My hubs w since last few months generating traffic of 1500/2000 per day which all of sudden traffic falls down to a great extent and . It was learnt that it was due to some technical changes made by hubpages. It was also mentioned in couple of weeks the hubs would gain normal traffic as before but no good has done so far. I was also intending to change my username, but it was denied by hubpages that it is not a good as it would result in change of web address which is already in record of search engines like google. Now, why they have made the changes without prior discussion with members?
