As the weeks and months go by, more and more will flood the web. These are all URLs that will be misattributed to Google Shopping.
3. Google itself tells us not to use session-specific IDs nor ‘irrelevant parameters in the URL, such as referral parameters’
This is SEO 101. Google Merchant Center injecting this URL into every organic result has the effect of, in Google’s own words:
“…creating unnecessarily high numbers of URLs that point to identical or similar content on your site.”
Mueller says this query parameter “doesn’t affect crawling, indexation or ranking,” which may be true on a surface level. But anyone who’s been in SEO for a while knows that:
Crawling is affected when Google sees thousands of the same URL with unique query parameters and has to figure out what to do with them.
While indexing is technically unaffected (Google is just indexing the canonical URL and dynamically generating the srsltid= parameter on the fly), the practical effect is that Googlebot will potentially have to process hundreds or thousands of duplicate URLs.
As for ranking, many of us have anecdotally seen that canonicals, like 301s, do not necessarily pass full PageRank vs. a permanent, direct link. I would love to trust Mueller here, but past history isn’t comforting.
Get the newsletter search marketers rely on.
4. This change defeats the purpose of the rel=canonical tag
Ironically, the point of the rel=canonical tag in the first place was to avoid a situation where Google indexes and serves up multiple URL variations.
Regardless of how Google indexes these URLs, the practice of Google serving variations of the URL on the fly in organic search effectively defeats the whole purpose of the rel=canonical tag.
5. You can turn auto-tagging off – or can you?
Mueller does raise the option of turning off auto-tagging in Google Merchant Center but quickly hedges by saying, “Though it seems useful to me!”
His statement seems to brush off any suggestion that this is a problem and to tell everyone to accept this as the new normal.
Either that or he knows this is a problem but has to maintain a unified face to the world.
From my perspective, these are all pretty weighty implications, not just because they affect SEO hygiene but perhaps more importantly because the way they’re designed can result in a lot of misattribution to Google Shopping.
The problem with Mueller’s advice that you can turn this feature off is that it contradicts Google’s own documentation, saying that auto-tagging is a required feature.
To make matters worse, the only link Google provides for manual tagging includes disclaimers stating it does not apply to GA4.
Any SEO who wants to tell their team to shut off auto-tagging is in an awkward situation: They have to tell their team to shut off a feature that Google says “is useful” without providing a viable alternative.
6. This breaks the long-time Google ‘rule’ that organic listings are sacrosanct
This part is the most surprising of all. When I spoke with some Google engineers in the early 2000s, they took some pride in telling me that their organic search team was walled off from the rest of Google – literally.
This was a large factor in their early success; while their competitors at the time routinely compromised their user experience to increase profits, Google organic was always independent from AdWords and other parts of Google.
This is the first time I’ve seen another Google department mess with the organic results and it’s not a good sign.
Analysis
So, how should Google fix this? Simple.
Return to applying auto-tagging only to results in the Google Shopping tab and product listings in universal search. Leave the organic listings alone.
Google already does this with the gclid= parameter on paid search results. There’s no reason it couldn’t do the same with product listings.
Look, I get it. The Google Shopping team wants to enhance its analytics to report on how a product performs across Google’s paid, shopping and organic listings.
But hijacking Google’s crown jewel – organic search – is not cool. The Shopping team should treat links on Google organic just like they would from Bing, Facebook, X or ChatGPT.
Google used to be more transparent about these things. In this case, it would be nice if there was a little more communication about their plans to address it before a billion unwanted srsltid= parameters litter the web.
What to do next?
If you’re a site manager and you see the srsltid= parameter starting to appear in your inbound links, my suggestion would be to turn it off.
Go to Google Merchant Center and shut off auto-tagging.
Use Google’s Campaign URL Builder for GA4 to manually create tags for each product and submit those in your feed to Google Shopping.
Keep your fingers crossed that with all the attention that this issue continues to generate, Google will finally get the hint and fix it.
