JavaScript has gained widespread popularity in
modern website development, enabling dynamic data loading and the integration
of captivating effects into your blog or web pages via AJAX. However, the
trade-off for these benefits is not insignificant.
Frequently, you'll find yourself reliant on hefty JavaScript
libraries, which can substantially increase the size of your web pages. This,
unfortunately, leads to extended loading times, a universally disliked aspect
that can adversely impact your site's SEO.
If you've analyzed your blog's performance using tools like
Google PageSpeed Insights or GT Matrix and identified this issue, here's how to
address it.
In Google PageSpeed Insights:
- A
site speed between 0 to 49 indicates a "Red Signal," signifying
slow loading.
- A
speed between 50 to 89 results in an "Orange Signal," denoting
average loading speed.
- A
score of 90 to 100 receives a "Green Signal," indicating fast
loading.
Don't fret; you can resolve this issue by simply replacing a
code snippet to improve your blog's page speed. Here are the steps to do it:
Step 1: Log in to your Blogger blog, select
"Template/Theme," and click on "Edit HTML."
Step 2: Search for "ajax.googleapis.com" in
your code. You may find either one or both instances if you've added them to
your theme.
Step 3: Select or delete the entire jQuery script and replace it with the following script:
<script id='script-batch' type='text/javascript'>
(function(d){
var js = d.createElement('script');
js.async = true;
js.defer = true;
js.src = "https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js";
d.getElementsByTagName('head')[0].appendChild(js);
}(document));
</script>
Step 4: Click "Save" to apply your
settings.
Now, return to Google PageSpeed Insights or GT Matrix and
recheck your blog's page speed. You should notice a significant improvement in
loading time.
