Disclaimer: Some of the methods mentioned in this article may lead to the penalty of search engine, for reference only, please use carefully!
Many people may often search for certain keywords when they find other people's site ranking very good, but find no reason, in fact, many sites are using the key words of the method of the stealth, the following I combined my years of optimization experience, summed up some of the key words of stealth methods, may be some people will ask, why do you want to hide the keyword ah? Good question, because we in the SEO when both want to please search engine, and do not want to offend browsing users, so sometimes it is necessary to use this method, if it is not clear, it seems that you have not started, go back to the practice of meditation, back to see this article.
One of the invisible Dafa: Deception
Hidden forms
Sometimes we want to put all the keywords in the first part of the page without being silly, which is very difficult, especially when you are using pictures at the top of the page. Of course, there are many sites to the keyword simply listed on the top of the page, but too unattractive and professional. There are many ways to solve this problem, among which the invisible form tag is the least visible to the viewer. These tags should be placed in the <body></body> of the page and look like this:
<input typ= "hidden" value= "your keyword here" >
Some search engines will recognize this, and some do not recognize it (which requires us to practice and research to know). The advantage of these methods is that he is completely invisible to the viewer, and the search engines that recognize them will consider this to be the text. This label should be placed immediately after the <body> tag, all other content, because some search engines will look at the first 2000 bytes of a file, so should be placed in front of all other tags.
Stealth Dafa bis: weeding
Set the text color of the page to the same color as the background, and set the font to the smallest number 1th font
Considering that some search engines do not recognize or even punish the content of the keywords hidden in the <input type= "hidden" > form, we will think: what can we do to add keywords without affecting the display of the page? It is not visible that "keyword-cut" provides a possible method, however, these techniques are also considered a bad online etiquette by the search engine penalty.
In this technique, will let the keyword text color and their background color like, these keywords also occupy the space, although the viewer can not see, but search engine to see.
For example, if the background color of a particular page is white, this can be defined as:
<body bgcolor= "FFFFFF" >
At this point, you want to let you add the keyword to use the same color, you can change the color of the word:
<font color= "#FFFFFF" size= "1" > contains words for keywords here </font>
This method has been identified by some search engines, but we know that our goal is only to ensure that viewers can not see the words we need to cut the keyword, then the search engine to recognize this way, then we can also modify, Because the search engine it is to identify the background color code and text color code to determine whether cheating, but if our background is the use of background images, the search engine is not able to identify the color of the background picture, so even if the page text and background image color, search engines can not identify. Of course, for size=1 this 1th font, we still have to use caution.
The third of stealth Dafa: the
Annotation Stealth Method
It's a good habit of programmers to write comments in code, because sometimes if there is no annotation, some of their programs after a long time they also know not to come out, so the comments for each page is in fact necessary, but this method is seoer used to cut the keywords, not to be made. We also have to admire the professional spirit of the optimization staff, do everything possible and means to achieve their own purposes. The usual format for annotations in HTML is
<!--put the keyword you need here.-->
This code is visible to some search engines, but the viewer is invisible, this part of the text will not be displayed when browsing the page, you can in this code to place the key words you need, but not too much to cut, avoid.
Stealth Dafa Four: Sly
CSS Stealth method
In addition to the previous stealth methods, there is a more advanced stealth mode, that is, CSS to set the style of the page. Because the general search engine may only identify the code in the page, but the code in the referenced CSS file can not be recognized, use this method also need to be more familiar with CSS code, and know how to reference CSS files. Many people know that search engine <h1> font is very important, but <h1> very large, placed in the page layout is inconvenient, but also affect viewers to watch. At this point we can use CSS to control the style of the font. For example:
<h1> Place the keywords you need </h1>
And then add this code in the middle of the page <head></head> tag.
<style type=text/css>
H1 {font-size:13px; COLOR: #FFFFFF}
</STYLE>
The above code is to set the font size, one is to set the font color, do not tell me you do not understand how to hide your keywords, if you need to set the color of the page background, to use
Body {background-color: #FFFFFF}
Generally we create a css.css file, write the CSS code in this file, and then refer to the file in the page, referencing the method:
<link href= "Images/css.css" rel= "stylesheet" type= "Text/css" >
Using the form of a reference is better than the <head></head> effect written directly on the page.
In addition to the CSS stealth method, there is also a layer of hidden property settings, which is directly in the layer of the properties of the set, so classified into the CSS stealth method, such as:
<div style= "Display:none;" > Place the keywords you need to cut </div>
In fact, for all the HTML code tags can be set hidden properties, but some search engines are not allowed to set this, so please be careful to use, to this part of the friend can not see, you may first learn some basic CSS knowledge, and then to learn.
Stealth Dafa Five: Treason
Merry-go Stealth Method
Merry-go may have some friends unfamiliar, this is a kind of web page special effects, in fact, is a kind of HTML code tag <marquee>, we want to stealth is to let the viewer invisible, and let the search engine can identify, then <marquee> The label is a good choice, and the search engine for <marquee> in the text is also more important, this method in 05 years or so used more commonly, now we are rarely used, but the appropriate use or have effect. Specific use methods such as:
<marquee height= "1px" direction=up scrollamount=1> Place the keywords you need </marquee>
The explanation for the above code height= "1px" is to try to keep the Merry-go slim so that it doesn't take up a lot of space, so after setting merry-go, it looks like there's basically only one line. Of course, some people will think why not set him a bit 0px, oh, you try to know.
Well summed up so much, this is some SEO heretical, that is, the so-called Black Hat method, please use carefully. In my next article I will talk about "how to do keyword swarm optimization and site content structure design" about keyword Group optimization design I applied to the www.taofw.cn, the effect is very good, I will share to everyone.
