Historical Context
The concept of keywords emerged with the advent of search engines in the 1990s. Initially, search engines used basic keyword matching to retrieve information. As algorithms evolved, the relevance and significance of keywords have grown, leading to sophisticated techniques in keyword optimization.
Categories of Keywords
Short-Tail Keywords
These are 1-2 word phrases, such as “shoes” or “SEO tools.” They are broad and usually have a high search volume but low conversion rates due to their general nature.
Long-Tail Keywords
These are longer phrases, often 3-5 words, such as “best running shoes for women” or “free SEO tools for small businesses.” They are more specific and typically have lower search volume but higher conversion rates.
LSI (Latent Semantic Indexing) Keywords
These keywords are semantically related to the main keyword, helping search engines understand the context and content of a page better.
