Here is the list of top 10 WordPress plugins which I have setup on Blogs@DiGiTSS, why they are good and why you should install them if you're using WordPress Blog. If you use and choose them wisely these plugin will help you make most of your WordPress blog by making it more search engine friendly, will help you spread the word and to keep visitor busy on your website.
Google XML Sitemaps: It generates XML sitemaps for your WordPress blog automatically based on configuration you specify. It will help search engines like google, yahoo, bing or ask.com and many others who use Google XML sitemap format to crawl your website/blog. It is a kind of must have plugin for any WordPress blog.
All in One SEO Pack: This plugin provides out-of-the-box SEO for WordPress blog. You can specify different title, keywords and meta-description for any post. So that title of the post can be different than the meta-title under head tag which can help in SEO. As well as it will build custom keywords for post-lists by collecting keywords from each post. (For example home or any category list - it will collect list of keywords from each post and build a keyword list).
WP Super Cache: WP Super Cache is the best plugin if you want your posts to load faster as once loaded your blog-page will be cached as html file so that subsequent requests will be served by that html file only avoiding database query, which will improve the performance of your WordPress blog and let you serve more requests per second.
Similar Posts: This plugin brings list of similar posts for any blog post. It is highly configurable in terms of functionality and it can configurable by # of keywords used in posts or tags or categories etc. Similar Posts will help you retain your blog visitors on your blog for more time and reduce bounce rate. I am sure that once you'll install this plugin you'll observe your bounce rate going down with your analytics tool.
WordPress Popular Posts: Show your most popular posts on your blog, where visitors have commented on your posts. Just need to paste a function call and it can be placed in any of the text-widgets of your WordPress blog.
Akismet: Akismet is quite possibly the best way in the world to protect your blog from comment and track-back spam. It keeps your site protected from spam even while you sleep. If you're using 3rd party comment integration like IntenseDebate or disqus - the one which we have used for Blogs@DiGiTSS you may omit use of this plugin. But for plain comment form it's one of the best protection against the spammers.
IntenseDebate: IntenseDebate Comments enhance and encourage conversation on your blog or website. Full comment and account data sync between IntenseDebate and WordPress ensures that you will always have your comments. Custom integration with your WordPress admin panel makes moderation a piece of cake. Comment threading, reply-by-email, user accounts and reputations, comment voting, along with Twitter and friendfeed integrations enrich your readers' experience and make more of the internet aware of your blog and comments which drives traffic to you.
FeedBurner FeedSmith: FeedBurner let's you publish your feeds and helps you keep track of them. Originally authored by Steve Smith, this plugin detects all ways to access your original WordPress feeds and redirects them to your FeedBurner feed so you can track every possible subscriber. FeedBurner is now acquired by Google as Google is the company who likes to keep track of everything you do over the Internet.
Conclusion: Do not end up installing all the plugins and choose your plugins wisely. We have installed Webiya and Meebo-bar respectively for social interactivity but later on removed that as a trade of to improve the load-time of our blog. Recently there are good improvements with Webiya and we might turn that on again soon. Other than discussed plugins there are plenty of social-bookmarks plugins available which can help you have your visitors bookmark your website/blog on their favorite bookmark website but that's deal you need to take care very precisely. While adding all these plugin we still want our site/blog to look decent and not cluttered or jammed with too much stuff. One of such plugin is AddToAny: Subscribe Button.
Also Facebook Like button is a must have tool now a days since it is launch and it's wise decision to place one on ours. Like us on Facebook if you liked this post.
