304 "If Modified Header" Triggers Error in Google Ads?
-
We have a client who is launch some Google Ads campaigns, and they recently asked us to fix 304 "Errors" on their website as per this feedback:
"When we inspected the website we came across a number of 304 status errors. In order to get the ads running, we will need all of the website domain status codes converted to 200. “
Of course, all of their website pages return a 200 Status, it's just the HTTP headers that additionally clarify with a 304 Response (not an error).
Has anyone else ever run into this issue with Google Ads? IMHO it makes no sense to remove this functionality. Google has even recommended in the past to use this it:
https://webmasters.googleblog.com/2008/11/date-with-googlebot-part-ii-http-status.html
Thanks for any tips or feedback!

So - we pushed back a bit because we seriously couldn't fathom why we'd need to remove all of the 304 functionality from the website due to a directive from the Google Ads team.

Turns out, our gut instinct was right. The client's PPC agency ended up giving the Google Ads team a call, and then they learned that there was actually a 404 error happening (face palm) for one page. Not a 304.
Leaving this post here for good measure in case this ever happens to anyone else. Watch out for typos!

This means that Google believe there is an error with the landing pages which you have entered for your ads. 9 times out of 10, this comes down to someone putting the wrong URL into the Google Ads back-end and then having issues. This is especially the case for 3XX errors which usually indicate that redirects are at play. In your case, the story seems to be a bit different
Google is telling you that when they visit your landing URLs for your ads, instead of the ad connecting straight to the page, Google gets redirected:
"The HTTP
**304 Not Modified**client redirection response code indicates that there is no need to retransmit the requested resources. It is an implicit redirection to a cached resource."So basically, Google cannot load your landing page because they are being redirected to a cache of the landing page instead of the live URL. This is unlikely to be down to someone entering the URL incorrectly in Google Ads (as that would be more likely to spawn a 301, 302 or 307). If you keep serving Google a cached version of your landing page, they can't know what's underneath of that redirect. As such, they can't trust the contents of the web-page
Some unscrupulous marketers, might use a 304 to get Google to evaluate a fake landing page, then send actual users to a completely different landing page (other than the one which Google evaluated). My guess is, this is a vulnerability which Google are unwilling to tolerate on their ads platform

• googie-anaiytics[.]com
• vty68[.]net We have asked our Website vendor to scan and they found nothing. We would be greatly appreciated if you could help. I tried Google Search Console and even the tool Google Safe Browsing that Google itself suggested but both the tools showed that our website does not have any malicious links at all. And yet Google Ads support team keeps telling us our page contains these links. I am wondering if anyone in the community has experienced this before and how did you address this issue. Or could you guys please help to share any tools that you know can do a deep scan on this page and if possible our entire website to help us identify where the links are located? Please let me know if you need any additional information from us and I would be happy to provide it.3 -
Can Google Shopping Ads Lower Ranking due to Bounce?
I am noticing Google Shopping Ads are showing up for really irrelevant keywords on some of my products. This quite predictably causes a high bounce rate when a user comes from these ads. There is very little control over what Google Ads seems to decide are relevant keywords from what I can see. Only control is by viewing search terms and setting as negative keywords, but his doesn't help much. Negative keywords are often ignored or they come up with some other really irrelevant new keyword. Seems this high bounce rate could hurt ranking? Any experiences shared with Google Shopping ads appreciated!

Does having redirects in a Adwords text ad destination URL hurt quality scores?
I recently noticed that one of my clients had several redirects in their Adwords text ad destination URLs. I updated the destination URLS to land on the final location (thereby losing all the text ad history). However I'm wondering if this could have any impact on the text ad quality scores (none of them were disapproved).

Google URL Builder / Campaign Tracking on two Different Domain using the Same Analytics Code
Hey Everyone, I think I know the answer to this but I'd like to get some confirmation. I currently have a landing page at "www.xyz.com", it's a separate domain in which only the landing page exists and not a vanity URL which redirects. However, the navigation and all the links on "www.xyz.com" actually link out to "www.abc.com". The domain / landing page "xyz" has the same analytics tracking code as domain "www.abc.com". My question is this, if I use Google URL builder to create custom URL's to track for each ad that I'm running in Adwords, will this data show up in the analytics of "abc" even though it's a separate domain because it has the same analytics code? In other words, does campaign data show only if the domain and the google analytics code line up, or does the domain not matter and as long as you have the same analytics code (despite two separate domains) that campaign data (built through Google URL builder) will show? My hunch and best guess it that as long as the analytics code is the same (regardless of a separate domain) that the data in campaign will show with the custom URL's I build. I'm aware that I can test this and I will but I'd like to get an idea from the community first to make things easier. Anybody have experience with this? Answers greatly appreciated! Thanks!

Increasing Google Ad spend - is it worth it
Hi We are currently spending approx £500 pcm on google ad words however if I increased this spend to £4000 pcm what kind of results would this achieve? For example would it just be more visits per day as the budget is larger? Also what is the best way to track the success of an adwords campaign - the ultimate goal of the campaign would be to generate a lead whether this be a phone call, email or using our book an appointment form. Our service covers a geographical area (Scotland) and for organic search we are doing well 1st pages listings for searches such as pvc doors edinburgh etc so I am unsure whether it's worth increasing my PPC spend or put more resource into SEO, or even Facebook ads?

Adwords: Brand ads appear bottom of SERPs
Hello, I'm running a sale promotion on a brand only Adwords campaign (I have the only account with trademark authorization) and have noticed that my ads are appearing at the bottom of the first page on Google. This happened last week so I split the campaign into three Adgroups and that fixed the problem but today I'm running brand only and there is no way to separate them. CPC has also increased dramatically. Normally it's less than 10 cents and now it's sitting at between $2-$4. Has anyone else seen this? Any ideas/advice on how to stop this happening? It's playing havoc with my CTR and conversions. Much thanks,
