A site can end up being found in these two ways: Crawling and indexing. These two processes are very basic in SEO that concerns whether or not a user’s request matches your searchable content.

What is Crawling?
The crawling process implies the scanning of the world-wide-web through which a search engine would discover its new or old content-for example, Google, Bing, Yahoo. Automatic programs called crawling bots, or spiders, perform the functions contained in walking.
How Crawling Works:
The search engines start with a known URL list.
Crawlers follow links on those sites to find new pages.
They process the contents, structure, and metadata of the pages.
If pages pass certain criteria, they go into a queue for indexing.
Factors Affecting Crawling:
Website Structure: A nice structure with good navigation makes it easier for crawlers to crawl all pages in an orderly fashion.
Internal Linking: Intra-page linking ensures the relevant content is discovered and prioritized by search engines.
Robots.txt File: Tells search engines which pages to crawl and which pages not to crawl.
Crawl Budget: For any site, there is some amount of resources Google allocates toward crawling and indexing; usually, content considered high quality will be prioritized.
Sitemap: An XML sitemap enables search engines to find all the pages on your website.
What is Indexing?
Indexing happens immediately after crawling; this is the time the search engines process the page and store it into the vast database, hence making it eligible to be served as a result.
How indexing works:
Googlebot processes the contents of the page, analyzing its texts and media files, i.e. pictures and videos.
Metadata (information on title tags, descriptions, and alt texts) are being thoroughly analyzed as they help to ascertain relevance.
The content gets categorized and stored in Google’s index.
The pages that pass the guidelines for quality will qualify to appear in the search results.
Factors that influence indexing:
Content Quality: Duplicate and low-quality content may not be indexed.
Canonicalization tags: Another thing, these help to resolve problems involving duplicate content by specifying an authoritative version of a page.
Mobile Optimization: Google favors content that is optimized for mobile devices.
Page loading speed: A page that loads relatively faster is prone to indexing.
HTTPS Security: Secure websites are favored in indexing.
