If you are deciding which one of the internet marketing gurus to follow the first thing that I would advise is to sign up to their list. Narrow your choice down first to perhaps four or five of the internet marketing gurus that you are interested in but simply sign up to their mailing list and wait for the emails from the internet marketing gurus to flood in.
Now hopefully, the emails that you will receive will be full of helpful information without diving straight in to try and get you to make a purchase. On the other hand you may get some emails from the internet marketing gurus who don't really offer anything of any value apart from telling you to hit the buy button for the latest must have product.
These internet marketing gurus should be unsubscribed from at the first opportunity. They don't care about your success, only their profits. The internet marketing gurus who take the time to help you should be investigated further and when you have come to decision about which one of the internet marketing gurus to follow you should stick with them and not chop and change from one of the internet marketing gurus to another.
The type of internet marketing gurus that you have chosen to follow will be able to really help you as long as you realise that you will have to put the work in. The internet marketing gurus will be able to point you in the right direction but they certainly won't do the work for you.
