    Emlog无插件实现SEO优化:标题、关键词、描述

    在模板文件中新建一个headerseo.php,内容为下列代码 
    <?php

        }
        
        $web_canonical = "<link rel='canonical' href='".URL::log($logid)."' />";
        $web_shortlink = "<link rel='shortlink' href='".BLOG_URL."?post={$logid}' />";
        
    }elseif( $type == 'page' ){
        
        $web_title = stripslashes($log_title).'_'.$Body_Title;
        $web_keywords = stripslashes($log_title);
        $web_description = extractHtmlData($log_content, 90);
        
    }elseif( $tws ){
        
        $web_title = '微语_'.$Body_Page.$Body_Title;
        $web_keywords = stripslashes($log_title);
        $web_description = extractHtmlData($log_content, 90);
        
    }
     
    echo "<title>{$web_title}</title>\n<meta name=\"generator\" content=\"Emlog ".Option::EMLOG_VERSION."\" />";
     
    if( $type == 'blog' ){
        if($prevLog){
            echo "\n".$web_prev;
        }
        
        if($nextLog && $prevLog){
            
        }
        
        if($nextLog){
            echo "\n".$web_next;
        }
        echo "\n".$web_canonical."\n".$web_shortlink;
    }
     
    echo "\n<meta name=\"keywords\" content=\"{$web_keywords}\" />\n<meta name=\"description\" content=\"{$web_description}\" />";
     
    ?>
    

    之后再在模板的 header.php 当中加载此文件即可:require_once View::getView(‘breadcrumb-template’);

    这样可以使博客的SEO得到较好的优化,emlog博客强烈推荐
