Keywords are the soul of website optimization. Letting core keywords and related long-tail words rank high on search engines is also the purpose of website construction and website optimization. For a website, it will not work without a certain keyword density, because search engines cannot judge the theme and core of the website. However, if the keyword density is too high or the distribution is unreasonable, it will affect the quality of the website and even cause misjudgment by search engines. The most obvious keyword misunderstanding is keyword stacking, especially between the website title TITLE and KEYWORES/DECRipTION. Many people think that as long as the keyword density is high enough, the website ranking can be improved. But the fact is that meaningless keyword stuffing will not only not improve the ranking, but will also cause a decrease in weight.
Only a reasonable keyword layout can let search engines know that the website is keyword-themed, and it is also possible to effectively increase the weight of the website. Keywords are generally distributed in the website title, keywords and content description, page text, and image ALT description. The so-called three digits of website construction refer to the three places of website title, keyword description, and page text. The same highlighted core keywords appear. There are certain requirements for different positions, keyword positions and frequency of occurrence. Generally speaking, the website title should be concise and concise, the page content should first ensure that the sentences are smooth, and the keyword placement should not be blunt. How to reasonably and effectively increase keyword density in several different key positions?
1. Website title description: core keywords should be as high as possible
Friends who often pay attention to search engines may find that if the title is too long (generally more than 32 characters), it will be intercepted and replaced by an ellipsis by the search engine. This is not to say that this will definitely affect the weight of the website, but a title that is too long will affect the user experience. If not necessary, please limit the website title to 32 characters. In such a short number of characters, the keywords written on the title must be very core words. Moreover, the more core and important keywords must be ranked higher. Maybe this is just a human psychological factor, but the first keywords at least have a good user experience because they can let users understand the theme of the website as early as possible. . Another point that needs special explanation is that from the perspective of optimization, the company name is not the most important. If it can effectively improve the ranking, it is worth sacrificing the company name for keywords.
2. Keywords and descriptions: Do not stack or repeat keywords
Meaningless stacking will not only annoy users, but will also make search engines think you are cheating. Keywords and website content description parts are important parts for search engines to identify web pages, such as the DESCRIPTION part. Generally, as long as how you describe it and the description content is the same as the website theme, Baidu, Google, etc. will generally use this description directly. When keywords are properly and reasonably implanted, when the user searches for them, the searched words or similar words will be displayed in red. From this, we can see that search engines still care about the description of web pages. However, the content description of the website must be a summary of the essence of the entire website. Keywords can be reasonably implanted under the premise that the sentences are smooth, but it should not become a garbage dump filled with keywords. Like the title description, keywords must appear between the keyword description and the website content description, and the main core words must also appear first.
3. Text web page content: keyword distribution is naturally balanced
There is no doubt that keywords appear in the page content, because the text content is the foundation of the website. If keywords only appear in the title and content description parts of the website, but there are very few keywords in the main text, it will not be able to effectively increase the weight of the website. When enriching website content, a natural and balanced distribution of keywords requires keywords to appear several times in the middle of the article, and randomly and seemingly unintentionally at the beginning and end of the article. Practical experience shows that bolding keywords in the content and linking them to the homepage of the website in the form of anchor text can effectively improve keyword rankings. The purpose of this operation is essentially internal links, which tell search engines that this website is based on this keyword.
4. Image ALT description: keyword distribution is diverse and reasonable
Based on current technology, search engines cannot recognize images or Flash, only text. When you encounter a picture, you can use comments to tell the search engine the general content of the picture. For example, a LOGO picture related to the Shanghai website construction company Pilot Technology can be marked with ALT text as "Shanghai Website Construction" or "Shanghai Website Construction Company", etc. Proper use of image description text can effectively increase the keyword density of the website and tell search engines about the relevant content of the image, but it should not be excessive. A more compromise method is to replace them with synonyms or synonyms. For example, website construction can be replaced with website production or website design. This avoids the suspicion of keyword stacking and effectively increases the density of keywords.
5. Sub-navigation and map: core keywords are strengthened and highlighted
It is often seen that on some websites, anchor text links are processed in bold fonts in the form of keywords of the website. In fact, this will bring suspicion of cheating to search engines. One is because these texts all point to the same URL address, and many people directly use the domain name of this website; the other is that there are keyword links lined up in a row, which have no meaning and are just keyword stacking. If this is done in order to increase the keyword density of the website, it is better to say that it ignores the full use of sub-navigation and website maps. Appropriately strengthen keywords in the website sub-navigation and add keywords to the site map. Since the link texts in these two places are different and the URL directions are also different, the effect of emphasizing the core keywords in bold is actually more obvious.
After crawling from a vast sea of links to a website, the search engine spider will continue to crawl within the website along the links. The purpose of internal links is also to pave the way for search engines and build bridges, and during the crawling process of search spiders, use keywords of different link text types to tell it where this direction is and where the next direction is. Therefore, reasonable keyword layout and reasonable text links are crucial. Professional website construction company Pilot Technology ( www.joyweb.net.cn ) believes that in fact, search spiders are like a person going to a strange place. The title of the website is the name of the landmark, telling the search spider the place name, and the description of the website content is the introduction of a place. Let search spiders know the general summary and background of the website. The link anchor text keywords that appear in different locations in the article are different road signs, always reminding search spiders of the direction of the next link and the destination of the link.
