Does Google and Other Search Engine crawl meta tags if we call it using react .js ?

[RobinJA]

We have a site which is having only one url and all other pages are its components. not different pages. Whichever pages we click it will open show that with react .js . Meta title and meta description also will change accordingly. Will it be good or bad for SEO for using this "react .js" ?

Hi Robin,

There's no indication Google is having any trouble picking up the separate URLs and their associated Titles and Descriptions properly - a site: search for your domain returns all pages I'm able to find manually, and each page has a unique and accurate Title and Description snippet.

ReactJS is one of the most commonly used JS platforms, with a lot of momentum in the development community especially on high-traffic sites, and Google has innovated their crawl tech to include JS-support (they crawl with a headless version of Google Chrome) to adapt to this platform.

"View Source" is no longer valid for interpreting page code as Google will render it - they crawl with JS support, so JS interactions and modifications of source code are visible to Google. Using "Inspect Element" in Chrome shows a more accurate representation of what Google can crawl/render.

In short: I see no negatives for SEO here, and I expect at this point your analytics and Search Console data will show that your pages are indexed and eligible for traffic (potentially already getting traffic) from Google.

Best,
Mike

Have a look at the page view source of every page urls. Website url: http://www.mantistechnologies.com/

All the pages will show the same meta title and description. But it will dynamically call and display the right thing. While checking it with Moz browser plugin and Open Stats browser plugin. It is showing everything correct. So is that means my site is perfect or wrong? Does it harm my site in terms of seo or not?

Need an advanced opinion about my site from Moz team. Please have a deep look on my site URL mentioned above.
