Google Shopping is a wonderful tool for merchants to sell their products and in many ways can be compared with SEO.

The same principles apply and the process is similar behind creating product titles.

With Google Shopping Campaigns, however, you don’t have the opportunity to choose what keywords your ads should use since Google will automatically match the titles in your Google Shopping feed with searches in Google and your ads will appear when appropriate.

Besides, Google will also look at your overall google shopping feed quality to determine when your ads should show by just matching search queries with your product titles.

Here Are 4 Ways You Can Optimise Google Shopping Campaigns

1.Optimise Your Google Shopping Data Feed

Google loves frequently updated information and also you need your products to be accurate.

So each time there’s some change regarding your products like price, shipping or on the product description, update your data feed.

Equally as important is running a test data feed, which submits your information to the Google Merchant Center for troubleshooting prior to including products in the search listings.

Using Google Shopping isn’t necessarily difficult and if you’re selling products online you should be taking advantage of every opportunity to drive qualified traffic back to your product pages through the program. Some of the key product attributes you should be optimising in your feed.

Product Titles

You don’t have to use the same product title that you use on your website in your Google shopping data feed.

Retailers generally tend to go with short product titles on the website, typically 40 to 50 characters in length. Whilst this may be suitable for the website, you are losing out on valuable clicks by not making use of the Google shopping title length of 150 characters. The more information you add to the product title including keywords, the better it is for conversions and impressions.

Adding commercial intent adjectives like promotion or offer can be a way to ensure you get impressions from these very highly sought-after searches.

And this is true especially for product categories where the price means a lot and you can compete on the price, it will be efficient to include these words.

Product Descriptions

Although Google allows up to 5000 characters for product descriptions, no one is going to have the patience to read through all of that in your product listing ad. The ideal limit that most retailers look at is around 500 to 1000 character descriptions.

As mentioned earlier in this article, Google shopping can be optimised similarly to how you would SEO a website. So look at product descriptions as meta descriptions and follow similar principles while optimising these. Again, using the right keywords is the key.


Some key factors while optimising your images for Google Shopping Ads

2.Negative Keywords

This is a very critical part of optimising your Shopping Campaigns and begins with you having a closer look at the search terms that are triggering your google shopping ads.

The search terms report shows you what keywords people searched for before they clicked on your product listing ad (PLA)

Sort the list based on cost and filter out queries that are not relevant to your business but are still costing you monies. Add these to the negative keyword list.

Next sort by impressions and again filter our irrelevant search queries that are triggering your ads and add these to the negative keyword list.

Next, have a look at the search terms that have a competitor’s name, if these are not profitable to you filter these out as well.

Lastly, look at generic keywords related to the products you sell, if these do not get you conversions or have poor click-through rates, it would be a good idea to add them to the negative keyword list as well.
