Not guidance or advice, but I did try it once. A four figure book rank promptly dropped to digits longer than my telephone number.
Just to make sure I understand, are you saying the following?
- originally each of the 7 fields contained one word each
- this was changed to multiple words i.e. phrases
- this change caused the book's rank to go from 4 digit to N digits where N > 4
p.s. I am wondering if there was anything else that changed that could have caused the change in rank.
Oh God, no. That's completely ass about face.
Originally, each box was filled with a long tail keyword. For example: Box 1 = murder in a Las Vegas toilet, Box 2 = kidnapping an American gangster dwarf, etc etc.
I changed that to fill each box with one word. For example: Box 1 = toilet, Box 2 = dwarf, Box 3 = gangster, etc etc.
This change is what caused the rank to plummet.
Reinstating the original 'long tail keywords' recovered the ranks.
Apologies for not making that clearer.
(For the avoidance of doubt, those aren't my keywords. Not that there's anything wrong with them, they probably work for someone ...)EDITED TO ADD: When I say 'plummet' I mean in a bad way. Like, the starting rank, with full boxes, was at 3,000. The single word in a box, dropped the rank to 100,000.
