GLOSSARY

Absolute Boosting

Absolute boosting is a ranking strategy in search and recommendation systems that pushes specific items or categories to the top of results, regardless of their natural relevance score.

It is often used in e-commerce search to promote high-margin products, seasonal campaigns, or business-priority items.

What is Absolute Boosting?

In most search engines, results are ordered based on relevance, which is calculated from query–document matching, popularity, or personalization.

With absolute boosting, a product, brand, or category can be manually elevated above algorithmic relevance. This ensures visibility for items the business wants to prioritize, even if they are not the most relevant according to standard ranking logic.

For example, an online store can use absolute boosting to display new arrivals or featured deals at the top of search results.

How Does Absolute Boosting Work?

Business Rules

Merchants define rules, such as:

  • Always display Brand X in the first 3 positions
  • Push Black Friday offers above all organic results

Overrides Natural Scoring

The boosted items bypass the usual ranking algorithms and are inserted at fixed positions or with higher weight.

Integration with Search Engines

Absolute boosting is implemented in many site search and recommendation platforms, often via admin panels or APIs that allow merchandisers to configure promotional logic.

Examples in E-commerce Search

  • Promoting high-margin products: A retailer boosts products with the best profit margins to increase revenue.
  • Seasonal campaigns: During Christmas, boosted gift collections appear first.
  • Brand prioritization: An online shop highlights its private label brand by boosting it above competitors.
  • Clearance sales: Boosting discounted items helps reduce excess stock.
