          在技术层面是有传递出去权重。当然目前一些wordpress主题设置有这个nofollow标签功能。如果手动每个链接加入是很麻烦,

          在wordpress写文章时,严格要求的话是需要在外部链接全部加上nofollow标签。赏金女王2块爆分13万线上网投在澳门的合法性当然我们也可以通过代码实现无插件添加方法。有时内容会引用或分享一些外部链接地址,可以直接找一些wordpress插件安装。这样所有的外线上网投赏金女王2块爆分13万在澳门的合法性部链接就会自动加上nofollow标签。有些外部链接是没有加Nofollow标签,

          //文章自动nofollowadd_filter( 'the_content', 'tin_seo_wl');function tin_seo_wl( $content ) {    $regexp = "<a\s[^>]*href=(\"??)([^\" >]*?)\\1[^>]*>";    if(preg_match_all("/$regexp/siU", $content, $matches, PREG_SET_ORDER)) {        if( !empty($matches) ) {               $srcUrl = get_option('siteurl');            for ($i=0; $i < count($matches); $i++)            {                   $tag = $matches[$i][0];                $tag2 = $matches[$i][0];                $url = $matches[$i][0];                   $noFollow = '';                $pattern = '/target\s*=\s*"\s*_blank\s*"/';                preg_match($pattern, $tag2, $match, PREG_OFFSET_CAPTURE);                if( count($match) < 1 )                    $noFollow .= ' target="_blank" ';                   $pattern = '/rel\s*=\s*"\s*[n|d]ofollow\s*"/';                preg_match($pattern, $tag2, $match, PREG_OFFSET_CAPTURE);                if( count($match) < 1 ) $noFollow .= ' rel="nofollow" '; $pos = strpos($url,$srcUrl); if ($pos === false) { $tag = rtrim ($tag,'>');                    $tag .= $noFollow.'>';                    $content = str_replace($tag2,$tag,$content);                }            }        }    }       $content = str_replace(']]>', ']]>', $content);    return $content;}
