Over the last week, there have been reports by webmasters on the Webmasterworld forum that they are seeing large fluctuations in their website's listings in the Google search results, causing speculation that another algorithm change is currently being rolled out.  The Mozcast website shows two peaks in ranking turbulence during the end of October and another peak at the beginning of November, (see Below.)

In 2003 when Born first ventured into the world of search engine optimisation, the title tag was one of the most important elements of a sound SEO strategy.  Other important factors and tactics have fallen by the wayside since then such as the meta-description, meta-keywords, link exchanges and stuffing keywords into link text.

In the post Penguin, Panda and Hummingbird era, inbound links and social metrics now outrank the humble title tag in terms of importance, but if you have all of these in place, a well crafted title tag can give you a further boost in the rankings.

Matt Cutts announced the launch of Penguin 2.1 in a tweet on Friday.  The new update will affect 1% of all Google searches. 

The first generation of Penguin was rolled out in April 2012, it's purpose was to target and remove webspam from the search results.  Sites with low quality backlinks and anchor text which was overly optimised were hit hard. 

In May 2013 Penguin 2.0 saw a complete change to the Penguin Algorithm.  Matt Cutts described how Penguin 2.0 improved upon the previous version.  "The previous iteration of Penguin would essentially only look at the home page of a site. The newer generation of Penguin goes much deeper and has a really big impact in certain small areas."
