Increase the signal-to-noise ratio of the Web page code and content optimization denoising

A Web page signal-to-noise ratio is the ratio of text content in a Web page to the content of the HTML tags generated by the text. Generally speaking, the higher the signal-to-noise ratio, the better the quality of our web page, can be based on the search engine for the Web page to grasp the principle to explain: search engine spiders crawl the page, will be heavy on the page, mainly to remove the noise of the Web page, leaving useful information. After the Web page is heavy, the search engine primarily captures the stored data by removing the HTML tag's text content, which can be thought of as not distorting the sound signal, while the resulting portion of the HTML tag content can be considered noise.

　　

The effect of Web page signal-to-noise ratio on SEO

Interested friends may be from Beijing SEO above a paragraph of words quickly learned that today's article is about the site's internal SEO optimization skills, and it's a lot of friends who don't pay attention to this piece, so if you can focus on it, then you may have more advantages than others.

Think about your own optimization methods, is there a lot of people stay in the "content for the king, outside the chain for the emperor," the slogan-type dazed stage, doing the "SEO migrant workers" of the implementation work, every day only know to do the content of the chain, but do not know how much suitable, more can see the effect. This is also the front for everyone to do scientific SEO help us quweicunzhen need to pay attention to a problem, to bid farewell to a stage, we must deeply study the working principle of search engines, and the increase in signal-to-noise ratio is definitely one of them can help us optimize a good station in one aspect.

SEO internal optimization including the inner chain layout, code optimization, keyword layout and content building, and other aspects, in order to improve the signal-to-noise ratio, there are two aspects to be done: code denoising and Content denoising two aspects of optimization.

first, the code to Noise

In the aspect of code optimization, the optimization principle is to reduce the code redundancy of the Web page as much as possible, so that the more pure text content in the page, the easier the search engine to crawl the page. The following two aspects are required:

1, less with pictures, Js,iframe,flash and other search engines to read the difficult code, if you have to use, as much as possible in the separation of these codes, such as a lot of people will flash to do the JS code directly to the Web page to affect the search engine to crawl, where if the split can let search engine spiders jump quickly

2, the use of DIV+CSS style layout page, do not use table this redundancy is higher than the code layout of the page, but also pay attention to the CSS code, as far as possible, Major General CSS directly written to the Web page. For Div also to reduce hierarchy, reduce redundant code.

second, the content to noise

Eliminate the Web page noise, in addition to the above mentioned code optimization, and other aspects of the content and module calls, the most important reason is to improve the content of the Web page and irrelevant content ratio, through the content of the noise, to achieve the goal of optimization.

Good content to show in addition to our website style design, more is to show the content of the site's text, and a page of signal-to-noise ratio or not, a lot of time is determined by the content, how to do the relevant content to show, a very important aspect is to do the relevance of the keyword.

To give an example: SEO outside the chain what kind of good this page from the title is obviously learned that the article is about the construction of the chain of skills, so in the content editing time need to around the outside the chain construction method or strategy to talk about, but this is not enough, also want to add related article link in the content (blue text link part), In setting the article layout, I also targeted the reader to recommend the relevant articles, the following figure:

　　

Outside the chain construction skill related article recommendation

Of course, there are other sections that may be noise modules, these modules are what I think is the content of the noise module, because it is not helpful for this page content topics, such as sidebar, the article's unrelated comments, although it is also related to SEO, but not related to the outside chain construction.

Of course, the idealized is that these modules are also "optimized out", then may be another problem arises: the Web page of the keyword density is too high to reduce the rights of the page. Because once we too much care about the content of noise, remove these noises, it will make certain keywords of the Web page density beyond the rules of Baidu, the weight of this page is reduced. So sometimes some Web content noise is also to weigh and neutralize the purpose, so that the growth of the Web page more healthy.
