SEO terminology (LSI , Keyword stemming )

Latent Semantic Indexing (LSI) It is a data retrieval technique which finds connection between words and the use of synonyms while fetching data from the index.

Keyword stemming is the practice to find out root word from search query. For instance, a keyword like “playful” will be split to the word “play” by stemming algorithm that turns it possible. Thus, the search result appear on the screen will contain the word “play” in it.

Florida update happened on November 16th 2003. This update applied stemming, maintained local rank, penalized over optimized sites by applying filter etc. In short, it modified the search results before presenting it to the user by applying filters.

PR is Page Rank which is defined by quality inbound links from other website or web-pages to a web page or website as well as say the importance of that site.
SERP stands for Search Engine Result Page is the placement of the website or web-page which is returned by search engine after a search query or attribute.

RSS stands for Really Simple Syndication is useful to frequently publish all updated works including news headlines, blog entries etc. This RSS document also known as web feed, feed or channel that incorporate summarized text including metadata i.e. authorship and publishing dates etc.

Sand Box:
The term Sandbox refers to the place where Google puts new websites when they first get released. 
This is done in order to ensure that the website is relevant to the particular search terms it refers to and this helps removing thousands of spammy websites before they appear.

On a previous job, we began running into data encoding issues when displaying bios of artists from all over the world. It soon became apparent that there were problems with the stored data, as sometimes the data was correctly encoded and sometimes it was not. This led programmers to implement a hodge-podge of patches, sometimes with JavaScript, sometimes with HTML charset meta tags, sometimes with PHP, and soon. Soon, we ended up with a list of 600,000 artist bios with double- or triple encoded information, with data being stored in different ways depending on who programmed the feature or implemented the patch. A classical technical rat’s nest.Indeed, navigating through UTF-8 related data encoding issues can be a frustrating and hair-pul...

How To Create Shortcodes In WordPress
