Average Click Position
When a user selects a search-result item and clicks on it, what was the position of the item in the list? Look for Average Click Position under the Relevance menu on the left side of the SearchStax dashboard.
Average Click Position is a good gauge of the effectiveness of the search results. Low numbers (below 5 or so) mean that the users found the desired items near the top of the search results. Higher numbers indicate that the search was successful, but the user had to scroll down through the search results to find the desired items.
In general, the lower the number the better. Over time you would like to see the Average Click Position trend down.
The data table below the graph lets us dig for more information. It can be filtered by a keyword or by setting a numeric limit on Average Click Position, Clicks, or Search Volume. It can be sorted up or down on any one of the columns.
Mean Reciprocal Rank (MRR) is a weighted average of click-through positions resulting in a value between zero and one. Higher values indicate that the "right answer" was often near the top of the search results. Look for MRR under the Relevance menu on the left side of the SearchStax dashboard.
MRR gives us feedback on the quality of our search experience. It helps us tune the system. For instance, did the recent changes in the synonym list improve the search experience? If so, then the MRR value should have risen. An upward trend in the MMR value over time indicates that the search is becoming more focused on the needs of the users.
The Similar Searches display gathers similar user queries in order to identify patterns in user behavior when discovering a particular result. Look for Similar Searches under the Relevance menu on the left side of the SearchStax dashboard.
This display is a powerful tool to improve the search experience for your users. It shows user queries that led to specific results. This lets the team optimize search relevance algorithms and extend the set of synonyms.
