All of us webmasters know that when doing website optimization, bolding the keywords of the article is of great benefit to optimization.
But if you are careful, you will find that strong and b both play a bold role. For example, when the wordpress program is bolded, the system will use strong tags to bold by default. So which one should be used better? Below, Beijing SEO analyzes the usage and differences between <strong> and <b> tags.
For example, what we see is the same bolding effect as <strong>Website Optimization</strong> and <b>Website Optimization</b>. Therefore, both the B label and the Strong label are both bold in visual effects.
However, the B tag itself does not have HTML semantics. If you are proficient in HTML, you will soon know that this tag only has bold meaning in HTML code. Strong tags are emphasized in HTML semantics, indicating emphasis and aggravation in tone.
According to data, when a blind person uses a screen reader, the difference between B and Strong can be clearly reflected. When you encounter B, you read the same way as when you deal with general words, and when you encounter Strong, it will aggravate and pause. From the perspective of WEB standards, the use of B tags is not recommended, but Google's matt once said that b tags have more slight advantages, although it was later revised to be the same as the strong tag's advantages. Search engines are mainly users. When we cannot judge which one has more advantages, we might as well start from the user's perspective.
b and strong affect SEO
The definition of HTML tags is not as good as you want, and has certain semantics in itself. From this perspective, labels such as H1 are mainly used in titles, while STRONG pays more attention to the application of content, such as the identification of keywords. Of course, this may not be fixed. For example, some websites also use STRONG tags to emphasize them in subtitles, which is not bad. But it should be noted that excessive use of STRONG tags also has the possibility of search engine penalties.
Judging from the definition, semantics and usage of STRONG and B tags, STRONG has gradually replaced B tags. Judging from the WEB standard, this is also a normal phenomenon. Google has also gradually increased the weight of STRONG.
One thing to note is that the STRONG tag must be written on the page. After experiments, STRONG defined by CSS is useless for inclusion. Although robots can crawl CSS files, it is estimated that search engines only crawl content.
In summary: Generally speaking, the weight of STRONG is much higher than that of B label, and we basically do not discuss the role of B label here, but for H label, the effect of STRONG is slightly smaller. Therefore, you can basically name these tags: H1>H2>H3>STRONG.
From this point of view, I think search engines are more likely to give strong tags greater weight. You can do SEO experiments, make two pages with the same content, emphasize the title or keyword through the B tag and strong tag. After waiting for inclusion, search for this keyword in major search engines to see the page ranking of the tag package, and see the page ranking of the tag package is more preferred. It is indeed possible that the weights of the two labels are exactly the same.
So how to use strong tags. Currently, the SEO industry generally uses heading tags as a means of enriching text form. It is recommended that in general, only one H1 tag is allowed for a page, the H2 tag can be appropriately increased to 2, and the H3 tag can be increased to about 3. There is no benefit to overuse of heading tags. The number of labels is relatively loose. Of course, the main thing is that it does not affect the user experience. It is impossible to emphasize all the main keywords to be optimized, right? The strong tag emphasizes keywords, but if you use too much, it will dilute the keywords and even make search engines judge to be cheating. Anyway, it's good.
