In this guide, we will dive into the core principles of SEO, its benefits, types, techniques, and how it impacts online success.
Search engines use hundreds of ranking factors to determine which pages appear in search results. Some of the most important factors include:

Content Quality: Search engines prioritize high-quality, original, and informative content that answers users’ queries.
Backlinks: Links from other websites (especially authoritative ones) signal that your content is valuable and trustworthy.
User Experience: Factors such as page load speed, mobile-friendliness, and easy navigation play a role in rankings.
Keywords: Properly optimized keywords in your content, title tags, and meta descriptions help search engines understand the topic of your pages.
Domain Authority: Websites that have built up a strong reputation over time (through backlinks, content, etc.) generally rank higher.
Technical Factors: Secure (HTTPS) websites, properly structured URLs, and the presence of a sitemap can boost your ranking.
User Engagement: Metrics such as bounce rate, time on site, and click-through rate can affect how search engines perceive your content's relevance to users.

1. Search Engine Optimization How does it works Search engine function are divided into three basic stages: Crawling :-  Where content is discovered. A Web crawler is an Internet bot (Googlebot/spider, Bingbot, Slurp) which systematically browses the World Wide Web, for the purpose of Web indexing. Search engines use Web crawling or spidering software to update their web content or indexes of others sites web content. Web crawlers can copy all the pages they visit for later processing by a search engine which indexes the downloaded pages so the users can search much more efficiently. Indexing :-  Where it is analysed and stored in huge databases. Web indexing (or Internet indexing) refers to various methods for indexing the contents of a website or of the Internet as a whole. Individual websites or intranets may use a back-of-the-book index, while search engines usually use keywords and metadata to provide a more useful vocabulary for Internet or onsite searching ; and Retrieval :-  Where a user query fetches a list of relevant pages. When type in a search query, and the search engine attempts to display the most relevant documents it finds that match the query. This is the most complex step, but also the most relevant.

2. Semantic Search in SEO Google uses semantic search to enhance a users experience. It tries to understand the user intent before throwing back search results on user queries. For example :-  a user who searches for "restaurants" will be shown results from restaurants which are nearby to the users location. Since restaurants are local business, a user whose IP points to a particular locality might be more interested in restaurants near by than the one which are away. This is irrespective of the user typing the location as a part of his/her query or not. 

3. Nearest Restaurant from your current location.

4. Latent Semantic in SEO Latent Semantic Indexing (LSI) is a technique used by Google and other major search engines . In this technique contents of a webpage are crawled by a search engine and the most common words and phrases are collected and identified as the keywords for the page. Example: Looking for articles about  "Cricket"  brings up Score & Schedule of major tournament, followed by news articles about cricketers and cricket team.
