Now that RSAs (responsive search advertisements) have changed ETAs (expanded textual content advertisements) in Google Advertisements, it might be time to rethink your methods for optimizing advertisements.

Optimizing RSAs takes an entire totally different strategy than what most advertisers have been doing for years.

Whilst you’ll nonetheless need to use an identical methodology to determine what textual content variations to check, the best way you go about doing a take a look at that results in statistically vital outcomes has modified.

RSA Testing Is Completely different From ETA Testing

Advert testing used to encompass A/B experiments the place a number of advert variations competed in opposition to one another.

After accruing sufficient information for every of the contending advertisements, a winner could possibly be picked by analyzing the appropriate metrics.

A preferred metric to find out the successful advert used a mixture of conversion price and clickthrough price to calculate “conversions per impression” (conv/imp).

The advert with the very best price could possibly be declared the winner after sufficient information had accrued to permit for statistical significance.

This method for locating successful advertisements not works for 3 causes.

Let’s check out what these are.

Purpose 1: You Can Solely Check 3 RSAs Per Advert Group

Within the days of ETA advert testing, advertisers might increase their A/B take a look at into an A/B/C/D/… take a look at and maintain including extra challengers to their experiment till they reached the restrict of fifty advertisements per advert group.

Whereas I by no means met an advertiser who ran 50 concurrent advertisements in an experiment, I’ve seen many who examined 5 or 6 at a time.

However Google now caps advert teams at a most of three RSAs in order that already adjustments the best way issues must work in advert testing.

Purpose 2: You Don’t Get Full Metrics For Advert Combos

Do not forget that every RSA can have as much as 15 headlines and as much as 4 descriptions, so even a single RSA can now be answerable for producing 43,680 variations.

That’s way over the 50 variations of ETAs we had been allowed to check up to now.

So when a person sees an RSA, solely a subset of the headlines and descriptions submitted by the advertiser are literally proven within the advert.

What’s extra, which particular headlines and descriptions are proven adjustments from public sale to public sale.

When evaluating the efficiency of two RSAs to at least one one other, you’re actually evaluating the efficiency of 43,680 potentialities of advert A to 43,680 potentialities of advert B.

That signifies that even in the event you discover advert A to be the winner, there are a whole lot of uncontrolled variables in your experiment that invalidate any outcomes chances are you’ll discover.

To get extra helpful information, you’d have to take a look at the combos report which exhibits precisely which headlines and descriptions had been mixed for every advert.

However the issue with this information is that Google solely shares the variety of impressions.

And to calculate the successful advert, we have to find out about CTR and conversion price, each metrics that we not get from Google at this degree of granularity.

Purpose 3: Advert Group Impressions Now Rely As A lot On The Advert As The Key phrases

However perhaps essentially the most shocking factor of why advert testing methodology must evolve is that the outdated strategies had been in-built a world that assumed impressions solely trusted the key phrases of an advert group.

RSAs have challenged this assumption and now the impressions of an advert group can rely as a lot on the advertisements because the key phrases.

In Optmyzr’s Might 2022 RSA examine, we discovered that advert teams with RSAs acquired 2.1 occasions as many impressions as these with solely ETAs.

And no matter whether or not this dramatic enhance in impressions for advert teams with RSAs is because of improved advert rank and high quality rating, or whether or not it’s as a result of Google has in-built a choice for this advert sort, the tip outcome is identical.

The sandbox during which we play prefers RSAs, particularly people who comprise the utmost variety of property and that use pinning as sparingly as attainable.

So once we do trendy advert optimization, we should think about not solely conversions per impression but in addition the variety of impressions every advert can ship.

A/B Asset Testing With Advert Variations

Fortuitously, Google has thought of the issues RSAs launched for advert testing and has made updates to Advert Variations, a subset of their Experiment instruments, to optimize advertisements.

Somewhat than requiring the creation of a number of RSAs, the experiments function on property and permit advertisers to check three kinds of issues: pinning property, swapping property, and including property.

You’ll discover all of the choices within the left-side menu for Experiments.

Check Pinning

Pinning is a solution to inform Google which items of textual content ought to all the time be proven in sure elements of the advert.

The only type of pinning tells Google to indicate one particular piece of content material in a selected location. A standard use is to all the time present the model in headline 1.

A extra superior implementation is to pin a number of items of textual content to a selected location.

In fact, the advert can solely present one of many pinned texts at any time so it’s a solution to steadiness advertiser management with the advantages of dynamically generated advertisements.

A standard use could be to check three variations of a model message by pinning all three variations to headline place 1.

Essentially the most excessive type of pinning is to create what some have known as a “faux ETA” by pinning textual content to each place of the RSA. Google recommends in opposition to this as a result of it defeats the aim of RSAs.

In Optmyzr’s RSA examine, we additionally discovered that such a pinning can dramatically cut back the variety of impressions the advert group can get.

However considerably to our shock we additionally discovered that faux ETAs have larger CTR and better conversion charges than pure RSAs.

One concept is that advertisers who’ve spent years perfecting their advertisements utilizing ETA optimization methods have already got such nice advertisements that machine studying might have little to supply when it comes to upside.

To start out an advert take a look at with pinning, search for the Advert Variation choice to replace textual content after which select the motion to pin.

You may then construct guidelines for which headlines and descriptions to pin to a wide range of places.

For instance, you could possibly say that any headline that comprises your model title must be pinned to headline place 1.

One limitation is that you just can’t create an advert variation experiment that checks pinning for a number of places on the identical time.

Check Including Property

One other experiment out there with Advert Variations is to check what would occur if sure property had been added or eliminated.

This sort of take a look at is nicely suited to testing larger adjustments, for instance, to see what would occur in the event you included a particular provide, a special distinctive worth proposition, or a special name to motion.

You may as well use this to check the affect of Advert Customizers in your efficiency.

Some advert customizers out there in RSAs are location insertion, countdowns, and enterprise information.

Check Changing Property

The third and closing sort of advert take a look at supported in Advert Variations is to check what would occur if an asset was modified.

This sort of experiment lends itself to testing extra refined adjustments.

For instance, what could be the affect of claiming “10% low cost” somewhat than “save 10% at this time.”

Each are the identical provide however expressed in another way.

Advert Variation experiments routinely include correct measurement.

For instance, right here you see the outcomes of a take a look at we ran with pinning.

Statistically vital outcomes are marked with an asterisk.

Once you hover over the stats, extra particulars are revealed that designate the boldness ranges of the experiments.

From there, it’s a easy matter of a single click on to advertise successful checks to grow to be a part of your RSAs.

One thing to notice is that these Advert Variation checks are supposed to be completed on the marketing campaign degree or larger (cross marketing campaign).

At the moment, it isn’t attainable to run an advert take a look at for a single RSA or in a single advert group. Google has stated they’re conscious of this limitation and are working in direction of an answer.


As advert codecs in Google have modified, it’s time to additionally change how we do advert testing.

Advert Variations are a simple manner constructed proper into Google Advertisements to create experiments that work with property somewhat than total advertisements and you’ll even take a look at pinning.

Optmyzr’s most up-to-date RSA examine confirmed impressions now rely as a lot on having good advertisements as they depend upon having good key phrases, so working in direction of advertisements which have the appropriate mixture of not solely CTR and conversion price but in addition numerous high-quality impressions is the fashionable solution to optimize PPC advertisements.
