Question regarding the "right" (if there's such a thing) keyword density in product description content.
I need to rewrite the description text for about 100 widgets produced by our company - how many keywords can/should be included?
In our industry, widgets can be only 2 types, and made of only 5 basic materials, with 3 being very common.
Typical searches for our type of product include:
"material" + "widget"
"type" + "widget"
"material" + "type" + "widget"
"designer" + "widget"
Here's an example (manufacturer's name changed to Example, common Google keywords for our industry are in bold, unique/protected names capitalized, all other in lowercase):
Graceful form and enduring blah blah blah of the highest-grade material1, the Model Line of type 1 widget from Example creates a design statement etc etc etc.
Model Line's blend of high-grade material1 and secondary material makes it the perfect companion for your particular situation.
Like all other Example material 1 type 1 widgets, the Model Line features fine Foreign-Country engineering along with stunning design.
With a powerful feature1, electronic feature2, easy maintenance, feature3, the exclusive Example Feature4, and many other attractive features, the Model Line models are the perfect choice for those who demand the best in technology and style.
Two things make the Model Line Type 1 Widget stand out from the already-unique selection of Example Widgets: patented "Brand Name" Feature 5's for certain special benefit, and included Feature 6 for the perfect finishing touch.
Is this too many keywords? Too few? Should they be grouped closer, or spread farther apart? The same structure will be followed on all other product pages (overview - affirmation - commonality - specifics - highlights), and I would like to work out a guideline for writing this content, keeping a balance between SEO and style.
Also, since this content is only visible if the user clicks on the control header, does Google consider it part of the page, or a separate page (as far as the calculation of keyword-weight VS amount-of-total-content goes?)
Thanks in advance!
