Competitive analysis in marketing: message, channels, share of voice

Marketing competitive analysis is a message problem, not a feature table. The useful output is three things: what each competitor claims and who they are claiming it to, which channels they are spending real money on, and what share of the category conversation each one holds. All three can be assembled from public evidence in a day, using ad transparency libraries, job postings, pricing pages, review sites, company filings and the words on their own homepage. The deliverable is one page your sales team carries into calls, not a forty tab spreadsheet nobody opens twice.

Feature comparisons are a product exercise. Marketing needs to know which story is winning, where it is being told, and which claim you can take from them.

Pick five competitors, in three categories

• Two direct competitors that come up in your own deals most often. Ask sales, not search volume.
• Two substitutes that solve the same problem differently, including the spreadsheet, the agency or the internal team people use instead of buying anything.
• One insurgent that is newer, cheaper or louder than you. They will tell you what the next eighteen months of messaging looks like.

Five is the limit. Analysts who track twenty competitors produce documents and no decisions.

The message teardown

For each competitor, copy the exact words from four places and put them side by side: the homepage headline, the first sentence under it, the pricing page, and the top of their main product or service page. Then answer five questions in their words, not yours.

Question	Where the evidence is
Who do they say this is for?	Homepage headline, nav labels, case study titles, the industries named in the footer
What is the promise?	The first sentence under the headline, and the claim repeated in every ad
What are they positioning against?	Comparison pages, the phrases "unlike", "without" and "instead of"
What proof do they offer?	Named customers, numbers, certifications, review scores, analyst mentions
What are they not saying?	The absent subject is often the weakness: no pricing page, no security page, no integrations list

Write each competitor's positioning as a single sentence in the format: for this buyer, we do this thing, unlike that alternative. If you cannot write it from their site, their positioning is unclear, which is itself an opening.

Find out where they actually spend

Spending leaves public traces. Five sources cover most of it.

• Ad transparency libraries. Google's Ads Transparency Center shows ads an advertiser is running, and the major social platforms publish their own ad libraries. Read the creative, not just the count: repeated creative that stays live for months is creative that is working.
• Job postings. A listing for three paid media managers tells you where next year's budget is going. A listing for a technical writer tells you documentation is becoming a channel.
• Their own site structure. A large resource library means content investment. A heavy events page means field marketing. A partner directory means channel sales.
• Email and nurture. Sign up with a real address you control and keep a folder. Their sequence is their funnel, written down for you.
• Filings and public records. In the UK, accounts and officers are free to read on the Companies House register, which gives you employee counts and scale. Public companies disclose far more in their reports and calls.

Share of voice, measured simply

Share of voice is the proportion of the category conversation each competitor holds. You do not need a platform to get a usable reading.

1. List twenty queries that define your category, split between problem queries and solution queries.
2. For each, record which competitors appear in the first ten organic results, and who holds the map results if location matters.
3. Count appearances per competitor and divide by the total. That is your organic share of voice, and it is a number you can repeat every quarter.
4. Do the same for the review platforms your buyers use: count reviews, average rating, and recency.
5. Add branded search demand as a proxy for brand strength, using a keyword tool to compare brand name volumes.

Record the date and the method in the file. The absolute numbers matter far less than the direction of travel between two quarters.

Talk to people, which is the part everybody skips

• Win and loss interviews. Ten short calls with recent wins and losses beat any desk research. Ask who else they looked at, what nearly stopped them, and what phrase from the competitor stuck with them.
• Your own sales team. Ask for the objection they hear most and the competitor claim they find hardest to answer. That is your next piece of content.
• Review mining. Read the three star reviews of each competitor, not the one star ones. Three star reviews come from people who tried properly and were disappointed for a specific reason.
• Churned customers, theirs and yours. One conversation with somebody who left a competitor is worth a month of monitoring.

The one page output

Everything above compresses into a single page per competitor, in this shape:

COMPETITOR: name
Positioning (their words): for [buyer], we [promise], unlike [alternative]
Primary buyer: ...
Proof they lead with: ...
Channels with real spend: ...
Price position: ...
Share of voice (date, method): ...
Where they beat us: ...
Where we beat them: ...
The claim we can take from them: ...
What to say when a prospect mentions them: two sentences

That last line is why the document gets used. Give sales two sentences they can say out loud, and the analysis stops being a marketing artefact.

Keeping it alive without it becoming a job

• A quarterly refresh of share of voice and the message teardown, dated, in the same file.
• Alerts on each competitor's brand name, plus a monthly check of their pricing page and changelog.
• A standing five minute slot in the monthly marketing meeting: what changed, and does anything we are doing change because of it.
• One rule: every refresh ends with a decision or it is cancelled.

This page covers the marketing view of competitive analysis: message, channels and share of voice. For the product and feature level comparison, and for a full competitor keyword gap analysis, each deserves its own treatment.

Where people get stuck on competitive analysis in marketing

How often should competitive analysis be refreshed?

A quarterly refresh of the one pagers, with the share of voice numbers re measured the same way each time. Anything more frequent becomes monitoring, which is a different and much smaller job best handled by alerts.

How many competitors should we track?

Five, chosen as two direct, two substitutes and one insurgent. The limit forces you to pick the ones that show up in real deals rather than the ones that show up in search tools.

What if a competitor is much bigger than us?

Study what they cannot do because of their size: segments too small for them, service levels they cannot staff, decisions they cannot make quickly. Large competitors leave specific, nameable gaps, and your positioning sentence should sit inside one of them.

Is a SWOT analysis useful here?

It is useful as a summary after the evidence is gathered, and useless as the starting point, because a SWOT written from opinion is just a list of beliefs. Gather the public evidence first, then let the four boxes write themselves.

What is the single most valuable input?

Ten win and loss interviews. They tell you which competitor claims actually move a decision, which is the only ranking of competitors that matters commercially.

Share of voice among the answers

Share of voice has always been a count of mentions against rivals, whether in press, search or social, and a rival with a louder voice usually looked like a rival with a larger share. Counting it inside assistant replies is the same arithmetic on a new set: ask twenty category questions and count how often each competitor is named, yourself included. The one page output the sales team uses could carry that single number. AI Knows Us does the count and records the sources.
