You are loading some JavaScript code twice. Try removing the 3 consecutive lines:

Code:

<SCRIPT language="JavaScript" src="actiniccore.js" type="text/javascript"></SCRIPT>
<SCRIPT language="JavaScript" src="actinicextras.js" type="text/javascript"></SCRIPT>
<script type="text/javascript" src="Act_sections.js"></script>

The first 2 lines get loaded later and the 3rd line isn't being used at all (it comes from a redundant JavaScript based menu).

Hi, Helen.

I ran a quick speed-test on a couple of pages (Home + a catalogue page) and the result was not to bad apart from the mobile version of the home page (which scored 60). Personally, I would not be too concerned at any score around/above the 70 mark. It is more important to optimise for mobile as this is where the real delays are; broadband has largely removed delays for the majority of desktop sites.

As to your questions, if you follow the links from the Page Speed tests the recommended sites are okay. Alternately, if you use Firefox web browser you can install 'Firebug' which will provide similar Page Speed tests (Desktop only) and allow you to save minified (compacted) to your PC.

The note of caution I would add in using Javascript minifiers is that they can sometimes cause syntax errors in your compacted code. Run them through a validator before using a minified version and always keep an uncompressed backup.

My last comment is perhaps the most important. You will be able to opitimise CSS delivery within the Sellerdeck environment - effectively, this means placing code 'in-line' on each web page. However, I would be interested to hear from Sellerdeck whether they advocate minified .JS (Javascript) files on live sites generally. I can't see any reason why live sites don't use these as standard but what is the official view ?

You can also look at using CSS sprites and use positioning so you are only calling a single image to have multiple functions.

It is also worth looking at the server cache details in the .htaccess file so people who do not browse incognito can load from cache rather than from scratch.

Thank you very much for the suggestions.

I have downloaded Firebug so I will have to fiddle and see how I get on (saving everything in triplicate beforehand of course...)

There are online tools for compressing css which basically create code shortcuts. Create a copy and rename your original actinic.css in case the new compressed file makes a mess of things as I found fonts do not size correctly in a few cases.

Have a go with http://www.minifycss.com/

Just used this to reduce javascript file sizes resulting in notable Google Performance Improvement
https://javascript-minifier.com/

It all seems to be working so far.
