Diagnosing Traffic Drops Using Google Analytics

It has happened to every marketer out there – you are just going about your daily reporting when you log onto Google Analytics and see an unexpected, and noticeable, decline in traffic.

First off, don’t panic. I know you may feel betrayed by Google Analytics for delivering the bad news, but don’t shoot the messenger. At that moment, it is your most powerful tool to decode the reasons for the dreaded traffic dip. By combining the features from Google Analytics and Google Webmaster Tools, you can quickly and effectively pinpoint the culprit, or culprits, behind your traffic drop.

Want to diagnose the cause of your traffic drop? Read on and get your web traffic back on track.

Step 1: Look at the Traffic Drop

Okay, you’re probably thinking: “Of course I looked at the traffic drop! That’s how I knew my site had a decline in visitors!”

Yes, but this means you should be thinking critically about the drop by asking yourself these questions:

  1. “Is the decline a sharp, sudden drop-off, or a slow and steady decline?”
  2. “Did the traffic only dip for a few days?”
  3. “Does it look like the traffic is beginning to recover on its own?”

The two photos below show the difference in a slight fluctuation in traffic and a sharp drop-off.



Taking 10 minutes to really look at your Google Analytics line graph can set you on the right path to identifying the reason behind the drop. For instance, if the drop was sharp, sudden, and isn’t recovering you could be suffering from a Google penalty. However, if the dip only lasts a few days and looks like it’s recovering on its own, your site may have just had connectivity issues that were fixed over a few days.

Step 2: Identify Your Traffic Sources

When your traffic takes a dive it’s important not to solely focus on the numbers. You need to dig into where you are losing traffic by looking at your traffic sources. There are 5 main types of traffic sources, including:

  • Direct – visitors that land on your site either by typing in the URL directly into their search bar or by clicking on a bookmark they have saved to get directly to your site
  • Organic – visitors who arrive at your site via a search engine. In my experience with clients, Google is almost always the most popular organic search engine, and usually monopolizes around 90% of search users
  • Paid – visitors that land on your site because of paid advertisements such as banner ads or Google AdWords
  • Referral – traffic brought to your site by your “referral network,” which are any partners who link your website on their own websites
  • Social – users who land on your site through social media platforms such as Twitter, Facebook, or Instagram


Once you figure out what types of traffic have dropped, you can begin to troubleshoot the drop. For example, if the majority of your traffic used to be Direct but has now fallen off, it is possible that there has been a change in your usual client landscape. Perhaps a competitor site has just launched a widely publicized campaign and your users are heading to their site.

On the other hand, if most of your traffic has been Organic and now you see a sudden drop, you may have been hit with a Google Penalty. These types of penalties can be devastating to your site traffic, and are pretty clear to see if the decline is sudden and significant. You can confirm whether or not you have been hit with a penalty by checking your Google Webmaster Tools account for a penalty notification.

Step 3: Be Aware of New Users vs. Returning Users

It is just as important to know who your users are as where they are coming from.
Depending on which type of user has declined, you can isolate certain reasons for the traffic drop.


For instance, if new user numbers have taken a hit there could be an issue with how users are searching for your site, or how it is appearing on Google. This may mean it’s time to do some new keyword research or it could indicate a Google penalty.

However, if returning users have declined it could indicate an issue with your site structure and ease of use for your users. Maybe the site is reporting multiple 404 Not Found errors or the loading speed of your site is too slow, so users are leaving due to a poor experience.

Step 4: Zoom Out

It’s vital to look at the big picture when it comes to traffic drops. Head over to your date range and really zoom out. Look at the past 6 months, or year even, to see if a traffic drop had occurred during a similar time in the past. You can compare time periods using the compare tool in the Google Analytics calendar, which lets you look at previous weeks, months, or similar time points in the past year in cases of seasonality. This allows you to see any trends or notable differences in user behavior or traffic sources.


One client of mine happened to see a steady traffic drop between May and July of this past year. They were extremely concerned as to why their faithful returning users were suddenly not visiting their site. I began to investigate by isolating the decline to direct traffic and returning users, but I still couldn’t pinpoint an exact reason behind the drop.

However, once I zoomed out, I saw that this same traffic drop always occurred during the summer months, and recovered by the end of September. We were then able to conclude that the drop was due to regular seasonality, which made perfect sense since their product was an educational tool.

Bonus Step: Don’t Forget About Webmaster Tools!

The combination of Google Analytics and Google Webmaster Tools can be a very powerful thing. Google Webmaster Tools has a messages tab that alerts you to any harmful activity or malfunctions on your site.


