Comparisons and buying guides that help customers choose

A good comparison or buying guide picks the criteria customers really decide on, sets the options side by side with checked facts and says for each option who it does and doesn’t suit. A comparison also names drawbacks, explains every recommendation and is honest about your own offer. Google recommends this approach in its guidance on reviews and comparisons.

Why do comparisons matter?

Customers who are close to a decision ask comparative questions: “Is a heat pump or a hybrid boiler better for a 1930s house?” or “Which e-bike suits a twenty-kilometre commute?”. Questions like these go to AI assistants as well. Google writes that AI Mode is especially helpful for queries that need further exploration, reasoning or complex comparisons.

For a question like that, an assistant can retrieve sources that have already weighed up the options. A page with clear criteria, a table and a well-reasoned recommendation gives it usable material. The same page helps the customer who lands on your site directly.

Google assesses comparisons, rankings and recommendations with a dedicated reviews system. That system looks at content you publish yourself to recommend or analyse something, and according to Google it currently applies to eleven languages, English and Dutch among them. It rewards in-depth research over thin summaries of a list of products.

How do you choose the decision question and the criteria?

Step 1: pick the decision question

Start with a question customers really ask. Good sources are customer contact, quote requests and search queries in Google Search Console. How to collect those questions is covered in Researching customer questions and keywords. Familiar forms:

• “X or Y?” (Shopify or WooCommerce, laminate or vinyl);
• “Which one suits my situation?” (which mattress for back pain);
• “What’s the difference between ...?” (mid-drive and front hub motors);
• “What do I need for ...?” (which drill for concrete).

Choose one decision question per page. A page that tries to settle three decisions at once turns into a list. The search intent behind a comparative question is almost always: help me choose.

Step 2: set the criteria

Ask yourself what a customer ultimately decides on. Google recommends focusing on the most important decision-making factors, based on your experience or expertise. For a car review, that might be fuel economy and safety; for an e-bike, range, weight and maintenance.

Don’t pick too many. Five to eight criteria that really matter are more useful than twenty rows, half of which make no difference. Explain briefly why each criterion counts.

How do you gather the facts and put them in a table?

Step 3: gather and check the facts

A comparison stands or falls on the accuracy of its facts. Use:

• the manufacturer’s specifications, with a link;
• your own measurements or tests, with an explanation of how you carried them out;
• official sources for rules, subsidies or standards;
• your own practical experience, clearly presented as experience.

Note for each fact where it came from and when you checked it. For reviews, Google recommends providing evidence of first-hand experience, such as photos, and showing quantitative measurements where possible. More on making experience visible in E-E-A-T: how do you show experience and expertise?

Step 4: put the options in a table

A table shows at a glance how options compare. Keep it simple: options in the columns, criteria in the rows, and a short value in each cell.

Say a bike shop compares two motor types for e-bikes.

Put the table in the page’s HTML, not as an image. A reader using a screen reader can’t use an image of a table, and search engines and AI assistants find its contents harder to read.

How do you write advice that helps people choose?

Step 5: write who it suits and who it doesn’t

A table shows differences; a recommendation translates them into situations. Write two short lists for each option:

• A good fit if you cycle more than fifteen kilometres a day and live in a hilly area.
• A less good fit if you mostly make short trips on flat ground and want a simple bike.

Google recommends discussing what works best for which use. When you call one option “the best”, Google also asks you to explain why, with evidence from your own experience.

Step 6: name the drawbacks

A comparison without drawbacks reads like an advert. Google lists discussing pros and cons, based on your own research, as a mark of a good review. Every option has limitations; write them down, including for the products you sell yourself.

How do you compare your own offer fairly?

Step 7: place your own offer honestly

If you compare your own product with other options, there is a conflict of interest. The quality rater guidelines treat “reviews” by the manufacturer itself as less trustworthy than experiences from real users. That needn’t be a problem, as long as you are open about it:

• say clearly which options you sell yourself;
• use the same criteria for your own product as for the rest;
• name situations in which another product is a better fit;
• don’t make negative claims about other providers that you can’t back up with a source.

For reviews, Google also recommends including links to other useful resources, including ones on other sites, so the reader can keep comparing.

How do you keep a comparison current?

Step 8: schedule a fixed review moment

Models, prices and terms change. Show a visible date on the page and schedule a fixed review moment. Only change the date when you have really gone through the content. An outdated comparison may be picked up by an AI assistant, with your name attached to it.

Is your comparison right?

Go through these points before you publish a comparison, and again at every review moment.

How Outseen approaches this

At Outseen, a writer creates comparisons and buying guides from your briefing and sources, a reviewer checks the facts and text, and you give feedback before publication. How to apply this to an online shop is covered in GEO for online shops and optimising product pages. General writing rules are in writing content AI can cite. At Outseen, answering customer questions on your site falls under AEO.

What does this mean for your business?

Look at the decision question you get most often, in the shop, on the phone or in quote requests. You probably answer it again in every conversation. Write that conversation out once as a comparison, using the criteria you mention when you talk to customers, and you have a page customers can read before they get in touch.

Be honest about what you sell yourself and about the drawbacks. A comparison that only praises your own product does not help the reader, and gives an AI assistant little reason to use it as a source.
