Search Engien kaise kaam karta hai

Pahle se hi aapko bataya gaya hai ki jo bhi sawal ,text ,word apne browser ke search engien search me likha jata hai,usnko Keywords bola jata hai.agar aap google me "what is Search Engine in hindi " likhte hon to yee keywords hai.is Keywords ko world wide web (www) me dundh jata hai.jab ye keyword koi website ke title ya article ke content ke saah match hota hai aur tags ke saath match hota hai to usko search result me show karta hai.ye to aam aadmi ke liye tha Thoda technically samajhte hai

Search Engine tin Steps me kaam karta hai.sabse pahle Crawling,Indexing,Retrieval. in 3no ke baare me vistar me jante hai.

Crawling

Crawling ka matlab dundna .aur acche se samajh lo ek websites ke saare data ko ya website ki puri jankari ko hasil karna .is process me website ko scan karna Page ka Title kya hai,keywords ki jankari ,Content me kitne Keywords hai,Images aur koun se page me link hai website ke saath .lekin Aajkal ke Modern Crawler me sayad tak ek webpage ke pure Cache ko hi copy kar lete hai.iske saat saath page Layout kaise hai,Advertise kahan-kahan hai, Link kahan diye gaye hai ye bhi Store hota hai.

Search Engine website ko Crawl kaise karti hai? Search Engine website ko crawl ke liye Bot hote hai jo har naye aur purane pages ko search karta hai jiska Discovery bola jata hai .Bots ko Spider bhi bolte hai, jo har roz Crore pages visit karta hai.lekin hamare ya aap jaise nahi bahut tezi se read karte hai.

Google ke mutabik kariban 1 Second me 100 se 1000 pages ko visit karta hai.jab Bots ko koi naya page milta hai to vo usse Back-end Processing (Page Tile,Meta Tag,Keywords,Backlink,Image,Video) ko ke liye bhej ta hai.aur fir check karta hai ki is page ke saath koun koun se page aur linked hai.

jab bhi koi naya page milta hai to fir wahi process repeat hota hai.Crawling,Backend Processing+Indexing.iske baad hota hai.Page Indexing iske bina Google kabhi bhi sahi Search dikhye nahi de sakta hai.lekin kuch aise bhi website hai jiko aap TOR NETWORK ke jariye Search kar sakte ho.

Indexing

apne dimag pe jyada jor mat daalo ye Indexing ko samjhna bada asan hai.Indexing ek process hai .jahan Crawl ke dauran jo bhi data milta hai un sabhi data ko database me palce karna hai.ek Example lelo aapke paas Bahut saare books hai.aap un books ke author name,books name,books ke har page ko read karna Crawling hai lekin in sab details ki listing karna hi Indexing hai.ab is baat pe gaur kare Search Engine sirf ek website ko crawl nahi karta hai balki duniya me jitne bhi website hai unko Crawl Aur Indexing karti hai.

Google Search Sammelan ke mutabik Google Spider har roz karban 3 trillion pages crawl karti hai .iska matlab hai ki google ke paas world me jitna Information hai un sab ka library hai

Google Search Engine data ka bahut bada server hai jahan data hazaro lakho ki tadat me jo peta byte Diver hai vaha Store hota hai.

Ranking and Retrieval

Search engine ka ye waise aakhri step hai,lekin ye aakhri step hi bahut jyada Complex hai.kyunki jab aap kuch google me search karte ho sabse pahle search ka kaam ye hai ki jis ki jankari ko aap search kar rahe hai exact wahi information aapko mile.logo ka search engine pe tabhi bharosa hota hai jab vo user relevant content dhund nikal ke dikhati hai.iske liye google kuch algorithm ka istemal karti hai.jo algorithm kuch Parameters ke mutabik kaam karte hai.jime se kuch Content age , COntent keyword,Content page title.

Page Ranking ke liye google ke 200 factors hai .jinke jariye hi ye pata lagaya jata hai ki search karne pe page google home ke kis position pe search result dikhana chahiye.rank algorithm ko samajh pana bara muskil hai.kyunki 1 billion web pages me se kisko google search karke pahle page me show karti hai.waise to Ranking Factors ko hack karne ke liye bahut saare hackers apna dimag laga rahe hai.

Pahle Ranking ka andaj kitni baar Post me keyword istemal kiya gaya hai aur backlink kitni hai in sabse bari asani se site ko rank kiya jata tha.ab kuch saalo se google ranking factors ko dhundh nikalna bara hi muskil ho gaya hai har saal google apna algorithm badal raha hai.kyunki Google un site ko pahle aane ka mouka deta hai jo sach me mehnat kar rahe hai.kuch is tarah se in 3 steps me search engine kaam karta hai.
