Online Stores That Sell!

A great product is fundamental but what's as important is to know how to sell it. The internet offers it's users plenty of possibilities, to catch the attention of your customers you need to know how to stand out. JustIdea knows just how to do it, that's why we build online stores, that attract buyers and improve the shopping experience making it a pure pleasure.



We use the best e-commerce solutions, such as PrestaShop or WooCommerce. Our designers team has extensive experience in UX and UI design. Thanks to that, we can create dedicated solutions and custom graphic designs for our clients. Online stores under JustIdea's wings also undergo detailed audits, so they can be optimized and positioned properly.

Build one coherent shopping experience: connect your sales channels into a single ecosystem

Modern e-commerce does not end with a single traffic source. Customers move fluidly between ads, social media, search engines and newsletters, which is why an omnichannel strategy keeps their attention and increases order value. At JustIdea we build integrated buying journeys that connect every brand touchpoint into one predictable, data-driven system.

We use data and artificial intelligence to understand user behaviour regardless of channel: their interactions, segments and purchase intent. That lets us pinpoint which activities actually drive sales and which need optimisation. Our approach to omnichannel combines automation, AI and performance marketing strategy, so your brand is visible, recognisable and consistent everywhere your customer appears.

Meta Ads for E-commerce

Meta ads (Facebook and Instagram) are one of the most effective sales channels in e-commerce, provided they are run strategically. At JustIdea Agency we build campaigns that do more than drive traffic: they sell products and build repeatable revenue. Using artificial intelligence, we analyse user behaviour, segment audiences and automatically match creative to purchase intent. AI helps us identify conversion patterns faster, so we can scale budgets precisely where they return the most. In practice this means your Meta Ads campaigns are not based on intuition but on data: we test creative automatically, optimise delivery schedules and use predictive models to forecast customer acquisition cost (CAC). Your store gains a stable, measurable and scalable sales engine.

Google Ads for E-commerce

Google Ads is the foundation of profitable online sales. At JustIdea we design campaigns that combine the precision of data with the flexibility of AI algorithms to maximise return on ad spend. Our e-commerce strategies do not stop at classic shopping campaigns: they cover the full ecosystem, from Performance Max and dynamic remarketing to advanced YouTube Ads and Google Discovery. We use artificial intelligence to analyse conversion, margin and user behaviour data in real time. That lets us adjust budgets, bids and ad messaging on the fly, so every unit of currency spent in Google Ads works towards real sales rather than clicks alone. AI also helps us anticipate seasonality, spot new buying trends and recommend where to take a campaign next, before the market data makes it obvious. The result: Google Ads campaigns that are smarter, react faster to change and work in full synergy with your other e-commerce channels.

SEO for E-commerce

Effective e-commerce SEO today is no longer about keywords and links alone: it is precise work on data, user behaviour and sales potential. At JustIdea we build SEO strategies that support the entire buying journey, from the first brand contact to checkout. Integrating AI tools lets us analyse hundreds of queries, product categories and competitors in real time, and point to the directions that actually generate sales. AI supports us in content audits, search intent analysis and assessing how well product pages match their target keywords. We identify visibility gaps automatically, monitor seasonal trends and recommend changes before organic traffic drops. Our SEO strategies are designed so that your store steadily increases visibility, conversions and average order value (AOV), not only in Google but also in the new AI-driven search ecosystems such as ChatGPT, Copilot and Gemini.

Marketing Automation for E-commerce

An effective e-commerce business sells around the clock. With Marketing Automation we build integrated communication paths that react automatically to user behaviour: they recover abandoned carts, recommend products and build customer loyalty. At JustIdea Agency we design automations that work not only in email marketing but also in SMS, push, social media and remarketing, creating one coherent sales ecosystem. Artificial intelligence supports every stage, from customer segmentation to dynamically matching content to purchase intent. We analyse purchase history, visit frequency and average order value so the system can decide on its own when, what and to whom to show something in order to maximise conversion. With data-driven automation your communication becomes more precise and your campaigns more effective, without managing every step by hand.

