Recently I saw some "how to" articles about putting the meta keywords in each Blogger post individually. According these articles, you have to put some code many times, e.g. if the blog contains 100 posts, the code must be added 100 times. Please see the instruction: http://goo.gl/zB3lKG
I am afraid this trick might be risky, because the template will be overloaded by adding this code many times.
Is this method is still necessary, given that there is now an ability to add descriptions in the post editor?
