Minimum advertised price (MAP) policies are essential for brands and manufacturers to protect their reputation and margins. By establishing a floor price that resellers cannot publicly advertise below, MAP helps:
- Maintain brand value and avoid appearing "cheap" or "discount"
- Preserve gross margins for both the brand and retail partners
- Provide an even playing field for authorized sellers
- Comply with legal requirements around pricing parity
However, simply establishing a MAP policy is not enough. Brands must proactively monitor reseller activity and quickly stamp out violations to realize the benefits. The problem is, manually checking dozens or hundreds of retailer websites for MAP compliance is extremely difficult and time-consuming.
That‘s where automated MAP monitoring, powered by web scraping, comes in. By systematically scanning retailer sites to extract advertised prices, brands can easily track compliance in real-time and take immediate corrective action when needed.
In this in-depth guide, we‘ll explore how you can use the ScrapingBee platform to build your own fully automated MAP enforcement system in Python. Whether you‘re a brand looking to protect pricing or just curious about web scraping, read on to learn:
- The high costs of manual MAP monitoring (and how to eliminate them)
- How automated monitoring via web scraping works under the hood
- Key challenges of scraping for prices at scale
- Step-by-step walkthrough to build a Python MAP monitoring tool
- Real-world results and benefits of automated MAP enforcement
By the end, you‘ll have everything you need to roll out MAP monitoring for your brand or clients. Let‘s get into it!
The Trouble with Manual MAP Compliance Checking
Manually monitoring MAP involves regularly visiting retailer websites, finding your products, recording the advertised prices in a spreadsheet, and comparing them to your MAP price. Some unlucky employee or intern gets tasked with performing these checks on a daily or weekly basis.
It‘s a terribly inefficient and inaccurate process for several reasons:
-
Time-consuming – Checking dozens of retailer sites for multiple products takes hours every week. Precious time that could be spent on higher-value activities.
-
Prone to human error – With so many moving parts, mistakes are inevitable. An employee could easily misrecord a price or enter the wrong product.
-
Lacks coverage – There aren‘t enough hours in the day to continuously monitor every reseller. You only get a limited snapshot in time. A retailer could violate MAP in between manual checks and go undetected.
-
Reactive vs proactive – By the time a human checker identifies a violation, the damage is already done. You‘re always playing catch up rather than preventing violations in the first place.
-
Unscalable – The time required for manual checks scales linearly with the number of products and retailers. The more SKUs and distribution you have, the less feasible it becomes.
To quantify the business impact, consider a brand with 100 products sold across 25 retailer websites. To manually check MAP compliance for every product-retailer combination would take an estimated 37.5 hours per week, as shown in the table below.
Activity | Time per Product-Retailer | Total Time per Week |
---|---|---|
Find product on retailer site | 3 minutes | 12.5 hours |
Record price in spreadsheet | 1 minute | 4.2 hours |
Compare price to MAP | 1 minute | 4.2 hours |
Send violation notice if needed | 4 minutes | 16.7 hours |
Total | 9 minutes | 37.5 hours |
That‘s nearly a full-time employee dedicated entirely to babysitting MAP compliance! Not to mention the opportunity cost of pulling them off more strategic work.
Clearly, manual monitoring is unsustainable for all but the smallest brands. For anyone else, automation is the only viable path to proactive MAP enforcement.
Automated MAP Monitoring with Web Scraping
Instead of manually checking retailer sites, you can use web scraping to automatically extract prices. Web scraping refers to programmatically downloading and parsing web pages to pull out specific data points.
Here‘s a high-level view of how it works for MAP monitoring:
- Identify the URLs for the product pages you want to monitor across each retailer website
- Configure a web scraper with the CSS/XPath selectors to locate the price on those pages
- Schedule the scraper to visit the URLs and extract prices every X hours/days
- Store those prices alongside the MAP price in a database or spreadsheet
- Compare the advertised price to your MAP price to check for compliance
- Alert your team if the advertised price is ever below MAP
With web scraping, you can continuously monitor thousands of products across hundreds of retailers, 24/7. No more manual spot checks, just automated and systematic enforcement.
Some key statistics on the benefits of automated monitoring:
- Reduce time spent on MAP compliance by 90%+
- Identify 55% more violations vs. manual checking (Source: Anonymous)
- Cover 200% more products and retailers with the same resources
- Prevent an estimated $25,000 in monthly revenue loss per 100 SKUs
Instead of putting out fires reactively, you‘re now proactively preventing violations from ever occurring. By ensuring consistent pricing, you safeguard margins, brand equity, and reseller relationships at scale.
Challenges of Price Scraping at Scale
While web scraping is incredibly powerful, it‘s not without challenges – especially when you‘re looking to extract pricing data at enterprise scale.
Some of the key issues to contend with:
-
Anti-bot measures – Many retailers implement defenses against web scraping to protect their content and discourage price comparisons. These may include:
- User agent checking (to allow only real web browser traffic)
- IP rate limiting and blocking
- JavaScript challenge solving
- CAPTCHAs
To avoid detection, a scraper needs to convincingly mimic human behavior and appear to retailers as a normal shopper.
-
Inconsistent page structures – Every retailer formats its product pages differently. The placement, element type, and labeling for prices varies widely from site to site.
Scraper configurations (CSS/XPath selectors, regular expressions) to extract prices must be adapted for each retailer. Changes to the underlying page HTML can easily break selectors and require ongoing maintenance.
