Adwords and Analytics Conversions: Huge drop after moving to https

Visitor ✭ ✭ ✭

Hi there.

 

A few weeks ago, we migrated our e-commerce website to Magento. And at the same time to full HTTPS.

 

I track conversions by linked AdWords and Google Analytics (GA is tracking conversions OK it seems)

 

Overview of changes:

 

  • Whole new site with new design
  • New HTTPS urls (redirected old ones with 301)
  • Magento

I used AdWords editor to:

  • Duplicate and pause existing campaigns.
  • Change all old ad urls to correct HTTPS urls.
  • Publish new campaigns and updates to Adwords.

So after uploading the changes, i expected a little turbulence in AdWords and that it would settle within a few days.

 

But that does not seem to be the case.

 

The thing is that I've only got 1 conversion attributed to AdWords for a few weeks now.

Before that, roughly the same period, we'd gotten 35 conversions attributed to AdWords.

 

The graph has flatlined completely if not for this one conversion.

 

In AdWords, the clicks, CTR, Pos. etc are about normal so we should be getting some conversions registered.

 

I'm wondering if i've forgotten to do something in AdWords or Analytics.

 

Do you have an idea about what could be the problem?

 

Regards, Victor

Hi Victor,
In AdWords, are you using imported GA transactions as conversions or are you using the standard AdWords conversion tracking code.

Are you sure that the AdWords conversion tracking code is firing on the receipt page? Can you check using the "Tag Assistant" chrome extension if the tag is installed correctly and if it's conflicting with any other tags?

Hi Dave and thanks for the reply.

I'm using imported GA transactions as conversions.

I've used, Tag assistant, the old GA Debug extension and Chromes network tab to see what gets sent.

The Tag assistant says: "Adwords auto-tagging detected" and a string that matches the gclid that the page is requested with. It's registered as a pageview.

I'm wondering if the payment gateway is somehow responsible. Here's the url and query for one transaction item:

url: https://www.google-analytics.com/collect
query variables:
dl - https://www.tapetforum.dk/checkout/onepage/success/
dr - https://ssl.ditonlinebetalingssystem.dk/integration/ewindow/Default.aspx?close=1&sessionid=10558614&...
_utmz - 136747061.1434978027.2.2.utmcsr=google|utmccn=(organic)|utmcmd=organic|utmctr=(not%20provided)

Then a whole load of other query variables of course. But that _utmz looks like it sets the transaction to organic, (not provided) etc.

Maybe that's overriding the first pageview with the AdWords gclid?

I'll try writing to our specialized Magento hosting provider and google some more. If i find a solution, i'll post it here.

But i still welcome any answers, insights and comments on this issue until it's resolved.

Regards, Victor

Hi Victor,
That's it. The payment processor is completely overwriting the utmz. Can you confirm that they're different?

I think you may be able to stop this without actually contacting the payment processor. If you add the domain(s) of your processor and their online banking .dk domain to the referral exclusion list in your GA settings, GA will ignore this and should hopefully start registering the transaction correctly.

Hi Dave.

Actually I can't. It kept showin the same _utmz string.

But I'm using Universal analytics and that shouldn't use or add a _utmz cookie.

I got pretty confused but i've cleared my cookies and now I don't get _utmz.

I've added the payment gateway to the referral exclusions list and i hope that does the trick.

I'll update this thread when I know more or have the solution.

Thanks for the help Dave.

Regards, Victor

Well, it looks like what did the trick was adding the payment gateway domain to the referral exclusion list.

 

(Remember: this is an ecommerce site using analytics for conversion data)

 

What happened to us was that we made alot of changes at the same time:

  • Move from HTTP to HTTPS
  • New category and product urls
  • New AdWords ads with updated urls
  • Moved to Universal Analytics

 

Things I would recommend people to do:

 

Verify that tracking is working by:

 

Clearing your cookies

The old cookies had me confused while I was using Universal analytics on the new site. This spares you from googling some cookie that is not actually in use.

 

Get Google Tag Assistant for Chrome

I did have this tool for chrome besides an older console based version. It's great to see what is happening.

 

Test the process through to the receipt

See the data that is sent to Analytics in Tag Assistant.

Remember to have a Analytics filter so you don't add to conversion data in your analytics

 

If tracking is OK then:

 

Diagnose if you have a referral traffic problem

If theres missing conversion data in AdWords, take a look at your analytics referral traffic.

Acquisition > All Traffic > Referrals

Sort by transactions and there you'll likely see your payment gateway url/domain as the top referring domain with transactions.

This means you should add this domain to the referral exclusion list.

 

Solution:

 

Adding to the referral exclusion list

Under administration (Or Admin if you're already in a reporting view) > Property (center column) > Tracking info > Referral Exclusion List

 

This seems to have done the trick for us and I thank Dave_Davis for his help. And I hope this helps others as well.

 

Have a great day.

 

Regards, Victor

HI Dave
May I ask you a question.
We see our gclid tracking all through out our site. But when the customer gets to the magento cart page the gclid vanishes. Therefore all my conversion data in GA looks like direct traffic. Is there anyway to solve this problem?

Thank you.
