Learn About Web Optimization

Jump to the glossary

A knowledge base about how meaning is structured, moved, encountered, retrieved, maintained, and cared for across web systems.

After becoming familiar with these optimization concepts, and implementing even a few of them, you should see some difference in your website visibility.

Planning Topic Clusters for User Experience

Planning Topic Clusters for User Experience

A topic cluster is a group of related pages connected through internal links and organized around a broader central subject. In website optimization topic clusters are often discussed as a way to help search engines understand topical depth. That is true, but it is...

Accessible Dialogs: Focus, Context, Escape, and Return

A modal dialog temporarily changes the boundary of an interface. It asks someone to pause the surrounding page and complete a focused task or decision. If the implementation only draws a box over the page, different users may remain in different contexts: some inside...

Hybrid Retrieval: How Keyword and Vector Search Work Together

Hybrid Retrieval: How Keyword and Vector Search Work Together

Hybrid retrieval combines lexical search, which pays close attention to words and terms, with semantic or vector search, which looks for similarity in meaning. Each method reveals a different part of a corpus. Used together, they can retrieve candidates that either...

What Is Vector Similarity?

What Is Vector Similarity?

Vector similarity is a way to estimate how closely two numerical representations resemble one another. In search and AI systems, those numerical representations often encode text, images, audio, products, users, or other entities as vectors. When two vectors are near...

Cosine Similarity: How It Works and How to Interpret the Score

Cosine Similarity: How It Works and How to Interpret the Score

Cosine similarity measures how closely two nonzero vectors point in the same direction. It compares their orientation rather than their length, producing a score between −1 and 1. In text retrieval, those vectors often represent a search query and a passage of text....
