1. What are your objectives maintaining this site? Do you need more visits to acomplish these objectives? Do you need more subscribers?
2. Are you using subscriptions to get more visitors? Are you using it right? What’s your conversion average between subscribers/reads/visits? Does your content have any relevance to the subscribers?
3. I think that this site is now like many others: it offers goodies and some good approaches to some web design aspects. I think the better you can do if this is your main objective is to be always improving your SEO (it’s good enough by now). But if you want to build a better site (it’s an idea) I see there´s no other site like this offering some feedback and interaction between the readers/visitors. Yes, we can comment every entry/post, but sometimes it’s not enough. What would happen if you try to build a real and strong community around this magazine? You can consider sharing useful links, new portfolios to receive some constructive critics, recommending tutorials, videos or any multimedia inspirational source… You can recruit some advanced users to reply or post about tips and tricks (better than asking and paying for posts).
Hope it helps, feel free to contact me if you want to discuss some topic.
Best regards!
