Google's algorithm has had another update, code-named Penguin. Why? Google's Spamfuhrer, Matt Cutts, explains in a blog post. Ahhh! To improve quality. Needn't have bothered reading that, need we? It is what he always says.

What are the effects of Penguin on link-builders? Apparently:

1. Too much anchor-text optimisation will be discounted. If all of your inbound links have the anchor text, "real estate new york", then some of the link-juice will be discounted as unnatural.

2. Out-of-context links will be discounted. If you post on an SEO forum, but your sig-link says, "limo services chicago", then much of the link-juice will be discounted as unnatural.

Will this signal the demise of spam on this forum? Perhaps, in time.

Has anybody noticed their websites moving down in serps? (Mine have all stayed in place, or improved. )
