Simply over a yr in the past, my position at Buffer shifted, and I grew to become a Progress Advertising and marketing Supervisor engaged on Buffer’s Progress Advertising and marketing workforce. This variation occurred at a time after we wanted to rapidly scale how we run experiments to start out in search of enhancements to their efficiency.  

Experiments are an essential element in advertising groups and are a confirmed technique for understanding the causal affect of a change and bettering advertising technique iteratively and rapidly. Not solely does operating experiments assist us acquire a significantly better understanding of what works and what doesn’t, it additionally helps us drive significant affect on our key metrics in a managed, measurable means.

For Buffer’s Progress Advertising and marketing workforce, operating experiments is key to the way in which we work. It is unlikely we’d make a change to our web site, emails, or advert campaigns with out first proving via an experiment that the change will result in extra conversions. We consider within the experimental methodology a lot that we’ve made it our aim to run 5 experiments throughout net, e mail, and paid advertising each month. Inside paid advertising, we’ve performed simply round 30 paid advertising experiments within the final yr alone, which have massively helped us make enhancements to our paid advertising channel technique, in addition to incrementally lower what it prices each time we purchase a brand new consumer.  

I personal and drive our paid advertising packages throughout Meta, Google, and some other channels we validate. Thus far, I’ve run 25 experiments in our Adwords account. On this article, I’m sharing how I give you concepts for experiments and what I’ve discovered thus removed from operating these experiments.

The 4 levels of a profitable advertising experiment

For our workforce at Buffer, the experiment lifecycle course of if 4 levels. They’re:

Analyze: Reviewing knowledge for insights and alternatives throughout the funnel. Establish the place there are current friction factors that maintain again our customers from changing.

Ideate: Generate as many experiment concepts and hypotheses as potential that might resolve the newly discovered friction factors. Every thought ought to include the next particulars:

  • The core speculation, your assumptions, and studying targets
  • A quick description of the experiment thought and of the variant
  • How we’ll measure success, and which metrics will likely be affected
  • An ICE Ranking (extra on this within the subsequent level)

Prioritize: We assess all of our concepts by leveraging an ICE scoring model. This helps us prioritize all experiment concepts in our backlog previous to committing to them. It is a essential step as there are actual alternative prices with what we select to check, as each experiment we are saying “sure” to means we are saying “no” to a different.

Take a look at: Launch the experiment and let it run till we attain a big statistical distinction. We intention for 95 p.c confidence earlier than declaring a winner and normally let the experiment run for about two weeks (one cycle).

Then the cycle begins once more! Step one is to investigate the outcomes from the check and take away learnings that we are able to implement into our subsequent experiment.

There are quite a lot of sorts of experiments a Advertising and marketing workforce can use, however the most common one we use at Buffer is A/B testing.

A/B testing is a simple option to check a speculation by evaluating two choices: possibility A, or the management, and possibility B, or the variant. It’s a randomized check the place 50 p.c of individuals see one possibility, normally no matter is at present operating (management), whereas the opposite 50 p.c see one other new possibility (variant). This kind of check is very helpful for evaluating two variations of an advert, touchdown web page, e mail, or homepage.

My course of for arising with new experiment concepts

My workforce works in two-week cycles, which implies that firstly of every cycle, we plan and prioritize the duties that we have to full by the top of the cycle. Conducting an experiment matches up completely with that timeline.

On the primary or second day of the cycle, I analyze the info, jot down experiment concepts, re-prioritize, after which launch some new experiments.

At the beginning of the next cycle, I shut down the experiment, extract insights, after which use these learnings to give you extra experiment concepts. Then, we undergo the identical course of once more.

There are two methods I give you new experiment concepts:

  1. Analyzing the efficiency of the Adwords campaigns to search for friction factors.
  2. Extracting learnings from the earlier experiments and making use of them to new experiments.

Right here’s extra about every of those:

1. Search for friction factors

I sometimes like to check the marketing campaign’s efficiency with one another, in addition to the present time interval with the earlier interval, to see the place there have been will increase or decreases in both Search Impression Share, Click on-By way of Price, or Conversion Price.

When taking a look at these efficiency metrics, I have a look at ratios as an alternative of absolute numbers as a result of they assist me perceive traits and adjustments in efficiency higher, plus they normalize knowledge throughout campaigns of various sizes or budgets.

