Tip 1 out of 5: Be an Expert

You at least want it to be professional, and experts should have "something to do with it". Experience, proof of income beats everything in internet marketing, so be sure there is tons of it. If you are sersious it's of course suggested to choose the most professional tips you can get.

Tip 2 out of 5: Proof

Proof... Oh man, this is a biggie for anyone who is a bit seasoned in the game, but when you are a "newbie" it's not easy to recognize "truth" from "fiction". Some people make outrageous income claims which nobody who has been around would believe... But when you are starting out, it's not uncommon to fall for these types of "emotional triggers", I know I did when I was new.

Tip 3 out of 5: Credibility

Who is this person? Can you google him/her and find multiple sites? Can you find hundreds or thousands of articles written by the same author? Does he or she have multiple websites with similar proof, products? Are they running a blog or newsletter? This is usually a good indication that the person is serious in the biz and it increases credibility.

Another part of credibility is testimonials. Does the website you are visiting have solid testimonials from solid resources? Are they credible? Do they show Images? Audio? Or even video testimonials? If at least one or two of these are "true" then it is good indicator of a proven product, backed by a proven crowd.

Tip 4 out of 5: Overall Design

A professionally designed website with a header graphic that feels professional is a great sign of a solid website. You should reconsider if the site looks like it's created by a 10 year old.

Tip 5 out of 5: Other people are recommending the product.

This means that if you search for things like "review" or "testimonial" or "success story" on Google you find at least one or two website that have a solid review of the product. This is VERY common and should indicate a serious business owner who has gone great lengths to find affiliates and joint venture partners.
