If it is three or four keywords, then it is basically enough to focus on the homepage. But if the number here refers to ten twenty or more, you need to arrange these keywords appropriately throughout the website, rather than just relying on the home page. In general, the number of keyword optimizations should be at least dozens or more, except for so-called single-page optimization.
For example, like the stone member zeroth asked in this post:
The word tourism in Yunnan is very big. The following good words are: Kunming Tourism, Lijiang Tourism, Dali Tourism, Tengchong Tourism, Xishuangbanna Tourism, Shangri-La Tourism, Linyi Tourism, how do I connect them? They all belong to Yunnan tourism. The first travel site will have these sections, but I don’t think they have much connection, so it doesn’t work. How can we better connect them? Or to put the ranking of these words on a station as much as possible.
The usual practice is to put the most important keywords on the homepage, such as the Yunnan tour in the above example. Other keywords at the second level are placed on each column or channel page. If you have a longer tail and belong to the third level of keywords, you can use the content page to optimize.
On the home page, the main keyword is the focus of optimization. From the page title, bold emphasis, Hx tags, the number of positions where the keywords appear, it is more prominent than other words.
The second-level keywords are not allowed to appear on the homepage. In fact, the second-level keywords should appear on the homepage because they have a strengthening effect on the main keywords.
Like the above examples, Kunming, Lijiang, Dali, Tengchong, Xishuangbanna, Shangri-La, and Linyi are not related to each other, but they are closely related. The viewer knows that these place names belong to Yunnan and are closely related to the theme of Yunnan tourism.
Search engines also know this through semantic analysis. This semantic connection is not literally understood, but is derived from a large amount of statistical data. Search engines are smart enough.
At least the above secondary keywords on the home page will appear in the navigation link. If it is me, it will appear in the main body of the page as appropriate, and link to the corresponding column and channel page.
The longer-term words of the third level, such as the specific tourist attractions inside Xishuangbanna, can be placed on the specific content page below the Xishuangbanna column. Similarly, these content pages will enhance the semantics of the channel page and the home page, rather than being unlinked.
In this way, the keyword optimization is distributed, and the entire website will have a strong logical and semantic relationship system, which is shaped like a pyramid. The home page is the word you most want to rank, and the most difficult word. The entire site highlights the keywords of the homepage, both in terms of semantics and links. The second-level words are distributed on the channel page. These words are relatively weak in competition, otherwise it is very likely that they will not be placed on the channel page.
The premise of the multiple keyword optimization methods mentioned above is that the keywords you want most are limited to a maximum of three or four popular words. If the desired secondary keywords are also popular, you may want to make a separate website, all on the front page to achieve results. On the column page, since you are unlikely to create a lot of good links for all the section pages, it is more difficult to place the popular words, unless you can really make the site a very authoritative Standing, that is another matter.
