Performance optimization helps increase SEO, engagement, traffic, and conversion rate.
Conversion rate optimization increases the value of your inbound traffic.
Crush Pics automatically compresses your website images to make your site load faster.
- Automatically compresses your product, asset, collection, and featured article images
- No quality loss if you choose “lossless” compression
- Faster website = higher conversions, SEO rankings, engagement, traffic, and revenue
Crush Pics is a quick win to make your site faster, improve your SEO rankings, and increase engagement and conversion rate.
Images are generally the heaviest part of a web page. You can manually compress them (boring), or you can just install Crush Pics to automatically handle it for you (and any future images you upload).
There’s a free version, but for most stores it’s worth it go with a paid plan ($5/mo) to compress more images automatically.
Bonus feature: You can also mass update your image “alt” attributes and file names to make them more SEO friendly (available on paid plans).
A faster website improves most of your key metrics, so investing in improving your speed is an easy positive ROI.

AMP by Shop Sheriff
AMP (Accelerated Mobile Pages) is a Google backed project that makes mobile pages load faster.
When your pages are formatted with AMP’s code guidelines, they get cached by Google servers and pre-load during search results. This makes your mobile pages load instantly from Google search.
AMP by Shop Sheriff automates this process and has a visual editor to customize your pages.
- Instant loading mobile pages
- Lightning bolt badge in mobile Google search results
- Studies show increase in SEO, engagement, and conversions
I wrote an in depth guide here: Shopify AMP Guide.
The app is pretty easy to set up, has a free trial, and doesn’t modify your existing theme/pages, so feel free to check it out and experiment.

We built this app 👨💻 so if you want more features contact us.

Automation is probably my favorite topic in ecommerce marketing. There’s a beauty in setting up a good foundation and generating automated sales forever.
Klaviyo focuses on smart email automated marketing for eCommerce stores.
- Amazing automated flows, templates, and segmenting
- Insane amounts of analytics and data tracking
- Easy to use, and lots of pre-set flows to setup
I just started using Klaviyo this year and maaaaan I was blown away within 5 minutes of installing the app. Here’s a post about my experience: automated email marketing with Klaviyo.
If you like automated marketing, you’ll love Klaviyo.
The ease of segmenting and automation is incredible.
Multi-sequence abandoned cart emails are nice (and included), but what I think is really cool are things like advanced tagging and segmenting for delivering specific email sequences to customers that purchased specific products or from specific collections (great for cross selling).
You can send re-engagement campaigns too… example “If customer purchased something in the last year but hasn’t purchased (or visited site, opened email, etc) in the last 6 months, send a special offer”.
Those are rough examples. If you want help setting up detailed flows like this, we can help you out just give us a shout.
Price: Starts Free then scales up based on subscribers
*It’s more expensive than other email apps I’ve used, but if you set up the automated flows you should have no problem stacking a nice ROI.
Shoelace – Intelligent Instagram and Facebook retargeting on autopilot.
That’s a screenshot of a store I worked on getting about 10,000 monthly sessions.
- Automated way way to increase sales, conversion rate, and customers
- Creates sophisticated “customer journeys” and gets smarter over time
- Onboarding specialist + quarterly reviews make sure your ads are dialed in
Remarketing / retargeting is key because most customers need to interact with your brand multiple times before purchasing, and most visitors won’t convert the first time. Remarketing solves this by reminding about you after they leave your site (usually on Facebook, Instagram, or the web).
Shoelace works best if you’re doing at least a few thousand $$$ in monthly sales. If you’re not sure whether your store is at the level that would get a positive ROI contact us we’ll check it out and give our best advice.
You don’t need an app for retargeting, it just helps automate some processes. If you need help setting up a good retargeting system contact us — P.S. everyone should have a good retargeting system 🧙♂️
Klickly – Automated inbound traffic
Klickly might be my favorite inbound traffic app… and it’s free!
It’s like having a PPC manager steadily creating ads, but with no ad spend and you only pay a commission on conversions like referral marketing. Nice!
- Commission based ads (no app fee, no ad spend)
- Runs on autopilot
- Guaranteed +ROI for any sized business
I experimented with Klickly and shared a 30 day snapshot here, getting 3K clicks in a month and generating a 3.6 ROAS.
Price: commission based
I believe Klickly is only available for USA advertising, but that might change as they expand.
Get people interacting more with your site and closer to making a purchase. Increased engagement and page views also helps your SEO.
This powerful yet easy to use rewards program app generates more repeat customers, brand loyalty, and customer referrals. It also has over 3,000 reviews in the Shopify app store.
- Easy to setup rewards and referrals program, runs on autopilot
- Create engagement actions to earn points and rewards (discounts, free shipping)
- Create VIP tiers to encourage brand loyalty and give special bonuses
Examples of how customers can earn points (these are customizable):

Side Bonus #1: Capturing more first time visitors. When you have Smile, it creates an icon on your site that people can click to see a popup of your rewards program. Set it so people earn points by signing up and you’ll captured new potential customers (and email address) that are interested in your brand.
Side Bonus #2: Be a cool brand. Creating more engagement, rewarding your loyal customers, and providing referral incentives all strengthen your brand’s community.
People like seeing other people using your product. Social proof is a great way to increase your conversions while building community around your brand.
Judge.me is the best reviews app on the market. It’s packed with features, built with performance in mind, and easy to set up automated systems.
This is a must have app for every Shopify store.
- Automatic review requests, featured review carousels, social sharing
- Engagement features like questions, discount incentives, picture uploads

Judge.Me has too many features to list – it’s a super powerful reviews+ app that increases engagement and breathes life into your store with reviews and questions/answer features.
I’ve personally been watching this app grow over the last few years from a small reviews app to a feature-packed, speed optimized, well designed go-to Shopify app.
It’s insanely low priced, has great support, and you can easily import reviews from anywhere.
Price: Free for basic, $15/mo for all the goodies.

Refersion is an easy to set up full-featured affiliate marketing platform.
Referral programs give you social proof, backlinks (great for SEO), and no-risk referral traffic. They also build community by connecting with people that vibe with your brand.

The Order Automator saves time by automating order tasks like fulfillment and order tagging.

I think Rewind is a key Shopify app for stores doing volume.
Your online store is the home base of your ecommerce business. Shopify backs up some things, but Rewind backs up EVERYTHING.
Rewind backs up your store’s data every single day:
- Products and Product Images
- Inventory, Customers
- Orders, Collections
- Blogs and Blog Posts
- Themes and Theme Files
- Menu Navigation
- Store Policies
- Shipping Zones
- Gift Cards
- Customer Saved Searches
- Metadata (for Enterprise plans)
The kicker for me to start using Rewind was realizing that blog posts aren’t backed up with Shopify – Losing years of content / traffic would be disastrous. You could manually do this if you enjoy the process of data backup (I don’t), so an automated app is a nice time saver.
It’s free for orders up to 100/mo then scales with the size of your store. I consider Rewind an insurance policy to save time, money, and reputation if a person or app accidentally screws up your store.
Growth is all about experimenting, trying new apps, and executing new marketing tactics.
We have experience using all of these apps so if you need help setting up for success let us know how we can help.
