Combine social trend signals and price trackers to get alerts only when a product is trending and at your target price. Build it in hours.

Promo codes that don’t work, scattered deal posts across TikTok and Reddit, and frantic last-minute searches are why shoppers waste time and money. This guide shows, step-by-step, how to build an automated deal alert system that combines social signal monitoring with proven price trackers so you only get alerted when a product is both trending and at a target price.

Why this matters in 2026

In late 2025–early 2026, discoverability shifted: audiences form preferences on social platforms before they ever search on Google. As Search Engine Land observed in January 2026, brands and products show up across social, search, and AI-powered answers — and the same dynamics apply to deals. A trending product on TikTok or Reddit will drive scarcity and price drops; if you can catch that signal and pair it with a price trigger, you win the best deals without manual slog.

“Audiences form preferences before they search. Discoverability is no longer about ranking first on a single platform.” — Search Engine Land, Jan 16, 2026

Quick summary — what you’ll build

A reliable price alert for a specific product SKU across retailers (Keepa/CamelCamelCamel or store API).
A social signal monitor that tracks mentions, engagement spikes and video trends on TikTok, Reddit, X/Twitter, and YouTube.
An automation workflow (Zapier/Make/Huginn) that only notifies you when social momentum AND price target are met.
Delivery channels: push notification, Telegram, SMS, or browser extension alert with one-click buy link and coupon checks.

Before you start — tools checklist

Pick tools that fit your comfort level. You can build a full no-code pipeline or use open-source components for maximum control.

Price trackers: Keepa (Amazon), CamelCamelCamel, Slickdeals price trackers, store-specific APIs (Best Buy, Walmart, Target).
Social monitoring: Talkwalker, Brand24, Mention, Reddit RSS/Pushshift, TikTok trend scrapers (third-party RSS solutions), YouTube RSS, X/Twitter API or TweetDeck for lightweight monitoring.
Automation platform: Zapier, Make (Integromat), IFTTT, or Huginn for self-hosted automation.
Notification channels: Telegram bot, Pushover, Pushbullet, Twilio (SMS), or browser push via OneSignal.
Extras: Browser extension (Honey, RetailMeNot), cashback/coupon checkers, and an AI summarizer (OpenAI/GPT or locally hosted LLM) to reduce noise.

Step-by-step: Build the automated deal alert

Step 1 — Define the product & your price target

This is simple but crucial: specify the exact SKU or product URL and your target price. Use full SKUs or ASINs for accuracy (e.g., Nintendo Switch OLED, ASIN B08XXXX). Decide whether your trigger is a flat price (e.g., $249) or percentage drop (e.g., 25% off market median).

Pro tip: store multiple price targets — “buy now” and “watch” thresholds.
Pro tip: set region/currency to avoid false triggers from international listings.

Step 2 — Set up reliable price tracking

Use Keepa or CamelCamelCamel for Amazon; use store APIs or price aggregator extensions for non-Amazon retailers. Choose polling cadence that balances speed and cost — real-time is ideal for flash deals but may cost more.

Create an account with your chosen price tracker and add the product URL or ASIN.
Set the target price and desired alert channel (email, webhook, RSS).
If the tracker supports webhooks (Keepa Enterprise or store APIs), connect it to your automation platform to receive immediate events.

Example: Keepa webhook triggers when Amazon price <= $249. Use Keepa’s price history to set realistic thresholds.

Social signals filter noise: you only want alerts when a product is trending. Track three signal types:

Mention volume (how often the product is mentioned in a timeframe).
Engagement velocity (likes/comments/shares per hour — indicates virality).
Top-creator posts (posts from high-followers accounts that can spur mass demand).

How to capture those signals:

TikTok: use a third-party trend scraper or a social-monitoring tool that offers TikTok listening. Create a keyword list (product name, nicknames, model numbers, hashtag variations).
Reddit: subscribe to product- or category-focused subreddits and use subreddit RSS or Pushshift-based queries for phrase matches and upvote velocity.
X/Twitter & YouTube: use API filters for mentions and engagement spikes. For YouTube, monitor new uploads with product mentions and view growth over 24–72 hours.
Forums and Discord: where relevant, use webhook integrations or bots to notify you of surges in mention counts.

Signal thresholds: set what “trending” means (e.g., >200 mentions in 24 hours, or >500% engagement growth hour-over-hour). Start conservative and tune after 2–4 weeks.

Step 4 — Combine signals in an automation workflow

This is where deal automation gets powerful. Use a platform like Zapier/Make for no-code, or Huginn for a self-hosted, privacy-friendly flow.

Create two triggers: one for price events (price <= target) and one for social events (signal threshold met).
Use a conditional step: only proceed to notify if both triggers occurred within a set window (e.g., 24–72 hours). This prevents alerts for a price drop that happened months ago or a social spike without a discount.
Enrich the notification with: current price, price history chart link, top social post links, coupon suggestions, and a one-click purchase link.

