Can the end of a competition cause a drop in organic visitors?
-
Hi everyone,
Over the last six months I've been running a few competitions on my largest site, but noticed a very large decrease in organic sessions just after the third one ended.
For reference, the site is ~10 years old and gets a couple of million sessions per month.Organic sessions throughout last year and before the holiday periods were around 800k/month, which then increased by 50% during the holiday period alongside a competition I ran.These competitions double the pages per session and add another 1.5 minutes onto session duration.
At the end of one of the competitions this year, daily organic sessions halved overnight and are now below the baseline of last year - and not improving.
Some possible causes include;
- Google update - unlikely, because the date of the drop doesn't coincide with any increase in SERP volatility that I can find
- The extremely quick overnight drop in engagement (pages/session and session duration falling back to pre-comp baseline) caused Google to believe our site to be less popular and thus less deserving of rankings
- Visitors who've been bombarded with month-long competitions are sick of seeing them and are not searching for my site so often
- Email tagging - in the week before, UTM tracking parameters were added to all emails (of which there are a lot of subscribers) - as the number of Email visitors in Analytics increased, Organic did slightly decrease at the same time. I think this is unlikely, but I wonder if somehow some of our email visitors were previously being classed as Organic as well as some being Direct
- Incorrectly tagged as Direct - at the same time as the organic drop, Direct traffic doubled - it has since decreased back to just above the Direct baseline, however Organic has not improved
I'd just be interested to know if anyone has any experience with something similar happening and, if so, what do you think the cause was and how did you rectify it?
Thank you very much for your input in advance!

Thanks for the input Eric!
I've been looking into your suggestion of links being removed and it looks as though in a period of just under two weeks, we did lose about 40 referring domains - this started just before the end of the competition.
However, since then we've gained just under 200 more referring domains, so that doesn't appear to be the issue. According to Ahrefs, the number of keywords the sites ranks for did decrease around about the relevant time, but not significantly, so I wonder if it is more to do with the engagement side of things...
Would you suppose that after the increase in engagement due to the competition, visitors then get bored of using the site and decide to leave (potentially because of not winning?), causing sessions to drop down below pre-competition levels - which then might cause a decrease in the number of searchers looking for the site?
Many thanks for your help! -
We've seen this happen with a lot of sites, especially with sites that are related certain events. For example, a 5k race or a marathon website would suffer the same fate.
It's the drop in engagement on the site, as the competition is over so visitors have no need to go to the site anymore. Also, the site may have lost links pointing to the site. The site owner pointing links to you figured the competition was over so they removed the links.
I would take a look at the links to the site and look at the historical links (using Majestic.com) or see if you have a list of links from previous link evaluations--crawl those links and see if any of them have changed or been removed. If they have, you may be able to see if you can get those links back.

Changes to cookies, August 24 or 25? (organic search not being cookied?)
Hi folks. We've seen a precipitous change in the referral data that we're able to gather from cookies. Specifically: On August 24 or 25, traffic to our site that was cookied as coming from organic search dropped by ~25%, and traffic coming in with no referrer data at all (i.e., it appears to be "direct") rose by roughly the same amount. As far as we can see, we haven't changed anything in our systems that would have caused this (we're not just mis-reading the cookie info), so I'm looking for external reasons. Has anyone else seen this? Or have any ideas why it would happen?

Need help understanding what happened to our organic search.
I help run an ecommerce business that mainly runs on Google organic search (yes, I realize this is not a good place to be). Last April, we saw around 25-30% of our organic search cut. I’m pretty sure it was due to the mobile update but we had some changes in the past month or two before that. I’m looking for someone to review my analytics account and see what happened. Possibly this is called an audit? Also, we’re looking to ask some questions about long term strategy as we are thinking about a redesign and switching to a new platform. Maybe more content? Maybe more social?

Can't identify the real source of a goal because subdomains in GA
Hello, I have one domain for my website (www.domain.com) where I receive all the new traffic and a subdomain (billing.domain.com) for the billing system. Im tracking both in Analytics. I have a goal (new order) configured in the subdomain -billing system-. But when I want to track the source / medium of the goals (new orders) in billing.domain.com, always appears my main website (www.domain.com) as the referral. Now I added in Analytics: Admin > Property > Referral Exclusion List, the www.domain.com and domain.com. Do you think that now I can track the real referrer of the goals? Or should I do a more complex tracking setup with Tag Manager ( https://support.google.com/tagmanager/answer/6106951 ) to pass the session cookies from a subdomain to another one, just to identify the real source / medium of the visitor? Thank you 🙂

Can you re sit the Google analytics IQ test?
Damn I just failed the Google analytics IQ test with a score of 65% 😞 You need 80% to pass... My natural instinct is to resit but after 30 mins of googling around Ive got no answer to the following question: "Can you resit the Google Analytics IQ test for free or do you have to pay again". Any insights welcome...

Number of Visitor Entries to page via search engine
Hi, I wanted to figure out the most optimal way to track the number of visitors that comes to a specific page on my blog via search engine only. I know Google Analytics has a "top landing page" filter, but that includes all visitors that comes in directly or other channels. Is there a way to figure out how many visitors a certain page received that was generated through only search engine? Does SEOmoz have this capability?

Any updates regarding 'not provided' organic keyword referrals in Google Analytics?
I know that the encrypted searches done by people logged into their Google accounts is causing the error, is there any workaround or any update from Google as to IF they will give us our keyword data back? I'm currently losing data on about 20% of my daily searches . . .
