Hello everyone, I am the Phantom of the Rain. Web site is user-oriented, so in the process of website optimization, we often talk about the idea is "content is king", this and "outside the chain for the Emperor" does not conflict, if we really can do this two points, it is very good for the site, often we do not good optimization is because of one aspect of this is not done well, One of the most easily overlooked aspects is content, many friends talked about the site to be original, to false original when more pursuit of high-quality, but also some friends generalities said a lot of seemingly very practical operations, but also very much to do some implementation (including my own before a long time is like this) , if not in-depth study of some of the working principle of search engines, in fact, we really do not good seo, or for SEO does not have a clear sense of the heart.

Website content, want to do well, need certain editing ability, before for everyone to talk about "additions and deletions" four words, but only from the content of the original to consider, rarely to analyze the content of the combination of keyword editing, perhaps to one or two points, but also a cursory mention of "around the word" in the setting, For example, asked everyone in the title layout to optimize the keyword, in the first paragraph and end of the layout to optimize the key words, related articles appear, and so on, but why to appear these keywords? Have a friend said, this does not know, also do what SEO, add these keywords is to improve the keyword density of the Web page, density increased, The correlation is improved, and the ranking has the advantage. Let's take a look at an example and you can understand why you want to lay out your keywords like this.

Everyone search "Dior Pink Charm Perfume" Get the search results page before the four-bit is a word of praise, Baidu open platform aggregation of a product search page, "Dior Pink Charm Perfume" Baidu Encyclopedia and Le Bee Network about products of product questions and Answers page.

Dior Pink Charm Perfume Search ranking screenshot

Analyze four page keywords layout:

1, first look at the page directly match the "Dior Pink Charm Perfume" The layout of the word:

Poly-Mei Word-of-mouth page appeared 6 times, breadcrumbs Navigation, page title more important location each appeared 1 times, the content appeared 4 times, and Baidu open platform page, Baidu Encyclopedia page and Le Bee network question and answer page are not directly appear this word.

Conclusion: Search engine rankings in accordance with the full matching principle of relevance, according to this principle is true poly-Mei Word-of-mouth page should appear in the first position.

2, the word will be split into "Dior" "Pink Charm" "Pink charm Perfume" Two words, we look at it in the Web page appears:

A, the layout of the word "Dior":

Poly Beauty Word-of-mouth Page appeared 14 times, breadcrumbs navigation, page title more important position each 1 times, the content appears 12 times

Baidu Open Platform page appears 23 times, category Navigation 1 times, product navigation 22 times

Baidu Wikipedia page appeared 10 times, all for the content appeared

Le Bee network question and Answer page appeared 5 times, breadcrumbs navigation, page title more important position each 1 times, content 3 times

As for these four pages is not very good to show the "Dior" the relevance of the word, these four pages are introduced Dior a single product of pink charm perfume, lack of relevance, so these several pages on the "Dior" the word ranking is not up front. This point from the side of the search engine algorithm should first consider the principle of relevance.

B, for the "pink charm" the layout of the word show:

Poly Beauty Word-of-mouth page appeared 10 times, breadcrumbs navigation, page title more important position each 1 times, the content appears 8 times

Baidu Open Platform page appears 26 times, product navigation 26 times

Baidu Wikipedia page appears 11 times, the page title appears 1 times, the other 10 times for content appears

Le Bee network question and Answer page appeared 4 times, breadcrumbs navigation, page title more important position each 1 times, content 2 times

Check out the keyword rankings for these four pages, Baidu Encyclopedia ranked in the front, Baidu Open platform page in the second, but there are changes in the page, added some not pink charm perfume products recommended, the other two pages in the first 10 pages can not find, that the word does not explain the content of these four pages, Accurate keyword relevance is more able to locate Web pages in the search engine in front of the show.

C, for the "Pink charm perfume" The layout of the word show:

Poly Beauty Word-of-mouth page appeared 10 times, breadcrumbs navigation, page title more important position each 1 times, the content appears 8 times

Baidu Open Platform page appears 7 times, product navigation 7 times

Baidu Wikipedia page appears 8 times, the page title appears 1 times, the other 7 times for content appears

Le Bee network question and Answer page appeared 3 times, breadcrumbs navigation, page title more important position each 1 times, content 1 times

View the four pages of this keyword ranking, Baidu Encyclopedia ranked in the front, Baidu Open platform page in the second, but add some more about the "Pink Charm perfume" product recommendations, Lok Bee Web page ranked third, Poly United States page ranked in the end.

Conclusion: The search engine algorithm must first consider the principle of relevance, and the more accurate to reflect the relevance, but not the site's keyword density higher ranking the better, may be the location of keywords is also more important (by the United States and the peak of the comparison of the page).

3, keyword layout tf algorithm analysis (to gather the United States Word-of-mouth page and the Lok Feng FAQ page for example)

A, look at the number of pages related to the occurrence of words

Le peak question page "Dior Pink Charm Perfume" appeared 0 times, "Dior" appeared 5 times, "Pink Charm" appeared 4 times, "Pink Charm Perfume" appeared 3 times, "Perfume" appeared 12 times

Dior Pink Charm Perfume 871,000

Dior 28.3 million

Pink Charm 2.86 million
