So, now we're getting to backlinks that have relatively little, or even negative value. The value of web directories has diminished dramatically in recent years. This shouldn't come as a surprise. After all, when was the last time that you used a web directory to find anything, rather than just doing a Google search? Google recognizes that directories don't have any real world worth, and so they don't accord much value to backlinks on them. But there is an exception to this rule. Submitting your website to local, industry-specific and niche directories can net you worthwhile backlinks. But if you can't imagine a circumstance where someone would use a certain directory, then it's probably not worth your time.
SEO techniques can be classified into two broad categories: techniques that search engine companies recommend as part of good design ("white hat"), and those techniques of which search engines do not approve ("black hat"). The search engines attempt to minimize the effect of the latter, among them spamdexing. Industry commentators have classified these methods, and the practitioners who employ them, as either white hat SEO, or black hat SEO.[49] White hats tend to produce results that last a long time, whereas black hats anticipate that their sites may eventually be banned either temporarily or permanently once the search engines discover what they are doing.[50] Denver Marketing Solution Click Here
