Have you ever noticed while searching any particular topic on Google, why only some specific websites comes 1st, 2nd or 3rd in the search result?

Well that’s because of Search engine optimization (SEO), SEO is a technique of increasing the quality and quantity of website traffic by increasing visibilityof a website or a webpage to users of a web search engine.

SEO excludes the purchase of paid placement. It targets different types of search like image search, video search, academic search, news search and industry specific vertical search engines.

Optimizing a website may involve editing its content, adding content, modifying the page code by adding specific keywords in the title to make it more aware to the users. Providing backlinks is another method of SEO, because that will also help your site to get some backlinks.


Getting indexed

The leading search engines use crawlers to find pages for their algorithmic search results

Today, most people are searching on Google using a mobile device.In November 2016, Google announced a major change to the way crawling websites and started to make their index mobile-first, which means the mobile version of your website becomes the starting point for what Google includes in their index.

Preventing crawling

To avoid undesirable content in the search indexes, webmasters can instruct spiders not to crawl certain files or directories through the standardrobots.txt file in the root directory of the domain. Additionally, a page can be explicitly excluded from a search engine's database by using a meta tag specific to robots (usually <meta name="robots" content="noindex">). When a search engine visits a site, the robots.txt located in the root directoryis the first file crawled.

White hat versus black hat techniques

SEO techniques can be classified into two broad categories: techniques that search engine companies recommend as part of good design ("white hat"), and those techniques of which search engines do not approve ("black hat"). White hats tend to produce results that last a long time, whereas black hats anticipate that their sites may eventually be banned either temporarily or permanently once the search engines discover what they are doing.

SEO is performed because a website will receive more visitors from a search engine, the higher the website ranks in theSEARCH ENGINE RESULT PAGE these visitors can then be converted into customers.
