Wordpress Plugins
In setting up my Minecraft 1.8 Seeds blog, I've used a few plugins to help me configure and manage things like SEO, site performance, analytics, etc.
To help with SEO, I've installed the SEO Ultimate plugin which I've found tremendously helpful for customizing keywords and other metadata, as well as helping with tracking down 404s blocking sections from being crawled by robots. It even added an AddThis widget to all my posts, which was very convenient.
I've also been working on setting up the W3 Total Cache plugin after noticing that Google Webmaster Tools noted that my site is "slow." It took some reading but I set up the plugin to use a PHP accelerator (I chose APC because it was easiest to install); use Amazon S3 as a CDN; minify my HTML, JS, and CSS; and set up Apache to make the best use of browser cache control headers. I am having some trouble with GZipping minified CSS, however, so I have that disabled for now, but it has already sped up my site quite a bit. Hopefully this will improve my Google rankings.
I also have a few other minor plugins such as Google Analyticator for including the Google Analytics script, and this silly Minecraft Block plugin which I set up to display a bookshelf block on my page with a link to the Minecraft Wiki. In Chrome, it actually uses CSS animation and spins!
I'm working on a new theme for the site now and once that's done, I might check out some more plugins for things like Facebook or Twitter integration. I'm also working on a custom version of my Skedjulator plugin, which should help with displaying the list of seeds on the site.