Profit Analytics and Data Warehouse for E-commerce

In e-commerce every click, every transaction and every customer action is data: vast amounts of information that only becomes useful once it is collected, analysed and turned into business decisions. At JustIdea Agency we build Data Warehouse and Profit Analytics solutions that become the central data management system for your company. Every data source, sales, marketing and logistics, lands in one place where it is processed and analysed for sales growth and profitability. Our data warehouse implementation lets your company act faster, more precisely and more efficiently. We support it with analytics automation and AI algorithms: the systems learn the relationships between channels, products and customers, then recommend specific changes, for example which products to promote, where the marketing budget returns the most, or which customer segments hold the most promise. The outcome is not only full visibility into your data but the ability to make better business decisions, faster than your competitors, thanks to historical analysis and trend forecasting. You gain higher profitability, better budget control, faster detection of anomalies and optimisation opportunities.

Surf Inc.

I’m the CEO of a clothing brand. We’re focused on lifestyle clothing and accessories. Our headquarters are in Krakow, Poland but we wanted to expand to the western market. To do this, we brought in JustIdea to build us a webshop. We started working with JustIdea around March 2017, and it’s an ongoing engagement. Our business has grown like crazy during these past few years. The e-commerce aspect, in particular, has grown by at least 200%. We’re also drawing more traffic into our website because of their social media marketing work.
JustIdea is always one step ahead of us; they think about what we can improve, even if we don’t mention it. They’re always analyzing and going deep with any case, and the results are usually above our expectations.

NatureStyle

I’m the founder of naturestyle.pl, a high-end furniture shop. We wouldn’t be where we are had it not been for JustIdea Agency. We needed someone to create our e-commerce store.
We were experiencing a lot of administrative issues when we first started the shop, but JustIdea’s work has alleviated much of that burden.
They’ve automated many of our processes, so overhead costs have lowered drastically. Our annual sales have also skyrocketed. In 2018, we were making $3000 a month of sales profit, and currently, our monthly sales have gone up to $100,000. I’m very, very pleased.

Optimum

Mattress producing, family company. I'm a minority owner. We requested from Justidea design logos and online, presta-based shop for a new brand of mattresses.
We are happy about the results - a custom Presta shop adhering to our overall vision. They proved to be flexible and understanding.
It was not easy to work with us as due to the pandemic and other factors, we suffered many setbacks in developing the products we are selling in this online shop.

FAQ: online stores and e-commerce services

Frequently asked questions:


Will I have visibility into progress and the option to consult as we go?

Yes. Our cooperation includes access to our communication platform, ActiveCollab. It gives you ongoing visibility into progress and direct contact with the specialists assigned to your project.


Does JustIdea advise which platform to choose for my business?

Yes. We start with a workshop that identifies your key needs and challenges. On that basis we run a detailed analysis and prepare recommendations matched to your specific business goals.


Does JustIdea offer integrations with external systems such as ERP?

We do not handle that directly, but we work with proven technology partners whose support we use regularly. That means this area can be taken care of as part of the wider project.


Does JustIdea help launch an online store abroad?

Absolutely. We can take care of the whole project: building the online store, running marketing and then growing on foreign markets.


Does JustIdea help increase sales and visibility for an online store?

Yes. Performance marketing (paid campaigns) and SEO are two core areas of our expertise.


Does JustIdea build online stores from scratch, or also optimise existing ones?

For stores built on PrestaShop and WooCommerce we provide the full range of services. We can deliver a project from scratch, or take over and develop an existing store.


Does JustIdea handle graphic design and store UX?

Yes, that support is included.


Can I count on technical support after the store goes live?

Yes. We offer several cooperation models and match them to each client's individual needs and goals.


Can I commission both the store build and the marketing campaigns from JustIdea?

Yes. We offer end-to-end service covering both the store implementation, from design to launch, and full marketing support. As an agency we specialise in B2B, performance marketing and scaling e-commerce, which lets us combine the technical side with our clients' marketing goals.


Can I commission ad campaigns and SEO as part of the cooperation?

Yes, these are two core areas of our work. We run paid campaigns (Google Ads, Meta Ads, LinkedIn Ads) as well as complete SEO, covering audit, strategy, technical and content optimisation. Cooperation can include both channels in parallel, which helps build coherent and effective sales funnels.


Is cooperation possible on a retainer or in stages?

Yes. We offer flexible models, including monthly retainers (for example ongoing marketing support) as well as projects delivered in stages. Together with the client we agree the model that fits the scope and the schedule best.


Can the project be delivered in stages?

Yes, we very often deliver projects in stages. It lets us plan the rollout precisely, test the key features and run marketing or sales activity in parallel. This model works particularly well for larger stores or for expansion into new markets.


