Hi friends, Every 3 months,Google updates its algorithm and many websites are hit by it.Why Google implement new algorithms and why they don't make one robust algo than implementing again & again?
Do you really think that Google can create a cheat proof algo? The reason it has to change is because spammers come up with new ways to game the system and Google engineers have to find a way to detect and discount their activities.
I suppose that's just like asking why we can't have a TOTALLY foolproof antivirus/antispyware/antimalware. I, for one, don't see how it's possible. Well, theoretically or hypothetically, it might be; but in the real world, it's not. Every time a virus/trojan/malware/spyware is cracked and the necessary safety measures implemented, folks will come up with a new script, code or idea and gain unauthorized access someway, which (again) necessitates the task of developing a new solution. This goes on continually. Think of it this way – you've installed burglar alarms, security cameras and high-tech locking systems to protect your precious belongings from mishaps like burglaries and break-ins. Does that mean no one will ever attempt to break into your house and steal your property? You just can't guarantee outrightly and fully it'll never happen! One hell-bent on doing it might as well evade skillfully the security mechanism you've put up or tamper with it or even destroy it and snatch whatever stuff they can lay their hands on. As for Google, there are and always will be limitations to the ways their algos work - even if it might not be the case apparently. No doubt, the algos can certainly chuck out some pages that violate their rules and aren't consistent. But just try to imagine the whopping number of websites that come up every single day. Do you honestly think it's possible for Google to index each and every site that's set up? Let alone scanning and going over each page with a fine-tooth comb! How much resources and capacity (pertaining both to hardware and software) it would require!! :O It's pretty clear that a foolproof algo can't be developed once and for all – at least from the way I see it. And if Google doesn't update its indexing techniques frequently or regularly, people will sure as hell find increasingly smarter ways to circumvent them and get their spam/illegitimate sites listed at top in SERPs for a long time.
Oh! nice question or concern from you Anurana! Basically, Google updates its algorithm 500 to 600 times per year, And we just only know about the major update from Google, When he wants us to know about. Why this update? very simple..... If I ask you, Why Google today are so rich? It's answer or credit goes to Google's movement, I mean it's regular algorithm updates. One of Expert name Jay Taylor said correctly, He said " Google serve higher-quality search results to their users. Essentially, Google’s algorithm updates remind us to constantly improve our websites. In return, we are rewarded with better rankings and more traffic. By making your website better, you’re making Google Search better, which is good for both Google’s bottom line and yours." So, Algorithm Changes, it is not a concern. It is an improvement that is going to provide a positive user-experience.
If they won’t update their algorithm then many will take advantage of their vulnerability especially expert spammers, hackers and the likes. Google wants to make sure that their system exploit is fool-proof as much as possible so they keep updating and improving it every now and then. Of course, computer geeks who made it their lifework to hit where Google is vulnerable always find a way to pass through.
As you Know Each year, Google changes its search algorithm around 500–600 times. Google update Algorithm like so many time update Panda, Penguin and Pigeon all are for remove spam and low quality website, All update goal is as Google has continuously been focusing on providing the best user experience and most relevant information you get when you search on google, also now a day Google is more Focus on Local & Location base Results, if you search any query than most of local business rankings more on google, for provide Batter and high qulity user exprince Google update their Algorithm and remove spam results and low qulity sites for search, is similar like we Cleaning PC or Mobile non useful apps and software for batter speed and space
But those changes can harm your SERPS even thought you don't even know that something that was ok today is very bad other day. Thats why we have build tool WebDNA.io that helps you automate process of discovering future treats in website link profile. It's is in free beta version now.
What do you mean by this? Fresh sites? As in new sites? As far as I know, Google do it to combat spam not because they "want fresh sites". Whatever that means.
after having algorithm updates many hundred sites still violating google's guideline and they still ranking even they do not have 10% content as compare to HTML, i have 5 year experience still could not understand its policy whether which site come on top. i think google make only polices but but not checks whosoever is following or not. it badly em-brassing me for SEO work how to work and now what to do for rank
Its good that Google updates algorithm because if its does not do such thing the spammer will keep on spamming and we as a user will not get the actual result from the SERP.
What a silly question, they have to keep tweaking it and will always have to keep tweaking it, as people find ways of cheating it.
