Short answer
Before fine-tuning bids on board game ads, check the data: a single title can exist as a base game, an expansion, a separate edition, a localised version and a bundle. A workable foundation consists of a clean query taxonomy, a catalogue with distinct entities, and a feed that describes each physical product accurately. Measurement completes the system: the purchase remains the primary action, and every order receives a unique transaction identifier.
The Merchant Center product data specification includes the base attributes id, title, description, link, image_link, price and availability. The status of other fields depends on the category, country and format. That distinction matters: not every field is required for every game, but every value you send must be truthful and consistent with the product.
Query taxonomy: what answer the person expects
Before building campaigns, sort queries by the page that best matches the intent. If someone needs rules or a comparison, a product page will not always be the appropriate answer. If they name a specific game, edition or expansion, they need the exact product page.
| Intent type | Example phrasing | What to answer with |
|---|---|---|
| Specific title | game name + "buy" | Base game page |
| Edition or localisation | name + "in Ukrainian", "deluxe" | Page for that specific edition |
| Expansion | name + "expansion" | Expansion page |
| Mechanic or genre | co-op, deduction, card games | Collection or filter |
| Group composition | for two, for a group, family | Curated collection |
| Occasion | gift, party, travel | Selection with stated criteria |
| Rules and support | rules, how to play, PDF | Content or service page |
| Accessories | sleeves, organiser, playmat | Page for a compatible accessory |
This is an internal analysis model, not demand statistics. It helps separate navigational intent, where the person is still comparing options, from transactional intent, where a product has already been named. For each group, fix the target page, the permitted ad formats and the queries that must be excluded.
Check ambiguous titles separately. A title may coincide with the name of a book, a film, an app or an ordinary word. In that case, look at the full query and the actual page rather than drawing a conclusion from a single word.
Catalogue architecture
The catalogue should reflect what the buyer actually receives. It helps the team to fix several entity types:
- Base game. A standalone base game with its own
SKU. - Expansion. An add-on sold separately that may require the base game. It is not a variant of the base.
- Edition. A deluxe, anniversary or updated edition with its own contents.
- Language edition. A separate language version, if the box, components, rules or identifier differ.
- Bundle. A set with clearly described contents and its own
SKU. - Preorder. A sales status of a specific product, not a new title.
- Out of stock. An
availabilitystate that must appear identically in the catalogue, the feed and on the page.
For an expansion, state the dependency on the base game explicitly in the title and description, where such a dependency exists. For a bundle, list the contents. For an edition, show that edition's own box and specifications. This lets the buyer tell the products apart before reaching the cart, and gives the ad system unambiguous data.
Do not merge entities simply because they belong to the same series. A base game, an expansion and a deluxe edition answer different queries and may differ in price, availability and landing page.
The feed: titles, descriptions, identifiers and images
Title. Use a consistent template: game name, product type, edition or language, where these distinguish the SKU. For an expansion, add the word "expansion" so it is visible without reading the whole description.
Description. Give the facts needed to make a choice: what is in the box, what language the components and rules are in, whether the base game is required, what makes the edition distinctive. Report player count and age marking as the manufacturer stated them, without widening the range yourself.
Identifiers. Send brand, GTIN and MPN in line with the attribute rules and the manufacturer's data. Do not copy one GTIN across different physical products, and do not create a number yourself. If the manufacturer has not supplied an identifier, fill the fields according to the current specification rather than inventing values.
Images. The main photo must show the specific product. Do not substitute the base game box for an expansion, or the cover of a different language version. The buyer should recognise the product they receive from the ad and the page.
Price and availability. The data source for the feed, the product page and checkout must be consistent. A preorder should not be marked as in stock. After a change to contents or a promotion, verify that the update has reached every surface.
When to use item_group_id
The item_group_id help article describes variants as separate products with unique id values and a shared group identifier. The grouping must match the choice available on the landing page; values should not be reused for another product or changed frequently.
