Online Store Advertising: Facebook, Instagram and Google
For most online stores, the most practical combination is Google for people who are already searching for a product, and Facebook and Instagram for discovery, reminders and repeat purchases. The channels should not be managed separately: order tracking, the product catalogue and the right audiences show which channel generates revenue, not just clicks.
Which advertising channels are right for an online store?
The choice starts with how the customer makes a decision. If someone is searching for a specific product or brand, Google Ads can reach them at the moment they intend to buy. If they are not familiar with the product yet, Facebook and Instagram can show how it is used, its look, its benefits or the promotion.
This does not mean that Google is always better than Meta, or vice versa. A spare parts store, for example, needs strong search, filters and clear product pages. For cosmetics, fashion, gifts and visually appealing products, a photo or video is often the first reason people take an interest.
| Channel | When it is useful | What is advertised | What is measured |
|---|---|---|---|
| Google Ads | The customer is searching for a specific product, brand or solution | Products, categories, searches and remarketing | Orders, revenue, order value |
| Generating interest and reaching new potential customers | Catalogue, video, carousel, offer | Purchases, add-to-carts, new audiences | |
| Visual presentation of a product and brand | Images, short videos, Stories and Reels | Purchases, visits, interactions and repeat visits | |
| Facebook and Instagram together | Reminding visitors and customers | Viewed products, abandoned carts, complementary products | Purchases and repeat ad frequency |
Google Shopping or product campaigns make sense when the product catalogue is well organised: name, price, availability, image, category and a correct link to the product. With Meta, the catalogue must also be synchronised with the store. An incorrect price, an out-of-stock item or a link to the home page leads to wasted spend and a poor experience.
How do you choose audiences without guessing?
An audience is not simply an age group and a city. For an online store, it is built around behaviour: people who visited a product page, searched the site, added an item to their cart, started checkout, bought once or bought more than once. These groups have different levels of readiness and should not receive the same ad.
For new customers, start with a broad profile if the store has enough data and a clear offer. Add interests only when they have a logical connection to the product. Too many restrictions narrow the audience and leave the algorithm with too few opportunities to find buyers.
For people who already know the store, use audiences of visitors and customers. Someone who viewed a specific product can be shown an ad for that same product. Buyers can be excluded from the first-purchase campaign and included in a campaign for complementary products, a new model or a repeat order.
In Google, the audience is linked to search and intent. Separate searches by category, brand and specific product. Also monitor the queries that actually trigger your ads. If you are paying for overly broad searches, add negative keywords and review the page your ad leads to.
What campaigns work for a product catalogue?
A campaign should have one clear objective. A sales campaign is not judged by likes, but by completed orders and revenue. An awareness campaign may have a different objective, but it should not be presented as proof of direct sales.
- 01Attracting new visitors
Show your strongest products to people who have not bought from you yet. Use a catalogue, short video or carousel. The message should explain what problem the product solves and why the customer should open this particular page.
- 02Bringing visitors back
Create a separate campaign for people who viewed a product or category. Show them the same product, a similar model or a genuine advantage of the store: delivery, payment method, warranty or easy returns.
- 03Recovering abandoned carts
Remind customers about an order they started but did not complete. Check that the ad is not shown after a purchase and that the retargeting window is not too long.
- 04Repeat purchase
Segment customers based on the product and the usual time until their next order. Offer a consumable, a larger pack, a new range or a product that logically complements their previous purchase.
On Google, the structure usually follows the catalogue and search behaviour: separate groups for important categories, specific products and branded searches. The ad copy should match the intent. Someone searching for a specific model should not land on a general page with dozens of unrelated products.
What ad messages convince customers?
The message does not start with “Buy now”. It starts with a reason to read it. For each product, prepare several different angles: a specific problem, how it is used, quality, comparison, seasonal need or delivery convenience.
A good ad leads to the same promise on the product page. If the ad talks about fast delivery, this condition should be clearly visible in the store. If it shows a discounted price, it should match the price in the cart. Mismatches reduce trust and make measurement more difficult.
