Inviting someone through Adwords should give them all the control they need to optimise a campaign e.g. change bids, add/delete keywords, add/amend/delete ad text etc. Don't hand out the original username and password. That way you are protected, and if necessary you can withdraw access easily.
What kind of contract to you have with this consultant? Make sure you're protecting your data and account.
what is "adwords limited access"?
I would definitely not recommend ever giving out your full login details. A consultant should be able to perform any necessary tasks after being invited to the account through the access link, or by adding your account to their My Client Center.
gut instinct my man, gut instinct
if it dont feel right, don't do it
i'm a consultant and use an MCC to access my clients accounts, there's absolutely no need to share your own credentials. if you think it's been compromised, change your password right away.
through my MCC, basically, i can see everything my clients have setup except their credit card number(s). so, in my mind, when a consultant is asking for your password, i think they're asking if they can have your credit card number(s). yahoo and MSN system shortcomings aside for a second, there's absolutely no reason why your adwords consultant would need this info - especially if you were able in the past to setup your billing settings with G.
i'd look for another consultant, not cuz i'm paranoid about what G ads they'd spend money on, but because i see no truth to their statement about why they need this greater access - so they seem ignorant of how the system works - not a good sign absent a solid, plausible explanation.
The other option is to make them use the AdWords editor.
The editor has sharing options where you can have them make the changes in the editor, and then review the changes before they go live.
Thanks everyone for your insight. I added this project in one of those freelance website and the guy has 12 good reviews from other users. So i trust him a bit. But giving out such info just seems too much.
Sorry to come in to this a bit late. I would strongly recommend you do not give out your Google login and password to anyone.
A consultant can get all of the information they need to offer advice regarding your adwords advertising by accessing your account through their 'My Client Center' (MCC). It still means a leap of faith on your part - they can read all of your data and change bids etc. They cannot however change your login and password so you can ban them from accessing your account at any time. They cannot ever stop you from accessing the account.
If they do not know about MCC etc. point them to:
We made a small flash movie about this to explain to our potential clients what we feel is the correct way to offer external consultants access to your adwords account:
(I'm sorry I don't know how to access only part of the movie - but the bit of interest is "2. What does SAYU need for a health Check" - it doesn't have to be SAYU, it could be "What does any company need to offer advice about your account" :-))
