Comment on Stallion WordPress SEO Plugin by SEO Gold Services.
The Stallion plugin default settings do not prevent the indexing of any user generated content, they are the safe settings that if a user activates the SEO plugin and never looks at the settings page it won’t cause any SEO harm.
If I set the recommended settings as the default plugin settings pages like the monthly archives would be de-indexed.
I’ve set it that way because a plugin shouldn’t make that sort of decision for a user without their input. They should understand what a setting does before accepting it.
I can’t think of any SEO benefit to having monthly archives indexed beyond a basic sitemap (Categories and/or Tags are better), but a user might want them indexed for other reasons.
The Author archives again have no SEO value on 99% of WordPress sites, but if a site has multiple authors and those authors are popular de-indexing them may remove relevant SERPs to their usernames. Most WordPress blogs don’t have multiple authors, but if I assumed this it could damage some sites.
The Category and Tag settings are based on how you use them, some sites you’ll want them both fully indexed, others only one set, those settings definitely needs user input.
If you run a lot of WordPress blogs and don’t want to mess around with the settings (just want to activate and it’s setup as you want it) as long as you upload the Stallion plugin using FTP or the plugin installer (when you upload a zip file) you could edit the Stallion plugin file stallion-wordpress-seo-plugin.php and give it new defaults.

The recommended settings (I use these settings on most sites) would be:
