.instant-adsense-dollars.com you don't want AdSense ads distracting your customers from either joining your email list, or hindering your site's online sales process.

However I do see hybrid sites that are mini-sites or full scale eCommerce sites, with AdSense at the bottom of their pages. This might not be so bad since only 1% - 15% of your site visitors will either buy from you or fill out a form.

2. SEO Business Sites

If your livelihood depends on search engine optimization or marketing for a living you might want to think twice about displaying AdSense Ads on your site. I can tell you this from personal experience. I once was on top of MSN for search engine marketing in my local area. I concentrated on my local area because I found people felt more comfortable hiring an eCommerce consultant locally.

I analyzed all the top ranking sites in MSN and noticed the only difference between me and the other top ranking sites was I had Google AdSense ads on my site. Someone at MSN felt that my AdSense ads, and perhaps to a less extent, for more details visit to www.google-atm-machine.com my book on SEO, was getting a free ride in the MSN search engine database.

Many of the leading SEO gurus have sites that have been banned from the top listings by the search engines. It seems the more visible you become, the more of a target your sites are to the search engine auditors.

Think about it, how long will MSN and Yahoo! sit back and watch SEO driven websites use their search indexes to fund Google? Did you know SEO in MSN and Yahoo(!) --- is much easier to obtain.

Therefore optimized sites are creating an ad sales wealth transfer from MSN and Yahoo into the pockets of Google! It won't be long before Yahoo! and MSN begin to devalue ranking on AdSense sites in their databases -- if not outright ban them.

If you are in the search engine business stay search engine neutral, or create multiple sites for different search engines.

3. When AdSense Becomes Your Only Business Model

When you become so myopic in your thinking that you build a business solely on AdSense revenue -- think again my friend. Why build a business solely on the largess of Google?

I don't know if your realize it or not, but the sites making the real big AdSense money usually have a following that doesn't depend on the search engines. Internet mavens like Chris Pirillo or Joel Comm have been on the Internet a while and have followings for their websites. Therefore they can consistently make six figures with AdSense.

These content powerhouses are an asset to Google and not the other way around. But do you think Google is going to sit back and watch just anybody make big bucks off of their top rankings?

If you do a search on most keywords you will notice many of the top ranking sites are news sites, .gov sites, or .org sites these days. The only exception is in industries where these sites don't really exist like eCommerce industries (clothing, shopping, etc.).

No doubt in most industries you will notice a conspicuous scarity of AdSense sites in the top rankings. In other words don't bet your future fortunes on AdSense.

An IPO based on projections of AdSense revenue isn't in the future for the average eBusiness. Think of Google AdSense as supplemental income. Building a business solely on AdSense revenue isn't just silly -- it's just plain stupid.
