A search engine is an online tool that assists you in locating particular pieces' information among the plethora of resources found on the Internet. When you make a request to search for something, such as typing into your favourite search engine Google, Bing or Yahoo, the search engine quickly scans its large database of web pages to return the most appropriate matching results based on what you wanted to find.
TYPES OF SEARCH ENGINE
• Crawler Search Engines Crawler search engines use automatic bots (known as crawlers, spiders etc.) to review and index web content from across the Internet.
• Directory Search Engines Directory search engines rely on people to review and organize websites into specific categories/subcategories.
• Hybrid Search Engines Hybrid search engines combine both Crawler and Directory methods of search.
• Meta Search Engines These do not have their own database. Instead, they collect results from multiple search engines and combine them into one results page.
WHAT IS SEO?
Search engine optimization (SEO) is the process that improves your website's visibility on search engines, such as Google, Bing, and Yahoo, which will increase the organic (non-paid) traffic to your site. The primary purpose of SEO is to increase the number of users that can identify your website by obtaining higher rankings in search engine results for relevant keywords/phrases. SEO involves modifying the content of the website, its architecture, the technical aspects, and getting external signals (like backlinks) that help search engines determine a website's quality, relevance, and authority based on their algorithms.
SERP (Search Engine Results Page) SERP is the term for the page that appears after you type in your query into a search engine. The results on that page can be quite complicated, as they can include more than just the standard links to websites; for example, they could also contain ads, featured snippets (quick answers), images, videos, local listings, etc. Depending on whether the searcher's intent was to find information (informational), buy something (transactional), or an exact page (navigational), the result page would vary greatly.
TYPES OF SEO:
SEO is divided into three major categories based on optimization areas.
ON-PAGE SEO
On-page SEO focuses on improving elements within the website to make it search-engine-friendly and user-friendly.
OFF-PAGE SEO
Off-page SEO helps increase the authority of your website through external activities to build trust.
TECHNICAL SEO
Technical SEO is the practice of fine-tuning a site's backend and tech features so that search engines can access it more easily (crawling) and then index it (understanding) for inclusion in their database (inclusion).
Types of Technical SEO
1. The Secure Sockets Layer (SSL)
SSL is a data exchange encryption technology between a web browser and a web server. SSL is included in the URL of secure websites (HTTPS) compared with unsecured websites (HTTP).
2. SITEMAP
A sitemap is an essential document that shows the layout of a website for search engines. The sitemap gives search engines an overview of the website's structure and allows them to access the valuable page content.
META TAGS
Meta tags are HTML elements that are positioned in the <head> section of a webpage and contain data about the webpage. Meta tags do not appear as content on the webpage, but they give search engines a way to determine what the content of the webpage is about.
Meta Tag Types
1. Title Tag The title tag defines a webpage's title and is clickable when it appears in the search engine result pages (SERPS) as a headline.
2. Meta Description A short summary describing the content of the page is referred to as a meta description. The summary displays directly beneath the title tag in the search engine results pages (SERPs).
3. Author Tag An author tag is a meta tag used to define the author or writer of the content on that page.
4. Canonical Tag The canonical tag is used to prevent duplication of content, allowing search engines to understand which version of a page is the “official” or preferred page when two or more URLs have the same or similar content.
5. Robots Meta Tag The Robots Meta Tag tells search engines how to treat a particular web page. The Robots Meta Tag gives your scenario on whether the page should be indexed, crawled, and/or link-followed by search engines.
6. Meta Keywords Tag Previously, the meta keywords tag was used to display all relevant keywords for a web page. Search engines could use the information inside the meta keyword tag to help determine what the page content is about.
