准备开始做正规的seo，黑链代码依旧是用，只是有点特殊而已，当然，自己先测试下，是否可行。
要弄个php文档，记录来访是否蜘蛛还是普通用户，具体就是根据php的$_server[‘http_user_agent’]来进行判断
具体代码如下：
<?php
$tmp = $_server[‘http_user_agent’];
if(strpos($tmp, ‘googlebot’) !== false){
echo ‘谷歌’;
} else if(strpos($tmp, ‘baiduspider’) >0){
echo ‘百度’;
} else if(strpos($tmp, ‘yahoo! slurp’) !== false){
echo ‘雅虎’;
} else if(strpos($tmp, ‘msnbot’) !== false){
echo ‘msn’;
} else if(strpos($tmp, ‘sosospider’) !== false){
echo ‘搜搜’;
} else if(strpos($tmp, ‘yodaobot’) !== false || strpos($tmp, ‘outfoxbot’) !== false){
echo ‘有道’;
} else if(strpos($tmp, ‘sogou web spider’) !== false || strpos($tmp, ‘sogou orion spider’) !== false){
echo ‘搜狗’;
} else if(strpos($tmp, ‘fast-webcrawler’) !== false){
echo ‘alltheweb’;
} else if(strpos($tmp, ‘gaisbot’) !== false){
echo ‘gais’;
} else if(strpos($tmp, ‘ia_archiver’) !== false){
echo ‘alexa’;
} else if(strpos($tmp, ‘altavista’) !== false){
echo ‘altavista’;
} else if(strpos($tmp, ‘lycos_spider’) !== false){
echo ‘lycos’;
} else if(strpos($tmp, ‘inktomi slurp’) !== false){
echo ‘inktomi’;
}
?>
