多添加内部链接对网页排名是有很大好处的
插件wp-keyword-link可以实现自动内链
由于插件使用太多造成服务器负担,所以会改wordpress的还是使用代码吧

$match_num_from = 1; //一篇文章中同一个关键字少于多少不秒文本（这个直接填1就好了） |
3 |
$match_num_to = 10; //一篇文章中同一个关键字最多出现多少次描文本（建议不超过2次） |
5 |
add_filter('the_content','tag_link',1); |
7 |
function tag_sort($a, $b){ |
8 |
if ( $a->name == $b->name ) return 0; |
9 |
return ( strlen($a->name) > strlen($b->name) ) ? -1 : 1; |
12 |
function tag_link($content){ |
13 |
global $match_num_from,$match_num_to; |
14 |
$posttags = get_the_tags(); |
16 |
usort($posttags, "tag_sort"); |
17 |
foreach($posttags as $tag) { |
18 |
$link = get_tag_link($tag->term_id); |
19 |
$keyword = $tag->name; |
21 |
$cleankeyword = stripslashes($keyword); |
22 |
$url = "<a href=\"$link\" title=\"".str_replace('%s',addcslashes($cleankeyword, '$'),__('View all posts in %s'))."\""; |
23 |
$url .= ' target="_blank"'; |
24 |
$url .= ">".addcslashes($cleankeyword, '$')."</a>"; |
25 |
$limit = rand($match_num_from,$match_num_to); |
28 |
$content = preg_replace( '|(<a[^>]+>)(.*)('.$ex_word.')(.*)(</a[^>]*>)|U'.$case, '$1$2%&&&&&%$4$5', $content); |
29 |
$content = preg_replace( '|(<img)(.*?)('.$ex_word.')(.*?)(>)|U'.$case, '$1$2%&&&&&%$4$5', $content); |
31 |
$cleankeyword = preg_quote($cleankeyword,'\''); |
33 |
$regEx = '\'(?!((<.*?)|(<a.*?)))('. $cleankeyword . ')(?!(([^<>]*?)>)|([^>]*?</a>))\'s' . $case; |
35 |
$content = preg_replace($regEx,$url,$content,$limit); |
37 |
$content = str_replace( '%&&&&&%', stripslashes($ex_word), $content); |
将上面的代码添加到wordpress主题中的functions.php这个文件中,保存就ok了,效果跟我这里的一样,
添加之前记得备份.
