My site has been devastated by the Panda or unknown reasons so I need to think outside the box.
I distribute industrial products with average brand recognition. I only have about 5 competitors selling this same brand. My other brand competitors are billion dollar companies that pay a lot for PPC and have sites with 10 times the product offering.
Since my brand recognition is not as important as the function.I'm thinking about changing the part numbers to reflect function. This will affect about 1/5of the parts ( about 500 out of 3,000 parts) . My concern is will ranking be hurt or helped by changing these parts with these strong keywords in front of the part for such a high % of the site. The strong keywords cost $10 for a chance at a $200 sale with repeat business.
Example: Current part is: 10-10 Black Plastic; which is a Big Red Truck with my brand part # as 10-10 and comes in different colors of plastic. . Keyword is Big Red Truck. I would like to put my manufactures brand in the description. My same brand competitors sell 10,000 parts and my logic is that if I have the brand in 1/5 of my parts ranking would be improved because of the % of brand per the site versus my same brand competitors..
So I would change the part # to : **Brand 10-10-Black Plastic Big Red Truck **
In conversation I would state the part as:
Brand: 18 characters, Part #: 8, Material:12, Keyword: 27
If the keyword should be first I could change to: K,B P,M. Which is recommended?