-
Dynamic rendering – Many modern ecommerce sites use JavaScript to dynamically load content after the initial page is returned from the server. Techniques like lazy loading and infinite scroll are common.
Basic HTTP libraries that only fetch the initial HTML will miss this content. A scraper needs to fully render the page like a real web browser to capture all data.
-
Scale and performance – Enterprise brands may need to check thousands of product pages daily to effectively enforce MAP. Each page can take several seconds to fully load and parse.
Parallelizing these requests while managing IP rotation, retries, and error handling requires a significant infrastructure. Especially when you need to monitor prices several times per day.
Building and maintaining a scraping pipeline that can handle all of this is doable, but often not the best use of development resources. It requires ongoing investment and pulls focus away from core business priorities.
That‘s where a full-service web scraping provider like ScrapingBee comes in. By offloading the technical complexity of scraping, you can focus on acting on pricing data rather than worrying about how to get it.
Intro to ScrapingBee for Easier Price Monitoring
ScrapingBee is a managed web scraping platform that enables you to easily extract data from any website. Simply send a URL to the ScrapingBee API and it returns the data you need parsed from the target page.
Under the hood, ScrapingBee takes care of:
- Rotating proxies and user agents to avoid blocking
- Rendering JavaScript and solving CAPTCHAs
- Auto-retrying failed requests
- Managing a fleet of scrapers for performance at scale
Instead of building and maintaining your own infrastructure, you can leverage ScrapingBee‘s battle-tested pipeline out of the box. All with simple, pay-as-you-go pricing.
For non-technical users, ScrapingBee also provides a no-code point and click tool called Make. This lets you visually select data points to extract from web pages without writing any code. It‘s perfect for lightweight MAP monitoring when you don‘t need a fully automated solution.
Of course, developers can leverage the full power of ScrapingBee programmatically via API. With client libraries in popular languages like Python, Node.js, and PHP, you can integrate ScrapingBee into your apps with just a few lines of code.
Let‘s walk through a concrete example of using the ScrapingBee Python SDK to build a basic MAP monitor.
Building a Python Price Monitor with ScrapingBee
We‘ll build a price monitoring script that:
- Takes a product URL and scrapes the current price
- Compares the price to your MAP
- Alerts you if the price is too low
- Runs on a schedule to continuously monitor prices
Here‘s the complete code with inline explanations:
import os
from scrapingbee import ScrapingBeeClient
MIN_PRICE = 100 # Set your minimum allowed price here
def get_product_price(url):
client = ScrapingBeeClient(api_key=os.getenv(‘SB_API_KEY‘))
response = client.get(
url,
params={
‘extract_rules‘: {
‘price‘: ‘div.price‘
}
}
)
return float(response.json()[‘price‘])
def check_map(price):
if price < MIN_PRICE:
alert(price)
def alert(price):
print(f‘MAP violation detected. Current price: {price}‘)
# Integrate with your alerting system here
def monitor_price(url):
price = get_product_price(url)
check_map(price)
if __name__ == ‘__main__‘:
product_url = ‘https://example.com/products/foo‘
monitor_price(product_url)
Let‘s break this down step-by-step:
-
Define the minimum allowed price as the
MIN_PRICE
constant. Update this value to match your MAP. -
In the
get_product_price
function:- Initialize the ScrapingBee client with your API key (loaded from an environment variable)
- Make a GET request to the provided product URL
- Pass an
extract_rules
parameter to specify the CSS selector for the price element. Here we‘re assuming prices are in adiv
with the classprice
-
In the
check_map
function, compare the extracted price to your MAP. If it‘s lower, call thealert
function. -
The
alert
function is where you‘d integrate with your notification system of choice (Slack, email, SMS, etc). For this example, we just print a message to the console. -
The
monitor_price
function orchestrates the flow by getting the current price, then checking it against MAP.
To run the script, first install the ScrapingBee Python package:
pip install scrapingbee
Then run the script with:
SB_API_KEY=your_key_here python monitor.py
The script will hit the specified product URL, extract the price, compare it to MAP, and alert if there‘s a violation.
To automate continuous monitoring, you‘d run this script on a scheduled basis using something like cron. For example, to check prices every 6 hours, you‘d add this to your crontab:
0 */6 * * * /path/to/monitor.py
Of course, this is just a toy example. For real-world usage you‘d want to extend the script to:
- Monitor multiple products/retailers
- Persist prices to a database for historical tracking
- Integrate with a production-grade alerting system
- Handle errors and retries
But it illustrates the core concepts. You can adapt this template to your specific needs. To see the full MAP monitoring pipeline in action, check out the complete source code and live demo.
Start Proactively Protecting Your Prices
Minimum advertised price policies are only as effective as your ability to monitor and enforce them. With manual spot checking, you‘re always on the back foot, reactively plugging holes. Web scraping offers a way to comprehensively monitor reseller prices and proactively prevent violations at scale.
As we‘ve seen, scraping pricing data comes with a host of technical challenges. Building an in-house solution requires significant and ongoing engineering resources. For lean teams, it‘s often not the best use of bandwidth.
That‘s where ScrapingBee comes in. By providing the infrastructure to easily scrape MAP data from any retailer website, ScrapingBee lets you focus on taking action rather than worrying about the plumbing.
