Turbocharge SEO of your AngularJS apps through server-side rendering (SSR) with Angular Universal. SSR serves search engines with fully pre-rendered HTML, bypassing client-side JavaScript needs. Use SSR like so:

# No pain, no SSR gain!
npm install @nguniversal/express-engine --save
app.engine('html', ngExpressEngine({ bootstrap: ServerAppModule }));

With SSR, your app's searchability and indexation improve like magic, and become an absolute SEO booster.

AngularJS application's compatibility with search engines

Let's delve deeper into how you can fine-tune your application's compatibility with search engines. SEO is a vast subject and covering it all here would be impossible, but we can certainly underline the main points.

Implementing clean Angular URLs

Clean URLs are essential for any AngularJS application. Rather than using hash-prefix (#), implement HTML5 mode for cleaner URLs by enabling html5Mode in the $locationProvider.

// Because beauty matters, even in URLs!
$locationProvider.html5Mode(true);

Building clear sitemaps and status codes

Having a sitemap can be beneficial for search engines to map your site and index it accordingly. Include appropriate HTTP status codes to handle missing pages and permanent redirects correctly.

Pre-rendering dynamic content

For dynamic parts of your app managed by {{}}, make sure the content is pre-rendered. Doing so ensures the search engines can see your content, thereby boosting your SEO. You can utilize services like Prerender.io or Brombone to help automate this process.

Setting up SEO configurations

For better SEO outcome, configure your app with meta tags such as <meta name="fragment" content="!">. Also, structure your data markup to improve your listing. Validate these settings with tools like Google Schema Markup Testing Tool.

SEO tactics for Angular Applications

HTML5 PushState over hashbang URLs

Choose HTML5 PushState over hashbang (#!) URLs for a more effective approach. Note that Google doesn't prefer _escaped_fragment_ anymore, so it's best to use the history API.

Bing and alternative search engines

Never ignore other search engines, like Bing. Use tools like Bing Webmaster Tools to optimise your app for these search engines as well, covering all grounds for SEO success.

Utilising meta tags and rich snippets

Incorporate relevant meta tags and rich snippets using schema.org vocabulary. This enhances content presentation in search results, providing structured data to search engines.

Monitoring and analytics

Consider using analytics tools (like Google Webmaster Tools). These tools provide insights on your site's rendering and potential SEO issues, and they let you perform search analytics.
