In conclusion, only 23% approve and thus even with some unfinished business optimization. Which does not fail and, as we have seen, affects 100% of the subjects analyzed is as follows:

«Delete blocking JavaScript and CSS visualization of the content of the upper half of the page».

This problem, which is recommended remedy, not only affects the speed at which loads the web but how the various elements are loaded, so you should have it well controlled.

Not all pages use the same time to load and are optimized equally. So we wanted to also analyze the specific performance of pages, such as a category and a blog.

Test on category pages

Desktop category pages After analyzing the issues, the conclusions are as follows:

Only 23% approve. 77% suspended. Specifically, 50% needs improvement and 27% have an optimization poor

Test in Blog Entries Desktop

The results of the analysis of blog entries or post reveal that here there are problems even greater as to the performance and loading speed:

to 86% does not pass the test PageSpeed. Only 14% approve. 52.5% «needs work» and 34.5% has a poor optimization

Only 4% approve, while 96% is suspending, but in this case 43% «needs work» and 53% have an optimization «poor

Test Mobile Blog Entries

Here the problem becomes even worse.

100% of blog entries of the topics discussed suspended in mobile. 38.5% «needs work» and 61.5% have an optimization «poor

But this does not stop here. Now let’s look at more specific issues affecting performance.

Optimizing images prominent or thumbnails

96% of the topics discussed are issues related to the optimization of images, which directly affects the performance of the web and loading speed

¿ this what happens?

Many themes incorporated into the sidebar or in different sections related entries links to web pages and these links are accompanied by images or thumbnails.

The problem more often than the actual size of these images is much greater than actually shown and weigh too much, which causes the charging time automatically resent the website totally unnecessary.

This also can check with the PageSpeed ​​tool we’ve seen before:

Mala code optimization

75% of WP themes analyzed do not take advantage of the native functionality of WordPress, which are many , and instead have a high dependence on additional features, shortcodes and mandatory plugins to function properly, which directly affects the performance and load time

the basic problem here is poor or inadequate optimization of the code.

unnecessary functions and non-native WordPress

Many themes have no code optimization best and, instead, rely on additional functionality, resent greatly the loading time of the web, as the HTML that is generated by these external programs is not optimized and is adding unnecessary layers in the code.

Thus, rather than take advantage of the many native WordPress functionality, incorporate new ones are added to the first and the web causing heavier and more.

A clear example of this are programs like Visual Composer, TagDivi or Page Builder, which incorporate a large majority of themes to offer greater customization of the design but at the same time, add extra functionality to WordPress that have an impact on the loading rate.

Remember: The design is fine. We must take care of it. But is not everything, especially if what is at stake is the performance of your website and your users’ experience. Keep it simple!

Unit shortcodes

Similarly, many issues have to run correctly excessive reliance on shortcodes to give access to unnecessary functions or could provide good code optimization.

external plugins required

Many themes require the installation of certain external plugins to access features and basic configuration. If not installed, the web will not work properly.

Yes, plugins can greatly facilitate our lives, but also cause our web weighs more because of the blue and the charging time will suffer. At the end everything adds up.

In many cases, these mandatory plugins really are unnecessary and could be solved with programming code in the theme for no more lugging our web.

Conclusion: When choosing a theme, look good on the purchase page if, to function properly as promised, the subject needs this kind of elements and functions outside that can directly affect the weight of your website and, therefore its charging speed. From there, it appreciates what most deserves your money’s worth and what most interests you sacrifice.
