I'm currently doing some article marketing for my software, but I'm a bit nervous about how my idea is going to work out SEO wise.
I'm thinking about writing 1-5 articlet on invoicing for a specific small business type. (this could be pool cleaners, carpenters, retailers etc). these articles should cover some of the most basic invoicing principles that are more or less in common in every business.
When I have written these articles I plan on rewriting them for a bunch of different businesses (this way 5 articles times 100 types of business = 500 articles)
What I am very worried about though is that these articles would recieve some sort of penalty in the SEO department since the contents would be very similar but targeted very specific audiences.
Would I be digging my own grave by going down this route?
Should I invest more time/money in writing very unique content for the various types of business (it is difficult to come up with 500 variances of how to write a proper invoice)
Any suggestion is much appreciated
