The _adin parameter shouldn’t affect SEO. Google algorithms are smart enough to detect if a parameter must be indexed or not. In very few cases, Google has indexed URLs with our _adin parameter.
We’ve spoken with 10 of the best SEO experts who have audited our _adin parameter. They all concluded the same thing:
_adin parameter DON’T affect SEO rankings.
To avoid all potential SEO problems, they recommend adding Canonical in all your URLs.
Here’s a step by step guide on how to do that:
1. Add the self-referencing canonical tag in all your pages.
<link rel=“canonical” href=“https://yourdomain.com/page-canonical/” />
Doing the self-referencing 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, (even if you are not using the SEAL PRO Package).
If you implement the canonical tags correctly, the _adin parameter will not affect your SEO rankings.
SEAL tells Google to ignore the _adin parameter.
2. Inform Google via Google Search Console:



and Save 🙂
Delayed _adin parameter by default
You don’t have to do anything here. The _adin parameter is loaded a couple of microseconds after the page is loaded. SEAL does this by default.
If you are currently subscribed to the PRO plan and still don’t feel comfortable working with _adin parameters, you can easily downgrade to the Basic Plan (79€/mo) and track all your traffic and conversions without _adin; but you won’t be able to track your conversions by source/campaign/terms.
