Hello, I have a blog. 50% traffic is from google (organic). Is there any possibility to optimize blog for search engines with 100$?
Sure, why not? A couple of quality content and a few well positioned quality backlink might do the trick.
Yes it's possible. and doing this couple of thing your blog are optimization a free. Try to include the fresh content daily or weekly. try submit blog in social bookmarking site.

backlinks backlinks backlinks - all relevant backlinks and nothing else.all the quality posts are needed only if you want to gain popularity among your audience.but for traffic a little bit of keyword analysis and relevant backlinks are needed .
What is the topic of your blog, and how competitive is the niche? If it is not about a super-competitive topic (or topics), and you have the patience to nurture it and add new, fresh conent on a regular basis, you really can do the work yourself. Spending only $100 (one time) is more than likely not going to make a lot of difference. You won't get much content and optimization for that price, in my opinion...at least not more than you could do yourself in your free time.
Still 40 % are coming from search engines. Are you not glad of that? If I were to choose, I would not go for 100% organic traffic. Referring sites and direct traffic are still relevant for your site, it can be a good indication of high conversion and ROI.
