Making Millions with Affiliate Marketing

I met with a guy yesterday who is the digitial advertising business and works for one of the TOP online conglomerates around.
He manages the digital advertising of some of the most expensive online ads and websites.
We discussed one of his clients.  He told me that this client nets around $500,000 a MONTH purely from affiliate marketing!!!
His client has no inventory, has no brick and mortar shop and nothing to sell. 
The way it works is:
He is an affiliate of other companies. 
For example: A company has a website that sells expensive jewelry.
An affiliate signs up with that company as an affiliate.
The affiliate invests money in paid advertising in the best positions on the web.
(This is the only expenditure of the affiliate)
Once the ad is clicked on, the customer is directed to the main website, in this case, the jewelry site.
If the customer decides to buy a product, a nice commission is sent to the affiliate.
There is a third party software that manages the amounts of clicks that are brought in through the affiliate's advertising.
So wise affiliates know 2 things:
1) Which e-commerce websites are the most in demand and pay highest affililate commissions.
2) Where to spend their money in advertising.

Mobile and Local Search Results

Mobile internet usage is skyrocketing globally.  Searches on mobile devices are often local results.
Your websites should be mobile compliant- a tip from Olivier Amar and independent marketing consultant at PointUp media. 
Additionally, every month you should list yourself onto different websites that keep you on top of local searches.  Examples of local sites are google, yahoo, bing, yelp, facebook, Better Business Bureau, citysearch.com, zagat.com.

Analytics and Competitive Analysis

Search Engine Marketing (SEM) is not just about organic or paid listings.  Even if you rank well for a keyword- you need to convert on that traffic - or else what good is it?  You can use analtyics tools to track the success of your online marketing, but also to pick up on what your customers are doing.
