Search Engine Optimization (SEO) has become an essential weapon in the arsenal of every online business. Unfortunately, for most business owners and marketing managers (and even many webmasters), it’s also somewhat of an enigma. This is partly due to the fact that it’s such a new and rapidly changing field, and partly due to the fact that SEO practitioners tend to speak in a language all of their own which, without translation, is virtually impenetrable to the layperson. This glossary seeks to remedy that situation, explaining specialist SEO terms in plain English…

Bad Neighbourhood

A web page that has been penalised by a search engine for using unethical SEO tactics.

Blind Traffic

It’s low quality traffic that isn’t targeted traffic bringing certain visitors using your favorite keywords. It’s usually generated by misleading advertising, spam and other types of online marketing methods.

Browser Emulation

Search engines don’t like the repeated requests to their databases, specially when it occurs for a long time. They suspect that such requests could originate from some software program, not human searchers. Search engines don’t like the softwares imitating this behavior. The reason is because when humans perform browsing, they visit the search engine’s home page first, perform a search, pause between searches they do, request pages at the URLs provided as search results, etc. Of course, some softwares are built in a way that emulate human-conducted browsers’ activities. This action is called browser emulation.

Repeat Visitor

A unique visitor who views a site/blog more than once over a specific period of time.
