A lot of testing has gone in to this list, and I feel it is the very best for auto blogging. If anyone can ad some more please do. I try to keep plug-ins to a very minimum, so here they are. WP-unique Extreme-SEO SEO-Booster-Pro WP-Robot Autoblog plug-in Web-Traffic-Genius-Pro All-in-one-seo-pack Easy-privacy-policy Google-sitemap-generator Pc-robottxt Rss-footer Sexybookmarks Statpress-reloaded Twitter-tools wp-followme wp-spamfree Yet-another-related-post-plugin
All-in-one SEO is not an autoblog plugin (regarding the subject of this thread) but is a good additional plugin that works together with Wordpress Robot. To more finetune the SEO part you can also install HeadSpace2.
Very weird list because some of them are not an automated plugin (yet another related post, all in one seo pack, twitter tools... (what twiiter have to do with autoblogging?)). I heard that WPRobot was the best for autoblogging if you know what is the meaning of "autoblogging".
Not saying they are all auto blog plug-ins, but these are the plug-ins I use on all my auto blog. They do very well. Once set up I do nothing but check big G.
Although its software rather than a plug-in, my vote would have to go to Carthy Studios ABS Autoblogging Software. Will bring in a complete feed (even from fragments) inc. images and uploads to "scheduled" and posts at a frequency of your choosing. The advantages are that you can manage & control 1000+ blogs from your desktop without having to log in to each blog individually, the fact that it works with WP and Blogger and also the fact that it will upload PLR articles from your hard drive and schedule those in as well. There is also an auto translate tool so you can pull content from other languages (and thus make it unique) or, another way of creating unique content, have it translate from English to, say, German and back to English All round pretty neat. Don't know where I'd be without it these days.
Replace all-in-one-seo-pack with headspace2 and you are good to go, the latter allows a more dynamic on-site SEO experience.
Get KeywordLuv Plugin this is a great plugin that allows others comment on your blog if they leave a valuable message. This helps your user experience as well as your quality content being indexed by Google. At the same time, it benefits the person looking to get a link back to their page. It's good stuff try it out yourself.
