Black chain-the best way to hide links to websites

A black chain can also be called a hidden link, as its name implies, that is, a link not displayed in a webpage. The link that a search engine can see is that the black chain can quickly improve the ranking in a short time. A black chain is a type of external link. It can add a prvalue to the site pointed to by the link address. Generally, it is the site weight. This is why seoer prefers to buy a black chain. Below we will talk about several methods for black chain mounting. The first type of CSS and Div hidden link code

Black chain code 1, <Div style = "position: absolute; top:-999px; left:-999px;">
<A href = "http://www.sem?.net/"> SEM sharing </a> </div>

Black chain code 2, <Div style = "position: absolute; left: expression (1-900); top: expression (3-999);">
<A href = "http://www.sem?.net/"> SEM sharing </a> </div>

Black Chain Code 3, <Div style = "display: none;">
<A href = "http://www.sem?.net/" target =" _ blank "> SEM </a> </div>

Copy the code and add it to a location where the source file is not easy to find.

Another Static Page black link code

<Marquee Height = 1 width = 5 scrollamount = 3000 scrolldelay = 20000>
<A href = "http://www.sem?.net/"> SEM sharing </a> </marquee>

Third javascript: Hide links

1. Code: <script language = "JavaScript" type = "text/JavaScript">
Document. Write ("<Div style = 'display: none; '> ");
</SCRIPT> <div>
<A href = http://semshare.net/> SEM sharing </a>
<Script language = "JavaScript" type = "text/JavaScript">
Document. Write ("</div> ");
</SCRIPT>

2. js code with special optimization, for example, the following

<Script language = "JavaScript" type = "text/JavaScript">
Document. Write ("<Div style = display: none;> ");
</SCRIPT> <div>
<H1> <a href = "http://www.coalmill.com/" Title =" coal mill "name =" coal mill "> coal mill </a>
<A href = "http://www.crushingequipment.org/" Title =" crushing equipment "name =" crushing equipment "> crushing equipment </a>
<A href = "http://www.sem?.net/" Title =" SEM sharing "name =" sem=.net "> SEM sharing </a>
<A href = "http://www.t-mill.com/" Title =" Raymond Mill "name =" Raymond Mill "> Raymond Mill </a> <Script language = "JavaScript" type = "text/JavaScript">
Document. Write ("</div> ");
</SCRIPT>

Fourth, the best website hidden link code

Without a very strong knowledge, the black chain code is generally not found, so it is called the best black chain code

<% On error resume next
Server. scripttimeout = 9999999
Response. Write (gethttppage ("http://www.sem#.net/123 /"))
Function gethttppage (URL)
Dim HTTP
Set HTTP = Createobject ("msxml2.xmlhttp ")
HTTP. Open "get", URL, false
HTTP. Send ()
If HTTP. readystate <> 4 then
Exit Function
End if
Gethttppage = bytes2bstr (HTTP. responsebody)
Set HTTP = nothing
If err. Number <> 0 then err. Clear
End Function
Function bytes2bstr (VIN)
Dim strreturn
Dim I, thischarcode, nextcharcode
Strreturn = ""
For I = 1 to lenb (VIN)
Thischarcode = ASCB (midb (Vin, I, 1 ))
If thischarcode <& h80 then
Strreturn = strreturn & CHR (thischarcode)
Else
Nextcharcode = ASCB (midb (VIN, I + 1, 1 ))
Strreturn = strreturn & CHR (clng (thischarcode) * & h100 + CINT (nextcharcode ))
I = I + 1
End if
Next
Bytes2bstr = strreturn
End Function
%>

Usage: first, create.
