EMD stands for "Exact Match Domain" and is employed by some recent systems and methods although this knowledge is not really new.
Here some observations, i am sure some other might have some tips also.
-> "Exact Match" does not always need to be an exact match as it seems.
You can easily check this for yourself, and it doesn't matter whether the keyword is some product name (like "cbpredators") or say a word like "animals".
Type animals in google and you will see that google will highlight in bold this in the domain names, but they are actually not *exact*. In fact it considers "animal" too since sites are coming up for "animals" which use that word in the singular form in the domain.
I also observed occasionally how SYNONYMS seem to have the same weight.
Type yeast infection cure in Google and you will see it comes up with sites where it actualy high-lights yeast + infection + treatment
According to those observations it is likely that an EMD (exact match domain) does actually NOT need to be an exact match, but there is some flexibility in your choice of domains.
If you want to have an "EMD" but the domains are taken you can try plural/singular and synonyms and you are likely to rank as well as with a real EMD.
