What is a search engine?
To talk about search engine optimisation, we should know what a search engine is. A web search engine is a software system that runs a search in the World Wide Web and brings the most relevant results for the search queries entered by a person in the search bar.
Is Google alone a search engine?
When we think about a search engine, the first thing striking our minds is Google. Since it is heavily popular across the globe, it leads the race. But it is not the only search engine available. There are many alternatives for Google such as Yahoo, Bing, Baidu, Yandex, etc. Each search engine will give different results for the same search query. If you search SEO Brisbane in all of these engines, a number of different Brisbane SEO agencies will be listed in each. Apart from these search engines, some of the other platforms also adapt the same searching process as below,
• YouTube – get the video results matching the search query
• Amazon – gets the products related to the search query
The SEO process is the way of ranking our own sites at the top of these search engine results, whatever it may be. We can optimise our title of a YouTube video to rank higher in the search results; also we can optimise our amazon product listing also.
Crawling; Indexing, and Ranking
Once we type in our search query the search engine will start scrawling the tons of pages stored in the World Wide Web for exact pages that match our query. Once it’s done, indexing follows, i.e., the crawled pages are organized to be shown as results. Finally, the results are shown with priority to highly ranked sites to appear at the top.
