It all started from using backlinks to rank sites and use it as a measurement for the quality and authority of the sites. So earlier the basic pattern was to stuff keywords and get backlinks to rank. This method was then started to get misused by the blackhat seo users. Using softwares to blast backlinks through commenting and forum posting. So, Google introduced many Algorithms like Hummingbird, Panda etc to tackle these blackhat seo guys. Now, lets dive in the details of the semantic search first.

What is Semantic Search?

The dictionary meaning of "Semantic" is "relating to meaning in language or logic". So, in search engine terms semantic relates to the contextual meaning of a search term. If a search engine is able to understand the meaning of the search term then it can give you more accurate and informative results. Basically semantic search matches the concept, synonyms, uses natural language algoritms to generate a better structured search results. It actually is able to understand the intent of user's search term. You can say it is a sort of Artificial Intelligence (AI).


Latent Semantic Indexing (LSI)

Latent Semantic Indexing (LSI) is basically a mathematical method which is used to ascertain relationship between search terms and their conceptual meanings. LSI is nowadays extensively used by Google bots in their ranking algorithms. When a bot crawls your web page, it checks for the target keywords (one that appears in title, meta description, headings and paragraphs) and their semantic words or phrases. It then defines the keywords of the page to rank for.

So, if your page title is "Top 10 Laptops" then it will also look for words like notebooks, ultrabooks, processor, screen size, laptop company names and models, RAM, hard disk etc. It will look for synonyms as well as the things related to it.
