Digital marketing tools are the software a business uses to measure what happens online, understand what people search for, produce content and distribute it: analytics, keyword research, email, social, CRM, advertising. In May 2025 the census by Scott Brinker and Frans Riemersma counted 15,384 of them, 9% more than the 14,106 of the year before, with 2,489 new entries and 1,211 products gone through acquisition or closure.
No business has to choose from 15,384 products. It has to choose eight or ten, switch them on in the right order and know what they cost each month. This guide does that sum, with list prices read on the official websites on 26 August 2026.
The problem isn't choosing, it's using what you already have
Gartner has measured martech stack utilisation for years, meaning how much of the functionality paid for is actually switched on. In the Marketing Technology Survey 2025 it fell to 49%, and only 15% of organisations count as high performers, those that hit their objectives with a positive return. In the same survey technology accounts for almost 22% of total marketing spend, and a marketing leader looks after nine channels on average.
Gartner's CMO Spend Survey 2025, with 402 marketing leaders interviewed between February and March 2025 in North America, the UK and Europe, puts the marketing budget at 7.7% of revenue. The sample is largely made up of companies with more than a billion dollars in revenue, so the absolute values don't transfer to a UK SME. The proportions do.
Applied to a business with a turnover of £5 million, those proportions give roughly £385,000 of marketing budget and £85,000 of technology, half of it spent on features nobody opens. That is the sum to do before adding the eleventh subscription, not after.
What businesses actually have in place
Most articles on this subject start from a company that already has everything and just needs to pick the best tool. The real picture is different. In the UK, the ONS Business Insights and Conditions Survey tracks adoption of AI among businesses with 10 or more employees: around 12% used at least one AI technology in September 2023, around 35% in June 2026, and among large businesses (250 or more employees) the figure is 49%. Only 10% of the businesses using AI describe their use as extensive.
The more basic tools are a different story. In Italy, where most of our clients are, the national statistics office Istat found in its 2025 ICT survey that only 21.1% of SMEs with 10 to 249 employees use a CRM, against 56.5% of large companies: four SMEs out of five don't have one. That is why the minimum stack for an SME is built in a different order. Talking about stack orchestration with a business that keeps its sales contacts in a spreadsheet is wasted time, and it happens more often than industry blogs let on. On how AI fits into day-to-day work we have written a dedicated guide to AI in digital marketing.
The five layers, in the order to switch them on
The order matters more than the choice. A keyword research tool bought before measurement is installed produces lists of words that nobody will be able to verify.
Layer 1. Measure, at zero cost
Google Analytics 4, Google Search Console, Google Tag Manager and Looker Studio cost nothing and cover almost every question a business asks about its own website. GA4 tells you what happens inside the site, Search Console what happens before the user gets there. They are two different tools answering different questions, and confusing them is why many internal reports don't add up: we explain it in detail in the guide to Google Analytics.
The fifth piece is Microsoft Clarity, which records sessions and heatmaps. Microsoft's documentation describes it as free forever, with no traffic limits, with a cap of 100,000 recorded sessions per day per project and thirty days' retention of recordings. No B2B website comes near that cap.
Layer 2. Understand what people search for
This is where the real costs start. The two suites that cover keyword research, competitor analysis and rank tracking are Semrush and Ahrefs. Both have a large UK database; the differences lie in the backlink index, the limits of each plan and the interface.
Add to these Screaming Frog SEO Spider, the crawler used to go through the pages of a site. The free version stops at 500 URLs, which is enough for most company websites. The method for using this data, not just the price list, is in the guide to keyword research and in the comparison of keyword research tools. Before that, it is worth being clear about search intent: high volume on the wrong query is traffic that turns into nothing.
Layer 3. Produce and publish
Canva for graphics and Metricool for social scheduling and analytics. Metricool is Spanish, has a free plan that handles one brand and twenty scheduled posts a month, and the paid version starts at $20 a month. In the UK Canva Pro costs £100 a year for one person, and Canva Business £180 a year per person.
This is the layer where money is spent worst, because it is where tools look most alike and the choice ends up depending on who gave the most convincing demo.
