Shopify does some minification natively, but it still leaves opportunities to improve the page-load speed.
This is because Shopify does not minify the liquid files which contain the theme settings. And that’s where SpeedBoost Ninja comes in. Our app minifies the liquid files to improve your store’s page-load speed.
However, your store may have some files which cannot be minified due to the code structure, in this case, SpeedBoost Ninja skips those files. But ideally your store’s code should be clean, other third-party apps or customizations are usually the cause of bad code.
However – there are 2 cons:
2) Your Google PageSpeed Insights score may go down – this does not mean that your website has become slower.
Google scores your site for each of the optimization options, for not obeying the recommendations Google takes off the points.
So, on one hand, you get fewer requests to the server, but on another, you get more time render blocking. However, the overall page-load time may be lower because of the image compression and because there are fewer server requests.
In cases when you have the initial score +/- 50, and after you run the app you did not see significant improvement, you have to check following:
Were your images too big? We are optimizing your images very carefully so as not to lose too much quality, so if you had super big images, they might not have been optimized as much as possible. If your images are ok, try to restore your theme from the backup and run the app again without concatenation.
If nothing improves, your theme might not be coded to best practice standards, or maybe another third-party app is causing the issue.
Why the score goes up and down sometimes
SpeedBoost Ninja shows the overall score from the Google PageSpeed Insights tool.
Unfortunately, Google doesn’t give us a breakdown of how the score is calculated. There are many things which can influence the score:
- The connection status of the Google servers, even Google servers may have some issues from time to time.
- Any connection issues or traffic spikes with Shopify’s servers.
- Technical issues with the Shopify servers (i.e. GZip being turned off for a short time by Shopify’s tech team.)
- Technical issues with external services; modern themes use a lot of external services. which take time to load, and all of them are influencing your score. For example, we’ve seen a lot of issues with GetResponse, sometimes it takes up to 15-secs to load, which will push your store’s score into the red zone.
How to determine if your store has these issues:
First, re-run the optimization in 1-2 hours, usually Shopify/Google will fix any server issues pretty fast, otherwise they notify that there is an issue on their side. However, some of the third-party services may have the permanent issues (like GetResponse does), in this case you need to get technical support to review your website.
