Research on whether Web standard is favorable to search engine optimization

Web standards are not a standard, but a collection of standards. The Web page consists mainly of three parts: structure (businessesflat-out), performance (presentation) and behavior (Behavior). The corresponding standard is divided into three aspects: the structured standard language mainly includes XHTML and XML, the performance standard language mainly includes the CSS, the behavior standard mainly includes the object model (such as the ECMAScript), and so on. Most of these standards are drafted and published by the consortium, and some are standards established by other standards organizations, such as ECMA (European Computer manuhttp://www.aliyun.com/zixun/aggregation/16557). The ECMAScript standard for HTML ">facturers Association".

For some time, there has been a lot of people thinking: follow the Web standards. How much the site has benefited. Unfortunately, the answer to this question is not so clear. To get the answer, we need to know how the search engine "thinks".

When evaluating page rankings. Search engines look at a set of quality signals that may provide clues as to what the Web page is about. And the value of the content. One of these quality signals that we can identify is how many reputable inbound link sources there are. If there are many good site links, it may have high quality content, so when the relevant search results are displayed, it should be ranked top. This quality signal makes Google the boss of the search engine industry, while other search algorithms are based on unreliable quality signals. Obviously, in the billions of dollar search industry, choosing the right quality signal is the most important.

So if we know that the link is a quality signal. That means we should be able to know the relationship between Web standards and SEO. But there is one more question to get the answer. Because search engine companies rely on unique algorithms to survive. So it is very important to protect the privacy of the ranking method. They are unwilling to disclose trade secrets to rivals or those who try to sabotage the system.

How high is the search engine's assessment of standard compatibility? In the overseas SEO industry, someone has done some simple but interesting experiments, to provide a number of views on this issue. He created a series of pages about "Lodefizzle", which he coined, and then labeled them in different ways. By creating a meaningless word, it will only be used on its own page to get a clearer result of the key quality signals that determine search engine rankings.

The findings confirm some general assumptions, but surprisingly, they also overturn other assumptions. He found some results, as follows:

1. Semantic markers such as

The tag keyword does improve the page rank and is better than other methods (such as) to mark the same content.

2. The use of complex nested tables in the layout is, in fact, damaging to some extent the search rankings-presumably because the content of the code is rising, making the page look less valuable.

3. Invalid code, will greatly affect the search rankings. In some cases, the page is even blocked from appearing in the list!
