Server-Side Rendering: Rendering content on the server before it is sent to the user’s browser can make it easier for search engines to crawl and index the content.
Lazy Loading: Delaying the loading of non-critical content until the user scrolls down can improve page speed and user experience, while also making it easier for search engines to crawl and index the content.
Dynamic Rendering: Using dynamic rendering techniques to create static HTML versions of dynamic pages can make it easier for search engines to crawl and index the content.
Use of Sitemaps: Including a sitemap that lists all the URLs on your website can help search engines discover and index all your content.
Optimizing Metadata: Ensuring that your website’s metadata, such as title tags and meta descriptions, are properly set and optimized for search engines.
Google processes JS in three phases:
Image Source: Google
Googlebot crawls the page: Googlebot, Google’s web crawling bot, starts by requesting the page’s HTML from the website’s server, just like it would for a traditional website.
Content is indexed: Once the page is rendered, Googlebot will index the page’s content as it would for a traditional website.
Server-Side Rendering vs. Client-Side Rendering vs. Dynamic Rendering
Server-side rendering, client-side rendering, and dynamic rendering are all techniques used to render content on a web page. Here’s a brief overview of each technique:
Dynamic rendering: Dynamic rendering involves serving up different versions of a web page depending on whether the user is a human visitor or a search engine crawler. For human visitors, the page can be rendered using client-side techniques, while search engines are served a pre-rendered version of the page using server-side rendering. This can improve page load times for human visitors while still ensuring that search engines can crawl and index the content.
Each rendering technique has its own advantages and disadvantages, and the choice of technique will depend on the specific needs and goals of a website. Server-side rendering is generally recommended for websites that need to maximize SEO and performance, while client-side rendering is better for websites that require a more dynamic and interactive user experience. Dynamic rendering can be a good compromise between the two, providing the best of both worlds.
Use Google Search Console to Find Errors
Googlebot is based on Chrome’s latest version. But it doesn’t behave the same way as a browser.
Which means launching your site doesn’t guarantee Google can render its content.
The URL Inspection Tool in Google Search Console (GSC) can check whether Google can render your pages.
Enter the URL of the page you want to test at the very top. And hit enter.
After a minute or two, the tool will show a “Live Test” tab. Now, click “View Tested Page,” and you’ll see the page’s code and a screenshot.
Check for any discrepancies or missing content by clicking on the “More Info” tab.
A common reason Google can’t render JS pages is because your site’s robots.txt file blocks the rendering. Often accidentally.
Add the following code to the robot.txt file to ensure no crucial resources are blocked from being crawled:
