Have you ever thought when you enter a search query in your search engine, why some websites are on the top and others come later on? What is the process of ranking the websites? It is all because of a powerful web marketing technique called Search Engine Optimization or SEO as it is widely known. SEO helps the search engine to find your site and rank it higher than millions of other sites in response to a search query.
You need to understand one simple fact: Most of the people don’t scroll past the first three or four websites related to their queries. At maximum, they can search a page or two but not more than that. That is why SEO services are referred as king-maker in the startup ecosystem. A startup that nail SEO win, and those disregarding it lose.
Search Engines have two major functions: crawling and building an index, and providing search users with a ranked list of the websites they've determined are the most relevant.
1. Crawling and Indexing: The search engines automated robots called crawlers or spiders go through the Web to see what is there. They use the links as a path to reach the site. Once the engines find these pages, they decipher the code from them and store selected pieces in massive databases, to be recalled later when needed for a search query.
2. Providing answers: When a person performs an online search, the search engine scours its billions of documents and does two things: first, it returns only those results that are relevant or useful to the query; second, it ranks those results according to the popularity of the websites serving the information.
Keep in mind great content is the only thing that is going to help you earn useful and credible links. Links, links and links are the only things that matter in the SEO services. More the number of links more are the chance of getting noticed and earning popularity. It is both relevance and popularity that the process of SEO is meant to influence.
