How-To Delete Google History

Best bet is this:
 clear browser cache,
 clear browser memory,
 then clear recorded history.
Do this periodically tho...;
 or, ensure that “Web History” is turned Off.

 `cause it'll start right back up everytime you start your browser,
  and, sign back into any google account.

 Any web account for that matter.

But, at least google lets you get rid of it from its active server.
But, not from any server archives.

How To do this:
  You MUST KNOW your Google -/- gmail account
    UserName and, PassWord for this!

This is for Chrome and Google accounts only!
 For any other browsers using Google accounts;
 ..just clear your browser cache. and, then go here

 Remove any extraneous or non-google extensions.
  [chrome://extensions/]
    Just click "TrashCan" icon on the right-side of the extension description.

Non-Google Extensions i would recommend:
 "Avast! Online Security" [https://www.avast.com/]
   [https://chrome.google.com/webstore/detail/avast-online-security/gomekmidlodglbbmalcneegieacbdmki]

 "HTTPS Everywhere" [https://www.eff.org/Https-everywhere]
   [https://chrome.google.com/webstore/detail/https-everywhere/gcbommkclmclpchllfjekcdonpmejbdp]

  "uBlock Origin" [https://github.com/gorhill/uBlock]
   [https://chrome.google.com/webstore/detail/ublock-origin/cjpalhdlnbpafiamejdnhcphjbkeiagm]

  "Disconnect" [https://disconnect.me/]
    [https://chrome.google.com/webstore/detail/disconnect/jeoacafpbcihiomhlakheieifhpjdfeo]

  Along with whichever Cloud app one uses....
    e.g. MEGA(.co.nz; or, .nz), Cloud.mail.ru, OneDrive, etc.

Check installed Search Engines
 [i use only Google, and, a custom Wikipedia.org search

  Plain UnOfficial Google Search
   [https://www.google.com/search?q=%s]

  Wikipedia English
   [https://en.wikipedia.org/wiki/Special:Search?search=%s&go=Go]
    Note: You can use "http://www."
        the "http://en." will change to your system language code as needed.

 Also, if you are using..
 "Disconnect.Me"
   [https://disconnect.me/]
 you may want to keep it.

Now, Clear current browser data,
    if you know how to get there, do this now.
 or,
    use the following address:
 [chrome://settings/clearBrowserData]

  change:
 "Obliterate the following items from"
   to:
 "the beginning of time"
   Make sure that PASSWORDS is NOT; i repeat NOT checked!
   Make sure that PASSWORDS is NOT; i repeat NOT checked!

Now, select what you want to disappear
"Autofill form data" is up to you..;
   i leave it unchecked

  e.g.
        √  Browsing history
        √  Download history
        √  Cookies and other site and plugin data
        √  Cached images and files
            Passwords
            Autofill form data
        √  Hosted app data
        √  Content licenses

Then, click "Clear browsing data"
   wait about 30 seconds to 2 minutes.

Turn off local web history
 Now go to your content settings:
  [chrome://settings/content]
    under "Cookies" select
    "Keep local data only until you quit your browser"


Close browser
 wait about 30 seconds to a minute.
  you will be signed out of all of "Google"
   (G+, Gmail, and, YouTube)

Reopen browser
 ..then go to:
 Google History Server
  [https://history.google.com/history/]
     you will be prompted to sign back in again. do so.
   In the Upper Right corner of the page is an icon of a gear.
    Click the little down arrow just to right of it.
    Click "Remove Items"
      In the dialog that appears change the drop down box for
      "Remove items from"
        to:
       "the beginning of time"

Close browser
 wait about 30 seconds to a minute.

This process will ensure the probability that there should be no existing "tracking cookies"
 or "active document elements"
 that might be able to read the data while you are doing this...

 Also, using Chrome's “Incognito” mode may help to eliminate
  some of the “web crap” you might pick up along the way.
  (Ctrl+Shift+N)

Chrome Reset
[chrome://settings]
 [Advanced]
  scroll to bottom of page where you'll find
    "Show advanced settings..."

Again, scroll to bottom of page where you'll now
 find the "Reset Settings" button.

you will be signed out of all of "Google".
you will have to re-"enable" all your extensions after doing this.
 [chrome://extensions/]

Also NOTE:
All this; only clears "Google recorded search history",
 NOT; the histories kept by other sites which, you may, or, may not have visited.
(as in the case of "third-party cookies"; So make sure your browser doesn't accept those. Also, Search engines, Extensions, and, Plugins, (aka:Add-Ons) will track your web activities to some extent.)

Hope this helps to confuse you a little less.
