1. AddThis
What started as a simple tool to add social sharing buttons to a site has grown into a one-stop shop for website marketing and conversion tools. To get started, simply insert a few lines of code into your website, and then you can control which tools you use from inside your AddThis.com dashboard—no need to go back into your site and update the code whenever you make a change. Keep visitors engaged on your site for longer by using the “recommended content” tools. Encourage email signups and increase your social shares and followers, and better yet, track these stats within AddThis’s analytics.

2. Wordfence
Staying on top of the latest cyber security measures these days is no small feat. Wordfence, a free WordPress plugin, helps make that load a little lighter. Wordfence provides firewall protection, locking out potential hackers, verifies your source code, scans your site for malware and repairs damaged files. The plugin encourages strong passwords for new users, and even tests existing passwords for strength. The Premium version allows for two-factor authentication, one of the most effective ways to enhance WordPress security.

3. Wufoo
Creating forms used to mean hiring a developer, but with Wufoo’s intuitive drag and drop form builder, you can create and add a form to your site in minutes. Use “rules” to make your forms dynamic—i.e. showing or hiding specific form fields or emailing the user based on his/her selections. You can even collect payments from users when you upgrade your account. Wufoo makes it easy to create contact forms, surveys, registration forms and more, and even integrates with other services such as Mail Chimp and Saleforce.
