i was searching on the internet. And found out that now meta keyword is not important for Google ranking. Now i am confused that Search engine like Bing take meta keyword for ranking or not??????????
I can assure you now Google now do not tracking the meta keywords for sites/blogs except news keywords for news sites/blogs. But Bing still monitor the meta keywords for ranking point.
Meta keywords are probably of minimal importance at best. However, since it takes only about 30 seconds to add meta keywords to a new page, I still do it, figuring it can't hurt and might help with some search engine(s).
Back then, It was effective but now Google ignore it and has no effect Its too late to let you know about this. Google is focusing on site's content that are engaging and generates conversation from the targeted audience. Bing and Yahoo still consider meta keyword as one of their ranking metrics in the search results.
I think, bing also does not use meta keyword as ranking factor like Google. Keyword in title and description is still useful.
