Solved: Shopify Sessions Plummeted, Conversion Rate Doubled - Help!

Hi there,

Thanks for reaching out!

I've had a look at the situation you described with your Shopify store, and to be honest, it's a classic case of looking at the wrong numbers. What you see as a "weird turn" and a "big dip" might actually be the first sign that your advertising is starting to work properly. It sounds counter-intuitive, I know, but a drop in traffic isn't always a bad thing if the quality of that traffic goes up. Let me give you some of my thoughts on what's likely happening and how you should be thinking about it from now on.

The core issue here isn't your session count, it's your mindset. You've fallen into the trap of chasing a vanity metric, which is distracting you from the numbers that actually put money in your bank account.

We'll need to look at why fewer sessions can actually be a very good thing...

Right, let's get straight to it. Your sessions have dropped 75%, but your conversion rate has doubled to 2.36%. You need to stop panicking about the session drop and start celebrating the conversion rate. A 2.36% conversion rate in eCommerce is pretty healthy, depending on the niche. Many stores would kill for that number.

Think of it like a physical shop on the high street. Would you rather have 1,000 people wander in, browse for a bit without any intention of buying, and then leave? Or would you prefer 250 people to walk in, all of whom are actively looking for what you sell, with 6 of them making a purchase? The first scenario gives you high footfall (your "Online Store Sessions"), but no revenue. The second gives you less footfall, but actual sales. You're in business to make sales, not to have a busy website.

What's most likely happening is that your new Advantage+ Shopping campaigns are doing their job far better than your old manual campaign. Meta's algorithm is getting smarter. When you tell it to optimise for conversions (and I assume you're optimising for Purchases, if not, you absolutely should be), it doesn't just look for people who are likely to click your ad. That's an old way of thinking. It looks for people who have a history of actually buying things. These people are a smaller, more valuable group. They are more expensive to reach because every other advertiser wants to reach them too. But they convert.

Your old manual campaign was probably brilliant at finding cheap clicks. People who are curious, bored, or just like clicking on ads. They land on your site, have a look around, and leave. This inflates your session numbers but does absolutley nothing for your bottom line. The Advantage+ campaign is different. It's skipping the tyre-kickers and going straight for the buyers. This means fewer people clicking overall, leading to a drop in sessions, but a much higher percentage of those who do click are actually making a purchase. This is efficient advertising.

I'd say you need to understand what Advantage+ is really doing...

The introduction of Advantage+ Shopping Campaigns (A+SC) is probably the single biggest change you've made, and it's the key to understanding this whole situation. You said you don't know how it can mean lower sessions – it's because it's fundamentally a different beast to your manual campaigns.

A+SC is designed to be a "black box" on purpose. It automates a huge amount of the work, combining your prospecting (finding new customers) and retargeting (reaching people who've already visited your site) into one streamlined campaign. You give it your creative, your budget, and tell it to find buyers, and it uses Meta's vast dataset to do just that. It's not just about interests or demographics anymore; it's about behavioural signals that predict purchase intent with scary accuracy.

It automatically tests different audiences, placements, and creative combinations to find what works best. So, while your old campaign was stuck targeting the same manual segments you set up three months ago, A+SC is constantly learning and optimising. It's likely discovered that a huge chunk of your old audience was junk traffic and has simply stopped showing them ads, hence the massive session drop. It has identified the small pocket of users who actually convert and is focusing your entire budget on them.

I remember one eCommerce client selling a subscription box where we achieved a 1000% Return On Ad Spend.

Your job now isn't to fight the algorithm, it's to feed it what it needs: better creative, a clear conversion signal (your Pixel needs to be flawless), and a solid product offer. The machine will do the heavy lifting on targeting.

You probably should focus on the metrics that matter...

So, if Online Store Sessions is a vanity metric, what should you be looking at? From now on, I want you to basically ignore that number in your Shopify analytics. Instead, live inside your Facebook Ads Manager and focus on these three things:

1. Cost Per Purchase (or Cost Per Acquisition - CPA): How much are you paying in ad spend to get one sale? Has this number gone up or down since you started the A+SC tests? If you were paying £20 for a sale before and now you're paying £15, you are winning, regardless of what your session count says.
2. Return On Ad Spend (ROAS): For every £1 you put into Facebook Ads, how many pounds are you getting back in revenue? This is the ultimate measure of an eCommerce ad campaign's success. If your ROAS is higher with the new setup, you're doing something right. We worked with a cleaning products company and achieved a 633% return for them.
3. Average Order Value (AOV): Are the customers from the new campaigns spending more per order than the ones from the old campaign? It's possible A+SC is finding more affluent or more committed buyers.

