Search Engine Optimization is one of the basic and most important thing a webmaster should know if they want huge success in future. Search Engines are considered to be the most popular method of gaining quality and targeted traffic which is steady and there are less chances to loose it. Among all search engines, Google is the most visited and popular in  people which brings a lot of traffic daily to millions of websites and blogs. So it is recommended to prepare yourself for facing Google algorithm changes because day by day it is making improvements and want to make web a better place.

Backlinks are really important for every successful blog which wants to rank high in search to gain thousands of visitors, which are then generated into money. According to Google, “Backlinks are votes to your site”, this makes them more important because the more votes a link has the more it will be highly ranked. As people gained knowledge of building backlinks they started to spam other websites to generate links so they could win the race more easily but they don’t know that ‘success requires hard work’ and Google started to filter these spammy links out by introducing Penguin update and placed a penalty on these types of websites which used blackhat techniques.
