It’s hard to believe that 2022 is right around the corner. 

With the second year of life during a pandemic behind us, let us reflect on some of the biggest internet trends we encountered so that you can better prepare for what’s coming next. 

Using Similarweb Digital Research Intelligence, we explored the biggest digital trends of the past year in terms of keyword searches, website traffic, and audience engagement. We focused on the events people couldn’t stop talking about, products that trended, and global market patterns likely to stick around post-pandemic.

2021 Trends Infographic

1. Pop culture is still king queen – the Megan and Harry interview

Celebrities are fascinating. Their lifestyle, culture, and stardom are often front-page news and the subject of countless social media frenzies. And the rise of popular platforms like Instagram and TikTok means an unprecedented view into their lives. 

So when Meghan Markle and Prince Harry sat down with Oprah on March 7, 2021, the internet was chomping at the bit to hear what the couple would say and which family secrets they’d spill. 

Viewers all over the world wanted to watch the interview, but since had exclusive airing rights within the U.S., many needed a VPN to do so. 

Audiences in the U.K. who didn’t want to wait to watch the interview until it aired locally, turned in droves to VPN websites as a solution. So much so that traffic for three top VPNs soared exponentially during the first week of March.

Traffic growth March 1–March 7, 2021:

Although just a one-off event, this huge pop culture moment offered ample opportunities for any company with an online presence to make some noise. Our data coverage of the topic was one of the most shared articles of the year.

2. People are more interested than ever in climate change

Climate change was one of the most talked-about (and searched) subjects this year, as internet users express more interest and concern than ever in the global phenomenon. In April 2021, climate-change-charged keywords peaked at 145,500 searches, and web traffic to environmental sites escalated dramatically.

In addition, visits to environmental education websites experienced nearly 90% growth year-over-year (YoY). The data doesn’t lie: educational and consumer trends both point towards a greener mindset. Companies that are able to tap into this – whether it be through eco-friendly business practices or awareness campaigns – will come out ahead in 2022.

3. Electric transportation races ahead 

Building off of the consumer’s growing eco-consciousness, there’s been a clear shift this year in preference towards electric bikes as alternatives to buses, cars, and other smog-producing forms of transportation. This change is reflected in search behavior – both on Amazon on-site search and search engine traffic to leading e-bike brands’ websites.

A deeper dive shows how, a major player in this space, has seen traffic around electric bikes increase by four times over the last year. The growth peaks both in August 2020 and February 2021 could be attributed to well-placed advertisements or marketing campaigns that capitalized on the growing interest in this category.

4. Our favorite in-person activities are back 

Although we’re not back to normal yet (and maybe we’ll never be), COVID restrictions eased throughout 2021, and people returned to in-person gyms and fitness classes for the first time in over a year. And how did they find their new gym? On the internet of course., a popular site used for booking in-person fitness classes, hit its highest level of traffic since 2019 at 784,700 in May 2021. This is 113.4% higher than in May 2020 in the middle of the pandemic.

Restaurants and dining were other luxuries that we had to temporarily say goodbye to for most of 2020. While grocery and food deliveries soared, reservations for in-person dining dropped drastically. However, after almost a year of cooking for ourselves at home, it’s finally time to go out and grab a bite at our favorite spots. 

Both and, two go-to websites sites used for booking dining reservations, have hit their highest traffic levels since before the pandemic at 2.6 million and 9.5 million in May 2021 respectively. For, this was a whopping 2,015% higher than the year before.

5. No live audience, no problem  

There was a ton of pent-up anticipation for the 2021 Summer Olympic Games in Tokyo. And when the Olympics Committee announced that there would be no in-person fans allowed for health and safety concerns, millions tuned in online to watch their favorite athletes and read recaps of the competitions they couldn’t see live.  

Using search interest analysis for 90+ Olympic-related keywords in July, we ranked the countries with the most dedicated fans. 

