Theme migration huge performance jump
Here is an example test before and after we made some site changes. We migrated a site from theme published in 2006 to a more modern theme and spruced up the home page navigation.
The overall score went from 71 to 76 so the old site wasn’t that bad. However the details show some astonishing outcomes. The overall Accessibility went from 74 to 96 and the SEO score from 69 to 100.
This was quite remarkable. After the first day, the site owner also sent me an email that when he searched his name on Google, he saw for the first time that his own website actually showed up before any of the social networks or news sites, which normally have a much higher authority that any single topic site. Once can not know for sure but with the SEO value going from 69 to 100 percent, I definitely wasn’t surprised by that outcome.
After a week or so, the site owner realized that we didn’t bring over the advertising he placed on his older site. When we added Google AdSense areas to the footer of the site, the performance went way down again. How disappointing….
So it’s not only important to measure the performance of your website and each single page, it also is necessary to monitor the performance over time, or at least test is again, after you make significant changes or start using 3rd party systems.
Image Lazy-Loading coming to WordPress Core
The biggest problem with page speed is image loading with the site. They are most of the time the largest files and many content creators don’t optimize images before upload and employ all kinds of additional plugins.
This month, WordPress core committer, Felix Arntz announced the feature plugin for lazy-loading images out of the box in core. Later this year, it is supposed to be merged into WordPress. We tested it on one of our non-optimized sites just be installing it and measuring before and after.
The changes in speed were quite remarkable! It went form 19 to 35 on the Performance and from 79 to 87 in accessibility.
