近期Google算法的更新, 把一批中小型网站群给秒杀了, 主要是惩罚过度优化(Over-optimization)的网站.
导致 Google Penguin 认为过度优化被处罚的主要影响因素为:
- Using aggressive word-for-word anchor text.
- Overusing identical domains.
- Low quality article marketing and blog spam.
- Overuse of keywords in internal and outbound links, Keyword stuffing.
- Duplicate Content & Multiple Pages.
集中表现在: 内容及页面重复, 文章质量低(也有指内容相关性不高的情况), 关键词堆砌的链接, 外链锚文本单一, 反向外链指向首页.
Google Penguin Recovery Tips:
- De-optimize the web site
- Increase quality links to pages
- Make sure link anchor text is more natural
- Remove links from blogrolls
- Scale back the internal link anchor text
- Exact match domains hurt
- Practice negative SEO
- Move content to a new domain
- Build a smaller site with very few pages
- Write better content
- Add more social elements, i.e. Google+ Sharing
- Site audit to determine problem areas
- Think more long term with my site, stop taking short cuts
