Analysis of differences between bold <B> and <strong> _ HTML/Xhtml _ web page creation

In terms of WEB standards, B tags are not recommended, but Google's matt once said that B tags have a smaller advantage, although it was later corrected to be the same as strong tags. Search engines are dominated by users. When we cannot determine which one is more advantageous, we may wish to start from the user's perspective and all our webmasters know that they are doing website optimization, the bold keyword of the article is of great benefit to optimization.
However, you will find that strong and B both play a bold role. For example, when a wordpress program is bold, the system uses the strong label by default. Which of the following is better. The following is an analysis of SEO in Beijing. AndLabel usage and difference.

For exampleWebsite OptimizationAndWebsite OptimizationWe can see the same bold effect. Therefore, both B and Strong labels have a rough visual effect.

However, the B tag itself does not have HTML semantics. If you are proficient in HTML, you will soon know that this tag is only bold in HTML code. Strong labels emphasize and increase the tone in HTML semantics.

Data shows that the difference between B and Strong is obvious when blind people use screen readers. Reading B is the same as processing general words. If Strong is encountered, it will increase and pause. In terms of WEB standards, B tags are not recommended, but Google's matt once said that B tags have a smaller advantage, although it was later corrected to be the same as strong tags. The search engine is dominated by users. When we cannot determine which one is more advantageous, we may wish to start from the user's perspective.

Impact of B and strong on seo

The definition of HTML tags is not arbitrary and has certain semantics. From this perspective, labels such as H1 are mainly used on titles, while STRONG focuses more on content applications, such as keyword tagging. Of course, this is not necessarily fixed. For example, some websites also use STRONG labels to emphasize the title. However, it should be noted that excessive use of the STRONG tag is also possible for search engine penalties.

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

Note that the STRONG tag must be written on the page. After experiments, STRONG defined by CSS is useless for indexing and ranking. Although robots can crawl CSS files, it is estimated that the search engine only crawls the content.

In summary: Generally, the STRONG weight is much higher than the B tag, but the role of B tag is basically not discussed here, but for the H tag, the role of STRONG is slightly smaller. Therefore, you can name the labels H1> H2> H3> STRONG.

Starting from this point, I think the search engine is more likely to assign a greater weight to the strong tag. You Can Do SEO experiments and create two pages with the same content, use the B tag and strong tag to emphasize the title or keyword. After the keyword is included, search for the keyword in the search engines to see that the page ranking of the tag package has a higher priority. It is also possible that the weights of the two tags are the same.

So how to use the strong tag currently SEO generally uses the heading label as a means to enrich the text format, it is recommended that "Generally, only one H1 tag is allowed for a page, h2 labels can be increased to 2, and H3 labels can be increased to about 3. Excessive use of heading labels does not have any advantage ." The number of tags is relatively loose. Of course, the main reason is that it does not affect user experience. I cannot emphasize all the main keywords to be optimized? Strong labels emphasize keywords, but if they are used too much, they will "dilute" the keywords and even make search engines think they are cheating. In short, it is natural.