Prepare different formats for Facebook and Instagram. A square product image is useful for the catalogue, but a short vertical video can show the product in use. Do not rely on one creative for the entire period. Track which versions generate quality visits and purchases, not just cheap clicks.
How are sales and return on ad spend measured?
Before the first campaign, you should track at least product views, add-to-cart events, checkout starts and completed purchases. The purchase event should pass the order value and currency. This allows the platforms and analytics tools to compare not only the number of orders, but also the revenue.
Test the tracking with a test order. Check whether it is recorded once, whether the correct product is passed, whether the value includes delivery twice and whether a rejected order is left recorded as a real sale. If needed, the website, advertising platforms and CRM system can be connected through API integrations to compare online orders with those actually confirmed.
The main metrics are ad spend, revenue from ads, number of orders, average order value and return on ad spend. The last metric is useful only when revenue is recorded reliably. It is not the same as profit: revenue must cover cost of goods, delivery, payment fees, returns and other expenses.
Compare periods and campaigns under the same conditions. If you change the price, delivery, product page and advertising at the same time, the result will not show which change helped. Reconcile the data with store orders and accounting information, especially for cash on delivery and rejected shipments.
What budget is needed to advertise an online store?
There is no universal amount that guarantees sales. The budget depends on the margin, average order value, competition, number of products, stock levels and whether the store already has visitors and customers. Separate the ad spend from the budgets for setup, management, creative assets and analysis.
| Cost | What it includes | How it is planned |
|---|---|---|
| Ad spend | Impressions and clicks on Google, Facebook and Instagram | Based on the target order volume and the acceptable customer acquisition cost |
| Campaign management | Structure, audiences, copy, settings and optimisation | The marketing service ranges from €250–€2,500; the specific price depends on the channels, number of campaigns and required materials |
| Store preparation | Catalogue, product pages, checkout and mobile version | For a new store, online store development ranges from €840–€6,300; complexity depends on the catalogue, payments, couriers and integrations |
| Measurement and connections | Events, analytics, pixels, catalogue and API | Assessed based on the platforms, CRM system, payment method and need for confirmed orders |
Start with a small but sufficient test period and define in advance what you will consider a success. Do not allocate the same amount to every channel just because they are popular. If Google captures demand while Meta builds interest, their roles are different and the results should be viewed in that context.
How should Facebook, Instagram and Google be combined in 2025?
The combination should follow the customer journey. Google captures intent, Facebook and Instagram create interest and bring visitors back, while the store and CRM system confirm whether the order is genuine. Someone may see a product on Instagram, search for the brand on Google later and complete the order after a reminder.
A practical structure is to have separate campaigns for new customers, visitors, cart abandoners, and previous customers. In Google, separate product searches from branded searches and monitor the queries. In Meta, use the catalog and different formats, but exclude people who have already purchased wherever the goal is a first order.
The store’s speed and clarity are part of the advertising. If the page loads slowly, the filters do not work on mobile, or cash on delivery and shipping information are hidden, a bigger budget will not fix the problem. With a complex catalog like the one on Q-Parts.bg, search, filters, and courier integration are essential to the purchase decision itself.
Before launch, review the product feed, mobile cart, stock levels, return policy, tracking codes, and order confirmation. Then review not only the ad accounts but also the actual orders. That is where you see whether the campaign is generating business, rather than just activity.
Frequently asked questions
Are Facebook or Google ads better for an online store?
It depends on the product and how customers search for it. Google is strong when there is clear intent, while Facebook and Instagram are useful for discovery, visual presentation, and remarketing.
How much money do I need to start advertising?
There is no reliable one-size-fits-all amount without data on the product, margin, and competition. Plan the advertising investment and management separately, start with a clear hypothesis, and do not evaluate the campaign based on clicks alone.
How can I tell which ad generated the order?
Set up events for product views, carts, payments, and purchases, and pass through the order value. Then compare the data from the advertising platforms with actual orders, confirmed payments, and refused deliveries.
Do I need to advertise all products?
Not necessarily. Start with products that are in stock, have a clear profit margin, a good product page, and a logical reason to buy. Then expand the catalog based on actual results.
