How to Optimize Labels and Category

If you're using Labels in Blogger or Category in WordPress. Try to create one word label or category. 

For example : Google, Yahoo, Feedburner, Traffic, HTML, SEO, RSS, Blogging and so on. 

If you want to create two words lables or category then use (-) hyphen between the labels or category. 

For example : Google-Plus, WebDesigning, Google-Products, Blogging-Tips (or) you can join the words like BloggingTips. 

So, if you follow the above rules correctly then it will never shows error like %20% for space while Google crawl your website. 

Happy Blogging:)
