Searching for products on Google Shopping

Are poor product descriptions holding back your Google Shopping campaigns? 

If your Google product listings are too vague, you’ll lose clicks. If they’re too bloated, you’ll get cut off mid-sentence. Worse still, if your Google Shopping description doesn’t align with your eCommerce site’s product detail page (PDP), you risk confusing customers, losing trust, and tanking your conversion rates.

So, what’s the right approach? How should you optimize your product descriptions for Google Shopping? And how do you balance brand consistency with platform-specific optimization? 

This guide has the answers. Packed with practical, no-nonsense best practices, we’ll walk you through how to optimize your Google Shopping product listings for maximum visibility, better click-through rates, and more sales. 


To optimize for Google Shopping, prioritize consistency

First thing’s first, it’s important to prioritize a high-level of consistency between your Google Shopping descriptions and your PDPs.

There’s two simple reasons for this.

  1. A consistent description helps build trust with customers. If potential shoppers see one description on Google Shopping and another on your website, it might cause confusion or mistrust.

  2. Matching descriptions can improve your SEO and search engine ranking. It’s always a good thing to avoid conflicting information.

However, at the same time, your Google Shopping descriptions shouldn’t be word-for-word replicas of your website PDPs. When creating your Google Shopping descriptions, keep in mind…

Pay attention to character limits in Google Shopping.

Google Shopping Character Limits:

Google Shopping has specific character limits for product titles and product descriptions, so if you’re aiming to follow Google Shopping best practice, you’ll need to tailor your content to fit within these constraints.

Google Shopping titles can technically be up to 150 characters. However, because only 70 characters are typically displayed on Shopping ads and free product listings,

When it comes to descriptions, Google Shopping imposes a limit of a maximum of 5000 characters. However, again because Google only displays a limited number of characters for product descriptions in Shopping ads and free listings, . It’s best practice to list the most important details, such as size, material, intended age range or special features in the first 160–500 characters.

In contrast, no such hard constraints exist for Product Detail Pages on your website. 



It’s best practice to avoid symbols and special characters in Google Shopping listings

Aside from character limits, there’s plenty of other best practice and optimization tips to bear in mind for Google Shopping product listings. One major bugbear is the use of special characters and symbols – these should both be avoided for effective Google Shopping SEO optimization. Why? Well…

Avoid overuse of special characters such as trademark symbols.

  • Overuse of special characters, including trademark symbols, can sometimes delay or even block your Google Shopping campaign’s approval. This is because your special characters could be stripped out or encoded incorrectly on shoppers’ devices, which could lead to formatting errors in your Google Shopping feed. Naturally, this would send your product listing plummeting down in the rankings – not great for your Google Shopping SEO.

  • At the same time, as mentioned above, Google Shopping titles and descriptions only give you a limited word-count to play with – and special characters take up valuable space. Symbols like ® and â„¢ don’t add SEO value and may not be meaningful to shoppers. A cleaner listing without these symbols is better practice for Google Shopping – the listing won’t get blocked, and ultimately, it’s just more user-friendly.

  • You also shouldn’t use capital letters for emphasis within your Google Shopping description, because capitalized text is common in spam and untrustworthy ads. However, you should still use capitalization where it's appropriate, including for abbreviations, phone numbers, countries and currency. For example, 'ADHD', 'UNICEF', '1-555-CALL-NOW', 'UK' and 'USD', should all be capitalized. 



Google Shopping Best Practices

In summary, start actioning these Google Shopping optimization tips to ensure your products show up for your customers.

  1. Use the same core product information across your website and Google Shopping to ensure consistency, but tailor the descriptions to fit Google Shopping best practices.

  2. Include the most important information and keywords within the first 70 characters of your Google Shopping title.

  3. Emphasise key features and benefits in the first 500 characters for Google Shopping descriptions.

  4. Ensure your Google Shopping descriptions aligns with your brand tone and message.

  5. Avoid symbols, special characters, and unnecessary capitalization in your Google Shopping product listing.

  6. Always check Google Shopping’s policies to ensure compliant, optimized listings.

For effective optimization of your Google Shopping listings, you’ll need to find a balance between mirroring the content of your on-site PDPs and tailoring content to the platform’s specific requirements. Clear, concise, and well-structured descriptions improve both visibility and click-through rates, helping customers find the information they need quickly.

By prioritising key details in the first 500 characters, avoiding unnecessary symbols, and aligning with Google Shopping’s feed policies, you can create SEO-optimized product listings that perform effectively without compromising brand integrity. Keeping these best practices in mind will help you make the most of Google Shopping as a valuable sales channel.

Good luck!