Layer 4. Write to people who have already left their address
Brevo is the most sensible email platform to start with in Europe: the free plan sends 300 emails a day, stores up to 100,000 contacts and allows 2,000 unique contacts in active automations, with a single user. Mailchimp's free plan, by comparison, stops at 250 contacts and 500 sends a month, with a daily limit of 250. The gap between the two free plans is an order of magnitude, and it is easy to miss when you only compare the headline prices.
Layer 5. Keep watch on generated answers
This category was born in the last two years: tools that check whether and how a brand is cited inside ChatGPT, Perplexity, Gemini and Google's AI Overviews. Ahrefs sells Brand Radar AI from $199 a month; Semrush includes AI visibility monitoring in plans from the second tier upwards, with 50 prompts on the Starter plan and 200 on Advanced. The full landscape is in the roundup of the best AI visibility tools, and the strategic picture in the guide to generative engine optimisation.
One figure that argues for caution: in Gartner's October 2025 survey of 413 martech leaders, 81% are already experimenting with AI agents, but 45% say the features offered by vendors don't live up to the sales promises, and 50% don't have the technical stack and data ready to use them.
What the stack costs, price list in hand
Here is the table. Prices read on the official websites on 26 August 2026 and shown in the currency the vendor publishes them in: converting them at the day's exchange rate would give a number that is wrong tomorrow.
| Tool | What it's for | Free plan | First paid plan |
|---|---|---|---|
| Google Analytics 4 | Behaviour on the site | Yes, complete | – |
| Google Search Console | Organic search data | Yes, complete | – |
| Looker Studio | Reports and dashboards | Yes, complete | – |
| Microsoft Clarity | Recordings and heatmaps | Yes, no traffic limits | – |
| Screaming Frog SEO Spider | Site crawling | Up to 500 URLs | £199/year |
| Semrush | SEO, competitors, AI visibility | Yes, very limited | $139/month (SEO, 5 sites, 500 keywords) |
| Ahrefs | Backlinks and keyword research | Yes, limited | $29/month (Starter) |
| Brevo | Email and automation | 300 emails a day | Tiered by volume |
| Mailchimp | 250 contacts, 500 sends/month | Tiered by contacts | |
| Canva | Graphics | Yes | £100/year (Pro, one person) |
| Metricool | Social scheduling and analytics | 1 brand, 20 posts a month | $20/month (Starter) |
Three realistic setups come out of this.
- The zero-pound stack. GA4, Search Console, Tag Manager, Looker Studio, Clarity, Screaming Frog up to 500 URLs, free Brevo, free Canva, free Metricool. It covers a company website under five hundred pages and an email list under 300 sends a day. Cost: zero.
- The small business stack. Add Semrush SEO at $139 a month and Metricool Starter at $20, plus Canva Pro at £100 a year (£8.33 a month). Total $159 a month plus £100 a year, and another £199 a year if the site goes over 500 URLs and needs the Screaming Frog licence.
- The agency or multi-site stack. Semrush Pro+ at $299 a month (15 sites, 1,500 keywords) and Ahrefs Standard at $249. That is already $548 a month, and the sum has to be redone on the number of clients managed, not on features.
The first tool to open is free, and here are the numbers
Between 26 May and 23 August 2026, on the Italian market, the visilay.com domain recorded 14,312 impressions and 49 clicks in Search Console: a CTR of 0.34%, average position 46.3. This is our own data, not a client's, and it shows something no paid suite puts on its front page.
In the same period a single page, our SEO services page, collected 8,383 impressions and 4 clicks, with an average position of 19.1. A rank tracker would have flagged that page as ranking for dozens of keywords, and it would have been right. Search Console says that appearing 8,383 times persuaded four people to click. The worst query is agenzia lead generation (lead generation agency): 874 impressions, zero clicks, average position 73.2.
The two tools don't contradict each other, they answer different questions. The rank tracker tells you where you are, Search Console tells you what happens when you are there. The second costs nothing and should be checked first, because without that number you end up optimising pages nobody would click anyway. The list of metrics to keep an eye on is in the guide to SEO KPIs, and the method for turning them into financial value in the piece on SEO ROI.
