tags as the most popular SEO means, in the early days of SEO was known, the webmaster so set up and significantly improve the site's search engine rankings greatly excited. But with the development of Black hat SEO, search engine can no longer tolerate the label on search engine ranking operation means. So gradually the weight of the label is more and more inconspicuous. Later some SEO feel keywords tags are basically abandoned. You go to observe a lot of foreign SEO nature website, even have no this setting. If you have a high level of SEO technology, you can use the label. Matt Cutts once said that 40% of websites don't have the code to meet the standards, but they won't give up. So no keyword,deion spiders can still search you. The following describes my view of the label.

The benefits of the label

Label this is relatively old and SEO the most basic things, but it is necessary to elaborate. Tags are more conducive to search engine analysis of the page, tell the spider what the content of this page. At the same time in the label into the keyword can be a certain weight to enhance the keyword ranking. Title has a relatively high weight, Web page if the representative of a person, title on behalf of the person's face, so reasonable title set is necessary. When your home page is a comprehensive content aggregation, spiders are very likely to analyze this page is what is the main content (ignore the external link effect). Many times the search results appear in the summary is Deion content, the site is particularly common home page. So Descrition set dependencies is necessary, you always do not want to search the summary appears to be the site navigation or irrelevant information, even if the rankings are not attractive before the click. As for keywords do not do specific elaboration, many SEO articles have been told enough.

The disadvantages of the label

A very large feature of the label is set by Webmaster, and search engine in the constant promotion of the fairness of search results, if the label on the ranking is too strong, the search engine will be webmaster or seoer lead, so the search engine in the continuous integration of other factors to measure the content and quality of the Web page. But the weight is in, and the search engine to give up also need to develop to a certain extent, so for the keyword stacking, content is not related to the problem can not be fundamentally resolved. But the search engine can use certain parameters to mark the label. The correct correlation of a score, not set a score, set not related to a score, but for the fight against cheating, the irrelevant label is certainly the lowest. So do not give yourself a disorderly setting, which is disadvantageous to the rankings, not because of understanding SEO and counterproductive.

How labels are set

Search engines do not give a specific ranking algorithm, but can be seen from the Webmaster Guide to use the clues.

Google's webmaster guidelines are described below:

the following references:


please do not use hidden text or hidden links.


do not use hidden or deceptive means of redirection.


please do not send automatic inquiries to Google.


please do not load Web pages that use irrelevant keywords.


do not create multiple pages, subdomains, or domain names that contain a large amount of duplicate content.


do not make Web pages that have viruses, trojans, or other unwanted software installed.


do not use "bridge pages" designed specifically for search engines, or "threadbare" (cutter), where original content with little or no original content, such as an affiliate program, is rarely used.


If your site participates in an affiliate program, make sure your site adds value to it. Provide unique and relevant content that gives users reason to visit your site first.

These are some of the most common methods of Black Hat SEO, and fourth clearly points out that you should not load pages that use irrelevant keywords. Then synthesize some other operation ranking means reverse backward push, get the label set idea:

1. Appropriate repetition of keywords

Keyword stacking is an effective way to increase ranking, so set up keywords in title,keywords,descrition and include as many times as possible, but not close to the stack.

2. Combination of keywords

Many around the keyword set more long tail, related keywords can strengthen the main keyword, so in the control of the length of the label to set a long tail, related keywords to further avoid stacking danger, the length of reference search results to intercept the lengths.

3. The same label set trade-offs

Many web site programs have certain limitations on the label settings. such as some ASP Web site management system, the column set label for the same. At this time please use the label carefully, if all of your columns are related to the key words, it is recommended to set up m, if the contents of the column between the larger difference, the proposed synthesis of several columns set Deion, give up keywords. and the content label is the same words proposed to abandon the establishment of keywords and decrition. Otherwise, it is not worth to fall the weight of the unrelated charges.
