merchantcenter : many produits blocked landing pages mobile&desk -Robots.txt

Shopify Discussion

Hello,

I’m facing an issue with Merchant Center where several of my product listings are blocked from being shown due to “mobile and desktop landing pages not available.” According to Google Ads support, the issue seems to be related to the robots.txt file.

After examining the landing pages for some of the rejected products, the Merchant Center support confirmed that the pages were accessible. However, they noticed an issue with crawling errors, specifically a “Page Not Found (404)” error, which might indicate a problem with the landing pages associated with these products.

this is the google instuction :

User-agent: Googlebot
Disallow:

User-agent: Googlebot-image
Disallow

→ my current robots.txt file :

we use Shopify as our ecommerce platform

Ajout d’instructions spécifiques pour Googlebot

User-agent: Googlebot
Disallow:

User-agent: Googlebot-image
Disallow:

{% for group in robots.default_groups %}
{{- group.user_agent -}}

{% for rule in group.rules %}
{{- rule -}}
{% endfor %}

{%- if group.sitemap != blank -%}
{{ group.sitemap }}
{%- endif -%}
{% endfor %}

I added the suggested instruction to my default shopify robots.txt, resubmitted the sitemap on Search Console, but the problem persists.

. Has anyone encountered this before or have a solution? Any help would be greatly appreciated!

Is the issue on some random products or all products?

If just random products, these usually auto resolve by itself, and the issue is just due to Poor DNS connection, random slow loading, etc.

But if its all your products, or the amount of products with the issues grow, then this needs to be looked at deeper.

Thank you for your feedback, the problem appeared about 2 weeks ago, many of my product variants are refused on merchant center and it increases every day (which is strange on the same product I have validated variants and others not): Google support informed me that there is a crawling problem: page not found (404) so ​​a problem on landing pages on mobile and desktop
asked me to check that my product landing pages do not redirect to a domain other than my root domain because I have a subdomain in www.domainname, that’s what I did and they asked me to integrate the googlebot instruction

User-agent: Googlebot
Disallow:

User-agent: Googlebot-image
Disallow

on my robots.txt file and that’s what I did too and requested a web verification but there is still the same problem! Thank you for your help if you have a solution.
