In episode 339 of Semantic Mastery's weekly Hump Day Hangouts, one viewer asked about the estimated max number of mass pages allowed to avoid Google's red flag.
The exact question was:
Hi Guys, I hope you are all still well and safe (smile) . . . I have two quick questions I need your help with (smile) . . . . (1) I know you are not an advocate of creating “”Mass Page”” Local Lead Gen sites (smile) . . . . and I believe that Google now has the ability to see that 1000's of pages on a website were created simultaneously, and “”red flag”” it. Is that correct, and if so, what in your estimation is the maximum number of website pages you can use software to create at the same time to avoid a Google “”red flag””? . . . .