The U.S. set a record for its average monthly search volume, clocking in at 4.9 million. Silver-medalist India drove 2.2 million Google searches, and the U.K., our bronze-medalist, put up a score of 886,800. 

Another tip for you for the year ahead – include remote or virtual options for any event you’re planning. Consumers have adapted to our new reality and will expect these types of options in the future. 

6. Drone delivery takes off  

We’re officially living in a SciFi movie and drones are playing a huge role in shaping the future of logistics and eCommerce. 

With more and more consumers buying online, whether it be groceries, clothes, home goods, etc, companies are looking for fast, reliable, and cost-effective shipping solutions. Drones are quickly becoming everyone’s go-to. 

In fact, as the demand rises, drone delivery service Wing (operated by Google’s parent company, Alphabet) has recorded strong growth in the last 24 months. Year-to-date (January 2021 – August 2021), the website experienced a 12% YoY jump in the U.S. market, and an incredible 111% YoY surge in visits from Australia.  

Although it’s not mainstream yet, keep an eye on this field, especially if you are in a line of business that requires shipping goods directly to consumers. You don’t want to be stuck in the past (or really on the ground) if all your competitors start offering drone deliveries to customers.

7. TikTok revives retro brands 

TikTok is one of the most impactful marketing tools right now, especially if you are targeting Gen Z or millennials directly. One viral video and you could be the talk of the down with the product that everyone must-have. TikTok has become so powerful that even brands we consider retro are rising to popularity again after small cameos on the social media platform. 

In August 2021, after being featured in a TikTok on the benefits of sour candy for panic attacks, Warheads experienced a significant brand lift which resulted in an uptick of over 2,239% in revenue on Amazon.

Abercrombie & Fitch experienced similar growth and popularity which can be attributed to TikTok users’ obsession with a particular pair of jeans the retailer sells. As users tried to score a coveted pair of pants, traffic to grew nearly 9% YoY in Q3 2021, while visitation to its major competitors declined.

8. Companies prep for a cookieless future 

A cookieless future is upon us. And even though Google decided to postpone its sunsetting of 3rd party cookies, this change will happen and when it does it will profoundly impact how publishers, media, and agencies can capture ad spend.

As we shift further into a digital-centric world that will rely less on cookies, the question we need to pose ourselves is “what is the future of advertising?” Well, what better way to answer this question than to go back to our roots and focus again on product placement 

Forward-thinking brands are using this time to develop direct relationships and communicate their unique value to customers before cookies disappear – Sweet Baby Rays BBQ Sauce did just that in October 2021. 

Although Mark Zuckerberg isn’t your typical influencer, subtle product placement can help catalyze a simple product’s traction in the market. Sweet Baby Rays was already on a positive trendline upwards at the beginning of the year, but with a subtle placement in the background of Zuckerberg’s Meta announcement, the climb isn’t slowing down.

Digital advertising is going to change dramatically as we shift towards a cookieless world, so brands will have to figure out creative strategies to stay relevant in a competitive market.  

9. #SUEZBlocked: Readers want news on-the-fly 

Between March 23 – 29, 2021, a huge shipping container was blown off course and became stranded in the Suez Canal, blocking any access or trade through the waterway. 

Like any global event, the internet jumped on the discussion resulting in 133,000 shares of the hashtag #SuezBLOCKED and more than 145,200 interactions on Twitter. 

People were googling the event so much that the search term suez canal grew 200% YoY.

Trending keywords that people were most likely to search included suez canal blocked, suez canal ship stuck, suez canal crisis, and suez canal blockage.

Publishers and media websites were able to capitalize on this buzz and fast. Prior to the event, organic search competition related to the Suez Canal came almost exclusively from reference materials or search engines, such as,,,, and

However, in March 2021 there was a noticeable transfer of power. Eight of the top 10 media websites won significant traffic distribution for “suez canal,” one of the first times that publishers stole such a significant amount of traffic away from the reference websites for this category.
