We posted many blogs with some keywords after some time keywords has changed of my website so my blogs are waste. I want know any how can i change keyword and links of my blogs without any problem.
I'm sorry, your question is not so clear. You want to know how you can change the keyword and links on your site/blog? You can go into each of your articles and rewrite them so that they contain your new target keywords. As for the links, do you mean your page/post URL? If so, you might want to do a redirect from the old version to the new. This is because those old links would probably have been indexed already and you've probably created backlinks to them too. So to make it easier, use 301 redirects. Hope that helps. Have a good day!
