Hi, every week, i always write market forex outlook. Should i make new post or should i update last week post?
Do not make new URL for regularly updating content.
Just use one generic one and keep updating its content everyday. For your site, showing Last Modified Instead published in the entry meta can be helpful.
I think making a new post is a better option if the weekly updates are like 100-200 words different from last week. This allows you to add unique content if you follow new post every week approach.
If new updates are just minute changes, you can update the same post.
