At first there is no plan to write black hat SEO techniques in this series of articles, after all, black hat is not worthy of praise. But conversely, it would be a good thing if you could broaden your mind with a simple black hat technique. Because the field of black Hat sometimes need to SEO involved more in-depth, perhaps also can let a person more in-depth understanding of SEO is not limited to the current widely circulated methods.

Most of the SEO methods I see at home are very monotonous. For example, most of the foreign trade to do the site search, classified information, most of the exchange of links, very few can see some of the best SEO practices in foreign countries like the SEO practice. It is these methods that make me think SEO is a very interesting thing, and therefore put into it.

Specific case: http://autos.yahoo.com/

It is recommended that you use the Chrome or Firefox (with Firebug plugin) to "review elements" of the text underneath the page, as shown in the figure:

Notice the red-framed part of the picture, it doesn't have any content, just a few HTML tags.

The second part of the series mentioned that a search engine might use ID and class names to determine what a block is doing, and the purpose of the Yahoo Autos page is to tell search engines that this block is the recommended block.

What is the significance of the relevant recommendation block? "Search engine-Principles, practice and systems" it has been mentioned that the page above the block is roughly so divided: the text, related links, there is no extraneous noise block (but the actual search engine will be more detailed, that is, after all, the old book), and related links are often in the text below. If the reverse, the relevant links above more likely to be the text, so that the rules of the body is also very reasonable, because the text is often difficult to extract than related links. Actually to do the text extraction, it will be difficult to extract more understanding.

Yahoo's ultimate goal is to ensure that the <div class= "Descript" > This block is considered a body block by search engines.

If this is not the case, the text content of this block is very small, the search engine is likely to be above the page those words more than the block as the text, and those content and "car" This topic is not very relevant to this page SEO traffic will be very bad.

Also interesting is that Yahoo is very unrestrained to its footer called "Yat-seo-foot."

The same idea may be applied to a wider range of applications. For example, it seems the simplest Enterprise station optimization, the original page has a section of the SEO value of the text, and the customer is unwilling to change, at this time if you want to ensure that the content of their added can indeed play a SEO role, you need to use a similar method. Although for Baidu, Yahoo's black hat technique may not be directly applicable. But the search engine to judge the text of the page, is generally combined with a variety of factors to consider, so long as the SEO to understand the common factors will not have problems.

Finally there is a question that may be puzzled, Yahoo uses such a covert SEO method How do I know? Near intuition. When you see Yahoo, it does its own search engine, SEO nature will not be too bad. and see this page footer thought, if not SEO, who will add descriptive text in the footer? And if it is simply classified as a way to elevate the density of keywords, at least it's something I never admired. Therefore, the habitual view of the source code, and finally mining the content described in this article.
