To solve the issue, follow these steps:
1) Perform Pre-rendering or Server-side rendering
Performing one of the above rendering techniques helps you to create individual HTML files for each route on the router file. If you have less than 15 routes on the router file then you should prefer pre-rendering technique. Make sure that the website does not have dynamic URLs or content on the website. The best part is that the pre-rendering technique does not require a back-end framework like node.js or express.js.
2) Use Sitemap.xml node.js package
3) Meta package to add meta tags
As discussed above, there is just one HTML file and every time this HTML file gets loaded. In this situation, it is not possible to load unique meta tags for each route. To resolve this issue, you need to install an additional package called meta-tags. With the help of this package, you can add meta titles, descriptions, keywords, and canonical tags on each route in the router.js file.
4) Use lazy-loading
Along with lazy load, you can use the hexadecimal numbers to load the data in the least amount of time. All you need to do is convert hexadecimal to decimal numbers and save it to the database. The hexadecimal conversion helps you to show all the incoming data from the database faster and hexadecimal to decimal helps it occupy the least amount of memory in the device.
