There are many tips for SEO / SERP ,and you can find them easily in internet . In this post ,I just want to add one more tip for you all .This tip is not from me , I got it from Mr Tinh Tran at eblogviet.com  . He wrote in Vietnamese ,so I translated and post it here for you all . I hope it helpful .

If you go to Mashable blog  and see posts, you may notice that they always use short URL for their article ,and the URL contain only main keywords . Title of article maybe long ,but URL always short and focus on main keywords . For example ,there's a post with title “9 Ways to Do Good With 5 Minutes or $25“ but the url is not /9-ways-to-do-good-with-5-minutes-or-25/ as default , it is only /social-good-micro-lending/ .You see ,the URL focus on main keywords .

So what is the secret beyond this tip ? when bots/spiders from search engines crawl a page to index ,they will find main keywords in this page ,start from url to page title ,and continue to the end of post . If your URL short and focus in main keyword, it will help the spiders decrease time to examine the post for indexing ,and make your site a better rank in search result .

How we apply this tip in Blogger ? Very easy ,my friends . At first , write a post title short and focus on main keywords . Publish your post . Now your post is published with a short and SEO friendly URL . After that ,you can back to Dashboard and choose Edit Post ,change the post title to any title you want and publish it again . The first url is still kept while the post title is changed as you want . That's all . It will take only 30s from you but quite good for SEO.
