My company's website is running on WordPress. I've been asked to find an easy way to add custom meta description & keywords to the site. Of course, found an extension that easily allows this on the posts and pages. The end result - which seems to be acceptable - is a custom description meta tag and a custom keywords meta tag in addition to the site-wide description and keyword tags that are customizable within WordPress globally. I did a good bit of research and it seems like it's not detrimental to have an extra keyword or description tag but I was hoping someone else had experience with this or is potentially familiar with the benefits of doing this.
It's worth noting that the extra tags are not generated unless you populate the custom keywords and description per page. Thank you.