For board games, grouping can be appropriate where the difference remains a variant of the same product — for example, the colour of an accessory or the size of a playmat. It is not suitable for pairs such as:
- a base game and an expansion;
- a standard and a deluxe edition with different contents;
- a standalone product and a bundle;
- different games in the same series;
- language editions with different contents or independent-product characteristics; language or a distinct GTIN alone is not a sufficient grouping rule.
Before grouping, open the target page. Does the buyer see exactly the variant that appeared in the ad? Do its image, price, availability and identifier match? If there is no clear answer, it is better to keep the products separate.
Checking landing pages
The Merchant Center landing page requirements expect link to lead to the page of a specific product, not to a category, a search or a general page. The title, description, image, price, currency and availability must match the data in the feed. Material information must not change depending on device, browser, location, cookies or user agent.
Check URLs on a phone and a desktop, in a clean session and while logged out:
- the correct edition or language version is selected;
priceand currency are visible before adding to the cart;- the availability status matches the feed;
- the image shows the same
SKU; - there is no forced redirect to a
categoryor another country; - the page is accessible to the crawler and does not show it a different product;
- the expansion states the base game required;
- the bundle describes its contents clearly.
Repeat a spot check after site releases. A change in routing, localisation or the inventory system can break consistency even without any edit to the feed itself.
Search and Performance Max: divide the roles
In Search, keywords give you an explicit way to work with specific titles, editions, expansions and accessories. The group structure should follow the landing pages. A query about an expansion should not be sent to the base game just because they share a series name.
In Performance Max, search themes are an optional broader signal that gives the system context missing from creatives, the feed or the landing page. They are not keywords and not a hard limit on impressions. Google advises adding new information, avoiding repetition and near-duplicate phrasing, and keeping themes broad enough.
For this category, themes can describe a mechanic, a use situation or a type of assortment that is not visible from product titles. A list of all titles would duplicate the feed and explain little about the structure of demand. After launch, review the actual queries, separate out service intents such as rules or free materials, and adjust exclusions in line with what you actually see in the report.
Do not carry a negative keyword list between campaigns without checking it. The word "rules" may be an informational query for a base game, yet a useful part of a query for a rulebook or an accessory, if such a product really is on sale.
Measuring purchases
The purchase should be the primary business action. Product views, add-to-cart and checkout starts are useful for diagnostics, but they do not become equivalent to a sale simply because there are more of them.
According to the conversion goals help article, conversion actions are grouped into goals, and a Purchase goal may contain several purchase-related actions. The composition of the goal affects optimisation, bidding and reporting. Check exactly which actions are included in Purchase, and remove those that do not confirm an order.
For each purchase, send a unique transaction ID generated by the backend or the e-commerce platform. This helps minimise duplicates when the confirmation page is opened again. The same ID across different orders, by contrast, causes undercounting.
When checking, reconcile ad conversions against real orders using the same identifier. Record returns and cancellations separately in your internal system. Do not assume they already flow into ad reporting: that depends on how the import and adjustments are actually implemented.
Symptom, check, action
| Symptom | What to check | Action |
|---|---|---|
| An expansion shows as the base game | SKU type and a shared item_group_id |
Split the products and fix the grouping |
| Buyers confuse editions | Title, photo, language and description on every surface | Refine the attributes and replace the mismatched image |
| Merchant Center sees duplicates | id, GTIN and variant groups |
Give each physical product back its real data |
| Price or availability does not match | Feed, page and checkout | Sync the source and repeat the check |
| The page is not accessible to the crawler | Redirects, user agent, geography, cookies | Remove selective serving and check the URL again |
| Irrelevant queries have appeared in PMax | Search themes and actual queries | Remove duplicate themes, add justified exclusions |
| More conversions than orders | Repeat tag firing and transaction ID | Send a unique ID from the backend |
| Optimisation counts micro-events as purchases | Composition of the Purchase goal | Keep only confirmed purchases in the goal |
Launch checklist
- The catalogue is split into base games, expansions, editions, language versions, bundles and accessories.