Typically, ratios associated to clicks, like Click on-By way of Price (CTR) and Value Per Click on (CPL), will inform you that there may be enhancements made to your advert textual content.

Ratios associated to your conversions, like Conversion Price and Value Per Acquisition, will inform me there are optimizations that may very well be carried out on our touchdown web page.

Identical as for advert textual content enhancements, I’d have a look at the touchdown pages with the very best conversion charges to get inspiration for brand new experiment concepts.

Listed below are another methods you’ll be able to enhance your Conversion Price:

  • Optimize your touchdown pages by matching the copy and supply to your advert textual content
  • Make your supply extra compelling

Lastly, Search Impression Share tells you the share of impressions your adverts obtained out of the entire impressions they had been eligible to get.

When you’ve got a low Search Impression Share, it possible implies that your adverts aren’t aggressive sufficient within the auctions, your key phrases aren’t related, or your price range and bids may be too small.

Listed below are some methods you’ll be able to enhance your Search Impression Share:

  • Enhance your price range
  • Enhance your bid quantity
  • Optimize your key phrases by turning off those that aren’t performing properly

2. Apply insights from earlier experiments to new experiments

Previous experiments can inform you quite a lot of tales about what’s profitable and what isn’t–all it’s a must to do is undergo the numbers to search out these tales. I continuously undergo the outcomes from previous experiments to search for what we modified and the way it carried out.

This apply retains paying off. Just a few weeks in the past, we ran an A/B check for a particular marketing campaign the place I made updates to our touchdown web page and advert textual content to raised emphasize Buffer’s free plan. My speculation was that the Value Per Acquisition (CPA) would lower by 10 p.c with these adjustments.

The variant marketing campaign ended up outperforming the management marketing campaign, leading to a seven p.c lower in CAC and a six p.c enhance in conversions.

I took these learnings and utilized them to a different marketing campaign and ended up with the variants successful over the controls as properly.

7 classes discovered from operating 25 Google Advertisements A/B exams

By way of all of this experimentation, I’ve discovered quite a lot of classes. Listed below are seven key takeaways from my expertise conducting 25 Google Advertisements A/B exams:

1. Take a look at advert textual content, key phrases, and squeeze web page copy concurrently ✅

I used to conduct experiments that solely A/B examined one variable, i.e. solely advert copy, solely touchdown web page adjustments, or solely key phrases. Proper from the beginning, I seen that every time I examined just one variable (i.e. solely advert textual content), with out making that change throughout the complete marketing campaign, the variant would typically lose out towards the management.

With time, I discovered that when conducting an experiment, it’s greatest to check advert textual content, key phrases, and touchdown web page copy concurrently. Why is that? It’s key to match the touchdown web page to the promise of your advert, simply because it’s essential to make sure your adverts match the intent of the consumer’s search question. Due to this fact, by utilizing your key phrases in your advert headlines, advert descriptions, and touchdown web page copy, you present customers that your advert is instantly related to their search and that the touchdown web page is related to the advert they clicked on.

For example, in the event you’d prefer to A/B check the impact of including the sentence “14-day free trial” to your advert textual content, you also needs to embrace that sentence in new key phrases, in addition to add that sentence to some locations in your touchdown web page fairly than simply add it to your advert textual content. This can make for a way more profitable experiment.

2. Keeping track of what your rivals are doing is vital ✅

Staying updated along with your rivals’ adjustments and updates can expose new alternatives in your personal technique. For example, on January 23, 2023, we seen quite a lot of chatter about Hootsuite on Twitter about the truth that they’ve determined to discontinue their Free plan on March 31, 2023. With Hootsuite’s removing of their free plan, we knew that it will lead an increasing number of folks to seek for free, beneficiant options; we additionally knew that we had been completely positioned to draw these folks to Buffer.

With this in thoughts, it made sense for us to extend our budgets for our competitor marketing campaign, which particularly focused key phrases like “free hootsuite options” and “free model of hootsuite.” Along with this, we additionally started to check the efficacy of mentioning our free plan in our different campaigns and located success with that as properly.

You too can search for traits in your competitor’s advert copy and touchdown pages to encourage your personal experiments.

