Whether you did the campaign yourself AND whether you paid for it.
Now if you are going after really long tail and are looking to rank for a number of terms whats a good goal for you as to total traffic combined?
If you only go after 1-4 keywords in a campaign what number of searches per month is too low for you to purposely go after? Ranking top 3
100 searches a month
1,000 searches a month
10,0000 searches a month
NOTE: I DO NOT MEAN GOALS FOR A SITE OR AIMS. I mean a SEO campaign where you are optimizing a site for a certain set of keywords and building links before moving on to the next set of keywords etc.
Now obviously we would all WANT the higher numbers but whats the MINIMUM number you would declare as some meaningful success?
Hopefully I am explaining the question good enough (maybe not).
I know this varies widely due to monetization so feel free to include those variations. For example in one of my niche targets (high paying) its usually 50 visits a day on a newer site so my lowest level of success for that would be 1500 a month.
Since we all do SEO for traffic its an interesting discussion to hear others perspective. There is no right or wrong unless you don't think about traffic at all or don't do conversion calculations.
