If you have an e-commerce business, it’s important that you have a Google Shopping strategy. Google shopping is powered by Adwords and Google Merchant Centre. However, unlike Adwords, where text ads, campaigns and ad groups are focused around keywords of your choice, with Google Shopping, Google determines when your ads show up. This makes it closer to natural search. As an SEO marketer, it’s your job to make Google think your ad is the most relevant one for the user’s search query.

If you’re a copywriter, your main focus will be the title and description. The title will be the text that is shown when your ad is served. Then, the description will the text that is shown once your ad is clicked on. Here’s an example:

How long should my Google Shopping ad title be?

There’s not a lot of space to play with when it comes to Google Shopping titles. Google Merchant Centre lets you submit titles up to 150 characters. However, it advises keeping the title character limit to around 70 as this is the maximum amount they display. You can see that some of the examples above have ignored this rule and have been truncated, which looks a little messy. Stick to around 65 characters.

How long should my Google Shopping ad description be?

Descriptions obviously have a little more wiggle room that titles. Google allows up to 5000 characters for product descriptions. But let’s be honest, the majority of people won’t read it a description that long. It’s advised that you keep your product descriptions between 500 and 1000 characters long, with the most important information coming first.

What information should my Google Shopping description include?

The Google Shopping SERPs will only show the first 145-180 characters of your product description, so make sure you get straight to the point. As you’re limited for space, the most important information should be highlighted in the first couple of sentences. This should include:

  • Size
  • Shape/Style
  • Colour
  • Design
  • Material
  • Special features
  • Any Technical details

Not all of these will be applicable to your product, but try to include as much relevant information as you can.

Can I use keywords to optimise my Google Shopping ads?

If you have a short title, try to make the most of your character count by adding some keywords to it.

For example, ‘Charlotte Olympia Black Kitty Flats’ can become ‘Charlotte Olympia Black Kitty Flats. Women’s Size 5 Suede Flats.’

Here, we’ve just added some relevant information to the title (but still keeping it under 70 characters). If you want your product to rank for a specific term, for example ‘suede flats’ make sure you include it in the product title, and not just in the description.

However, research suggests that Google’s algorithm sees the words at the beginning of the product title as the most important factor when it selects which ads are most relevant for the search query. Therefore, it is important to make sure you put the search term you most want to rank for first.

Is there anything I should avoid in my ad description?

Google has certain requirements and guidelines when it comes to writing shopping ads – but it also has things that it does not recommend. It’s important that you take these into account when writing your shopping ads, as Google will penalise rule breakers. Here’s what you shouldn’t include in your description.

  • Block capitals or special characters: They look gimmicky and are a technique often used in spammy ads.
  • Comparisons to other products: For example, ‘much more comfortable than X’
  • Foreign words: Unless they are commonly understood. For example, the word ‘ramen’ is widely used outside Japan.
  • Promotional text: Such as sale price, sale dates, delivery, delivery dates or other time-related information.

In addition to this, it’s important that you use correct grammar and spellings as it not only looks more professional but is also something that Google rewards.

By following Googles guidelines and writing clear, concise, optimised titles and descriptions, you will have a greater chance of featuring more prominently on Google Shopping. However, it’s important that you also focus on creating enticing product descriptions so that customers convert once they actually get to your product page.