You should make it a habit to check on both your Crawl Errors and HTML errors. Both of these reports notate the amount of internal errors your website may have. If your site is reporting a hefty amount of errors, it could be impacting user experience. This could cause new users to be deterred from your site (since it seems unreliable or hard to use) and could drive even faithful users to competitor sites.

It is also important to keep an eye on your top performing keywords. If you check out the “Search Analytics” tab within your GWT account you can see if your high volume keywords have declined in search rankings. If you see that your high volume keywords have dropped in ranking that could be the culprit behind any decline in organic search traffic to your site.

Survive Traffic Drops With the Right Tools

Traffic drops are never fun and, if left unaddressed, they can be extremely damaging to your business. However, with the right tools and a systematic approach to uncovering the reasons behind a drop, you can survive any dip in traffic. So, next time you see the dreaded decline in traffic, reach into your survival kit, use Google Analytics as your weapon, and restore your site to glory.

  2. Thank you Brittany, I am facing a dramatic drop on my site, and its been a nightmare of a week. Thanks you pointed out some of the issues I was facing and am working on solving it.

  3. One more thing Brittany, I found out that my GA code was not right on WordPress and changed it back to normal, but my organic search is way low by 75%, is that because the tracking code was wrong or did I really got penalized?

  4. Dean Ethridge Sep 16, 2015 at 12:20 am

    I’ve been trying to figure out my issues as well. It’s on two sites after a host transfer, database nightmare. I hope it recovers soon. Thanks for the post

  5. Thanks, Brittany,

    I discovered that my GA code was not right on WordPress and transformed it back to typical, yet my natural hunt is route low by 75%, is that in light of the fact that the following code wasn’t right or did I truly got punished?

  7. @ Brittany

    This is good information. My traffic drops continuously. Can you please suggest me some good ideas to increase my traffic and decrease my bounce rate?


    • Brittany Pennellatore Sep 13, 2016 at 11:18 am

      Hi Tina,

      My recommendations on how to increase traffic would be based on what your business is and how your set is site up! But for bounce rate, I always suggest that you point your users to different pages on your site (ie when they arrive on a blog post, point them to another article or helpful download – it will keep them exploring your site!). Also make sure your site is very user friendly and clean in terms of design. If a site looks complicated, or broken, a user will likely bounce off the site without clicking around much.

    I’ve been attempting to make sense of my issues also. It’s on two destinations after a host exchange, database bad dream. I trust it recuperates soon. Thnx for sharing

  9. Eureka Forbes Feb 29, 2016 at 11:00 pm

  10. This is the type of CSI level analysis I live for. Great post. Thank you for sharing.

    • Brittany Pennellatore Sep 13, 2016 at 11:08 am

      Hey Steve,

      Apologies for the delayed reply! I’m so glad you enjoyed the article, and found my tips helpful!

  11. This is very useful information, however having used the tools above and my own experience and knowledge, I still cannot determine the cause of loss of traffic on the site I run.

    • Hey Cody,

      Apologies for the delayed reply! I’m happy to hear you found the information useful. Unfortunately there are a lot of issues that can impact traffic, and some of them can not be easily seen in your analytics. I’m happy to chat about your website if you’d like to shoot me an email!

  12. Girish Gullapudi Oct 02, 2016 at 7:03 am

    For our website, only Organic traffic suddenly dropped by 80% over a period of 1 month. However other traffic sources are at same level. Could anyone please help trouble shoot.

    • That most likely means you have some sort of penalty.

    • Hi Girish and Everyone,

      Most of the times, it happens when the Google Analytics tracking code is implemented twice. Google fires a pageview when a visitor lands on the page. If two GA snippets are implemented and someone lands on your page, they cannot track the bounce since they think the other snippets’ page view counts as an interaction and the bounce rate drops to nearly nothing.

      Have a look at your page source once!

    Hi Brittany,

    This is really helpful information! I’ve only had my website up for around 2 months. I began getting around 189 views in a day, but not I’m struggling to get 20. I haven’t changed anything particularly but my ‘social referrals’ have dropped significantly. Really hard to tell what is going on so I think it’ll be visiting this page frequently!

    Thanks for your informative article!

  14. We noticed sudden drop in our traffic by 24th January and has no clue what happened, However I found high number of 404 errors in webmaster report and one of our rank page was there, I changed the url without using 301 redirection. Please suggest what should I check further to identify the exact reason.

  15. Hi Brittany, great article, and very useful. I have followed your advice but still cant seem to get an answer. Our site was getting a traffic from a specific country (Kenya) and then it suddenly dropped of to basically 0 traffic. About 65% was organic, so I assumed it may be a penalty. On Google Webmaster there is not notifcation of a penalty, and I cant see any Algorhythm change around that dat (28/29th Sept 2017). I would appreciate your advice if there is anything else that can be checked? Many thanks Paul
