WordPress, a very useful tool for blogging websites. It can be made more effective by using its plugins. Here I listed some important plugins for wordpress that make your work more  easy.

1. Gravity Forms

Gravity Forms is a great plugin for managing online forms. It has some extremely useful features including conditional form fields that allow you to show or hide a field or entire sections of the form based on a value selected in another field. It is also possible to pre-populate form fields using querystring, shortcode, function or hooks. It also offers the facility to schedule forms by assigning a start date and end date for when your form is live on your site.

2. cformsII Form Plugin

cformsII is a free form management plugin that can be used to set up contact forms on your WordPress site. It does not require any stong knowledge of PHP or codes. You can easily build forms in the WordPress admin panel, navigate to the page or post where you want to use the form and there is a button in the WYSIWYG editor that you click and up pops a list of forms that you have made. Just choose your form and it gets inserted into your page. Update your page and you the form is live.

3. NextGEN Image Gallery

The NextGEN image gallery is a great plugin to display a photo gallery, show several product images, or publishing a slide show. It is a fully integrated Image Gallery plugin for WordPress having a Flash slideshow option. Other features include a thumbnail generator, sortable albums, and a water mark function.

4. WP Super Cache

If your WordPress website is popular and has a lot of visitors, you should consider running WordPress Super Cache to enhance the performance of your website. This is because if you don’t cache your pages, then every time a visitor comes to your site, WordPress has to bring together many pieces of information out of a database to put your page together. Thus If you have more traffic, it can really become a problem. WP Super Cache stores a copy of each of the pages on your website so that after the page has been arranged once, WordPress simply has to keep showing the static html copy of the page to the users.

5. Google XML Sitemaps

The Google XML Sitemaps plugin automatically creates a site map for your site, linking all your pages and posts, and notifies Google, Bing, Yahoo, and Ask.com whenever you make any changes to your website.

6. All in One SEO Pack

With this plugin, your WordPress blog is automatically optimized for Search Engine by allowing you to enhance things like your page title and meta tags. With this plugin, you can customize almost everything.

7. Page Mash

With this management plugin, you can drag-and-drop the pages into any order you like, modifying the page structure by dragging a page to become a child or parent. If you have a WordPress site, with multiple pages, PageMash is very helpful.

8. WP Logic

The WP Logic plugin gives each widget an extra control field called “Widget logic” that control the pages that the widget will appear on. If you have a WordPress website that acts as both your main website and your blog, and you only wish to show your blog categories on your “posts” and not on your “pages”, you can do this easily with this plugin.

9. Wickett Twitter Widget

The Wickett Twitter Widget is a great way to get your most recent tweets on your WordPress site. It gets installed as a sidebar widget allowing you to specify the number of tweets that are displayed. Although there are many other Twitter related plugins available too, but this one is the best because of its simplicity and elegance.