- Every SKU has a stable
idand genuine manufacturer identifiers, where these exist. - Titles make it possible to tell a base game from an expansion, and one edition from another.
- Descriptions contain the facts needed to make a choice, with no unverified properties.
item_group_idis used only for genuine variants.- Every
linkleads to the page of a specific product. - Price, currency, availability and images match between the feed and the site.
- Search themes add new context rather than duplicating the entire catalogue.
- The Purchase goal contains only relevant actions.
- The transaction ID is unique and comes from the backend or the shop platform.
Weekly review
- Review new SKUs and status changes: entity type, identifiers, images,
price, availability. - Work through each new
Merchant Centerdisapproval by its specific reason. - Spot-open landing pages from the feed in a clean session and on different devices.
- Review actual queries, especially ambiguous titles and service intents.
- Check search themes for repetition and for phrasing already fully described in the feed.
- Reconcile purchases against internal orders by transaction ID.
- Check the composition of the Purchase goal after changes to tags, analytics or the import.
Review the taxonomy itself from time to time. A new edition, localisation or bundle changes more than the assortment: it adds a new entity, a new landing page and a separate intent. If the catalogue captures these differences, the advertising is easier to diagnose without assumptions about the niche behaving "specially".

Which box does the buyer receive after clicking?
Shopping should open the exact product, not a general collection. In Search, distinguish game title, language, expansion and informational queries. Meta creatives can explain the play scenario and contents without claiming properties the manufacturer has not substantiated. This guide covers physical game retail: informational content can support selection, but its views are not purchases.
| What is sold | Explain | Destination |
|---|---|---|
| Base game | Edition, language and box contents | That specific game’s page |
| Expansion | Required base game and compatibility | Expansion page stating its dependency |
| Bundle | Complete contents and set price | The bundle page, not one component |
Variants and bundles: a shared title is not enough
A different GTIN or language alone does not determine variant status. Compare contents, page choices and current grouping rules. Google describes optional variant_option and item_group_title; check generator support. is_bundle has separate rules for a retailer-created bundle with a main product, not every game box. Search themes add PMax context but do not restrict impressions to an exact query list.

Board game store advertising questions
How should a board game store start advertising?
Choose items customers can actually order and reconcile title, edition, language, photo, price and stock with the feed and page. State the required base game for an expansion. Separate purchase queries from rules searches or comparisons. Test the mobile basket and a purchase event with a unique order ID. Then agree channels, budget and test criteria; correct data does not guarantee store sales.
Why should a base game and expansion be separate?
They answer different needs and can have different contents, prices and stock. An expansion buyer must know whether a base game is required and which version is compatible. Do not substitute the base box photograph or group items just because they share a series name. Reconcile SKU, description, identifiers and destination. Offer a bundle separately and clearly where it genuinely exists as one purchasable order.
How should game language and edition be handled in Shopping?
Show the edition the buyer receives: title, component and rulebook language, contents and its own box photograph. Use genuine manufacturer identifiers, not another product’s numbers. Language or a distinct GTIN alone does not determine grouping; check real differences and current specifications. The link should open the intended item, with price and stock matching the feed and basket on both mobile and desktop devices.
Are PMax search themes the same as keywords?
No. They add context that may be missing from the page, feed or creative, but are not an exact list of permitted impressions. Do not copy every catalog title into themes or treat a theme as a guaranteed query. Review actual search phrases and justified exclusions. The word “rules” can indicate information or a genuine product; the decision depends on assortment and destination, not one word.
Can a board game preorder be advertised?
First verify that the item can genuinely be ordered, with agreed payment terms and an expected dispatch date. Page messaging and feed data must match; do not present a preorder as in-stock inventory. Review format requirements and purchase availability in the target country. Explain possible timing changes without inventing a guarantee. Record confirmed orders, cancellations and returns separately; an inquiry by itself is not a sale.
