CTR is a decent measure to troubleshoot your ad.But more often than not, your ad copy is not resonating with the pain point of your ideal seller, your ad is too generally targeted, or the ad is just bad.

Otherwise, it's just something else to maintain and troubleshoot (and explain to guests how to use).

No managing contractors or wasting time troubleshooting "easy problems". 

Do you have time available to snake a toilet or troubleshoot a sprinkler timer?

Not sure what your particular property situation is, but I'm happy to troubleshoot if you're having zoning issues!

Furthermore, some cable companies will insist on using their own run of their own wiring to the actual cable box, partly because they don't want to trouble shoot something not working which may include a piece of wire not put in by them that may or may not work, but also they want to make sure they know how many splits you have, to how many TV sets, as in some locales they can charge you more if you split the signals and use cheap Chinese knock off converters and descramblers.

You can send more peaces for same amount, if you negotiate these two items better.If it still doesn't work, trouble shoot your campaign.

Part of this problem is that I reside out of state in California and had to basically run this renovation and troubleshoot problems with little help on the ground in Scottsdale (yikes what a nightmare) to deal with.We were finally able to obtain the license to operate as a care home in February (got delayed by some water plumbing maintenance issues).
