You should first check whether your site or blog got crawled by google. Indexing will only take place if it is crawled. Otherwise wait for a week, or contact Google support if nothing happens.
Don't worry this happens alot. Sometimes it can take a week to get your stream of traffic back. You also have to take account of national holidays. For example in the UK this weekend is a bank holiday and is notoriously poor for traffic. You rankings will come back but it rarely has anything to do with what you have done.
First check your website is still indexed on google or not? site:http://www.yoursite.com If your is indexed then your site is not into sandbox
have you used any PTC site to get traffic . if your goal is just getting traffic without making any profit then participate in any PTC website which gives spam my traffic at low cost
