Does Keyword Stuffing a "Seo Trick" beneficial in 2013 ?

Keyword stuffing is an unethical SEO practice which leads to banning a website in search engine ranking. It is very old SEO technique which is still used by many SEOs. Though many SEOs are using keyword stuffing in smart way. Those SEOs might be lucky as their website not penalized in latest updates from Google. Keyword stuffing is   black hat on page SEO technique. Keyword stuffing occurs when a web page is filled with keywords in the meta tags, alt tags or in content of a web page. Keyword meta tags is not used by Google for ranking web pages. SEOs use repetition of words in meta keywords tag.I have analyzed many search queries for different industries and verticals in 2013. I have found keyword stuffing still works. I have seen may websites rank well just because they stuffed keywords in title, alt tags of images, title attribute of links and content. It is observed that not all website caught by Google’s anti-spam algo in the year 2013. I have seen the website which are very new with PR 1 or 0 are coming on top just because keyword stuffing in its source.- Title Tag is the most important element in on page SEO. Many SEOs are targeting title tag for keyword stuffing while Google Quality guidelines recommend using appropriate and unique title tags.
Keyword Stuffing in Meta Description – I have seen many SEOs put all the keywords in their meta description tag and Google shows these tags in its search result snippet. It looks odd to white hat SEOs.- Usually people stuff keywords in meta keywords tag. But meta keyword tag is not used by Google for its SERPs. Bing and Yahoo use meta keywords tag in their algos.- Still most of the SEOs using this technique. In the recent days I have checked so many sites they are using it. It is not surprising that Google has not banned these sites yet. As not 100% spammers caught by Google. But be aware and do not use keyword stuffing in image alt tags. - SEOs using keyword stuffing in content also. Mouse over div + java scripts based content on web pages that doesn’t make sense to the reader. For example a software development company writes content what is software development on its home page. It also writes content about SDLC, different software applications. But that content is used for ranking purpose only. Real users will only be interested what kind of software company develops, what are the key areas of those software applications or products. This topic is still not captured in many SEO blogs. As Search engines always suggest that page should have content, but that content really make sense to readers. I always prefer to have content which is read by visitors. Create content for users not for search engines. You can Stuff Keyword in Content but it should be in a well manner so that when visitor read your content it seems to be good for them. Not simply putting all the keywords without any sense. One thing while Stuffing the keywords also remember the Keyword Density, it should not be so high. You can also go to this post "Best Seo Optimization Techniques To Promote Your Website".