Example workflow: Keepa webhook → Webhook catch in Make → Check timestamp and price → Query Brand24 API for mention volume → If volume > threshold and price <= target → Send Telegram message with buy link and coupon check.

Step 5 — Notification design: make alerts actionable

When a deal alert hits your inbox or phone, you should be able to act immediately. Include:

Product name, retailer, current price, and “was” price.
Direct purchase link with affiliate tracking (if you use affiliates).
Top 1–3 social posts that caused the spike (helps judge legitimacy).
Coupon check results and cashback options (e.g., 5% at Rakuten).
Expiration estimate and “buy now” vs “watch” recommendation.

Step 6 — Add reliability & anti-noise rules

To avoid false positives and spammy alerts, add validation steps.

Duplicate suppression: block repeat alerts for the same SKU within a chosen window (e.g., 24 hours).
Coupon validation: automatically test popular coupon codes through a lightweight API or a headless browser check before recommending.
List filtering: ignore posts from known resellers or suspicious accounts to reduce pump-and-dump noise.
Rate limits: batch social queries and cache results to avoid hitting API limits and incurring costs.

Advanced options for power users

Use AI to reduce noise and surface quality

In 2026, lightweight AI summarizers are fast and cheap. Use an LLM step to summarize top social posts and classify them as “credible,” “user review,” or “promo.” This helps you decide whether to buy or wait.

Multi-source price consensus

Rather than relying on a single retailer, fetch prices from multiple stores and compute a consensus or lowest price. This is critical for electronics and trending toys where third-party sellers create price confusion.

Cashback & stacking rules

Automate a final check for stacking opportunities: site coupons, credit card offers, and cashback portals. If a 5% cashback + 10% coupon is available, include that in the alert so you know the real effective price.

Real-world example (case study)

Here’s a compact case so you can replicate the logic:

Product: Noise-cancelling earbuds (Model XYZ, SKU 12345)
Target price: $79 (market median $129)
Social signal threshold: 300 mentions across TikTok + Reddit + X in 24 hours or a 400% engagement lift on a single TikTok post.
Workflow: Keepa webhook + Brand24 mention feed → Make filters for age & velocity → On match, Make queries Best Buy and Walmart APIs for current price → If any price <= $79 and social threshold met → Send Telegram alert with buy link, coupon checks, and top 2 social links.

Outcome: In testing across Black Friday-style drops, this pipeline flagged 8/10 high-quality deals and suppressed 15 false positives that were price drops without social momentum.

Troubleshooting & common pitfalls

Too many alerts: raise social thresholds, add duplicate suppression, or convert some alerts to a daily digest.
No alerts at all: check API keys, verify webhooks, and ensure polling cadence is adequate. Test with a deliberately low price target to validate flow.
Expired coupon recommendations: add an on-demand coupon validation step before notifying about a coupon.
API rate limits/costs: cache responses, reduce polling frequency, and prefer webhooks when available.

Privacy, ethics, and reliability in 2026

By 2026, platforms tightened access to some social APIs and improved privacy measures. Best practices:

Prefer tools that respect platform TOS and use official APIs when possible.
When scraping or using third-party scrapers, throttle requests and cache aggressively to avoid IP bans.
Label alerts transparently: show timestamped evidence so you can audit why a deal was flagged.

Optimizing for sustained savings

Treat your alert system like a living product. Tune it monthly:

Refine social keyword lists as new slang or model nicknames emerge.
Adjust price thresholds using historical price data — set “smart” thresholds at historical low percentiles.
Expand or pare down sources based on ROI: if a network yields low-quality alerts, drop it.

Final checklist before you go live

Confirm the product SKU and region settings.
Verify price tracker webhook or polling is active and accurate.
Validate social monitors return expected sample matches.
Run a full end-to-end test with a temporary low-price trigger and confirm notification arrives complete with links and coupon checks.
Set duplicate suppression and quiet hours so you don’t get woken at 3 AM for minor fluctuations.

Key takeaways

Combine signals: price triggers alone create noise; social momentum alone creates FOMO. Together they give high-confidence alerts.
Automate smartly: use webhooks and conditional logic to avoid missed opportunities and false alarms.
Use AI selectively: summarize and classify social posts to speed decision-making without overpaying for monitoring.
Keep tuning: social slang, creator impact, and retailer behavior change fast — review your rules monthly.

Next steps — a minimal plan you can implement in one afternoon

Create accounts: Keepa (or equivalent) + Brand24 (or free Reddit RSS + X filters) + Zapier/Make + Telegram.
Add one product, set a target price, and configure a Keepa webhook or daily email alert.
Set up a Brand24/Reddit/X search for that product and a simple Zap that sends a test notification on a high mention count.
Connect the two in Zapier/Make with a conditional: notify only when both price and social triggers occur within 48 hours.
Test, tweak, and expand to more products once the initial setup proves reliable.
