Search engine optimization(SEO):

1: Provide Title, description and Meta information.

2: Sitemap: it is a file. It will keep all possible pages(links) of your app that we wanted to get indexed (improve the SEO).

3: robots.txt: it says,

• What are the pages you should crawl?
• What are the important pages that I have?
• What are the pages you should not index, for example admin page?

4: canonical tags: canonical means identical. It says, This is the temporary page, the permanent page is some other page, and please don't index me, please go and index the permanent page that I have.

5: Use semantic HTML tags.

6: The better the page speed, the better the indexing. If your site is slow, then it will never be listed at the top. Note: Page speed affects SEO.

7: SSR is better.

8: SSG is better for both SEO and page speed because SSG is already generated and cached. If a request comes, then the SSG page is served quickly.

• anything that is related to the sales page or anything product that is highly searched, or any product detail page that is consumed, these kinds of pages you can prefer SSG and put it on CDN.

10: CSR is not good (use an alternative): on the server, generate static HTML for the crawler, but for all other users, I will make a CSR.

11: Shareable links :

• Search/ filter should be part of the URL, so the user can easily access it.
• Readable URL links: URL also plays an important role in SEO. Instead of putting random IDs, you put readable strings in the URL.
