Analysis of the difference between bold and _HTML/Xhtml_Webpage Production

All of us webmasters know that when optimizing a website, bolding keywords in articles is of great benefit to optimization.
But if you are careful, you will find that strong and b also play a bold role. For example, when a wordpress program is bolded, the system will use the strong tag to bold by default. So which one should be better? Below, Beijing SEO will analyze the usage and differences of and tags.

For example, in Website Optimization and Website Optimization we see the same bolding effect. Therefore, the B tag and the Strong tag are visually bold.

But the B tag itself does not have HTML semantics. People who are proficient in HTML will soon know that this tag only means bold in the HTML code. The Strong tag is emphasized in HTML semantics, indicating emphasis and emphasis in tone.

Data shows that when blind people use screen readers, they can clearly see the difference between B and Strong. When encountering B, read it in the same way as ordinary words. When encountering Strong, it will be emphasized and paused. According to WEB standards, the use of B tags is not recommended, but Google's Matt once said that the b tag has a slight advantage, although it was later revised to have the same advantage as the strong tag. Search engines are user-oriented. When we cannot judge which one has more advantages, we might as well start from the user's perspective.

The impact of b and strong on seo

The definition of HTML tags is not arbitrary and has certain semantics. From this perspective, tags such as H1 are mainly used in titles, while STRONG focuses more on content applications, such as the identification of keywords. Of course, this is not necessarily fixed. For example, some websites also use the STRONG tag to emphasize the subtitle, which is not a bad idea. But it should be noted that excessive use of STRONG tags may also lead to search engine penalties.

Judging from the definitions, semantics and usage of STRONG and B tags, STRONG has slowly replaced the B tag. From the perspective of WEB standards, this is also a normal phenomenon. Google has also slowly increased the weight of STRONG.

One more thing to note is that the STRONG tag must be written on the page. After experiments, STRONG defined through CSS is useless for inclusion and ranking. Although robots can crawl CSS files, it is estimated that search engines only crawl the content.

In summary: Generally speaking, the weight of STRONG will be much higher than that of the B tag. We basically don’t discuss the role of the B tag here, but for the H tag, the role of STRONG is slightly smaller. Therefore, we can basically rank these tags: H1>H2>H3>STRONG.

Starting from this point, I think search engines are more likely to give the strong tag a greater weight. You can do an SEO experiment and make two pages with the same content, and use the B tag and the strong tag to compare Emphasize the title or keyword. After waiting for inclusion, search for this keyword in major search engines to see which page wrapped with the tag has higher priority. It is indeed possible for two labels to have exactly the same weight.

So how to use the strong tag? Currently, the SEO industry generally uses the heading tag as a means to enrich text forms. The suggestion is "Generally speaking, a page is only allowed to have one H1 tag, and H2 tags can be increased to 2 if appropriate. , H3 tags can be increased to about 3. Excessive use of heading tags does not have any benefits. The control of the number of "tags" is relatively loose. Of course, the main thing is to not affect the user experience. It is impossible to optimize everything. Should all the main keywords be emphasized? The strong tag emphasizes keywords, but if used too much, it will "dilute" the keywords and even cause the search engine to judge it as cheating. In short, nature is fine.
