The optimization of website code is also an optimization measure in website optimization SEO website optimization Is very important. Although HTML code is a language that programmers should be proficient in, the optimization of HTML code should be a skill that SEO specialists should be proficient in.
As a qualified SEOer, we don't need to be proficient in HTML code, but we need to understand how to optimize website code. For example, some content in our website is important content, which requires us to add additional value to important content, so that we can get the attention of search engines. At this time, we can mark important content through HTML code, After marking important content with HTML code, search engine spiders will know what content should be given higher weight when crawling your website.
Sometimes our website often has some changes, and every change will leave some useless code. Too much of this useless code will affect the opening speed of the website, even reduce the spider's good opinion of the website, reduce the overall score of the website. This is part of code optimization, eliminate the useless code in the website, and improve the opening speed of the page, Increase the friendliness of spiders to the website, so as to increase the overall score of the website and achieve the optimization effect. So, how to optimize the website code in website optimization? The following is Shangpin China Website construction company We will give you a detailed introduction.
1. Title tag
Usually, we need to set a title for the website in the website. Some secondary development programs can set the title of the website in the background of the website, but for some self-developed websites, we need to set the title in the code, and title is the title code. Spiders browse our website through the code, not the visual page when we see the website, The title tag is used to tell the spider what the title of our website is. From the perspective of SEO, we usually add the main keyword of our website to the title tag to increase the matching degree of the website. The title tag is very important for the website. Therefore, we must not ignore the title tag setting of the website when we optimize the code of the website.
2. H label optimization
The optimization measures of H tag in website code belong to one of the code optimization measures. I also introduced the use of H tag in the previous article. Today I will explain how to optimize H tag. The h1-h6 tags are called H tags. H1 tags are the most weighted tags in H tags. Usually, H1 tags are only allowed to appear once on each page of the website, From the perspective of SEO optimization, we usually place the H1 tag on the most important content of each page. For example, the most important keyword of my blog is Harbin SEO, so I put the H1 tag on the title of Harbin SEO. There must not be multiple H1 tags on the same page. H1 tag can only appear once in each page, Other H tags can appear many times, but generally only H1 tags are used. If you are not good at using H tags, it is recommended not to place them in the website. Because if there is no H tag in the website, the spider will distribute the weight of the website to all content, and will not focus on one content.
3. Nofollow tag
Before the webmaster tool could not detect nofollow in the friendship link, many unscrupulous people used the nofollow tag to exchange friendship links. We all know that friendship links can let two websites transfer weight to each other, and adding nofollow in the code of friendship links is equivalent to telling spiders not to grab the link, This will lead to your website will not get the weight transmission effect of the other party's website. Because in friendship links, although we link to the other party's website, we will not spread the weight of our own website, but when the number of friendship links exceeds a certain number, we will spread the weight of the website. Therefore, through nofollow, we can achieve the effect that there is no limit on the number of friendship links, Because nofollow doesn't need to transfer weight to the other party's website, it can exchange many friendship links. But after the webmaster tool can insist on whether the other party's website has added nofollow tags to our friendship links, few people add nofollow tags to friendship links, Most of them add nofollow in robots.txt to guide the spider to which pages of the website are allowed to be crawled and which pages are not allowed to be crawled.
4. Keywords tag
The keywords tag and the title tag are set together. If you use the secondary development program, you can set the title tag and keywords tag together in the background. The keywords tag represents the keywords of the website. A classmate asked me a few days ago why some websites do not set the keywords tag, For such websites that do not set keywords, they usually focus on marketing and promotion, build their own website's brand word traffic, gain a large amount of traffic by increasing the relevance of the website's long tail keyword ranking through high-quality content of the website, and prevent the decentralization of website weight. If you are proficient in marketing and promotion, you can optimize the website without setting keywords of the website.
5. Description tag
The description tag is usually used to fill in the description information of a website. When we search for a keyword, we see that the description of the website displayed below the snapshot is set through the description tag. Some people think that the description tag does not have much impact on the keyword ranking of the website, so we do not set the description tag of the website. In fact, we can find that by careful observation, When we search for a keyword, if the keyword appears in the description below the snapshot, it will also be displayed in red font, but only part of the description will be displayed, not all of the description content will be displayed, so when we set the description tag of the website, The keywords of our website appearing in front of the description information will also increase the keyword matching degree of the website, increase the relevance information of the website, and help the ranking of website keywords.
6. ALT Label
ALT tags are usually used to add to website images. For search engine spiders, they can only read HTML code content and text and digital content, and can't read out what is in the website image. If you add your own image to your image, the spider will not know what is in the image if you don't tell the spider, The ALT tag is to tell the spider what the content of the image is, which is also equivalent to the description information of the image. The description information of the image can also effectively increase the keyword density, but do not add the ALT tag in order to increase the keyword density. We just use the simplest language to describe the information of the image in the ALT tag, The content of the best pictures should be related to the content of our website, because spiders will not only include the content of the website, but also include the pictures of the website, so that the pictures can be displayed in the Baidu gallery, and ALT tags can let the pictures be displayed in which categories of pictures.
Summary of marketing website construction company: for the website optimization, we should first improve the quality of website content, and then pay attention to the structure of the website and the code of the website. Don't underestimate the importance of the website code. Sometimes the code setting of the website is not enough, which will lead to the website being demoted or even hit the K, so, We must do a good job of code optimization measures when optimizing the website.
