Hello everyone, I operate a website called Icy Veins (www.icy-veins.com), which gives gaming advice for World of Warcraft and Hearthstone, two titles from Blizzard Entertainment. Up until recently, we had articles for both games on the main subdomain (www.icy-veins.com), without a directory structure. The articles for World of Warcraft ended in -wow and those for Hearthstone ended in -hearthstone and that was it. We are planning to cover more games from Blizzard entertainment soon, so we hired a SEO consultant to figure out whether we should use directories (www.icy-veins.com/wow/, www.icy-veins.com/hearthstone/, etc.) or subdomains (www.icy-veins.com, wow.icy-veins.com, hearthstone.icy-veins.com). For a number of reason, the consultant was adamant that subdomains was the way to go. So, I implemented subdomains and I have 301-redirects from all the old URLs to the new ones, and after 2 weeks, the amount of search traffic we get has been slowly decreasing, as the new URLs were getting index. Now, we are getting about 20%-25% less search traffic. For example, the week before the subdomains went live we received 900,000 visits from search engines (11-17 May). This week, we only received 700,000 visits. All our new URLs are indexed, but they rank slightly lower than the old URLs used to, so I was wondering if this was something that was to be expected and that will improve in time or if I should just go for subdomains. Thank you in advance.
