Let me remind you that Google Panda 3.6 was refreshed on April 27th. Google plans to push out a refresh on Panda and Penguin every one to two months.
The main purpose of algorithms is to return high-quality sites to Google users. Again websites with poor content and low-quality links will be low-ranked.
Make sure you have a unique and keyword-targeted content. Conduct a keyword research and choose the ones that describe your business the best. Don’t forget to keep to proper keyword density. Websites with stuffed keywords trigger spiders’ spamming, i.e. preventing a website or a web page from being indexed.
In addition, achieving one-way links from high-ranked appropriate websites is one of the most effective ways for website optimization.
