How to Get Notified When a Job Posting Goes Live

Speed matters in job hunting

The best positions fill fast. A desirable role at a well-known company can receive hundreds of applications within the first 24 hours. Many hiring managers stop reviewing applications after the first wave.

If you find out about a posting three days after it goes live, you're already behind. The candidates who applied within the first few hours have a real advantage — their resumes are at the top of the pile.

The problem? Most people discover job postings by manually checking job boards. Maybe you browse LinkedIn once a day, or you check a company's careers page when you remember to. That's unreliable and slow.

What if you got an alert the moment a new posting appeared?

How to monitor job postings automatically

The basic idea: use a website monitoring tool to watch a job board or career page. When the page changes (i.e., a new posting is added or removed), the tool detects the difference and sends you a notification.

This works for:

• Company career pages — most companies list openings on their own website before they appear on aggregators
• LinkedIn job searches — monitor a specific search results page
• Indeed, Glassdoor, AngelList — any job board with a URL
• Government job portals — federal, state, and municipal job sites
• Internal job boards — if your company posts internal roles on an intranet page

The key advantage over job board built-in alerts: you control what to monitor and how often to check. Most job board email alerts are delayed by hours or even days. Direct monitoring catches changes in real time.

Setting up job monitoring with Site Spy

Step 1: Install Site Spy

Get the free extension for Chrome or Firefox.

Step 2: Find the right URL to monitor

This is the most important step. You want a URL that shows exactly the jobs you care about, filtered as narrowly as possible.

For company career pages: Navigate to the company's jobs page and use any filters they provide (location, department, role type). Copy the filtered URL.

For LinkedIn: Run a job search with your target keywords, location, and filters. The URL in your browser bar contains all those filters. Copy it.

For Indeed or other boards: Same approach — filter down to your target search, then copy the URL.

The more specific your URL, the fewer false alerts you'll get. "All jobs at Google" will change constantly. "Software Engineer roles at Google in Berlin" will only change when relevant positions are posted.

Step 3: Add the URL to Site Spy

Click the Site Spy icon, paste the URL, and click Add Watch.

Step 4: Pick the job listings element (recommended)

Career pages have headers, footers, and navigation that can change independently of the job listings. To avoid false alerts, use the element picker to select just the section of the page that contains the job listings.

Click "Pick Element", then click on the container that holds the job listing results. This tells Site Spy to only watch that section and ignore everything else.

Step 5: Set check frequency

• Hourly (free plan) — good for most job searches
• Every 10 minutes (Starter, €4/mo) — ideal for competitive roles that fill fast
• Every minute (Pro, €8/mo) — for time-critical government or contract postings

Step 6: Get notified

When a new job appears (or a listing is removed), Site Spy sends you a notification. Click through to see the visual diff — new listings highlighted in green, removed listings in red.

Strategy: monitoring multiple companies

If you're targeting specific companies, set up a watch for each company's career page. This is more effective than monitoring a single aggregator like LinkedIn, because:

1. Company pages update first. There's always a delay before listings propagate to job boards.
2. Less noise. A company's own career page for your target department might have 5-20 listings, while LinkedIn shows thousands.
3. Filters are stable. Company career page URLs with filters tend to be more stable than LinkedIn search URLs.

Tag each watch by company name so your Site Spy dashboard stays organized.

Strategy: monitoring aggregators effectively

If you prefer monitoring LinkedIn or Indeed, here are tips to reduce false positives:

• Use the tightest filters possible. Job title, location, date posted, experience level — the narrower, the better.
• Pick the results container element. Don't monitor the whole page — sidebar content, login prompts, and ads change constantly.
• Check every 10-30 minutes. Aggregators update more frequently than individual company pages, so faster checks are more useful here.

What the notification looks like

When Site Spy detects a change on a job page, you get:

1. A browser push notification saying the page changed
2. An email (Starter/Pro plans) with a direct link
3. A visual diff showing what was added and removed

The visual diff is particularly useful because you don't just see "something changed" — you see exactly which job listings were added or removed. New listings appear highlighted in green, making them impossible to miss.

Beyond job boards

This same approach works for anything time-sensitive:

• Apartment and rental listings — monitor a filtered Zillow or Craigslist page
• Government permits and licenses — many are posted on websites before any notification is sent
• University course openings — monitor course registration pages for spots
• Event tickets — watch a venue's page for new events or restocks

The common thread: any situation where being first to see a change gives you an advantage.
