Google Express Feed Specifications

Google Express is an interesting marketplace where you sell your products on Google. The conversion rates and CTRs are significantly better, especially on Mobile, and it’s very compelling to sell there.

The feeds are not so simple though, because the Google Express feeds require multiple steps with a product feed, local inventory product feed, and order and tracking feeds sent via the Google Content Shopping APIs.

The latter Google Express feed API involve Acknowledging the Order, Submitting tracking, and updating shipping through the APIs.

If you can get on Google Express, it’s well worth the effort as you can now be found on a great channel through web and mobile apps.

Jet Feed Specifications

Jet is a marketplace owned by Walmart, but run separately from them. It’s a great place for price comparison and for bulk buying.

Selling on Jet is done through listing products APIs rather than through feeds, and by adhering to the Jet Feed Specifications.

It’s a great marketplace to try selling assuming you can get your products to conform to the Jet feed specs.

FireFox 57 Jetstream BrowserBench Benchmarks

The new FireFox 57 has been announced, and I just got the latest copy and while it feels significantly faster, I decided to run the latest Browser Bench Benchmark against JavaScript performance.

The results are significantly worse than Chrome and Edge. This might just show how contrived the Jetstream benchmark actually is.


Rakuten Marketing

Rakuten marketing does affiliate, display, and search advertising.

Rakuten Marketing’s feed format isn’t too complex, but does have some import fields that should be properly optimized, like title, category, and description.

This is especially true for search feeds, as Rakuten Marketing functions as an agency by advertising on Google Shopping.

Conversant Feed Specs

Conversant is an interesting channel because they bought Commission Junction and keep gobbling up lots of affiliate channels.

Their feed specs aren’t terribly complex, but it is different than many other channels, with the usual suspects like product ID, description, title, and image links.

Using a feed platform like Feedonomics lets you easily create a feed for Conversant.

Cardpool Slow Email Delivery Times


I recently bought 2 gift cards from to make a purchase from for a friend’s wedding registry.

Cardpool has two delivery options, Email and Physical.

From their website it says:
Email Cards
Email gift cards are delivered via email. While it will typically only take ten minutes for you to receive your eGift card, it can take up to 1 business day if further verification is needed.

Physical Gift Cards
All physical gift cards are sent via FREE USPS First Class Mail and should arrive in 3-7 business days. During peak holiday periods and USPS holidays, delivery may take a little longer.

Because 3-7 business days is far too long, I opted for Email, because I wanted to purchase my item on WestElm immediately as it was for a wedding registry.

Here is the sequence of events:
Sept 11, 2017 8:29pm – Ordered gift card #1

Sept 11, 2017 9:23pm – Ordered gift card #2

Because I ordered via email, I was really hoping it would take only 10 minutes, but nope, I didn’t even get the gift card codes delivered the same day.

Sept 12, 2017 – 8:06AM – Card #2 is delivered

Sept 12, 2017 – 9:41AM – I emailed asking how much longer it would take to get my card #1.

Sept 12, 2017 -2:19PM – Card #1 is delivered

Sept 14, 2017  – 2:42 PM – I finally get a response from support saying:

Thank you for contacting! We do apologize for the long wait to receive a response and appreciate your patience regarding this matter. We are experiencing a high number of emails and we only answer them in the order we receive them.

Our processing center typically completes all electronic gift card orders within one business day of the purchase. The orders are very often shipped within a few hours, however there is some processing time involved as we verify the value of every gift card before it is sent. In some cases we may ask for additional verification and your order will remain pending until we receive the necessary documentation requested.


Not only did getting a response take over 2 days, but the information listed on their website implies it’s usually 10 minutes, not a few hours. 

Luckily nobody bought the registry item by the time I received both gift cards.

I’ve been a CardPool user for over 2.5 years, and this is a very upsetting experience, and makes me wonder if the few bucks I saved was worth the hassle.




How to create a Curalate Feed

Curalate is a platform that makes social selling easier.

While there aren’t very many fields in the Curalate feed specifications, you should make sure to optimize product titles, and have correct product groupings.

Curulate even has a direct Shopify API integration, but of course that means you don’t get to use any title optimization in between.
