After introduction of Google Panda the whole algorithm of Google Indexing system changed. Now the top rankings cannot be achieved by using all the earlier techniques. So you need to work with only some techniques that still works. Remember that traffic from search engines is very important because each and every person searches his need using the search engines and Google is one of the top search engines. So SEO of your blog is very important because only then you will get the good rankings in the search results. But if you don't optimize your blog then your links will get bad rankings and then we all know that no one will go to the 9th or 10th page of the search results to fulfill his need.
So here I would reflect those techniques that works After Panda..
1. Originality and Uniqueness in Writing
2. Moderately Use Keywords
3.Submitting to Search Engines
4.PR backlinks from Top Ranking sites
