hi... after panda and penguin update we are focus only quality work.

like before update we did submit 1 content in 10 article sites but now we are submit one content only 2 and 3 websites.

First you need to optimize your site using meta tags, title tags, quality content, optimizing your site images and then you need quality backlinks.

After the Penguin update, I suggest the best thing to do would be White Hat SEO. The backlink generation you spend time on, might just go waste if they are irrelevant or low quality.
Generating high quality backlinks from high PR sites would be the best thing to do for SEO.

The best seo techniques after Google penguin update is to make a high profile do follow back-links. Search engine mostly sees the high quality back-links which are coming from the relevant sites.

Quality backlinks are the most important thing after Penguin update. You need to check your backlinks and make sure that you remove all the bad ones or you won't get high rankings in search results. Also make sure that you have selected good keywords and use them A LOT when making content to your website.

Some incredible information shared here, worth reading it. Anyhow I suggest SEOClerks.com to everyone who is looking for quality SEO services or any website related services.
