search engine optimisation Optimized Affiliate Hyperlink Redirect with Cloudflare Employees

I didn’t need my staff to examine each URL however simply affiliate hyperlink redirects. So, I exploit the trail /goto/ for all my affiliate hyperlinks.

I like to recommend that you just arrange a identifier to your affiliate hyperlinks. Probably the most commons are goto, go, recommends, and out.

Then, I didn’t use the Response.redirect perform. I couldn’t discover a approach so as to add the X-Robots-Tag HTTP Header to stop serps to index my affiliate hyperlinks by utilizing it.

So, right here’s the code with the fixes to all these issues.

The Code I Use to cloak affiliate hyperlinks with CloudFlare Employees

That is the code I added to CloudFlare Employees with my 300+ affiliate hyperlinks within the redirectMap.

const redirectMap = new Map([
  ["/goto/2checkout/", "https://www.2checkout.com/referral?r=e230f815a7"],
  ["/goto/3dcart/", "https://shareasale.com/r.cfm?b=770466&u=941349&m=3609&urllink=&afftrack=0"],
])
async perform handleRequest(request) {
  const requestURL = new URL(request.url)
  const path = requestURL.pathname;
  const location = redirectMap.get(path)
  if (location) {
    let response = new Response(null, {
      standing: 302,
      statusText: "Discovered"
    })
    response.headers.set("X-Robots-Tag", "noindex,nofollow")
    response.headers.set("Strict-Transport-Safety", "max-age=63072000; includeSubDomains; preload")
    response.headers.set("Cache-Management", "max-age=604800")
    response.headers.set("X-Redirect-By", "cloudflare")
    response.headers.set("Response", "302")
    response.headers.set("location", location)
    return response
    }
  // If request not in map, return the unique request
  return fetch(request)
}
addEventListener("fetch", async occasion => {
  occasion.respondWith(handleRequest(occasion.request))
})

The a part of the code that you just’ll modify is the Map of affiliate hyperlinks.

const redirectMap = new Map([
  ["/goto/2checkout/", "https://www.2checkout.com/referral?r=e230f815a7"],
  ["/goto/3dcart/", "https://shareasale.com/r.cfm?b=770466&u=941349&m=3609&urllink=&afftrack=0"],
])

On every line, you add the quick URL and the actual affiliate hyperlink you need the consumer to be redirected to. Take note of the comma after every line.

I’ve 300+ affiliate hyperlinks and the typical backend processing by CloudFlare is 1ms. It’s blazing quick.

How the Affiliate Redirection Code Works

When the employee script is executed, the handleRequest perform known as with the request, the affiliate hyperlink to redirect. Ultimately, we route the employee to be executed just for affiliate URLs.

The handleRequest perform will first take away the area from the URL to maintain solely the pathname for comparability. Then it tries so as to add the vacation spot for that pathname right into a variable if it’s within the Map.

const requestURL = new URL(request.url)
  const path = requestURL.pathname;
  const location = redirectMap.get(path)

Then, it checks if the trail identify is within the checklist of affiliate hyperlinks. If it finds it, it creates a brand new HTTP Response to be despatched with a 302 standing.

if (location) {
    let response = new Response(null, {
      standing: 302,
      statusText: "Discovered"
    })

It provides the X-Robots-Tag HTTP header and set the worth to noindex, nofollow. This manner, serps gained’t index your affiliate hyperlinks.

response.headers.set("X-Robots-Tag", "noindex,nofollow")

It provides one other HTTP header, the HSTS HTTP header, to pressure https encryption and at all times use https.

This line of code can break your web site should you don’t use HSTS. Nevertheless, it’s extremely beneficial so as to add this safety HTTP header so as to add one other layer of safety to your web site. In any other case, take away this line.

response.headers.set("Strict-Transport-Safety", "max-age=63072000; includeSubDomains; preload")

It provides cache management and a approach to examine that your hyperlink was redirected by CloudFlare.

response.headers.set("Cache-Management", "max-age=604800")
response.headers.set("X-Redirect-By", "cloudflare")

Then, it provides the HTTP Response code: 302.

Lastly, it provides the actual HTTP header for redirection: location and return the brand new HTTP Response.

response.headers.set("Response", "302")
response.headers.set("location", location)
return response

The redirection HTTP header obtain the vacation spot URL as an argument. So, as soon as the browser receives that response, it’s going to respect the situation header and redirect to the affiliate provide.

In any other case, if the affiliate hyperlink doesn’t exist, it forwards the request to be deal with by your browser or server. (404 error web page or one thing else)