The counter-example, with numbers, is the Macropix case we described in the article on SEO for manufacturing: the keyword monitor pubblicitario (advertising display) moved from position 88 to position 2, with a share of voice of 25.55% on the ledwall cluster, ahead of Amazon at 18.08%. There the tool measured a result that had already been produced by something else. More numbers like these are on the projects page.
Three mistakes that double what you spend
Buying the biggest suite straight away. Semrush Advanced costs $549 a month and tracks 5,000 keywords. A business monitoring forty is paying for 4,960 positions it will never look at. You move up a plan later, when the limits genuinely get in the way.
Paying twice for the same feature. Semrush and Ahrefs largely do the same things on different databases. Having both only makes sense if one covers a market the other knows poorly, as happens with some non-English markets: in Italy, for example, many agencies pair the local tool SEOZoom with one of the two international suites. Having three almost never makes sense.
Buying before measurement is installed. Without Search Console and GA4 set up there is no way of knowing whether the paid tool is changing anything. This is the mechanism that pulls stack utilisation down to 49%: nobody cancels a subscription they can't prove is useless.
How to choose without trying them all
Four criteria, in order of weight.
- Database coverage for your market. This applies to everything search-related. A suite with ten million UK keywords and one with two million give different answers on the same query, and neither says so on its home page.
- Data export. If a tool doesn't export to CSV or has no API, you lose the history the day you switch. This matters most for rank trackers, where the history is the useful part.
- Number of people who will need to open it. Many price lists are per user. Canva Business at £180 a year becomes £900 with five people.
- What happens when you cancel. Some platforms keep your data for a grace period, others close access the same day.
Everything else, including the AI features every vendor has added in the last eighteen months, is assessed on a trial. On how to split the work between organic search and paid campaigns, which is the other half of the budget decision, we have written in SEO and Google Ads.
Frequently asked questions
Between six and ten. Five are free and cover measurement (Google Analytics 4, Search Console, Tag Manager, Looker Studio, Microsoft Clarity). The others depend on the channels in use: an SEO suite, an email platform, a social tool, a CRM. According to Gartner's Marketing Technology Survey 2025, companies use on average 49% of the features they pay for, so the more concrete risk is buying too much, not too little.
It depends on what you need most. Semrush starts at $139 a month with 5 sites and 500 tracked keywords, and includes AI visibility monitoring from the Starter plan. Ahrefs has a Starter plan at $29 a month and is the stronger of the two on backlinks. For a business working only in the UK, one of the two plus Google's free tools covers most needs; paying for both rarely makes sense.
For a site under 500 pages and an email list under 300 sends a day, yes. Google Analytics 4, Search Console, Tag Manager, Looker Studio and Microsoft Clarity are complete and have no traffic limits, Screaming Frog covers 500 URLs for free, and Brevo's free plan sends 300 emails a day with up to 100,000 stored contacts. What is missing is competitor data and estimated search volumes.
Zero with free tools only. About $159 a month plus £100 a year for a small business (Semrush SEO $139, Metricool Starter $20, Canva Pro £100 a year), plus £199 a year for a Screaming Frog licence if the site goes over 500 URLs. Over $500 a month for an agency managing several clients. List prices checked on 26 August 2026.
You do if a significant share of the queries in your sector already show an AI Overview, or if customers arrive mentioning ChatGPT. Ahrefs sells Brand Radar AI from $199 a month and Semrush includes prompt monitoring from the Starter plan. The caution suggested by Gartner's October 2025 survey of 413 martech leaders applies: 45% say the AI features offered by vendors don't keep their sales promises.
The cost that appears in no price list
A £70-a-month subscription that needs two hours a week to be used properly costs, at an internal cost of £35 an hour, about £280 a month in labour: four times the fee. No comparison table says so, and it explains Gartner's 49% better than any point about the interface. Whoever signs off a renewal should ask how many hours that tool has taken up in the last three months, not how many more features it has than the competition. If the answer is zero hours, the problem isn't the price.
