JavaScript SEO-Friendly Checklist

Meta Tags
Your title tags and meta descriptions are the first things visitors see about your website when they’re searching on Google, so what they say matters. They should tell users as much as possible about who you are, what do you, and how you can help them.

Good SEO means 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 site.
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, which means your mobile version will be the one it ranks.

A web experience optimized for smartphones and JavaScript is essential for both users and search engines.

Build responsive web design into your JavaScript website so that your images fit on any screen size. This will keep smartphone users engaged longer.
HTTPS Configuration
HTTPS protocol is the new gold standard for your website's security. 90% of all web traffic 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. HTTP sites signal to users that they are illegitimate and dangerous, opening them up to cyberattacks or identity theft.

Make sure your website has an SSL certificate and renew it periodically so all your URLs have HTTPS protocols. Your users will always know their browsing is secure.
Page Speed
Page speed is one of the SEO ranking factors used by Google. Fast-loading pages is a great way to optimize your JS site.

Most visitors will bounce from a web page that takes longer than 3 seconds to load. That means less of them will buy your products, and your SEO and rankings will go down. After all, Google ranks based on their user metrics algorithms.

Use Prerender® to load your cached pages at blazingly fast speeds (under 500 milliseconds). Keep your users and bots happy.
An XML sitemap helps Google understand your website’s structure - what URLs it has and how they relate to each other. Creating a sitemap and submitting it to Google increases your visibility.

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 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.
