Some of them have been around for years but have been largely ignored by the SEO industry. Others are well known by SEO practicioners but completely off the radar for the general public, it seems. Last but not least there are terms from adjacent industries we now have to deal with in SEO. It’s 2011 – we have flying cars by now! – so it’s time to adopt new terminology as well.
503
Most of you probably know what a 404 code is. SEO pros use 301 redirects as well. What is a 503 though? It’s a code telling the Google bot that a site is temporarily unavailable and not broken for good. You need it when performing site maintenance resulting in downtime. See:

A/B Testing
The process of comparing two (or more) versions of a page to find out the best performing one, i.e. the one that is yielding the highest conversion rate. See:
Advanced segments
Advanced segments allow you to show only particular parts of your site’s traffic in a Google Analytics report. You can customize and save them to return to the same report again. If you are serious about SEO, you use them all the time. A common advanced segment is social media traffic, for instance. See:

Citation
Citation is the equivalent of a link for local SEO, but of course it’s not really the same as a link. It’s more a mention and a link on a site that is relevant for the Google Places algorithm. In a way, citations are even harder to get than links, as only a select few sites get counted for citations. See:

Content farm
A content farm is a site, often a huge one, that produces large amounts of keyword laden, low quality content to flood the search engines. Blekko and Google consider them to be almost as bad as webspam. See:

Content marketing
Content marketing is a new term describing all the means to promote your site online, be it text, images, video or other “rich media”. Content marketing replaces, to some extent, simple copywriting. See:

CRO
Conversion Rate Optimization, or CRO for short, is sometimes referred to as conversion optimization, and is the art and science of streamlining traffic once it reaches your site. In other words, it’s a set of techniques to make the user do what you want them to do on your site, e.g. clicking ads, subscribing, buying. See:
