If you’re a PPC agency, you do not want to be making this mistake. It can really tick off clients.
1. Let your tracking/redirect subdomain get indexed. This means that your “ppc clicks” may be random longtail crap clicks. Or else nasty competitors, breaking your analytics with fake traffic.
2. Carelessly run the subdomain off your main domain. In other words, tell the world (and clients’ competitors) that your clients have ‘hired guns’ running their campaigns. Motivate competitors to take this seriously, why don’t you?!
3. Call the subdomain something obvious. That way, people will be encouraged to try site:”track.*.com” searches, click all the links (throwing off your total clicks and CTR numbers) and find out who your various clients are.
The right way to do this and not anger folks is to make this look like one of hundreds of generic tracking URLs, such that a simple “site:” search won’t reveal them all. E.g. y.abc.campaign1.example.com .
Spotted: Twice this month, being done by two major agencies. Major means the type with flashy booths, full colour print ads and juicy speaking and writing engagements. The situation was their work for clients in some of the most competitive verticals in search marketing. What’s competitive? How about $15 – $23 estimated CPC for top 3 positions? (Per Google’s AdWords tool.)
Matter of fact: Make that a third firm – yours truly! That said, my subdomain wasn’t as obvious, the redirects weren’t for clients, and I’ve already edited the robots.txt .
That said, I’m not going to out either, because one agency’s founder scored karma points with my at SMX Advanced and I don’t need to pre-burn bridges with the others. Relationships matter!
My point: 1) You may want to double check this for your agency. 2) You heard it here first!
