How to write comparison and alternatives pages that buyers trust

Comparison and alternatives pages target some of the most commercial queries a software company can rank for. They also have a reputation problem. Most buyers have read a "vs" page where the author's product wins on every row, and they arrive at the next one expecting the same. G2's 2025 survey of 1,169 B2B software decision-makers found that nearly two in three now prefer to engage with vendor salespeople only in the later stages of their buying journey,¹ so a comparison page may be doing much of the comparing before anyone talks to sales. G2 runs a software review marketplace, so it has an interest in that finding. The page has to earn trust from a reader who starts out sceptical and who will open the competitor's site in another tab to check what you say.

The SaaS SEO guide explains where these pages sit among the other page types a software site needs. The detail here is about building them: which comparisons to write, a structure that survives the reader's check, how to keep competitor facts current, and the guidance and rules that apply.

Start with the competitors that come up in sales calls and lost deals, not the ones with the biggest search volume. If your sales team keeps hearing about one particular rival, buyers are comparing you with it, whether or not a keyword tool shows much demand. Lost-deal reasons in the CRM and notes from demo calls tell you which criteria those buyers use, and those criteria become the rows of your comparison.

The "alternatives to you" page is the one most companies skip. If you do not publish it, a review site or a competitor will, and they will frame it. I would write it, say plainly which needs your product does not meet, and point those readers to the kind of tool that does.

A table where your product wins every row is the fastest way to lose the reader. Every product has trade-offs, and a buyer who has spent ten minutes on the competitor's site knows at least one of them. Name it before they do.

Comparison content counts as review content in Google Search. The reviews system evaluates articles, blog posts and pages written to give a recommendation, an opinion or analysis, and reviews can be about a single item or take the form of comparisons and ranked lists.³ The system works mostly at page level, though a site with a substantial amount of review content may be evaluated as a whole.³ A SaaS company with dozens of "vs" pages should assume the second case could apply to it.

Google's guidance on writing high quality reviews reads almost like a brief for a good comparison page. Its advice is to:

• provide evidence of their own experience, such as visuals or other material from use;⁴
• share quantitative measurements of how something performs in different categories;⁴
• explain what sets something apart from its competitors;⁴
• cover comparable things to consider, or explain which might be best for certain uses;⁴
• discuss benefits and drawbacks, based on original research.⁴

For software, evidence of use means screenshots of both products doing the same task, setup steps you followed yourself, and measurements such as how long an import took or how many clicks a common workflow needs. The helpful content guidance asks a related question: whether the content shows first-hand expertise, for example from having used a product or service.⁵ A page assembled from two marketing sites cannot show that, and readers notice the absence as quickly as any system would.

The guidance also bears on scale. Twenty alternatives pages built from one template, with the competitor's name swapped in and the same paragraph of praise for your own product, match the patterns listed under scaled content abuse in Google's spam policies, which include generating many pages without adding value for users.⁶ Write fewer comparisons and make each one specific.

Comparison pages decay faster than almost anything else on a SaaS site, because the facts belong to someone else and change without notice. A competitor launches a free tier, retires a plan or adds the integration you said they lacked, and your page is now wrong in a way their sales team will happily point out.

I would keep a simple register, in a spreadsheet the content and product marketing teams both use, with one row per factual claim about another product.

Update the visible date only when the page has changed. Show a clearly labelled date, such as "Last updated", and keep it consistent with the dates in structured data.⁷ Changing the date of pages to make them seem fresh when the content has not substantially changed is one of the warning signs in the helpful content guidance.⁵ A monthly check that finds nothing new is recorded in the register. It does not justify a new date on the page.

Comparison pages tempt people into star ratings: a 4.8 for your product, a 3.9 for theirs. If those numbers are not drawn from genuine reviews, leave them out. The CAP Code says marketing communications must not contain fake consumer reviews, meaning reviews that claim to be based on a person's genuine experience and are not.⁸ Since April 2025, UK consumer law has also banned fake reviews and false or misleading consumer review information, which the CMA's guidance says covers overall ratings, review summaries, review counts and rankings.⁹ In the US, the Federal Trade Commission's rule on reviews and testimonials covers fake reviews, including AI-generated ones, and prohibits a business from misrepresenting that a website it controls gives independent reviews of a category that includes its own products.¹⁰ That last point matters for any "best [category] software" roundup published on your own site.

Structured data has its own rules. Where the entity being reviewed controls the reviews about itself, pages using LocalBusiness or other Organization markup are ineligible for star review features in Google.¹¹ Software apps are among the types that can show review snippets.¹¹ On a comparison page, I would not mark up ratings for either product. You control the page, the ratings would be about a competitor you are trying to beat, and nothing about that is a review a searcher would trust. If you quote third-party review scores in the copy, name the platform, link to it and date the figure.

Comparative advertising is regulated, and the rules differ by country. In the UK, the CAP Code has a section on comparisons with identifiable competitors. It requires them to compare products meeting the same needs or intended for the same purpose,⁸ and to objectively compare one or more material, relevant, verifiable and representative features, which may include price.⁸ They must not create confusion between the marketer and a competitor or their trade marks,⁸ must not discredit or denigrate a competitor or its products,⁸ and must not take unfair advantage of the reputation of a competitor's trade mark.⁸ The code also requires marketers to hold documentary evidence for claims consumers are likely to regard as objective.⁸ Separately, the Business Protection from Misleading Marketing Regulations 2008 include a regulation on comparative advertising.¹²

In practice, the rules and good copywriting push in the same direction. Specific, checkable statements about features and pricing are easier to defend and more persuasive than adjectives. "Their entry plan includes three users; ours includes five" is a claim you can evidence. "Their support is terrible" is denigration, and it tells the reader nothing they can use.

• Any page with a factual claim about a competitor that nobody can source. Remove or correct it before anything else.
• Tables that show a clean sweep for your product. Add the rows where the competitor is stronger.
• Pages with no visible date, or a date that changes on every deploy.
• Ratings in the copy or markup that do not come from genuine, attributable reviews.
• Templated alternatives pages that differ only by the competitor's name. Merge them or rewrite the ones that buyers search for.
• Calls to action that ignore where the reader is. Someone comparing two tools usually wants a trial, a migration guide or a pricing page more than a sales call.
