8 Common Google Ad mistakes that lead to poor performance & profitability

We regularly audit Google Ads accounts for new prospects, which have either been managed by internal teams or other agencies.

Whilst the general quality of account structures and strategies are comprehensive and well thought through, we still find that some accounts lack basic fundamentals which lead to poor performance and/or lack of sustainability.

We understand that managing PPC campaigns can be daunting, especially in industries where competition levels are high and therefore marginal gains play a major part in gaining successes. By avoiding these 8 common mistakes, you can accelerate your PPC success and growth.

1. Lack of Keyword Research

If you fail to prepare, you are preparing to fail. Keyword research should be the starting point for most campaign types, even if the campaign type isn’t inherently keyword targeted, such as Shopping or Performance Max. This is because it can both inform keyword ideas to target directly via search campaigns, as well as informing on page content for the product or service in question.

We often find accounts only adopt top level keywords with either a “phrase match” or broad match keyword strategy in a single ad group, meaning that the account shows for a huge variation of keywords which are not relevant to the business. Moreover, there is lack of ability to show very specific ads for very specific user queries, in favour of showing generic ads to a wide range of users with various intent.

By conducting thorough keyword research, campaigns and ad groups can be segmented into logical themes, with more control of which ads show to which users, as well as more insight into individual keyword performance. Moreover, if some keyword themes perform less than others, they can be optimised more effectively in their own ad group and in some cases, stripping them into their own campaign can be wise, in order to not affect the performance and budget depletion of better performing “bread and butter” search terms.

2. Search Term Reports Under Utilised

It’s quite common to utilise “phrase match” and broad match keyword matching types as we have discussed, which in turn show ads for your target keywords and variations thereof. Because Google will show ads for variations of your keywords, it’s important to comb through search term reports to assess which variations of your keywords your ads have shown for.

Within search term reports, you can then add or exclude keywords depending on their relevancy to your business and goals.

Google doesn’t understand your business inside and out, so keyword variations are often not related and therefore spend can be wasted on irrelevant users clicking. By adding and excluding the keyword variations your ads are shown for, over time you can hone down on user relevancy and utilise budgets more efficiently.

3. Inadequate or Outdated Bid Strategies

There are a wide range of bid strategies and over time, they have become more comprehensive and sophisticated. We often find that accounts utilise outdated strategies such as Manual CPC or Enhanced CPC, which generally discount Google’s machine learning abilities and therefore don’t hone down on efficiencies, the same as a bid strategy that aligns more with your business objectives.

Instead, we would typically utilise bid strategies that are specifically tailored towards business goals, such as “maximise conversion value” with a target ROAS (Return On Ad Spend) for an e-commerce business, or “maximise conversions” with a target CPA (Cost Per Acquisition) for lead gen businesses.

There are of course a wealth of other options, for example if you wanted to gain prominence over anything no matter what the cost, then an alternative bid strategy should be utilised which prioritises prominence, over user action and cost efficiency.

4. Lack of Search Ad Content & Variations

Ads are one of the most important aspects of any Google Ads campaign, as they are the single element which entice a user to click through and take action on your website.

It’s recommended that a single ad group for search text ads should have 2 to 3 ads, and that Responsive Search Ads are utilised. This is so that Google has a number of variable assets to deploy, gauging which of those assets perform best and then prioritising the better performers to show more over time.

However, we often find that ad groups only have a single ad and moreover, accounts which have existed for some time have not adopted the change from standard text ads to responsive search ads. This in turn, leads to excessive click costs, lower CTRs and generally a far less positive outcome than those more sophisticated accounts, utilising the latest ad formats.

5. Inadequate Budgets

It’s important that your budget matches your account’s potential. In essence, if your ads stop showing at a certain time of day due to lack of budget, then you should pull back some activity or increase your spend.

For example, we have appraised consumer e-commerce accounts before and found that ads stop showing before the evening. This means that ads stopped showing at the time of day that users are most likely to convert; therefore, gaining efficiency and sustainability was almost impossible.

In one instance, the prospect didn’t want to spend more, so we combed through the account and recommended pausing ineffective keywords, as well as non-core products, ad groups and campaigns. We also recommended allocating the budgets differently to the remaining campaigns. The result was that they then began to show at all times of day for their core offering, with a view to expand back out into peripheral product areas, once we’d taken some learning from the newly optimised campaigns and the client had more confidence to spend more.

