How Adin Parameter Works

How can we track conversions by source if we don’t track individual customer journeys?

We have created a Source-ID System (SIS). This system creates an ID for every referral to your site. For example:

If a user accesses your website from SEO and the landing page is your Home Page, the SIS creates a source-id with the number 1.

You’ll see this source-id added in your URL with the parameter yourwebsite.com/?_adin=1

So, every time a user visits your website from SEO and lands on your Home Page, Seal Metrics tracker code will add ?_adin=1.

Seal Metrics is going to use this source-id (adin) to assign it, when the conversion is done to the correct adin.

How does Seal Metrics know the correct adin per each conversion?

Once Seal Metrics adds the adin for each visitor, every time your visitor makes a page view, Seal Metrics will keep the adin in every page view up to the end of the journey.

For example:

  1. Access to sealmetrics.com from this link.
  2. Visit the Pricing page
  3. Visit the Why page

You’ll see how adin parameter is at the end of the url.

Once you convert in Seal Metrics, our conversion pixel, we’ll check which is the adin that makes the conversion

_Adin Architecture explained:

There are some important points to explain how _adin works:

  1. _adin code is a unique id code for each mix of source – medium – campaign – term – landing page.
  2. _adin code is generated automatically each time Seal Metrics detects a new referrer/utms.
  3. _adin code never tracks or will track user id. We don’t track Users!!

Important _adin Recommendations:

Usually, the _adin parameter shouldn’t affect SEO. But Google could index some of your URLs with our _adin parameter. You can follow these SEO recommendations.

Usually, this shouldn’t happen!!! Google algos are smart enough to detect whether a parameter must be indexed. But we can avoid SEO problems by following these easy recommendations:

Add Canonical in all your URLs.

We’ve talked with the best SEOs, we’ve audited our _adin parameter with them and these are the conclusions.

_adin parameter DON’T affect your SEO rankings.





We recommend following these recommendations:

1. Add the canonical tag in all your pages.

<link rel=“canonical” href=“https://yourdomain.com/page-canonical/” />

Doing the canonical you’ll inform Google that the correct page is “https://yourdomain.com/page-canonical/”

We strongly recommend adding the canonical tag in all your pages for SEO reasons, though you’re not working with SEAL PRO Package.

If you’re working your SEO correctly with canonical tags, _adin parameter will not affect your SEO ranking at all.

We even go further and let Google know that parameter _adin should be ignored.

2. Delayed _adin parameter

Even though we’ve gone a couple of steps forward, and _adin parameter is loaded a couple of microseconds after the page is loaded.

3. Google SEARCH Console:

Google knows and identifies SEALMetrics’ adin parameter and won’t index the URLs with adin parameter, as you can see in the image below:
