Hi there...I've been running my own adwords account for a couple of years and really enjoy the work. So I thought I should go into business and set up on my own and create/manage adwords accounts for clients. So I thought I'd ask if any of you have done the same thing, and if so, do you have any tips? Can you direct me towards any helpful resources? And do I need to be Google certified before I start? Have you made any mistakes that others could avoid...and do you enjoy it?! Sorry about all the questions!

Any help would be really appreciated...

Its not complicated. You just should be able to satisfy your clients to use of your services instead of directly going to Google adwords

Most seo companies offer this type of service so I don't see the reason why you can't do it. It would be better to have an established site with some reputation before you step in big.

Thanks for your comments everyone...all very helpful indeed. I've got a few more questions which I'd appreciate some guidance on:

1) Is there an industry 'standard' pricing model...eg, $500/mth management fee for campaigns under $10k/mth...and 5% of spend for projects over $10k/mth?
2) How do you get around the issue of billing? Do you request your fee plus monthly campaign fee up front? Or take the risk and charge them at the end of the month with another 28 days to pay? (ouch!).
3) Quit interested in the rev share model...how does that work?

Many thanks in advance!

Hi Charlie:

Going back to your original question - Adwords allows your client to grant you administrative access - this will send you an e-mail - click on the link to say that you are the person that is seeking access to their adwords account - then your client accepts you and you are given administrative or any other type of acccess to their account.

There is another way to access it - don't know that much about it - it is called MCC (My Client Center). This can manage multiple accounts.
