Methods and tools
Automated competitive intelligence: methods and tools
Automating competitive monitoring means handing four tasks to machines: collecting, matching, analyzing and alerting. Tools do not handle them all equally well. Here is how to compare approaches before you choose.
Key points
- Automated monitoring chains four steps: collection, product matching, analysis, alerting.
- Matching is the hardest and most decisive step, especially without EAN codes.
- Tools range from in-house scripts and ad platform reports to general software, enterprise suites and sector-specific tools.
- Choose on a written grid, and test on your own products before signing.
The four steps of automated monitoring
- Collection: reading competitors' pages regularly, with their prices, promotions, stock and delivery fees.
- Matching: linking each of your products to its equivalents elsewhere. Without this step, you collect data you cannot compare.
- Analysis: price position by family, gaps, history, new products.
- Alerting and action: telling the right person at the right time, or even adjusting a price according to rules.
The market differs most on the second step. Collection is a known technical problem; matching two products that share neither a name nor a code takes recognition methods based on attributes, text and images.
The possible approaches
Spreadsheets and manual readings
This is where many teams start. Free and flexible, it does not scale beyond a few dozen products and only keeps a history if someone maintains it rigorously.
In-house scripts
A developer can write robots that read competitor sites. This gives full control, but every redesign of a site breaks the robot, and product matching still has to be built. It also requires rules of conduct: follow each site's robots.txt file[5] and keep the load on their servers low.
Ad platform reports
Google Merchant Center compares your prices with a benchmark computed from other merchants selling the same product[4]. It is free for advertisers, but limited to products that share an identifier, and blind to competitors who are not on Google Shopping.
Monitoring software
The range is wide. Comparison guides separate general tools with accessible plans, such as Prisync, based in Turkey, from enterprise suites such as Minderest in Spain[1]. In France, NetRivals, acquired by Lengow, combines monitoring and marketplace repricing[2], and Paarly, based in Toulouse, offers matching validated by its experts[3]. Most of them work on quotes.
Sector-specific tools
Some sectors have constraints of their own. In furniture, EAN codes are missing, products are recognized by eye and dimensions matter. A tool built for the sector carries its criteria: seats, sofa bed, corner orientation, legs, size tolerance.
The selection grid
Write your criteria down before you see any demo. These matter most.
| Criterion | The question to ask |
|---|---|
| Matching without EAN | How does the tool link two products with no shared code? By photo? With what validation? |
| Coverage | Which retailers and marketplaces are read today, and in which countries? |
| Frequency | Daily? Several times a day? For the whole catalog or part of it? |
| Delivered price | Are delivery fees collected? |
| History | How many months are kept, promotions included? |
| Alerts | By email, in the tool, with which thresholds? |
| Action | Is repricing possible? On your store, on marketplaces? With which safeguards? |
| Integration | API, exports, formats? |
| Data | Where is it hosted? Who can access it? |
| Price | Public pricing or quote? Commitment? |
| Onboarding | How many days before the first useful results? |
Test before you sign
A demo on products chosen by the vendor proves little. Ask for a test on five to ten of your own best sellers, including at least one private-label product with no published EAN. Look at three things:
- how many relevant equivalents the tool finds;
- how many false friends it suggests, and whether it says so;
- how long it takes.
The rules to respect
Automated monitoring reads public information, but it is still regulated. Beyond robots.txt, the European Union protects databases that required substantial investment against the extraction or reuse of a substantial part of their contents[6]. Monitoring should inform your decisions, not republish a competitor's catalog. It does not need personal data either: prices, photos and specifications are enough.
