JavaScript SEO-Friendly Checklist

Meta Tags
Your title tags and meta descriptions are the first things your website visitors look at when they see your website on Google. You can’t have just anything there. You need to tell them everything they need to know about who you are, what you do, and how you can help them within the seconds they’ll spend glancing at your site.

It’s essential for your website SEO that you have meta tags that display properly without being truncated, contain your target keywords, and help your user understand what’s on the web page. Give your users a reason to click on your search result, visit your web page, and see what you have to offer them.
Mobile SEO Optimization
When your visitors check out your website, they’re probably doing so on their smartphones. Over 52% of all web traffic takes place on mobile devices like smartphones.

Google made the switch to mobile-first indexing in 2019. That means when Google ranks your website SEO, they will look at the mobile version first.

A web experience optimized for smartphones and JavaScript is what users and search engines both want. It’s essential that you have a JavaScript website that’s SEO optimized for mobile devices.

Build responsive web design into your JavaScript website so that your images fit on any screen size. That way, your website visitors will stay engaged for longer.
HTTPS Configuration
HTTPS protocol is the new gold standard for your website's security. 90% of all the web traffic that takes place on the Internet takes place on HTTPS-encrypted websites. It’s a signal that your users’ online behavior can’t be tracked, and their private information can’t be stolen.
Google labels HTTP websites as insecure and warns visitors against visiting the page. Websites that lack HTTPS configuration signal to their users that the website is illegitimate and dangerous. Your users can assume your website will make them vulnerable to cyber attacks or compromise their personal information.

Make sure that your website has an SSL certificate and renew it periodically, giving all of your URLs HTTPS protocols. Your users will feel assured that they can browse your website securely.
Page Speed
Page speed is one of the SEO ranking factors used by Google. Getting your web pages to load faster is one of the most effective ways to optimize your JavaScript website.

Most website visitors will bounce from a web page that takes longer than 3 seconds to load. That means users won’t visit your website and buy your products. It also negatively affects your SEO and your site’s search rankings because of Google algorithms that look at user metrics.

Use Prerender® to load your cached pages at blazingly fast speeds in under 5 milliseconds. Make your users and Google SEO crawling bots happy.
An XML sitemap helps Google understand your website’s structure - what URLs are on it and how they relate to each other. Creating a sitemap and submitting it to Google increases your visibility on search engines.

With HTML websites this is a simple, three-step process that takes just minutes. JavaScript pages, however, often have dynamically-created web pages that can result in thousands or tens of thousands of URLs.

It’s just not realistic to create a fresh sitemap every time you build your JavaScript website or app. You’re a busy web developer with a thousand other things to do.

Create an XML sitemap and submit it to Google Search Console, and repeat the process whenever you add a page to your JavaScript website. That way, you’ll ensure all your URLs are crawled seamlessly.
