5 Marketing Trends That Didn't Go Well in 2014Ditch these flops as we head into the new year.

2014 was an innovative year for marketing, but let's face it: a lot of trends didn't pan out. In the interest of cleaning our slate for 2015, it's time we review these failed strategies and tools that will soon be irrelevant.

Mobile app usage isat an all-time high. Time is precious and competition is too fierce to maintain marketing strategies that don't work. Here we present five trends that flopped in 2014 and won't be making a comeback anytime soon.

1. QR codes

QR codes are going to be a meaningless time sucker in 2015 because the majority of mobile users don't have the ability to scan these codes. In 2013, only19.1 percentof consumers had ever scanned a QR code, and these numbers have not increased significantly. The issue is that mobile users must download a specific app just to scan these codes. It's an unnecessary stumbling block that hinders your call to action and frustrates your audience.

The only viable solution to this problem would be preloading QR code-reading technology on smartphones. Apple and Google's Android alone make up93 percentof the smartphone-platform market, so unless both companies make that decision, QR codes are effectively doomed.

2. Auto-posting

We're all guilty of this. When we're pressed for time, auto-posting makes it quick and easy to post the same message across all of our social-media networks. However, each social network serves its own unique purpose and attracts a unique audience. The same message usually doesn't work on four or five different networks.

To keep our content relevant, we have to tailor it specifically to the network we're posting to.

3. Viral videos

A few months ago, you may have seen thisvideoof strangers kissing for the first time. It probably cluttered all your social-media feeds. What you may not know, however, is the ulterior motives of this viral video. Did you know that all of the "strangers" in this video were actually actors hired by Wren Studios?

The original video racked up over 41 million views in just three days, so you would think this is the epitome of a successful viral video. However, when Wren Studios released a follow-up video with CEO Melissa Coker, revealing that the video was an advertisement for the new 2014 collection, it was seen by merely 100,000 people. The tweet sent out by Wren Studio announcing the video got just 450 retweets.

如果你问一个随机的人如果他们看过video of strangers kissing for the first time, they may have seen the video, but few of them will make the connection with Wren Studios. The moral of the story: unless your viral video is extremely well executed and tied to your brand, it's not worth your time, money or effort in 2015.

4. Over-optimizing

Search optimization is going to be as important as ever heading into 2015, but stuffing as many search-worthy words and key phrases into your blog post or website will no longer land you at the top of every search engine.

Google is constantly tweaking its algorithm and the old "filler with no substance" method will no longer cut it. Nearly90 percentof all queries were affected by Google's new algorithm, nicknamed "Hummingbird," and future changes may have an equally dramatic impact.

The new approach is to focus on conversational queries: the questions that consumers want answers to. Think about potential questions your customers could be asking and concentrate on answering those specific questions in your web post instead of trying to fill your posts with keywords.

5. Responsive web design

Responsive web design (RWD) refers to a website that can resize itself depending on the device it's being accessed from. In general, RWD is time consuming and costs a lot of money. Unless your non-responsive web design is deemed unreadable by your readers, your return on investment from RWD is going to be close to zero. Sites that rely heavily on images or sites, such as Google Maps, are exceptions and may require RWD because desktop versions can't physically be contained by mobile devices.

Another argument for using RWD is that it significantly decreases your load time on mobile devices. This isn't exactly the case. Most designers simply hide elements to reduce loading times on responsive platforms, but hiding elements doesn't prevent them from loading and sapping resources.

A good alternative to RWD islazy loading, which is a non-responsive way to load all of your resource-intensive elements last. The other option is to just create native mobile apps for mobile users. Apps will provide a much better mobile experience than RWD.

It's time to dump the trends that failed in 2014 and embrace what awaits us in 2015. Trial, error and time have shown us what works and what doesn't. Bid these trends farewell, and free up your time and budget for innovations worth pursuing.
