SEO Search Tag Tagging 2 settings and caution

Are you using this plugin? If so for how long? Maybe you can share your settings. I used it 7 months ago on some autoblogs but all were deindexed. Im planning on using it on unique content sites and without indexing the search pages (Adsense TOS says not to index search pages).

And if there is another alternative to this plugins you can share also your thoughts!
