Welcome to the Q&A Forum

Hi Mikel, I'd concur with your SEO consultant's view The subdomain set up (i.e. http://nero.hispazone.com) is sub-optimal as the search engines essentially see subdomains as individual sites - so any strength or authority you have from hispazone.com is not passed to nero.hispazone.com. I think you're saying that you've been recommended to go down the subfolder route - i.e. hispazone.com/nero - if so I think this is a better solution for you as any strength or authority you have from hispazone.com is passed to hispazone.com/nero. The subdomain route can of course work, but in order to rank well you'd need to build links to each subdomain as if they were separate sites - which is of course pretty resource intensive. I hope this helps, Hannah

Research google panda. Many sites are in the same situation a you. Time + cleanup usually somewhat helps, according to rumors