3. Use the highest-converting key phrases throughout your campaigns ✅

Analyzing our top-performing key phrases has given us essential insights into what phrases resonate with our viewers. This generally is a helpful technique to information the creation of advert textual content, touchdown web page updates, and even new campaigns.

For example, a number of months in the past, I sorted our high key phrases by lowest Value Per Lead (CPL) and located these key phrases to be the commonest:

  • scheduler was present in 12 of our high key phrases
  • tiktok was present in 9 of them
  • free was present in seven of them
  • Instagram was present in six of them
  • instruments was present in 5 of them
  • viral and hootsuite was present in three of them

Primarily based on this discovering, we ended up operating a collection of experiments that A/B examined the addition of the phrase “free” in key phrases and duplicate. This was a serious discovering for us as we had been capable of massively enhance our Conversion Price just by selling our free plan.

4. Make the advert extra relatable by mentioning the nation they’re positioned in ✅

We seen that by including country-specific references in our advert copy, we made our adverts extra relatable and fascinating, which led to higher-quality advert rankings and elevated impressions and clicks.

For example, in certainly one of our A/B exams for a marketing campaign in Australia, we added Australia-specific references. The management marketing campaign had no references to Australia, whereas the variant included Australian references within the advert textual content, URL, headline, and buyer testimonial.

Right here is the landing page of the control:

Right here is the landing page of the variant:

By constructing the adverts round a particular nation, we elevated click-through charges and conversion charges, which implies that we had been capable of join higher with the folks seeing our adverts.

5. Observe an iterative course of for A/B testing ✅

Working advertising experiments is an iterative course of, with every check constructing upon the outcomes of the earlier check. Actually, even a failed check is a chance to know what went mistaken and guarantee these errors aren’t repeated. By making use of the insights of your experiments to the subsequent ones, you’ll be growing the probability that your subsequent experiments will succeed. I do that by writing a abstract of the outcomes inside the temporary on the finish of every experiment, which features a conclusion and suggestions for follow-up experiments. I additionally prefer to maintain a operating doc of insights from the entire experiments we’ve run. It’s useful to have the ability to return to that doc to extract new concepts for upcoming exams

Lastly, don’t maintain all this data simply with the folks you instantly work with. I typically share my learnings with different groups, particularly the Product workforce and the Product Advertising and marketing workforce, as they’ll apply quite a lot of the insights to their very own experiments, campaigns, and product options.

6. Leverage Responsive Search Advertisements ✅

With Google’s responsive search ads feature (RSAs), you’ll be able to create an advert that adapts to indicate extra related messages to customers. This function makes use of machine studying to find out the best-performing mixture of headlines and descriptions to current to a particular consumer.

I discover this function to be extremely profitable as a result of it takes the burden of testing off of the advertiser, permitting for extra effectivity and extra time saved. That is additionally prompt by Google, as they point out that RSAs “could enhance your marketing campaign’s efficiency.” Probably as a result of Google makes use of machine studying to find out the perfect mixture of headlines and descriptions, which ought to, in concept, enhance advert relevance and efficiency.

The opposite wonderful thing about responsive search adverts is that Google will present headlines and descriptions which can be extra related to the consumer’s search question, thus providing a extra customized expertise.

7. Embrace “Jobs To Be Finished” and benefit-focused copy throughout your adverts and touchdown pages ✅

We have discovered that utilizing copy that focuses on the advantages of our product and on the “Jobs to Be Finished” framework performs properly in each adverts and touchdown pages.


‘Jobs To Be Finished’ is a framework used to raised perceive what prospects’ particular targets or “jobs” are. To be taught extra concerning the framework, take a look at this video that includes Clay Christensen.

This kind of copy instantly addresses buyer wants and speaks to how our product can resolve their issues.

In my expertise, knowledge factors in advertising are extra than simply numbers; they inform a narrative, revealing insights and classes that may information strategic selections. As entrepreneurs, our position includes studying this knowledge, extracting these narratives, and regularly testing and refining our methods.

We’ve been capable of attribute a few of Buffer’s latest progress to this experiment-first strategy. The extra we check, the extra we perceive our viewers, thus enabling us to constantly refine our advertising methods for fulfillment.

I hope these classes will help you with any paid advertising or experiments that you simply implement into your personal advertising methods.
