Back in February, 2009, some SEO people started to notice major changes in the rankings for quite generic terms in the US. Aaron Wall of SEO book wrote about this.
These changes seemed to be preferentially ranking site that belonged to brands name companies.
Matt Cutts, Google’s head of spam, confirmed on video that there had been a minor update to the rankings but rather than brands the update, nicknamed Vince after the engineer that was working on the project, were more about favouring trust, authority and reputation.
A few months on and many SEOs are reporting that sites that have been well ranked in the top 5 positions for many years, were losing their positions without any possible reason.
In late June a number of people started to notice the Vince update had hit the UK results. Long-standing rankings were also being lowered and wrote about the changes on their blogs. Are big brands being given preferential treatment by Google
It seems clear that only a few terms are being affected by the changes. These seem to be quite generic.
No-one is entirely sure at the moment what factors are required for Google to take your site seriously. Speculation is rife over a number of blogs. Shark SEO had some reasonable suggestions as did David Harry at Fire horse trail.
For definitive examples we have to look at the data and on SEOUnique, they showed data for the time period of the Vince update for the phrase travel insurance. They also suggest changes for other highly competitive generic terms such as car insurance and job and domestic heating oil prices related terms.
iCrossing give more examples of keywords that are effected and they seem to be broadly in the travel and finance. It is too early to say whether other sectors will be effected significantly.
If we are dealing with search landscape where big-brands dominate, how can the little guy compete? If the branding affects only the most generic of terms, then realistically these would be largely out of reach of companies without deep pockets.
It is not all doom and gloom. Smaller companies can still target more specific terms. For many queries a generic term is going to drive traffic but it is probably not converting well. Use of more specific queries is better targeted to conversion and over time may lead to an increase in the site’s perceived trust in Google’s eyes.