If your CPA is stable or lower and your ROAS is stable or higher, you should be scaling your A+SC campaigns, not questioning them. The session drop is just a byproduct of a more efficient system. It's noise, not a signal.

To really understand what you can afford to pay for a customer, you need to know what they're worth. This is where most store owners go wrong. They think short-term. Let's do a quick, rough calculation for Customer Lifetime Value (LTV).

The real question isn't how low can my CPA go, but how high a CPA can I afford to acquire a great customer? The answer is in its counterpart: Lifetime Value (LTV). Lets make some assumptions for your store.

Now you have the truth. With an LTV of £180, a healthy 3:1 LTV:CAC (Customer Acquisition Cost) ratio means you can afford to spend up to £60 to acquire a single customer and still run a very profitable business. Suddenly, worrying about a £1 CPC vs a £1.50 CPC seems a bit silly, doesn't it? This is the math that unlocks aggressive, intelligent growth.

You'll need a proper campaign structure...

While Advantage+ is powerful, I wouldn't recommend putting all your eggs in one basket. You should think about your advertising in terms of a funnel. Your old manual campaign and your new A+SC are essentially just two different tactics. A proper strategy involves testing different approaches at each stage of the customer journey.

When we take on a new eCommerce client, we typically structure their Meta ads account to reflect this funnel. Here’s a prioritised list of audiences you should be thinking about. The further down the list, the "colder" the audience is.

META ADS AUDIENCE PRIORITISATION FOR ECOMMERCE

BoFu (Bottom of Funnel - Hottest Audience): These are people on the verge of buying. You need to get back in front of them with a compelling reason to complete their purchase, like a reminder, a small discount, or social proof.

• -> Viewed Cart / Initiated Checkout (in the last 7-14 days)
• -> Added to Cart (in the last 7-14 days)

BoFu - Previous Customers: Your existing customers are your most valuable asset. It's cheaper to get a repeat purchase than a new customer.

• -> Previous Purchasers (all time)
• -> Highest Value Customers (Top 25% by purchase value)

MoFu (Middle of Funnel - Warm Audience): They've shown interest but aren't as committed as the BoFu group. You need to nurture them with more information, show them different products, and build trust.

• -> Visited Landing/Product Page (in the last 30 days)
• -> Engaged with your Facebook/Instagram Page (in the last 30 days)
• -> Watched 50% of a Video Ad (in the last 30 days)

ToFu (Top of Funnel - Cold Audience): These people have never heard of you. This is where you find new customers. This is what A+SC is primarily doing for you.

• -> Lookalike Audience of your Highest Value Customers (1-3%)
• -> Lookalike Audience of all Purchasers (1-3%)
• -> Detailed Targeting (Interests, Behaviours that strongly align with your ideal customer)

Your Advantage+ campaign is trying to manage this whole process for you. However, running seperate, dedicated campaigns for some of these segments can be very powerful. For example, a dedicated BoFu retargeting campaign with ads specifically for cart abandoners can often be incredibly profitable. I remember one women's apparel client where we achieved a 691% ROAS. It gives you more control and more levers to pull than just relying on the A+SC black box alone.

This is the main advice I have for you:

To pull this all together, you need to shift your perspective and your strategy. Stop worrying about vanity metrics and start acting like a data-driven business owner. Here’s a summary of my main recommendations.

As you can probably tell, getting this right goes a bit deeper than just setting up a campaign and hoping for the best. The difference between a store that struggles and one that scales profitably is often this next level of strategic thinking, analysis, and disciplined execution. It’s about understanding the "why" behind the numbers, not just reacting to them.

This is the kind of process we go through with all our clients. We dive into the data, build a robust strategy, and then relentlessly optimise to drive real business results, not just website traffic. It takes experience to know which levers to pull and when.

If you'd like to have a proper chat where we can screen-share and look at your actual ad account together, we offer a free, no-obligation initial strategy session. It's a good way for you to get some concrete, actionable advice and for us both to see if we'd be a good fit to work together. Theres usualy a lot more that can be done to improve results.
