lander click urls -- --> not backing out to offer page?
Hi STMerz,
Currently I've set up a campaign in Voluum with 6 landers (cleaned and ripped from spy tools).
When I copy campaign URL from Voluum and paste into Chrome (desktop)....
It correctly directs me through the funnel of all 6 landers, and each lander click URL correctly directs me to the offer page.
However..
When I use the same campaign URL on my iPhone (safari / chrome):
3 of the landers direct to the correct offer page.
Remaining 3 direct to a page that say 400 Bad Request - nginx.

It's always the same 3 landers and the issue only happens on mobile. On desktop, they direct to correct offers.
In hindsight, I never checked my previously launched campaign urls on my mobile...**queue the sound of a small violin in the background 
** so this could have been draining conversions from my camps !!
Seriously though, I spent like 2 hours trying to figure this out lol. Any suggestions?
- All urls in my camp have https
- I'm using campaign url from voluum (not the lander url)

Have you tried opening the lander urls on the phone directly?
If the lander works on the phone without the campaign than the lander is not the problem.
Next thing to check is the offer. Some offers are only for certain carriers, phones and regions (i.g. wifi only,Vodafone only, Android only etc.). So could be that the offer is not supported for your phone and or carrier.
Check with your network if a wrong targeted offer is directed to a smart link. Sometimes you need to enable that option. Ask your AM.
Last but not least: Which domain is giving you the 404? Is it the url from the affiliate network, from your lander or some other random sh*t?

Hey Lars - I've troubled shooted with your suggestions, please see below:
Have you tried opening the lander urls on the phone directly?
Just tried doing that, and still get the same error when visiting the offer page.
Next thing to check is the offer.
To troubleshoot this one, I swapped out the offer url with the wikipedia homepage. The same 3/6 landers are still rendering the 400 Bad Request error </3 ;(
Which domain is giving you the 404?
Whatever domain I direct people to from my lander using the click url. Doesn't matter whether it's wikipedia or the offer URL, I still get the 400 error.

Found the issue!
The landers that were not directing traffic to the offer pages correctly had this line of code in the CTA button:
and / or this line in the header:
Code:
<meta name="referrer" content="never">
I'm a code noob so I googled what it meant and he's what I found:
"
In short, the noreferrer tag hides referrer information when the link is clicked."

I'm fairly certain that this interferes with your tracker. As soon as a no-referrer is used, the tracker loses the information it needs to direct you to the offer page (no idea why, I'm not technically-inclined :P )
Time to re-test the offers I incorrectly excluded b/c of this...

I had to read this a read this a few times. You're mixing and matching the words campaign, offers, and landers pretty loosely, but I think I got it.
Two different things happening here.
One: Your landers are broken.
3 of your landers don't work on mobile. Get rid of those landers or fix them. 6 is too many to split-test anyway.
Two: The offer (when they click your CTA from your landers that do work) is un-targeted:
You are trying to visit the offer from a non-targeted device/geo/user-agent/etc. You can't fake that with vpn/ua-switcher. Some network redirects (basically a smartlink for non-targeted traffic) only happen on desktop/mobile, which is what you are seeing on the desktop.
As lars said, visit the offer url directly. Check if the visit shows up on the network dashboard for the offer.
If it does, it's fine. If it shows a new impression but says something different like 'global redirect' you're still fine.
Get rid of the 3 broken landers and make sure the offer link registers a visit on your network dashboard and you're good.

Jaybot - Yeah, judging by the responses I think I've jumbled some terms up which may have been confusing - my bad
However, I was able to fix up the broken landers. Also removed one completely so there's less landers to test overall.
Lastly, I was able to see visits on the network dashboard for the offer when checking.
So, looks like I'm ready to launch

Just a thought, are you still opening the full campaign url even on mobile (exactly as displayed in Voluum), most of these problems happen when people test the lander urls directly, or they leave out some part of the url as they don't want to retype it all... this way the tracker doesn't "know" where to send the click and the bad request error pops up.

Hey Matuloo,
Yep, I was copying the campaign URL exactly as it was from Voluum, then on my iPhone inputting that URL into an incognito browser.

But everything works fine now, which is great

So what was the problem in the end? Some error in the code of the LP or was it related to the offers?

@matuloo The issue was caused by two strings of code being in the lander:
Code:
<head>
<meta name="referrer" content="never">
</head>
and
Both of these pieces of code hide referrer information when a CTA button link is clicked.
When I removed these pieces of code, all landers correctly forwarded me through to the final offer.
It's important to note the 400 error was only happening on iOS, not desktop.
Please excuse my crappy paint drawings, but just so we're on the same page here is what was happening:
I contacted
Voluum support and they responded this morning, here's an interesting snippet of their response:
The difference between iOS and desktop is that iOS blocks the 3rd party cookies, so in this case, Click URLs rely only on the "cep" parameter that passes the encoded visitor information and which is being appended to the lander URL after the redirection. In case of any additional redirections or implementing the Click URL in some non-standard way, it may not work properly.
My guess is that if you have a lander with 'no-referrer' code AND your visitors are using an iOS device...your tracker has no way of passing on info / screws with the tracker so your visitors will always get the 400 error, so you'll never get iOS conversions on those landers

Thanks for the update... time to check the code of some of my landers I guess

If you use Sublime you can edit whole LP directories with sub-directories in bulk.
Checking and changing hundreds of landers takes a few seconds that way.

I think I'm safe, didn't really notice any such problems and the conversions would be low in this case so I would notice anyways... but I will check a few random one anyways, just to make sure
