WordPress plugin to reduce HTTP requests
The main idea behind this is to make your site faster to load, and more responsive. This way, not only will your visitors be happier, but you will also improve your Google position since load speed is a ranking factor.
There’s an excellent article about reducing HTTP requests on Yoast, so I won’t attempt to rewrite it, I’ll just comment on the technique from my point of view. I suggest you read the Yoast article, too.
Basically, what you want to do is to reduce HTTP requests your WordPress site makes. What does this mean?
I’ve been using BWM plugin to get that effect. There are other plugins that do the same, most famous probably being the W3 Total Cache one. It also does way more, so in case you’re not familiar with it, do check it out.
