Many elements affect your website’s speed, including technical tweaks only a developer would love. The good news is there are basic steps a novice can accomplish which go a long way to faster performance.

Before listing these 5 top website speed optimization steps, you should know the biggest factor is a fast and secure host. All your tweaks cannot overcome a bad host. With that in mind…

Top 5 Tricks to Speed Up Your Website

1. Optimized Images

The most important site optimization is to reduce the size of your images. Images can be displayed at any size, but the image file is first loaded and THEN resized. This wastes computing capacity because images are only reduced after loading.

The solution is to ensure your images are already in the desired dimensions—the optimal file size—and also, to compress your images. In general, images should not be larger than 1920 x 1280 pixels, with a file size under 350kb. This single step can do more for website speed optimization than anything else you do.

2. Minimize HTTP Requests

Every file on your website is downloaded through a separate “HTTP request” from your browser. The more files you have, the more HTTP requests are needed … and the longer it takes for your site to load. Eliminate unnecessary files or combine them when possible. One quick fix is to combine multiple CSS stylesheets.

3. File Placement

It is generally optimal for CSS stylesheets to be included at the top of the page (header section), with scripts at the bottom. This is because CSS loads progressively, while scripts block parallel downloading.

4. Minify CSS and JavaScript Files

Inefficient loading of CSS and JavaScript files will slow your website down. There are two main ways to minify: by compressing files into one, and by deleting white space and making the files themselves smaller.

5. Make JavaScript and CSS External

CSS and JavaScript files may be inline and part of the document, or referenced in an external file. These files are cached by the browser, so externally linked files typically mean faster pages. Make sure your CSS stylesheet and JavaScript files are linked in the header of your document.

Wordpress Speed Optimization

If you are working on WordPress speed optimization, a caching plugin such as W3 Total Cache, or WP-Super-Cache can make a real difference. Also, if running Wordpress, be sure to deactivate and delete any unnecessary plugins … remembering the rule is to never use more plugins than necessary.