Does store design include adapting to mobile devices?

Yes. Every project we deliver is fully responsive and adapted to mobile devices. Our clients care not only about how it looks but about high conversion from mobile, which is why we put strong emphasis on interface optimisation and loading speed on phones and tablets.


How does a PrestaShop implementation differ from WooCommerce?

A PrestaShop implementation differs from WooCommerce mainly in its technology approach, scalability and the range of features available out of the box. PrestaShop is a standalone e-commerce platform built for medium and large stores, with extensive options for managing products, stock and integrations. It works better for more complex projects or higher sales volumes.

WooCommerce, on the other hand, is a WordPress plugin that works very well for smaller and medium stores, especially where content flexibility and simple management matter. It integrates natively with the WordPress blog and CMS, which is a major advantage for content marketing and SEO. The final choice depends on your business goals, the expected scale of the project and the resources available.


How does JustIdea price its e-commerce services?

For performance marketing, SEO and marketing automation, JustIdea prices work based on the scope of activity, the campaign goals and how advanced the required work is. We treat every project individually, taking into account the structure of the ad accounts, how competitive the industry is, the need to expand content and the level of marketing process automation.

Pricing is preceded by a detailed analysis of the starting position, a strategy consultation and, where needed, an audit of the client's current activity. On that basis we recommend a specific model: a fixed monthly retainer, or flexible support based on an agreed schedule of work.


What does updating and developing the store look like over the longer term?

Updating and developing an online store over the longer term rests on ongoing cooperation, results analysis and adjusting the work to changing business needs. At JustIdea we work in stages or on a retainer, which allows flexible planning of feature development, UX and UI work and optimisation.


What does creating the visual identity of an online store look like?

At JustIdea, creating the visual identity of an online store is an integral part of designing a coherent, converting and recognisable brand image. We start with a workshop where we get to know the character of the business, its target audience, brand values and visual inspirations. On that basis we prepare moodboards and style concepts that become the starting point for the design work.

The next step is developing the logo, if one is needed, and the visual identity system, covering colour, typography, iconography style and graphic elements. Together these create a coherent visual language, which we then translate into the store UI: the home page layout, product cards, cart, menu, banners and the other key views.

During design we pay close attention to usability (UX), the mobile version and alignment with the marketing plan. The final identity does not only make the brand stand out visually, it also supports sales and builds customer trust.


What does working with JustIdea on an online store look like?

Working with JustIdea on an online store is comprehensive, transparent and closely aligned with the client's business goals. We divide the whole process into several key stages:

We begin with a workshop where we learn about the business, its target audiences, competitors and sales goals. On that basis we define the project scope and the technology best suited to it, most often PrestaShop or WooCommerce.

Using what we have gathered, we prepare the store structure and UX wireframes, covering buying paths, conversion elements, features and mobile versions. This is the key stage that lets us plan everything that follows precisely.

We design the store UI in line with the brand's visual identity, or create that identity from scratch. We want the visual layer to support sales and set the store apart from its competitors.

Next comes development: front end, back end and every necessary integration (payments, logistics, ERP, CRM and so on). We work in stages, reporting progress in ActiveCollab as we go.

Before launch we run functional and performance testing. Together with the client we verify every element and prepare the store to start selling.

After launch we offer ongoing development support, both technical and marketing (SEO, campaigns, marketing automation). Cooperation can run on a retainer or task by task, depending on your needs.

The whole process runs with a dedicated project team, which keeps the cooperation smooth and the final solution high quality.


What affects the cost of building an online store?

The main factors affecting the cost of building an online store include the chosen technology, the range of required features, the number and complexity of views, and the need to integrate with external systems.


What marketing does JustIdea run for online stores?

Our cooperation covers performance marketing (paid campaigns), SEO and marketing automation implementations, among others.


What e-commerce services does JustIdea offer?

Our cooperation covers building an online store from scratch, running and developing an existing store, performance marketing (paid campaigns), SEO and marketing automation implementations, among others.


Which services support sales growth on foreign markets?

Every service we offer supports sales on foreign markets. What matters most is the right recommendation from the agency, and then matching the scope of cooperation to the client's goals and capabilities.


Which e-commerce platforms does JustIdea work on?

For development work we work primarily on PrestaShop, WordPress and WooCommerce. For our other services we have no technology constraints and can work on any e-commerce platform.
