There are quite a few plugins available for WordPress that will tweet out new WordPress posts automatically when they are posted. By having your posts automatically tweeted you have one less thing to worry about in the day.
Even though there are auto-tweet plugins aplenty, none that I have found is quite as extensive as WordTwit Pro. This plugin gives you pretty much what you need to share your links more effectively and saving you more time.
Scheduling Multiple Updates
WordTwit Pro will offer you the option of tweeting your post to the world multiple times of the day. You can choose, on a post-per-post basis, how many times you want it to be tweeted out and, if more than one, how long time that should pass in-between. You can also have your tweets delayed from the start.
It would be thoroughly useful if WordTwit Pro allowed you to set a default setting for this in its settings. Currently, you can only set this per post, which is slightly more time consuming than ideal when you usually use the same time settings for posts.
Tweet to Multiple Accounts
While many freely available plugins allow you to tweet to one account, fewer allow you to set-up more than one account to tweet to. By default, all accounts are selected for each post but this can be customized per post in the WordTwit box.
Even though I typically publish to all accounts that I select, I could see a setting similar to what should be there fore multiple updates. This would be a setting that allowed you to change which accounts it tweets to by default. Maybe there is an account you only occasionally use?
Hashtagging, Tweeting and Short URLs
As you would expect any auto-tweeting plugin to do, WordTwit Pro manages hashtags easily and will of course allow you to customize the tweet for each post.
The plugin has settings that lets you add tracking links for Google Analytics, as well as choose a URL shortening service of your choice and also use the APIs of these service providers. This means that if you have a custom URL set up with bit.ly, WordTwit pro would use this in your tweets.
WordTwit Pro is a paid WordPress plugin but at $39 for a single site license, it is very fairly priced. If you are a developer, you may get a 5 site license for $69 or opt directly for a Pro Unlimited version at $99 that gives you installation rights on an unlimited number of sites, including WP MU installations. There is a free version available which provides a much limited feature-set.
If you need to be able to tweet to multiple accounts or want the added comfort of being able to tweet automatically multiple times of the day, WordTwit Pro is a good fit for you. Even though it does lack some default settings that would highly improve the plugin, it still is a very nice plugin as it is that is far superior to other auto-tweet plugins currently available.
