How to Calculate Average Position

What is Average Position?

The average position (AP) is the mean rank of your website's search results across multiple queries. It provides a single number that represents how high your pages typically appear in search engine results pages (SERPs).

This metric is particularly useful for evaluating the effectiveness of your SEO efforts. A lower average position indicates better visibility in search results, which generally correlates with higher click-through rates and better organic traffic.

How to Calculate Average Position

Calculating average position involves several steps:

1. Identify the search queries you want to analyze
2. Determine the position of your website for each query
3. Calculate the average of these positions
4. Adjust for any weighting factors (like click-through probability)

For most practical purposes, you can calculate a simple arithmetic mean of your positions across multiple queries. However, search engines use more sophisticated methods that account for factors like the probability that users will click on each result.

The Formula

The basic formula for calculating average position is:

Where:

• Position is the rank of your website in search results (1 for first position, 2 for second, etc.)
• Click Probability is the likelihood that users will click on that position

For a simplified calculation without click probability weighting, you can use:

Worked Example

Let's calculate the average position for a website that appears in the following positions for 5 different search queries:

Using the simplified formula:

So the average position is 3, meaning your website typically appears in the third position across these queries.

Interpreting Results

Interpreting your average position requires understanding what constitutes a good position for your industry. Generally:

• Positions 1-3 are considered excellent
• Positions 4-10 are good
• Positions 11-20 are acceptable
• Positions below 20 may indicate room for improvement

Remember that average position is just one metric. You should also consider other factors like click-through rate, dwell time, and conversion rates to get a complete picture of your search performance.