Shared portfolio budgets can also be problematic. If you have several campaigns and some are more aggressive or yield larger search volumes than others, then the chances are these campaigns will spend all the shared budget, leaving little left for the other campaigns to gain traction.

6. Lack of Conversion Tracking

We often find that accounts are not tracking conversions effectively, or in some cases tracking inferior user actions as a success.

Conversion tracking must align with your campaign goals, so if you’re running a campaign with ‘maximise conversion value’, then Google expects to be able to track conversions which assign a value to each action. For example, if someone checks out on your e-commerce website with an order value of £150, then provisions must be put in place to pull that revenue data through into Google Ads. Failure to do so, means the bid strategy will not optimise over time and impression share will be limited.

Instances where unrelated conversion actions are assigned to campaigns can be equally as problematic. Quite often we see “website visits” set up as a conversion. Google then sees a single visit as a success and will strive for more of those user types, even if the user bounced off the site or didn’t perform a genuinely favourable action. For this reason, it’s important to assign conversions/goals to campaigns, only if they are deemed a genuine success when the action is performed. So, phone calls, contact submissions and live chats would be favourable for a lead gen business (not exclusively) and revenue generating actions for e-commerce businesses (which could include enquiries in some cases).

7. Missing Ad Extensions

Ad extensions are additional assets applied to ads such as links, phone numbers, images, product pricing and additional text information. They not only give the user more information and therefore more chance of favourable action but also, they increase the footprint of the ad, pushing competitors further down and increasing overall prominence.

This additional information gives Google a better understanding of what you are offering. In turn, this leads to better ad relevancy and therefore lower CPCs and better ad positions.

We always find that accounts which do not utilise these extensions effectively (or at all) demonstrate a lack of efficiency, a lower impression share, and generally convert far less.

8. Not Utilising Geo-Targeting & Regional Trends

Different locations yield different opportunities. This might be because a business operates within a radius of their business location, or there’s more demand for products or services in certain regions. Even if demand across the country remains at a similar level, some locations have a denser population, or more affluent residents – therefore justifying bigger budgets and/or more aggression within a geographical area.

Even if you’re targeting the whole of the UK, having control of specific areas can be extremely beneficial. Therefore, it’s recommended to segment locations, especially for those regions which have a higher level of perceived return or potential.

One of our construction e-commerce clients covers the UK, however within the campaigns covering the UK, we have also added regions such as London, Cornwall, Wales and Scotland, to name a few. The benefit here is that we can optimise for these locations independently within the same campaign.

For example, we can increase bid adjustments for London, where the population is dense and there is a concentration of large building sites and small developments. Moreover, logistically the client can cover this area with ease and create efficiency from multiple deliveries in a single day.

On the other hand, the client can deliver to Scotland, Cornwall & Wales, but there is less demand in these areas, building sites are smaller, and logistics are often more costly because a single delivery might take a full day to complete. Therefore, there is far less revenue and repeat business potential in these areas. This means a decreased bid adjustment is logical, so the client pays less for each click, for a lower volume of users in sparse and logistically more costly locations.

By not adding peripheral geographical locations in addition to your core target area, you miss out on gathering data and controlling locations independently. You can also exclude certain regions within the UK (or your target area) which are proven to under-perform, therefore allowing you to allocate more budget to locations that do offer a profitable return.


Running an effective and sustainable Google Ads account can take a lot of time to come to fruition. If you consider these fundamentals at the strategy and build stage, you can avoid common mistakes which lead to inferior performance. Moreover, the time it will take you to start to generate cost-effective leads and/or transactions will be reduced significantly.

How much does a good website cost to build?

  • A brochure site (a place to share information about your products or services) will cost between £6,000-£12,000 depending on the volume of pages, functional elements and any bespoke design requests you may have.
  • An ecommerce website (a place where you can sell your products or services and visitors can complete their transaction online) will cost from £10,000.
  • If you’re looking for completely bespoke design or just a website refresh, we’ll be happy to chat with you and provide a quote for your requirements.

We’ve developed over 200 websites. You can look at our catalogue of work here and chat with our clients if you’d like to get a feel for what it’s like to work with our team before we become partners in your project.

When you work with us, you’ll get that perfect combination of great design and technical development from our whole team, not just one person.

How long does it take to build a website?

Before we start any work, we’ll share a project plan which will include deadlines for providing content, and we’ll keep you updated if the expected times change.

