I have keyword files (with a top layer focus KW) and need a 150 word description for each focus keyword (and meta description & title also).
Unfortunately I don't know of any tools that build out meta keywords and descriptions. However, I'm a little confused. Can you give an example of what you'd like to generate based on your keyword files?
For example, given a specific page with content on that page, I'm familiar with tools that will generate ideal keywords to target ranking for, based on how much traffic keywords get, and the best anchor text to rank for such keywords. However, I'm not familiar with doing it the other way around. How can you generate a page title and page description based on keywords? Wouldn't you need to create content about that keyword as well on the page?
