You could do a lot of damage to your site trying to "fix" things that didn't need any fixing.
Even if you do no real damage, a struggling small business could spend "many" thousands of dollars trying to correct things that simply did'nt need correcting to begin with.
When we noticed a algo-filter of sorts last year, the minute we moved to a dedicated server and spent 60-80 hours of time trying to correct [insert your best guess here], the costs starting piling up.
In the end, we did get our situation corrected... but I can't say with any degree of certainty what it was that helped. Or, if none of the changes made a difference and Google simply made another algo change!
I think 140-150 of those 200 ranking factors revolve around confusion! :-)