Writing keyword-rich copy will keep visitors on your website and encourage them to work with you. If writing isn’t for you or you just don’t have time, we can produce a content plan on your behalf.

Why you need a website

Most customers will expect you to have a website and may question your legitimacy as a business if they can’t find you online. When a potential customer does find you, what should their first impression be? You want them to be confident when buying from you and to have a good feeling about your brand.

If growing your business is a goal, then having a website is a great place to gain leads. Using the right mix of keywords and a thorough digital marketing plan, you can become good friends with Google! Google will play a significant role in helping your customers find you online and giving you a positive return on investment for the cost of your website and online strategy.

Even the most basic of websites should serve as an informative tool to answer frequently asked customer questions and offer your first port of call for customer service. Your opening times, address and latest news or offers should be easy to find. Ultimately, the better your website is, the easier it will be to find, and a great website will help you to reach more customers.

Being online helps you to reach a much bigger pool of customers than a bricks and mortar store. Your website can be the key to extended success, with no limits on the scope of your customer geography other than your product/service capabilities.

Working with an agency like Browndog will give you a technically sound, fresh and functional website which is responsively designed, and provides consistent brand messaging for your customers. We’ll also take the guess work out of your online strategy and make sure your website is targeting the right customer segments to increase sales opportunities and raise brand awareness.

How much does it cost?

  • A marketing campaign animation or company/product introduction between 90-120 seconds in length will cost between £2,500 and £3,000. This will depend on the length of the video, the content, and any additional options such as a voice over or music. Don’t worry, we can guide you through best practice and find a plan that fits for you.
  • If you’d like us to produce a logo ident or gif animations for you to use on social media and in smaller campaigns, you can expect to pay between £250-£300. This will be a much smaller brief and will take less time than a campaign animation.
  • We’re more than happy to put together a bespoke package for you to include multiple campaign videos, logo idents, voice overs and photography or videography as needed. We do it all!

You can look at our catalogue of work here and chat with our clients if you’d like to get a feel for what it’s like to work with our team before we become partners in your project. 

How long does it take to produce an animation?

But here’s the kind of time you can expect your animation to take:

  • Marketing campaign animations – this will usually take us about three weeks to prepare. We like to allow a week for content and styling, followed by storyboarding and revisions. Finally, we’ll take another week to animate your work. These things are a work of art, you can’t rush them (and we won’t).
  • Logo idents, gifs and short animations – we estimate that this will take up to two weeks.

What kind of animations can we help with?

Ideally, your marketing strategy will include a range of media content to achieve the greatest engagement and response from your audience.

We can help with animations and videos that include company and product introductions, as well as content for specific marketing campaigns. These types of animations can showcase who you are, and what you have to offer. Plus, they are an exciting way to launch a new product or service and get your customers on board.

When you work with us on your branding, why not include a logo ident to add that extra bit of personality to your business and content, setting you apart from your competitors.

Another growing area for animated content is social media and your website. We produce gifs, short video clips and motion graphics for use on web pages and in social posts. This is a great way to captivate the viewers’ attention, share your brand values and advertise your latest campaign or event.

Finally, when you work with us on your website, we highly recommend adding a range of graphics, animations and videos to keep visitors on your site and share your messaging in captivating ways. We’ve provided many website banners and short looping animations for our clients.

We will guide you through each of your animation journey, from assessing the content that will work best for you, to how long your animated content should be and where it should be placed.

Why is animation an important element of your content strategy?

Not only is it effective but using animation can be a cost-saving way to grab the attention of your audience and keep them looking at your content for longer. It’s considerably cheaper than producing recorded video footage because it can be easily edited and updated when needed.

Animation is the fastest growing type of content created by marketers for use on websites and social media, so if you’re not doing it yet, now is the time to start…

We understand that sometimes it can be difficult to explain complex ideas, products or services in text form or with images. That’s why many of our clients work with us to produce animations that take the information off the page and jump out at the audience.

Most importantly, animation has been proven to boost conversion rates on your website. Users are significantly more engaged and more likely to spend longer on your site or complete an action, such as filling in a contact form.

How will animation help my marketing strategy?

Animation is a powerful marketing tool and a great way to show some personality in your brand, making you more memorable (think: the Aldi carrot or the Netflix Tudum).

One of the great benefits of animation is that it can help you to share a lot of information in just a few seconds, because sometimes that’s all the time you have to attract a user’s attention.
