Many internet marketers find themselves afflicted with what is called "information overload".
They have so many ideas to consider and so much information to look through that they become overwhelmed, and end up doing nothing.
If you are in this position, you need to just step back and think for a moment.
Many of the techniques which are given for free on websites and in free ebooks are old and tired, and many of them were flawed in the first place.
Anything which claims fantastic results for little or no work is likely to just be a false promise made to get you to join an unworkable scheme.
The classic example of this is the old traffic exchanges where you surf the pages of other people.
You create your landing page, and then you surf other peoples' landing pages, knowing that a percentage of the people who are surfing the exchange will see your offer.
It sounds plausible at first, until you realize that everyone has joined the program for the same purpose as you - to get THEIR offer seen! No-one is looking to join anyone else's program, or to buy something from you! The key to effective marketing is to get your offer in front of the people who will be interested in it.
There are techniques such as keyword research which you can use to make sure that your paid advertising is reaching the people you need to reach, and also that you are not just advertising to people searching for free information.
The same research can be used to make sure that your article and press release promotions are targeting the correct market.
Narrow down your internet marketing research to techniques which target the correct market, and you will start to see results.
