Chinese New Year holiday, free time compared to more than usual, planning to write something, but also a sort of their own thinking of a collation and record. So there is a "Gossip Search engine Optimization (SEO)" series.

After drafting the outline, "Gossip Search engine Optimization (SEO)" of the opening half of the time, the loss of friends sent an old article: SEO lectures keyword layout, density, relevance and conversion. Chushda's article had already been read earlier and had different views on some of his views. So stop the pen, pause, "Gossip Search engine Optimization (SEO)," The opening of the writing, wrote the "About keywords (word) layout-Gossip search engine optimization (SEO)"

SEO lecture keywords Layout, density, relevance and conversion for keyword layout mentioned in the article:

1, the keyword layout is simply that the keyword appears in those locations on the page

2, Qiu Shi da prefer a centralized layout + decentralized layout of the blending mode

3, evenly distributed keyword, reasonable add keyword

4, the top and the left top of the page focus on the keyword, search engine optimization (SEO) The effect is better

There is a book to be mentioned before I put my opinion. Science Press 2004 published "Search Engine-principles, technology and systems." Do Search engine optimization (SEO), this book can not see. And my point of view or "Gossip Search engine Optimization (SEO)" More will be from the search engine work principle to elaborate.

Back to the question of the keyword layout, search engine spider or crawler a page to crawl (before, in, after the work will be in the "Gossip Search engine Optimization (SEO)" series one by one elaborated, suggested that first read the "Search engine-principles, technology and systems" book, For page analysis, indexing, the content of the index is not just a simple filtering of the HTML code after the data. Search engine has a content extraction action ("Gossip Search engine Optimization (SEO)" series in another article in detail). Simply to know what the page is mainly about, extract the main content, which will remove navigation links, advertising, copyright information, etc. for a site more general content, or the page analysis process of noise. (Do not exclude the search engine will do for the site home to do more special processing, because most of the site's home is linked to the ocean)

and the keyword (word) layout refers to our keywords (words) as far as possible in the page analysis, remove noise after the main content, to avoid the content extraction after the keyword (word) is filtered and caused loss. My advice is: each page should have a paragraph of text content, the content from the link as far as possible.

The interesting thing is, I to Chushda's Chinaseo home did extract the content, only a line of words: "SEO tools, SEO tutorial download Please click here" (personal tools of personal testing behavior ...)
