The Significance of Website Speed

Speed is an important factor that needs to be taken into consideration both when improving SEO and building your infrastructure.

But since it’s a complex and technical issue, you need to be well versed in different aspects. Some of the vital factors that need more attention are mentioned in this piece.

How Are Web Pages Loaded?

On the surface, the user opens their browser and enters a URL. When they enter a URL, a DNS request is sent from their end.

This issue directly pertains to the domain and hosting provider.

For example, a hosting provider like GoDaddy stores all the files and information locally. Now things start to get interesting; DOM starts loading all HTML, CSS files, and also JavaScript. But it rarely runs all the necessary scripts or loads a web page.

DOM requests additional resources from the server to run everything correctly. This is where everything starts going downhill culminating in your website loading very slowly. This short description might have helped spark a few ideas on what things you could do to improve your website.

Factors That Slow Down Your Site

So, who are our first suspects?

• Images are the primary cause of reduced loading speeds most of the time. Large images in particular take a long time to load
• Hosting Issues
• Plugins, applications, widgets and all third-party scripts could reduce your website’s loading speed
• Badly optimized themes
• Multiple redirects are also impactful in terms of your website’s loading speed
• The way your embedded JavaScript codes are written is also an important factor

if we consider all these to be present on your website then this chain effect will significantly reduce your website’s speed. So this post will cover certain resources you can use and metrics you should keep an eye on to significantly optimize your website speed.

Website Speed Testing Tools & Other Resources

The first resource listed here is Google Tool and the Google Suggested Insights section. You may find it interesting to know what metrics these tools actually analyze especially when testing speed or what user metrics are taken into consideration.

We need to familiarize ourselves to an extent with how these tools work otherwise it will be much harder to figure out why your website’s ranking is stuck.

We know that Google prioritizes websites that load faster. Their proposed estimate is somewhere between 1 and 3 seconds.

So set your sights on that timeframe but if it’s possible to reach a faster loading speed, go for it. We’d also suggest taking a look at your competitors’ websites and analyzing their website’s speed to set a bar where you can judge your own website.
