A hierarchical list of web pages that belong to a site. HTML versions are typically part of a site’s navigation.
Google everflux symbolizes the continuous changes in the Google search results pages. It updates the entire index of a website once in a month. This process is specially called a Google Dance. Google usually updates its data on the 20th to the 28th of every month. This continuous change or updating of Google is known as Google everflux. The main aim of Google updating its index is to make their results as relevant as possible. Google has established “fresh crawl” that runs each day called freshbot. The main purpose of the fresh crawl is to update pages that change frequently. This permits Google to serve results that are up-to-date with current events. Google everflux shot to generate the freshest possible index and up-to-date data.
Google’s prime spider crawls out and begins to index the sites in its database. This procedure normally takes from 5 to 10 days. Meanwhile the spider indexes all new pages and re-indexes that pages which are already in its index.
After crawling and spidering all the sites generally Google takes two to three week delay before presenting the updated results to the public. This time interval is generally termed as “Google Dance”. In this Google tends to fluctuate from different databases. This Google dance can last in 2 or 3 days.
This is the standard cycle for Google indexing. This process is quite well accepting sites like news sites because the data changes frequently on these sites. This is because Google indexing takes near about 2 or 3 weeks to crawl.
A delay of two or three week delay is also very long when dealing with breaking news and other current events.
There are three search engine updates which are provided by Matt Cutts.
Algorithm update: In this there are changes in the search results on the larger end of the spectrum. Algorithms of search engines can change at any time but it is not easily noticeable.
Data refresh: This is the phenomenon when data is refreshed within an existing algorithm of search engines. Changes are often so small that people don’t even notice them.
Index update: Index updates occur when new indexing data is pressed out of data centers. This index updates tends to happen in about once a month. The changes in index results in Google Dance.
For updating its index, Google uses two robots to crawl the website content; they are Freshbot and Deepbot. According to their names deeeptbot are for deep crawl of web content that results in the main Google index and Freshbot crawls the website on a daily basis and is responsible for the Everflux effect
