      We've noticed a 100% increase in our traffic over the last three days. However, the page views have not increased proportionately. The traffic sources seemed to be dispersed naturally. Could this be a Ddos in the making or some other type of attack as it seems unlikely that we suddenly started receiving thousands of extra visitors. Its a leading news website with a consistent heavy traffic daily which just doubled over the last three days. What should we be looking at?

        As you have looked at the traffic sources and they seem to be natural I would then look at what the visitors are doing on your site.

        Is the bounce rate up considerably? Has the time per visit fallen dramatically?

        If not, if the traffic seems to be coming from a natural spread of sources and the behaviour on the site of the visitors is normal then just be glad of the extra traffic.

          That's the thing...after a drill down, everything seems very natural...the IP sources are varied, the traffic sources have propotionately increased and the mapping also shows an increase in traffic from diverse locations. Analytics does not seem to indicate a particular planned trend...though the spike in traffic still feels a bit odd!

              Depending on your analytics package you should be able to look at information such as network and location of visitors and drill down into them to see if the traffic is coming from an unusual source. For example on a UK site I look after with a small local focus they have had a number of visits from Tawain via the Taiwanese Google site. This may give you some insights as to whether it seems to be a real bounce or something more sinister.

                Have you looked into the server activity log ? You may check the referer, the IP used and more. If this is a well done DDoS your servers should be down. Check the traffic : does the increase is a direct traffic ? Does it comes from search results or referring sites ?

                A DDoS has only one goal and will probably use a direct request. I doubt this is the case for your site.

                  If website users don't accept GDPR cookie consent, does that prevent GA-GTM from tracking pageviews and any traffic from that user that would cause significant traffic decreases?

                  I've been doing a lot research on GDPR impact and implementation with GTM-GA for clients, but it's been 12 months since GDPR has gone live I haven't found anything on how GA traffic has been impacted if users don't accept cookie consent. However, I'm personally seeing GA accounts taking huge losses in traffic since implementing GDPR cookie solutions (because GTM/GA tags aren't firing until cookies are accepted). Is it common for websites to see significant decreases in traffic due to too many users not accepting cookie consent? Are there alternative solutions to avoid traffic loss like that and still maintain GDPR compliance? It seems to me that the industry underestimated how many people won't accept cookie consent. Most of the documentation and articles around GDPR's start (May 2018) didn't foresee or cover that aspect properly, everything seems to be technically focused with the assumption that if implemented properly most people would accept cookie consent, but I'm personally not seeing that trend and it's destroying GA data (lost traffic, minimal source attribution, inaccurate behavior data, etc). Thanks.

                  Paid traffic or "Paid Search" is not showing in my Google Analytics

                  Hi, I have two campaigns running in Google Adwords or Google Ads now and I saw in Google Ads account that I had 5 clicks today (09/18/2018) but when I try to search for this clicks in my Google Analytics in ACQUISITION > All Traffic > Channels I don't find nothing about "Paid Search" or something like that. Bellow is a picture of my Google Analytics account to prove it. The accounts are linked and I can find the 2 campaigns in the Analytics. How can I interpret this picture? Where the paid traffic is showing? or not showing there? Thanks Leandro uvAtrsg

                  Why is Indeed.com traffic appearing as organic in Google Analytics?

                  A large number of sessions in my client's Google Analytics account appear to come from medium: organic and source:Indeed. Since I'm focused on SEO for this project, I'd prefer that Indeed be treated as referral traffic. Any ideas for fixing this issue? Also, and I'm sure the answer is no, is there a way to fix the past data in Google Analytics that has already reported Indeed as an organic medium?

                  We have a client that wants to apply UTM URL tagging to track local organic traffic in Google Analytics. Is there any benefit in doing this?

                  One of our clients requested that we apply UTM URL tagging to better track organic traffic in Google Analytics.   We found this to be an odd request because we are most familiar with UTM tracking for special campaigns (referral tracking, PPC, email tracking, etc). Is there any benefit of applying UTM tags to urls to analyze local organic traffic in Google Analytics?  Are there any resources out there about this? Thanks!

                  Referral Traffic from Google

                  Hello, I have a question about my company's new website. I've worked in SEO and studied Google Analytics results for a few years now but have never really come across something like this. I started in this position in January of this year and when I started breaking down the traffic sources in Google Analytics, I noticed most of the traffic was coming from Google.com as a referral source. I had never seen Google.com as a referral source before so I looked into options for what it could be. It was not a paid ad and our organic traffic was coming through in Analytics, Before I could get any further, our new website was launched (we switched CRM's to WordPress) and the referral traffic from google went from 2,966 in January of 2015 to 22 in February 2015. for more comparison, in February of 2014, the referral traffic from Google was 2,496. I expected a drop when we switched CRM's but we correctly re-directed all pages and created a new sitemap and our organic traffic is up since the switch (not enough to cover drop in referral). I thought at first this had to do with our Google sellers account being de-activated when we made the switch, but I quickly fixed this over a month ago and no change. I'm wondering if anyone has ever seen Google.com come through as a referral source in Google Analytics and if they we're able to figure out what it actually was. This would be a great help! Thank you, Alex

                  Finding an Explanation for a Massive Spike in Organic Search Traffic

                  Hi, I watch analytics on a website (for a friend's business) that is reasonably stagnant, which just experienced a massive spike in search traffic for no explainable reason. The organic search engine traffic had always been steady, but about two months ago, organic search traffic started rising slowly. I checked OSE & a few other tools, but couldn't find any massive source of gained links or other explanations - just the usual occasional blog post about the company. I got in touch with my friend to see if maybe they'd gone with a competitor or something else, but he also had no idea (and even if he wasn't being honest with me, we still should've been able to spot links or social metrics or something!) Then, yesterday, their organic search traffic just tripled. The crazy thing is, it's not from one keyword: Every search term, and (not provided) essentially went up 200-400%. And I have no freaking idea why. No large gain of links. No website editing. The only possible explanation I thought up is maybe one of their competitors got knocked out, but I doubt that would cause such a stratospheric rise. So figured I'd turn to y'all. Any ideas on what might be causing such wonderful results? Anyone have any good tips on figuring out why a website could all of a sudden be doing incredibly? Analytics chart is below for the curious, and thanks in advance for any ideas / tips! nQHrscw.png

                  Does traffic coming from Adwords increase overall Domain Authority or Page Rank?

                  If I'm setting up an Adwords campaign, will setting my homepage as the landing page boost my domain rank? and will the Page Rank of the landing page get boosted because of the high click rate coming from the Adwords campaign?
