Redirect Domain To LinkedIn Profile Page

One additional option is to use a CloudFront function to do the redirect. It is pretty straightforward. Here is an example of how to accomplish this using a CloudFront function.

https://docs.amazonaws.cn/en_us/AmazonCloudFront/latest/DeveloperGuide/functions-tutorial.html

In the example above, replace the location response header (line 9) with the URL to your LinkedIn profile.

I should add, this option does not require any Route53 magic. Just create your Route53 CNAME record to point your personal domain to the CloudFront domain name, and then follow the steps in the tutorial I linked above.

The methods you mentioned are all using CNAME. It is used when you own both domain names. But I guess you are not the owner of linkedin.com. So they won't work for you.

Instead, you can use client script redirect or HTTP redirect.

Client script redirect:

You can host your website on S3 (https://docs.aws.amazon.com/AmazonS3/latest/userguide/WebsiteHosting.html)

Configure route53 to route your domain name to the S3 bucket (https://docs.aws.amazon.com/AmazonS3/latest/userguide/website-hosting-custom-domain-walkthrough.html)

And then in your website, use javascript to redirect user to the URL you want (https://www.w3schools.com/howto/howto_js_redirect_webpage.asp)

This is the cheapest way.

If you don't want to use javascript, using HTTP redirect also works, you can use ALB to achieve that (https://aws.amazon.com/premiumsupport/knowledge-center/route-53-redirect-to-another-domain/#Redirecting_domain_names_or_redirecting_from_HTTP_to_HTTPS_using_an_Application_Load_Balancer)
