Appliance buyers often arrive knowing exactly what they want. They have a model number from a review, a comparison table or the plate inside the old machine’s door, and they type it into Google. The same model is often stocked by many retailers, many of them carrying the manufacturer’s description, and it may be replaced by a near-identical successor within a year or two.

So appliance SEO is less about broad category terms and more about being the best result for a specific model, then handling what happens when that model changes. This page applies Google’s documentation to those problems, with links to each source. My own advice is labelled as such.

Model numbers are often the search term

Appliance model codes tend to be long strings of letters and digits, and the same machine in a different colour often has a different code. A fridge freezer in white, silver and black may be three model numbers with three barcodes.

  • Show the full code as visible text near the product name. Do not leave it only in a spec table that loads by script.
  • Give each colour its own identifier. Google’s variant documentation requires a unique sku or gtin for every variant and an ID for the group. Branded appliances usually carry a barcode, so gtin is often easy to supply.
  • Watch letter case. Model codes are usually written in capitals. Google’s URL guidance says to normalise case if your server treats upper and lower case as the same, so that one page does not appear under two addresses.
  • Keep spaces out of the sku. Google’s merchant listing documentation says it must not contain whitespace.

One page per colour, or one for the group?

Google’s variant documentation offers two set-ups. A single page can represent the group, with one canonical URL, and each colour must then be preselectable through its own URL and addable to the basket. Alternatively, each variant can have its own page and canonical, with the full group repeated in every page’s markup.

For appliances I lean towards one page per colour. Buyers often search the exact colour’s model code, and a page with that code in its title and heading is the strongest match. List the colours as variants in a ProductGroup with variesBy set to https://schema.org/color, and link the pages to each other.

Standing out when every shop has the same copy

Many appliance retailers load the manufacturer’s description, feature list and images. When many pages say the same thing, a retailer needs to add something. Google’s documentation in my sources does not address this, so these points are my advice.

  • Fit facts. Exact dimensions with the door open, ventilation gaps, whether the door hinge can be reversed, and whether an integrated model suits a standard housing unit.
  • Installation facts. Hose lengths, whether it needs a dedicated circuit, and what the delivery team will and will not connect.
  • Your own photos and video, such as the machine in a real kitchen or the drum interior. Google’s ecommerce structured data overview recommends VideoObject markup for a product page that features video.
  • Honest answers to the questions your customer service team hears every week.

Successor models and discontinued pages

Manufacturers refresh ranges regularly, and the outgoing model can keep search demand and links long after it stops being sold. Google offers no specific rule here, so this is my approach.

  • While stock remains, keep the page as it is and keep the availability in its Offer accurate.
  • When it is gone for good but people still search for it, keep the page live. State clearly that it has been replaced, and link prominently to the successor and one or two close alternatives.
  • When the old page no longer has value, a permanent redirect is a common choice where the successor is a close equivalent. Google’s canonical documentation treats redirects as a strong signal, though it discusses them for retiring duplicate URLs, not for replacement models.

Google’s advice to noindex or 404 an empty category is about categories, not individual models. Applying it to every discontinued product would throw away pages that still answer searches.

Graded, ex-display and refurbished units

Appliance retailers often sell the same model in more than one condition: new, graded with cosmetic marks, ex-display, or refurbished. Google’s merchant listing documentation gives itemCondition three values: NewCondition, RefurbishedCondition and UsedCondition, with one value per Offer.

  • Choose the value that honestly describes the unit, and describe the grade in plain words on the page.
  • Give graded stock its own page and SKU, linked to the new model’s page, with the model code and the grade in the title.
  • Where single graded units come and go quickly, one graded page per model is easier to maintain than one page per unit. That is my advice.

Remember that the Offer must be a single Offer, not an AggregateOffer, and its price must be greater than zero.

Delivery, installation and recycling

Large appliances bring services with them: two-person delivery, connection, removal of the old machine and extended cover. Google’s merchant listing documentation suggests a delivery policy set once under Organization, with offer-level shippingDetails only for exceptions. A returns policy can likewise be defined once and referenced from each offer by its @id. That suits appliances well: one policy for parcel-sized items such as kettles and microwaves, with overrides for washing machines and range cookers.

Service choices at the basket should not create crawlable URLs. A parameter such as ?install=yes linked from every product page doubles the URLs Google could crawl for no benefit.

Filters by size, capacity and type

Appliance categories filter by width, height, capacity in kilograms or litres, freestanding or integrated, energy class, noise level and colour. Every extra filter multiplies the URLs a crawler could follow, and Google’s faceted navigation guide says that crawling them can cost server resources and delay new pages being found.

  • Build pages for combinations people search, for example slimline 45 cm dishwashers, 9 kg washing machines or integrated fridge freezers. These are examples; check your own query data. This is my advice.
  • Block the rest with robots.txt rules for filter parameters, keeping product pages and one unfiltered listing crawlable, or hold filter state in a fragment.
  • Return a 404 at the URL itself for impossible combinations, such as an integrated range cooker.

Energy labels and product information sheets

Large appliances usually display an energy label, with a product information sheet alongside. A label image carries its meaning as text inside the picture, which search engines may not read reliably. Google’s image guidance calls alt text the most important image metadata, so state the energy class in the alt text and as text near the price. Google also advises against text-heavy images as a page’s preferred image, so keep the label out of the main image slot.

Checks for an appliance site

  1. Search for five of your model codes. Note whether you appear, and which page of yours ranks.
  2. Load a model code URL in upper and lower case. One form should serve the page and the other should redirect to it.
  3. Test a product in the Rich Results Test. Check that gtin and itemCondition are present.
  4. Find three discontinued models with search impressions in Search Console. Check what each page now shows.
  5. Compare a graded unit’s page with the new model’s page. Do the titles, conditions and links make the difference clear?
  6. Select installation at the basket and see whether the URL changes.
  7. Apply width and energy class filters together and check whether the URL can be crawled.
  8. Check the energy label’s alt text on a product page.

When I tested five UK appliance product pages with Lighthouse on 23 October 2026, one product URL returned a 410, the server’s way of saying a page is permanently gone. For a retired model that people still search for, the options above keep more value than a dead URL. Of the four pages that loaded, two had links without descriptive text, one had a link that was not crawlable and one had images without alt text. One passed every check. Lighthouse’s SEO audit stops at basics like these; model codes, shared copy and graded stock are outside it.

Appliance pages also often run a lot of third-party script, covered in appliance website performance. For the commercial side see selling appliances online, and for configurator tools, the appliance configurator page. When ranges change or a site is replatformed, my SEO migration service aims to protect existing rankings, and an ecommerce SEO audit covers everything above.
