SMu Manual DoFollow


This plugin will set all Trackbacks and Pingbacks automatically to DoFollow Links.

The user comments will get after X comments from a unique mailaddress automatically DoFollow status. All other comments have NoFollow, except the Admin enable manually the DoFollow Status. The status which is set manual (if DoFollow or NoFollow) will overrides the automatical process. So, you have the control if someone gets sooner the DoFollow status, or never maybe. Of corse, the automatism can be disabled to do the hole work manually.

You get an support automatism, that you don’t need to check daily, but have the full control power.

Additonal this plugin validated all DoFollow URLs and will notice if there are broken links. Broken Links are very bad the Rank in the Search Engines (SEO).

Need this plugin a lot of performance?

This plugin has 2 diffrent functions.
The First, two diffrent Link functions: the automatically and manually-set status.
First, the Plugin checks if there is a manual-set status, which needs nothing on performance, because its connect to a very small database which contains small data.

If there is no manuall set status, the automatism is checking the comments table for the amount of comments of the user. If you have a very large number of comments, you can feel a very small decrease. But if you really have more than ~20’000 entries, you will choose a Cache Plugin anyway.

The Secound is the URL Validater. This can made manually, via Cronjob or automatically over wp-cron.
The manually needs a little bit of time but will not decrease performance for the readers, also the cronjob.
The best way for big blogs with a hugh amount of links is the cronjob.

This Plugin can be used with any Cache Plugin which caches the database querys and objects. As example the W3 Total Cache or WP Super Cache Plugin.

Is there a database modification?

Yes, there is are 2 new tablse added in the wordpress database with the name wp_man_dofollow and wp_man_dofollow2. This Databases contains the information about manual set DoFollow/NoFollow Users and the time/status when the link is checked the last time.
The first table wp_man_dofollow content is a mailadress and an ENUM(yes,no) value.
The secound table wp_man_dofollow2 contains the URL, Status and Lastcheck time.

Both databases doesn’t need a lot of space and performance to generate the needed functions.

Are there any known bugs?

No, otherwise I would fix it 🙂
