I have been managing PPC accounts for a while now. Some are small and some have big budgets. Managing PPC sometimes though is like a cat and mouse play. Very time consuming if you want good results. Not to mention Google’s very vague explanations on the factors of a good PPC campaign.
Just recently though, one of my favorite SEO/SEM blogs posted a very good view on Google’s Ad Auction factors as they call it. Here are the links to their posts:
Organic campaigns take a lot of time. Some results vary, but on the average, you will see the results in at least 3 months, maybe more or maybe less. PPC on the other hand is quick. A few hours after setting up and you will already see the results.
The thing with PPC though is that, when you stop paying, everything stops. With organic campaigns, after you get everything stabilized, the end-result is long lasting.
If you learn to you use both techniques though, you’ll get more.
