Case Study: Google Search Ads vs. Facebook Ads for a Small Local Business
For small businesses with limited budget, it can be hard to decide how to distribute your advertising budget. Money is tight, and a lack of time is often a problem.
Worse still is when you’re a new business fighting for visibility in the search results.
My client Kerry's Fresh, a local business offering fruit and veg delivery, wanted to increase their online presence, but also wanted to reach their financial targets. We had a hypothesis that Google search ads would be the better platform to capture leads compared to Facebook advertising. However, we were also interested in the additional value that could be gained from Facebook advertising, such as Facebook page likes and brand awareness.
In this case study, we will explore whether it’s worth investing in both search ads and Facebook ads for a small local business like this.
Note that these platforms are very different in nature, and a like-for-like campaign is not possible, but we’ll still attempt to compare costs and results.
The data we will be looking at is over six months, from 1st April - 30th September 2017.
The objective for both platforms was to gain website transactions. For our Google search ads, we focused on keywords with high intent. As this is not possible on Facebook, we set careful audience targeting based on customer personas, to show our ads to users who were most likely to convert. This targeting strategy was paired with engaging product images and calls to action.
For the search ads, we ran many campaigns, aimed at B2B and B2C users. Yet, on Facebook we focused on the B2C audience and continued to improve and update the Facebook ads frequently, so that they didn’t become stale.

The landing page used for both platforms was the same, as we designed a landing page with paid search in mind, which had minimal steps to complete a conversion.

When comparing the results of search ads and Facebook ads, we can conclude that for new businesses, paid search ads are the best way to spend their budget in the short term.
Google search: The pros
The data shows that it was 72% cheaper to gain a transaction with Google search ads than Facebook ads. The search ads had a much lower average Cost Per Acquisition of £30.72 over a six-month period; this is far lower than the CPA for Facebook ads, where we saw a very high CPA of £109.
*Conversions for Facebook were all online transactions. For AdWords, one conversion was from a phone call, the others were transactions.
Yet, when comparing all transactions from Facebook over the six-month period, the CPA is reduced to £23.30, and Facebook shows to be the most cost-effective platform, as the CPA was 24% cheaper than Google search ads.
Facebook ads: The pros
Without the investment in Facebook ads, boosted posts and competitions this low CPA would not have been achieved. From Facebook ad manager, we can see that running Facebook ads played a significant role in growing their Facebook presence.
During this period, the client’s Facebook page gained over 460 new ‘likes.’ With the addition of boosted posts and running a Facebook competition, the client gained nearly 200 shares and 6,177 link clicks to their website. We found that as the Facebook audience increased over time, so did the online transactions.
Google search vs. Facebook ads costs
When comparing CPC, the average cost per click for Facebook was 71% cheaper than Google search ads. With many competitors fighting for the same keywords in the SERPs, the average cost per click was £1.22 over a six-month period. Yet when targeting B2B phrases, the CPC was £2.06 for the average position of 2.6 in the search results.
One of the main differences between the campaigns was the spend. During this period, we spent less on search ads due to low search volume. Yet, Facebook would continue to spend the daily budget due to the nature of Facebook ad delivery and targeting settings.
Here you could argue that search ads are more cost effective, as Google Search ads will only spend the budget when keyword requirements have been met, yet Facebook continued to use the full daily budget if the audience requirements were met.
As mentioned previously, it’s hard to compare like for like campaigns between Google search ads and Facebook ads. Also, results may vary widely depending on your industry and business type. Yet, when we do compare Google search ads to Facebook ads for this particular client, the search ad campaigns were more cost-effective.
However, it’s important to consider the impact that the Facebook ads had on the overall success of the client’s Facebook performance.

Even though Facebook ads proved to have an expensive CPA for this client, I would not ignore the overall impact and brand awareness that can be achieved using the platform. We were able to reach more people who weren’t actively searching for relevant terms.
I recommend that SME’s invest the time and effort into Facebook, and consistently post and share content to develop their brand and online presence.
By testing and trialling both Facebook and search ads as part of the marketing mix, you can find what works best for you. I would also suggest having patience when it comes to social media advertising – the more you grow your following, the more success you’ll have.
