How to Pick A Niche

Confused about what direction to go? Where to start? Here's a quick breakdown based on content from Yaro Starak:

First,

1. Do Keyword research to find out how many searches are going on
• Goal: Over 1000 searches a day 
2. Check  Google search results to see how much competition there is
   
   • Goal: Less than 10,000 competing pages

What is "Quality Content" according to Google Panda Update?

On Feb. 24, 2011 Google began instituting a series of major changes to their algorithms with the goal of more effectively distinguishing "high quality" from "low quality" sites in effort to return the most relevant, and helpful results to their Google users.  Now, more than ever, if an affiliate doesn't add value beyond what the supplier adds, they can expect a lowered page ranking.   Effectively, this can be seen as a call to action for affiliates to strengthen their work, provide quality, and use their own authentic voice.

Which Niche is Best?

Yes, dating, loving, fitness, making money, coupons and weightloss are extremely popular, but that doesn't necessarily mean they're the money makers for the start-up niche blogger.  So, question:

Which niches have the greatest chances of eBook or product sales?
I shall investigate.  

VigLink. Have you used it?

Just discovered VigLink and installed on a few of my blogs today...  Although i have no other prior knowledge of them, I'm sure hoping it will be turn out well.  With attempting to blog professionally comes the need to generate a revenue stream, am am hoping this will prove to be a valuable tool for that purpose.     I need to learn more!     

Would love to hear  from anyone who's used it!

So, I installed the Viglink in several blogs, but... nothing seems to be happening (at any of them)!?  Maybe I did something wrong?  No idea.  Will have to investigate...
