Just thought I would post this in case any of you found it usefull. I origionally found this out looking into discrepency's i found on mnf and googles keyword tool. I would find results that made no sense, broad match less than exact match etc.
I've found that a lot of the time when it says something like 600000 results i will change my search settings to show 100 websites and loads of times there will only be say 4 pages, after that it will say results have been ommitted because they are very similar or the same would you like to repeat search with omitted results included? Usually when i click it to include the results it makes no difference to the results and i just get the same old message.
These omitted results, i take it i wouldn't have to worry about competing for them right?
Where do they come from? Why exactly are they omitted?
