The new update of the free version of CommentLuv contains some great features.
The two new features I really like are the ability to link to Author or Category URLs as well as specific posts and the new spam prevention feature.
In the new version you can choose to have the link in your comment go to a category page instead of to a specific post. So if you are commenting on a coupon site you can link to your coupon category, or if you are commenting on a software site, you can link to your software category. So your links will be more relevant to the site you are commenting on.
That can make a huge difference in whether people choose to click on your link. After all if they are on a coupon site they probably will want to check out links for coupons.
The new spam prevention lets you choose to have CommentLuv only accept comments that have a last blog post URL that matches the URL of the site. This can prevent spammers from putting links to sites that only look like they come from a certain URL.
The new version also has better error reporting and is more efficient.
I love this plug-in and have had it on my blog from the beginning. And now it is even better! Try it out.
