Computing ROI for pay-per-click can be a bit tricky. Since most sites receive “free” traffic resulting from SEO efforts, it’s important to try and ferret out what percentage of sales are resulting from pay-per-click and what percentage are resulting from your other SEO efforts.

Choosing which sites and search terms to allocate advertising dollars to can also be somewhat daunting. Rapid changes in per-click charges can also be challenging to manage well. If your bid is #1 and our competitors lower their bids, you may be left paying a higher price than necessary to maintain top positioning. This is webmaster’s equivalent of throwing money down drain. Unless you plan to sit by your computer watching per-click charges on an hourly basis, some type of pay-per-click management is, in my opinion, an absolute necessity.

In running a successful pay-per-click campaign, there are also questions to be answered about whether to try for top positioning or settle for some lesser spot, and which pay-per-click ads pull best.

While I have learned “never to say never”, I am not presently using pay-per-click for any of my websites. Though I have used it in past and may resort to it again, my website is doing better than ever without it. Pay-per-click is just one more thing to manage, and, if not managed well, can become a financial drain in a hurry. I’m a pretty busy person, and probably a tightwad as well. As a result, pay-per-click isn’t part of my current marketing arsenal.

That doesn’t mean, however, that it might not be right for your site. Do some testing, study it out, and consider “cons” described in this article. In words of an old adage, “if something is worth doing at all, it is worth doing well.” This is especially true for things that cost money. My advice is to keep that thought firmly in mind whenever you open your webmaster wallet.

3) Internet Based Network Marketing

I've heard many people say that Internet and network marketing are a match made in heaven. In my opinion, though, almost 90% of people get it wrong when it comes to Internet based network marketing. People in this business usually think they're talking about network marketing, but in reality they are talking about affiliate marketing.

They try to make Internet do all work. They hide behind their computers and pretend everything's going great. They focus on selling more and more every month. They have systems that are so complicated only they can understand it. Well, that doesn't sound like network marketing to me!

Internet based network marketing is simple if you understand it, and are willing to put in effort. The role of Internet here is only to get you names and contact details of people you can talk to, after which YOU, not a computer, has to build a relationship with these people and help them to start their own business.

For this simple purpose, it is not necessary for you to have a high-tech system and pretend that your auto responder is building relationships for you. It's not going to work. The key is to have simple systems that are duplicable, something you can teach to all those people you have built a relationship with. For this purpose I use NetMarkPro at http://www.netmarkpro.net/globalmillionaire and teach my own affiliates to use it too.

E-book authors, no matter what they say, have no obligation to teach you their "Secret Strategies to Become a Millionaire” of any variations to that. The reason is simple; why tell you absolute truth when you'll end up as their competitor? No one wants more competitors, right?

Internet based network marketing is very much opposite of that. You HAVE to tell people EVERYTHING you know or your business will never take off. For this reason alone, I always recommend that if you're new to online world, you need to first join an Internet based network marketing business at least to learn. Rest assured, no one will be selling you half-baked truths when their success ultimately depends on yours.

No matter which model you choose, make sure you understand basics, and stop listening to and buying things that are not applicable to your business. Information overload can stop you before you even get started.
