So here is progress and details on how I did my keyword research.
I decided to not pay for any keyword tools. Felt that doing it manually at least for this first campaign will be a great exercise in getting into the buyers mindset than just downloading some long assed kw list. First thing I did was identify the big categories of people that would benefit from the product. So say, if I was promoting some all-purpose pet cleaner (random product cause a dog just walked past me) then the main groups this would help with or would search for it could be: owners of dogs, owners of dirty dogs, owners of dogs with flea problems, owners of dogs with dandruff problem, owners of furry dogs. After that, I just grabbed the free keyword list from Google for the particular categories to give me an idea on terms to bid on. After that its just a matter of packaging those keywords with the primary root with command phrases and descriptors.
My hope for doing this is that because this is an initial launch, I will be able to test a broad net of categories to find one which is converting and then maybe I can expand on that list even more. For example, ideally I will find that say owner of dogs with dandruff problems are generating disproportionate amount of conversions so I can really hone in big time into that category.
The current keyword list is standing at ~750 primarily 3-4 word lists. They are organized into 75 ad groups which seems like a lot but I know this niche makes money and I want to come into the market as targeted as possible.
Next step is to write up ad copy for all 75 groups. My goal is to get 2 ads per group that I can split test with right from the get go. So, I have the fun activity of getting a 150 ads written up this weekend. But all goes well I will be ready to go by this monday. Love how I thought I would be able to do all that I did within a few days when I started this journal. Goes to show the sheet amount of work needed to launch somewhat respectably.
P.S. I found a few facebook offers that are looking really interesting. I am going to run a few of them as a side project cause that looks like an interesting traffic source. Building up an image gallery right now for ads when I launch.
