The same rules apply to Unbounce that do to anything on the web. If you google “how to speed up your website” you’ll get tons of tuts, posts, etc, that basically all have the same to do list:
- Minimize HTTP Requests.
- Reduce server response time.
- Enable compression.
- Enable browser caching.
- Minify Resources.
- Optimize images.
- Optimize CSS Delivery.
- Prioritize above-the-fold content.
… and they all work!
But, Unbounce is “cloud” software. We do not have control over a lot of these elements. We cannot access the core code of our LPs. There’s a lot happening under the hood we can’t see and a lot of what we can see we cannot do anything about.
Really it comes down to the basics:
- Image compression
- Minimize your scripts
- Minimize your CSS
- Minimize your copy
- Minimize embeds - this really slows Unbounce down. Not just video but custom forms as well or other 3rd party code.
- Keep your LP short and to the point - after all it is an LP!
Personally I think Photoshop does a really good job if you know how to use the optimization tools. That is how we do it.
I do like some of these tools - TinyPNG, Optimizilla, Compressor.io (already mentioned above) … there’s a great list here.
A CDN, when possible, is always of benefit.
On a final a note I agree with @Joe_Savitch speed is not always a factor, especially if your pages are already fast. If you’re page is slow - you’re doing something wrong
On a side note: I have seen slow pages still produces high conversions. It really depends what is slowing the site down.
