How to schedule recurring web scrapes with Zenrows for up to date business intelligence

If you’re tired of manual copy-paste or wrestling with one-off scripts to keep your business data fresh, this is for you. Maybe you’re tracking competitor prices, monitoring product listings, or keeping an eye on public sentiment. Whatever the case, scraping the web once is easy—but automating it so you always have up-to-date info? That’s where most folks trip up.

We’ll walk through how to set up reliable, recurring web scrapes using Zenrows, a tool that handles a lot of the annoying stuff for you. I’ll show you what works, what’s worth skipping, and how to avoid getting stuck.

Why recurring scrapes actually matter

Here’s the truth: business intelligence is only as good as its data. If your info is stale, you’re making decisions on last month’s news. Recurring web scrapes let you:

  • Spot trends as they happen—not weeks later.
  • React to changes in pricing, inventory, or reviews faster than competitors.
  • Cut down on manual grunt work (no more late-night spreadsheet wrangling).

But it’s easy to overcomplicate things. You don’t need a PhD in computer science or a team of engineers. You just need something that works, runs on schedule, and doesn’t fall apart when a website gets fussy.

Step 1: Figure out what and how often to scrape

Before you write a line of code or sign up for anything, get specific:

  • Which sites or pages matter? Don’t try to boil the ocean. Start with one or two high-value targets.
  • What data do you need? Product names? Prices? Stock status? Be picky.
  • How fresh does the data need to be? For most business use-cases, daily or hourly is enough. Don’t schedule every 5 minutes unless you need it (you’ll just annoy everyone and probably run into limits).

Pro tip: Write out your target URLs, what data you want, and how often you’ll scrape it. This saves hours of backtracking later.

Step 2: Set up Zenrows and your first scrape

Zenrows is a web scraping API that handles a bunch of headaches for you—like rotating proxies, CAPTCHAs, and browser spoofing. In plain English: it helps you get the data you want with less hassle.

Here’s how to get going:

  1. Sign up for Zenrows.
  2. Free trials are available, so you can test before paying.
  3. Get your API key.
  4. You’ll need this for authentication.
  5. Read the docs.
  6. Don’t skip this. The API is straightforward, but little details (like request limits and response formats) matter.

Example: Fetching a product page

Let’s say you want to pull the price from an e-commerce page. With Zenrows, you’d use a URL like: bash curl "https://api.zenrows.com/v1/?apikey=YOUR_API_KEY&url=https://example.com/product123"

You’ll get back the full HTML of the page. From there, you can extract whatever you need—prices, titles, etc.

What works:
- Zenrows does the heavy lifting on anti-bot stuff. You won’t get blocked as easily as with raw requests. - It’s API-first, so you can use any language or tool you like.

What to ignore:
- Don’t overthink “headless browser” options unless you’re scraping sites that really require it (like heavy JavaScript pages). Start simple.

Step 3: Extract the data you actually care about

Getting the HTML is half the battle. Now you need to pull out the bits that matter.

  • Use a parser: Python’s BeautifulSoup, JavaScript’s cheerio, or even Zenrows' built-in extraction features.
  • Target by CSS selectors: Find the element that holds your price, title, or whatever. CSS selectors (like .product-price or #main-title) are your friends.

Example in Python: python import requests from bs4 import BeautifulSoup

url = "https://api.zenrows.com/v1/?apikey=YOUR_API_KEY&url=https://example.com/product123" resp = requests.get(url) soup = BeautifulSoup(resp.text, 'html.parser') price = soup.select_one('.product-price').text print(price)

Pro tip:
Test your selectors in your browser’s dev tools first. Saves a ton of headaches.

What doesn’t work:
- Trying to extract everything. Focus on the few fields you need—less to break when sites change.

Step 4: Automate it—don’t sit there hitting “run” all day

This is where most people get stuck. Running your script once is easy. Getting it to run every day (or hour) without you thinking about it? That’s the goal.

Option 1: Use your own computer (not recommended for business use) - You can use cron jobs (Mac/Linux) or Task Scheduler (Windows) to run your script on a schedule. - Downsides: If your computer’s off, nothing runs. Not scalable.

Option 2: Use a cloud scheduler (the better way) - Cloud automation tools like GitHub Actions, AWS Lambda, or Google Cloud Functions can run scripts on a schedule—no server needed. - Trigger your scraping script at whatever interval you set.

Example: Using GitHub Actions

Here’s a super-basic workflow file (.github/workflows/scrape.yml):

yaml name: Scheduled Scrape on: schedule: - cron: '0 7 * * *' # every day at 7am UTC jobs: scrape: runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 - name: Run scraping script run: python scrape.py

Now your script runs daily, even if your laptop’s asleep.

Pro tip:
Store your API key as a secret in your GitHub repo—don’t hardcode it.

What works:
- GitHub Actions is free for small jobs and easy to set up. Great for prototyping. - Cloud schedulers keep running, even if you forget about them.

What to ignore:
- Don’t build your own scheduler unless you really need to. Use what’s out there.

Step 5: Store or send the data somewhere useful

Scraped data sitting in a log file isn’t helpful. Decide where you want it:

  • Spreadsheets: Save as CSV and upload to Google Sheets or Excel.
  • Databases: For more complex needs, push into PostgreSQL, MySQL, or a cloud database.
  • Alerts: Email, Slack, or SMS if you want real-time heads-up when something changes.

Example: Saving to CSV in Python

python import csv

with open('prices.csv', 'a', newline='') as f: writer = csv.writer(f) writer.writerow([product_name, price, scrape_time])

Pro tip:
Start simple. Don’t build an entire data warehouse if all you need is a daily spreadsheet.

Step 6: Handle errors and avoid getting blocked

Web scraping is brittle. Sites change layouts, add CAPTCHAs, or block IPs. Here’s how to stay afloat:

  • Zenrows helps a lot with anti-bot stuff, but nothing’s perfect. If you see weird results or missing data, check if the page layout changed.
  • Retry failed scrapes with a backoff (wait a few minutes, then try again).
  • Respect robots.txt and site terms. Don’t be “that guy” who scrapes every 5 seconds.

What works:
- Monitoring your results. If your spreadsheet is suddenly empty, you’ll want to know before your boss does. - Logging all errors, so you can fix things fast.

What doesn’t work:
- Ignoring failures and hoping no one notices. They will.

Step 7: Monitor, tweak, and stay sane

No recurring scrape is set-and-forget. Sites change, your needs shift, stuff breaks.

  • Set up basic monitoring: Even a daily email with “scrape succeeded!” is better than silence.
  • Revisit your selectors: If the site updates, your code needs to keep up.
  • Don’t overcomplicate: More moving parts = more headaches. Keep your stack simple.

Wrapping up

Automating web scrapes with Zenrows isn’t magic, but it is doable—even if you’re not a pro developer. Figure out what matters, start small, and use the simplest tools that work. Most of the headache is in scheduling and keeping things running, not in the scraping itself.

Keep it simple. Get something basic working, then improve it as you go. That’s how you actually get value—and stay ahead of the folks still doing things by hand.
