Forecasting Methodology

How we generate accurate, transparent search traffic forecasts

What This Tool Does

PredictClicks analyzes your historical search traffic to project where your clicks and impressions are heading. It answers: "Based on my current trajectory, what should I expect next month/quarter?" We use the same forecasting technology trusted by Meta, Uber, and other data-driven companies - but you don't need to be a data scientist. Connect your Search Console, choose a time horizon, and get your forecast with confidence ranges. Perfect for: • Getting stakeholder buy-in on SEO investments • Setting realistic traffic goals • Measuring the impact of changes (before/after) • Planning content calendars and budgets

How It Works

Step 1: We Pull Your Data Connect your Google Search Console or Bing Webmaster Tools. We fetch up to 16 months of historical traffic data - clicks, impressions, and patterns. Step 2: Pattern Detection Our engine analyzes your data to find trends (going up, down, or flat), weekly patterns (which days perform best), and seasonal variations (holiday peaks, summer dips). Step 3: Forward Projection Using these patterns, we project your traffic forward for your chosen horizon (1-12 months) with confidence ranges showing best and worst case scenarios. Data Freshness: Google Search Console has a 3-day delay before data is complete. We automatically exclude the most recent 3 days to ensure accurate forecasts.

Data Requirements

The more historical data available, the more reliable your forecast. Minimum requirements vary by how far ahead you want to predict:

More historical data generally improves forecast accuracy and stability. GSC provides up to 16 months (479 days) of data.

Confidence Intervals

Every forecast shows a shaded range around the projected line. This is your confidence interval - the zone where actual traffic is likely to fall.

90% Confidence

The shaded area shows the range where actual values are 90% likely to fall. Wider bands = more uncertainty about the future.

How to Use Confidence Bounds

90% Confidence: There's a 90% chance actual results fall within the shaded range. Reading the Range:Upper Bound - Optimistic scenario. Useful for setting stretch goals. • Center Line - Most likely outcome based on current trends. • Lower Bound - Conservative scenario. Use this for budget planning. Why Ranges Vary: • Further into the future = wider ranges (more uncertainty) • Volatile traffic history = wider ranges • Stable, predictable patterns = narrower ranges Pro Tip: When reporting to stakeholders, present the range rather than a single number. It builds trust and sets realistic expectations.

Accuracy Metrics

Each forecast includes a Confidence Score so you know how reliable it is. We convert the technical MAPE (Mean Absolute Percentage Error) into a simple 0-100% score where higher is better. A score of 85% means forecasts are typically within 15% of actual values:

Forecast Horizons

Choose how far ahead to forecast based on your planning needs:

Shorter forecast horizons produce more reliable predictions. Use 1-3 months for actionable planning.

Display Views

Forecasts can be viewed at three levels: Weekly: 7-day totals (Monday to Sunday). Best for short-term monitoring and detecting patterns. Monthly: Calendar month totals. Ideal for monthly reporting and comparing month-over-month performance. Quarterly: Three-month totals (Q1: Jan-Mar, Q2: Apr-Jun, etc.). Best for strategic planning and year-over-year comparisons. Partial Periods: When a forecast doesn't cover a complete period, we pro-rate the values so you can fairly compare them. Partial periods are clearly marked.

Limitations

What Forecasts DO: • Project current trends and patterns forward • Quantify uncertainty with confidence ranges • Detect and incorporate seasonal patterns • Identify when trends have shifted What Forecasts DON'T: • Predict unprecedented events (algorithm updates, viral content, market crashes) • Account for SEO changes you haven't implemented yet • Guarantee specific outcomes This is a projection tool, not a crystal ball. Forecasts show where you're heading if current trends continue - they don't predict the unpredictable.

When to Update

Run a new forecast: • Monthly, to track how projections evolve • After major Google algorithm updates • After significant site changes (migrations, redesigns) • When launching major content campaigns Compare before/after: Run a forecast before making changes, implement your strategy, wait 2-4 weeks for data, then compare actual results to what was projected. The difference shows your impact.
