Probably what makes blogs different from regular websites the most is the ability to add comments on a blog post. Although not always, these comments are often turned into an interesting discussion, and the blog writer or reader gives out more information regarding the topic at hand. Unfortunately there are plenty of spammers using commenting features to leave their traces. They usually leave a completely irrelevant comment with a link back to their site.
To manage comment in WordPress blog we start from the “Discussion” tab (Settings >> Discussion)
A few explanations that I think necessary:
Attempt to Notify Any Blogs Linked to from the Article: We are often mentioning other blogs / website on our post, this option makes our blog sending a notification to another blog we are mentioning. This can slow down the posting process a little since it takes time for our blog to notify the other blog.
Allow Link Notifications from Other Blogs (Pingbacks and Trackbacks): The opposite of the previous option, this time it is the other blogs that are trying to let is now that they are mentioning us.
An administrator must always approve the comment: It is a good idea to check this box, so we can carefully select which comments we want to appear on our blog. Also an auto approve blog is like an invitation for spammers to drop down their spam links.
The other options are should be easy to understand.
After we are satisfied with the basic settings, we can continue to “Comments” tab
Here we can see all of the comments on our blog. If we want to do an action to one comment, hover the mouse over it, then choose what kind of action we want (approve or unapprove, reply, quick edit, edit, mark as spam, or delete it.) To apply a certain action to several comments at once, check the comments you want to apply the action to (check box on the left side of every comments) then choose the action from “Bulk Actions” drop-down box above.
Finally we can set the comment feature in a specific post.
In “Add New” tab (“Posts” >> “Add New”) notice the discussion tab at the bottom of the image above. We can allow (or not allow) comments and trackbacks and pingbacks specifically to the post / page.
Personally, I would advice to manage comments carefully. Good comments can and will add great value to your blog, while spam can harm its quality. If we are too strict about allowing people to leave comment, then they probably choose to be silent even when they have good information or opinions about the post. Manage this feature wisely; use it to your advantage.
Click a post title to edit just that post.
This interface also provides some very powerful batch-management capabilities, letting you change the categories, tags, authors, or publish status for hundreds of posts at once.
