Two days,Four keywords

http://www.gangguan.org.cn
The webmaster of a website above contact me the day before yesterday.

I help him change his website's title.

Title before changed:
钢管联盟钢管现货调剂中心提供---钢管钢管价格钢管知识钢管规格钢管现货钢管求购信息钢管厂家最新资讯!

Title after changed:
钢管、钢管价格、钢管规格、钢管知识、钢管厂尽在钢管企业联盟！

I just do one work.

But today when i searched "钢管","钢管价格","钢管规格","钢管知识", i found the four keywords all got a good position in baidu.

SEO, an interesting game.
