Add Post Footer
The Add Post Footer is very useful in helping you cross sell products, a free eBook to encourage readers to subscribe or other top articles that are related to your post. It allows you to enter HTML code into the footer of every post you write and is very simple to use.
All in One SEO Pack
As you can see from the name of the plugin - it's an all in one SEO pack that assists each post in your blog to be "search engine optimised". You can either leave your header, meta tags and description of your post just the way they are when you publish, or you can fine tune them to be more specific to keywords you want to use for search engines. I've found at times I wanted to add additional keywords and change the description of my post instead of having the default Wordpress summarised description. A must have plug-in for serious Internet marketers!
If you're on Twitter and want to save time twitting - the Bird Feeder plugin will automatically feed your most recent posts in the format of: [your message] [post title] [short url] to Twitter. It's great because you won't have to double up by copying and pasting your posts back into Twitter or be on Twitter 24/7 (if you're not already).
This little gem, the FeedBurner FeedSmith takes your blog's feed and redirects it to Feedburner. It's better branding for your site and you won't have FeedBurner's domain name showing when a reader clicks on your RSS feed button, e.g. feeds2.feedburner.com/internetbusinesspath becomes internetbusinesspath.com/feed. For more detailed instructions.
Google XML Sitemaps
If you want to be found on Google, then Google XML Sitemaps plugin is a requirement for your blog. This plugin creates a compliant XML sitemap for the Google bots to crawl your site and it will help your blog achieve higher rankings if you want to be found on their search engine. Once you've install this plugin don't forget to hop onto Google Webmaster Tools to let them know you've got a sitemap for them to crawl, otherwise Google won't know.
Max Banner Ads
Monetising and profiting from your blog couldn't be any easier. If you have advertisers and want a very streamline and easy way to insert their ads onto your blog, then Max Banner Ads is the plugin for you. I use this on my blog and it's saved me a lot of time. It's easy to use and can be very profitable for your blog.
RSS Feed Signature
The RSS Feed Signature is another great plugin to use within your RSS Feeds. It simply adds a customised signature to any RSS Feed that goes out to your subscribers. If you are keen on increasing your subscribers, I would suggest installing this plugin and add a "free eBook offer" to your RSS signature. If you subscribe to my RSS Feed you'll see the link at the bottom of each feed to take you to the free eBook offer. You can read more about how to download your free eBook from the RSS feed.
Top Commentators Widget
This plugin allows your blog to display a user who has posted the most comments. The Top Commentators Widget shows other readers your highest commentator and will encourage people to find out who they are by clicking on their name. Also the highest commentators websites will be linked automatically onto your blog and can increase your search engine rankings as well. Therefore getting you more traffic and more comments all at the same time.
What Would Seth Godin Do
Most people would know Seth Godin as his name is associated with Internet Marketing Guru. The What Would Seth Godin Do plugin simply displays a welcome message on your blog for first time and returning users. It may ask them to subscribe if they're a first time user or thank them for coming. It's a great tool to have to create the "experience" for a user coming to your blog.
Wordpress Simple Paypal Shopping cart
If you're like me who offers advertising on my blog and needs a simple way for advertisers to pay you, then the Wordpress Simple Paypal Shopping cart is an easy plugin to install and use. It allows anyone to pay you using Paypal which is used by millions of people worldwide and can save you time having to respond to advertiser's email with your bank account details and so forth. The plugin has functions to let you add a "Add to cart" button and creates a shopping cart module when the advertiser or user decides to pay you. It will then redirect them to the Paypal website to pay. Very simple to use!
If you haven't tried any of the plugins above I would highly recommend adding them to your blog. So give it a go!
