There are a number of things that you can do to improve your blog.
1. As you need more organic traffic for your blog, you need to provide enough scope for participation. For example, in Techulator, there is enormous scope of people to visit the site, as they don't only get information, they can even contribute. So happens with Yahoo Answers or other Open Forum sites like Parentree etc., where people discuss about a topic, share their knowledge and the site simply keeps running.
2. If you restrict your blog with limited subject matter, the scope of the improvement of your blog also gets limited. In the same tech niche, you can include other subject areas too. In this way, more users will be able to participate and more viewers would find your blog useful for their queries.
3. You can even consider of collecting good original images for your blog which is actually rare in other blogs. For this all you need to do is, taking good quality pictures of tech products and even good screenshots would also help you in this matter.
4. A section of "How to" will help your blog prosper in every sense. But make sure that your suggestion, information all are authentic and they really work.
5. You can keep an option open for "guest posts" so that even your friends or new visitors or members can feel the thrill to see their posts go live on your blog.
6.You can arrange for some giveaways to attract organic traffic. For this you can browse through the Giveaway topics listed in this site itself.
7. You have to make sure that your blog is getting updated with fresh content everyday. And this updated content should get highlighted in your blog.
8. Last but not the least, letting people know about your blog is the final thing which is indispensable for the improvement of your blog. You have to spread the word through as many social media channels as you can apart from the "word of mouth" tactic. Share your blog posts in as many groups or pages as possible in all the social media sites. For this, first you need to join the groups of the similar niche. Even only bloggers group will do a lot of work for you. Keep updating your blog posts in these sites and if possible advertise your blog in free advertising sites.
