织梦DedeCms5.7全站按TAG和关键字调用相关文章方法，可单用tag来调用相关文章，也可用tag+keyword来调用相关文章（默认tag优先于keyword，可以自己排序），非常适合SEO，经测试效果极佳。
1.把下边代码保存到文章模版的适当位置
<divclass="xgwz"><dlclass="tbox"><dt><strong>相关文章</strong></dt><dd><ulclass="c1ico2">{dede:likearticlecol='2'row='10'titlelen='42'eregtype=all|tag|keyword}<li><ahref="[field:arcurl/]">[field:title/]</a></li>{/dede:likearticle}</ul></dd></dl></div>2.把下边的php代码替换掉include/taglib/likearticle.lib里的代码
