Analyzing competition in marketing: the public evidence sources and what each one reveals

Analysing competition in marketing is a matter of reading public evidence correctly, and almost everything you need is already published. Their website tells you their positioning and their priorities, ad transparency libraries show the creative and claims they are paying to put in front of buyers, job adverts reveal the capabilities they are building next, review platforms give you their customers' own words about what works and what does not, and pricing pages, financial filings and trade press fill in the commercial picture. The discipline is not collecting more, it is reading each source for the one thing it genuinely shows and then stopping. A competitor file that ends without changing a decision was research, not analysis, so plan for two or three decisions before you open the first tab.

This page covers the evidence sources and how to read them. For the message, channel and share of voice framing, see a page on competitive analysis in marketing.

Pick the right three competitors first

Most competitor files are too wide to be useful. Choose three, each for a different reason: the one you lose deals to most often, the one growing fastest in your category, and the alternative your buyer considers that is not a direct competitor at all, which might be an in house team, a spreadsheet or doing nothing. The third one teaches you more about your market than the first two, because it is what you are really competing with.

Source by source, and what each reveals

Source	What it reveals	How to read it
Homepage and top navigation	Their chosen positioning and who they are prioritising	Note the first sentence and the order of the navigation. Both are decisions, argued over internally
Pricing and packaging pages	Their segmentation and where they make money	Which features sit in which tier shows what they believe buyers pay for
Ad transparency libraries	Active paid creative, claims and how long each has run	Long running creative is tested creative. New creative is a bet
Job adverts and hiring pages	The capability they are building next	A new lifecycle marketing role means retention problems or plans. Several sales roles in one region means expansion
Review platforms	Their customers' own words on strengths and friction	Read the three star reviews. They are the honest ones
Content and blog cadence	The topics and buyer stages they are investing in	Sort by date. Volume is less telling than which subjects they keep returning to
Search visibility tools	Which queries they earn traffic from, and which they pay for	Look for queries they rank on and you do not, and for paid terms they hold constantly
Email and nurture flows	Their claims under pressure, and their objection handling	Subscribe. The fourth and fifth emails carry the real argument
Trade press, filings and funding news	Scale, direction and constraints	A funding round or a filing tells you what they will spend on next
Conference and event lists	Which audiences they are paying to meet in person	Sponsorship is an expensive, deliberate signal of segment focus
Their own customers	Why they chose, and what they wish were different	Ask in your own sales calls: what else did you look at, and what nearly stopped you choosing us

Reading signal and ignoring noise

Three tests keep a competitor file honest.

• Repetition over time. One blog post is noise, a quarter of posts on the same subject is a strategy. Date everything you collect.
• Money attached. Spending is the clearest signal there is. Paid ads, sponsorships, new hires and a rebuild of a pricing page all cost something and are therefore decisions somebody defended.
• Consistency across sources. A claim that appears in their homepage, their ads, their emails and their job adverts is their actual position. A claim that appears in one place is a test.

Record the date and the source for every item. A file without dates becomes misleading within a quarter, so refresh it every three months and keep the previous version, because the change between the two versions is the most valuable part of the whole exercise.

Turn it into a comparison a buyer would recognise

Build one table with your three competitors as columns and these as rows: who they say they are for, the single claim they lead with, their proof, their price position, their strongest channel, the friction their reviews mention, and the question you would struggle to answer in a head to head. Fill it from evidence only, with a source noted on each cell.

Then write the two sentences that matter. The first: the reason a buyer picks them over us today. The second: the reason a buyer picks us over them, stated in a way the buyer would agree with rather than in words only your marketing team uses. If you cannot write the second sentence from evidence, that is the finding, and it is a positioning task rather than a campaign one.

End in decisions

Close every competitor review with three decisions and an owner for each. Useful ones look like this: the claim we lead with changes to this, we stop competing on this term and win on that one instead, we build the proof asset that their reviews show their customers want, we match this one feature or price point and ignore the rest, or we go after the segment they are visibly leaving.

Keep a one page record of what you decided and why. In six months, when the same debate returns, the record is what stops you redoing the research.

How often should competitive analysis be refreshed?

A full refresh each quarter and a quick monthly pass over the sources that move fastest, which are ads, pricing and job adverts. Anything older than a quarter should be labelled with its date before anyone acts on it.

Which tools are worth paying for?

Start with the free sources, which are the ad transparency libraries, review platforms, job pages, their own emails and your own sales calls. Add a paid search visibility tool once you need query level comparison, since that is the one thing the free sources do not give you.

How many competitors should we track?

Three closely, with a longer list reviewed once or twice a year. Depth on three beats a spreadsheet of twenty that nobody reads.

Is it acceptable to subscribe to a competitor's emails?

Yes. Their marketing is published to anyone who asks for it, and reading it is ordinary market research. Use a work address rather than a disguise, keep to published material, and do not misrepresent who you are to obtain anything.

What should a competitive analysis document contain?

One page per competitor with dated evidence and sources, one comparison table, the two positioning sentences, and three decisions with owners. Anything longer stops being read, which makes it worthless regardless of quality.

The competitor file's missing source

Add one section to your competitor file that none of the usual sources can fill: what an assistant says when a buyer asks which company to use. Ask ChatGPT, Gemini, Perplexity, Claude and Google's AI Overviews in a buyer's words, naming nobody, and note which rivals come back, in what order and for what reasons. It differs from every rival's website, ad library and review profile you already collected, because the assistant weighs them against each other before it answers. AI Knows Us reports which of the five name your business beside a rival, and which sources shaped each answer.
