I am creating a niche web directory. Each category has a quality text and then about 1000 sites listed. My primary goal is to get Google traffic for each category intro. Only on 1st page of each category is text with first 30 sites populated, on the next pages there are only list of sites as pagination goes.
I am not sure what would be a proper way for pagination. Each first page category is unique, but next pages could be very similar because the same sites belong to different categories. Do you think using canonical tag would be acceptable in this case?
