I'd like to draw your attention to the latest Google updates. As well "Panda" as "Penguin" show an interesting development. The time when spiders crawl blind from link to link is over. Unique content is the new key to high ranking! 65% of SEO's were hurt after Penguin, the update targets all the practices that search engine optimizers have been doing for many years, such as getting paid links or spinning content articles and distributing them just to improve their ranking.
So make sure
- that your link structure is natural.
- quality content by pitching news outlets/platforms
- doing press releases
- guest blogging
