Any Cons to Using Wordpress Plugin: "wp cache"

[imbckagn]

I am trying to figure out if the Wordpress plugin "wp cache" is going to have any negative SEO effects. From what I under stand it creates a cache of a post/page and serves that to a visitor.

I am concerned that this may cause duplicate content issues or have a negative impact some how.

No, it isn't duplicate content - it's the same content with the same URL. Only you and the server know that the source is different

This may be a bit nit-picky, but the only thing I've read that may play into SEO issues is that, by caching your pages, you may run into some freshness issues IF you forget to periodically clear the cache to allow pages to be updated with the latest comments, etc.

You probably can remove this consideration if you are running a cron job that clears/updates the cache nightly, etc.

I'm not familiar with that particular plugin, but in principle you can run a cron job as often as once an hour (or every five minutes if you want, but at that point, why cache?) if you like and keep things fresh. If you aren't getting frequent comments, it will fire, find nothing, and quit. No massive server load. That depends on the design of your caching and like I say, I don't know that particular plugin.

Thanks for the feedback. I'm still on the fence because this is for a very popular website. It would kill me if it somehow messed up SEO...

Would it kill you if you got a Digg and your site couldn't handle the load and went down?

Every SEO I've heard speak at Pubcon about using WP recommends implementing some sort of caching.

When you say "popular", how many comments do you get per day?

If you use the Super Cache [wordpress.org] plugin instead you can set the refresh rate and the plugin will refresh the cache on it's own.
