The 24 hour bidding schedule for AdWords

The 24 hour bidding schedule for AdWords

We’ve written an AdWords script to let you bid 24 times a day, 7 days a week

We often find that ROI and conversion rates are extremely variable at different times of the day and on different days of the week. However the standard Google Ad Scheduling only allows for six bidding windows in one day – not nearly enough if you’re as data-driven as we are.

Therefore we built a custom ad scheduling tool that changes bids every hour of every day – that’s four times more responsive that Adwords, Marin and Kenshoo. This ensures that we’re bidding more aggressively at optimal times and maximising the efficiency of our accounts.

If you’ve not run a script before please read our Introduction to AdWords Scripts. For more open-source fun check out our AdWords Scripts directory. And if you want to use some of our technology that’s arrived back from the future then sign up for one of our paid plans on the Brainlabs Tech Stack.

Before running it, you first need to make sure you’ve got the correct settings. There are a few things to configure:

(1) The bid multipliers run from a Google spreadsheet and the URL needs to be inserted into the code as spreadsheetUrl. We suggest you copy our template sheet and set your bids up in it. The doc should look something like this:

In cells B2 to H25, input the bid multipliers: a 0% bid multiplier doesn’t change any bids, and a 25%/-25% bid multiplier increases/decreases bids by 25%. -100%, or a blank cell, mean the ads will be turned off.

If you want to use mobile multipliers as well, they go in the second sheet of the same spreadsheet.

(2) You need to set the variable shoppingCampaigns to true if you want to use it on shopping campaigns, or to false to use it on Search or Display campaigns.

(3) Set runMobileBids to true if you want to change your mobile bid adjustments every hour, or set it to false if you only want to change the ad schedules.

(4) If you only want to use these multipliers on some campaigns, use excludeCampaignNameContains and includeCampaignNameContains to say what should or shouldn’t be in the campaign names.

You then need to set up a schedule so the script runs hourly. It will continually update the ad schedules, so the next few hours are always filled in.

And now all that’s left to do is sit back and see overall conversion rates rocket!

* Advanced ad scheduling
* This script will apply ad schedules to campaigns or shopping campaigns and set
* the ad schedule bid modifier and mobile bid modifier at each hour according to
* multiplier timetables in a Google sheet.
* This version creates schedules with modifiers for 4 hours, then fills the rest
* of the day and the other days of the week with schedules with no modifier as a
* fail safe.
* Version: 3.0
* Updated to allow -100% bids, change mobile adjustments and create fail safes.

    Will 0% stop the ads from showing for the hours I don’t want the ads to run? – thanks.

    • Daniel Gilbert

      Hey Andrew,

      0% means no multiplier, so won’t stop your ads. -90% is the closest you can get to turning them off. Unfortunately Gogole doesn’t allow a -100% multiplier!

  • Nate Torvik

    I’m running version 2.0 of this script currently for a client and testing it out! Are you supposed to see previous and new values within the change log summary for each hour?

    August 24, 2015 at 6:54 pm
    • Daniel Gilbert

      You’ll only see the multipliers for the next few hours. But in Change History you should see a log of all the multipliers being changed!

      August 24, 2015 at 6:58 pm
      • Nate Torvik

        Hmm…well then I must’ve implemented something incorrectly. I’m not sure how to troubleshoot it, it looks like everything is set up the same, but I’m not getting any previous or new values!

        August 24, 2015 at 7:58 pm
      • disqus_9F4ROxTm7u

        Similarly – I’m not seeing any previous or new values, any idea where this problem may stem from?

        April 27, 2016 at 4:22 pm

    not sure how this is different than the real time bidding script, in strategy that is, if goal is position lets say. does this script actually create 24 hours time day parts, exceeding the 6 limit? how can you set a bid modifier for a day part that doesn’t exist? sorry for being dense.

    September 22, 2015 at 7:08 am
    • Daniel Gilbert

      Hey – yes it is different! Exactly as you say – this script creates 24 day parts, exceeding the normal limit. What’s happening is that every hour we are over-writing the day parts for the next 3 hours meaning that we can set them as we like.

      What this means is that it’s not really related to position at all. You could decide to bid 50% higher at 8pm on a Saturday because your ROI is better then.

      • PPCPROZ

        Hi Daniel, question: would i see these day part in the settings / ad schedule, or are these “virutal” day parts accessible only from within the script? for position goal though… would it not suffice only to run this 24 hour script, assuming the baseline bids are set appropriately? when would you recommend hourly script running with real time bid for position concurrently, or not?

        September 22, 2015 at 7:53 am
        • Daniel Gilbert

          Yep you’ll see them in the settings.

          I wouldn’t recommend running them concurrently as they’re doing different things. The position bidding script is responding to changing competitor activity to target a position.

          September 22, 2015 at 7:58 am
          • PPCPROZ

            “doing different things”… again, if goal is position… supposing that setting “discounted” ie. lower bids for different hours, ie. weekend or evening would be more or less a “one time” setting, whereas realtime bidding would more likely be the primary lever especially in terms of seasonality…. then real time bidding script would make more sense for me, as the “primary” lever? that being said I would still like to setup 24 hour day parts, but perhaps only for setting them up, not for bidding to position the script, but having the option to manually adjust day parts would be phenomenal, at the hourly level.

            “set var britishSummerTime to true or false depending on whether it’s BST or GMT” British summer time or greenich mean time? what if i want to set to usa time zone?

          i see that the google sheet has a second tab for mobile / mobile compounded bids… i’d like to run separate scripts for desktop/tablet vs smartphone campaigns. how to proceed here?

    I’m receiving Script runtime error – TypeError: Cannot call method “getRange” of null. (line 43)

    Any ideas?

    • Michael

      Hi Lee,

      Not sure if this is what’s causing your problem, but I was getting the same error and it turns out the sheet name got changed, which is what caused the issue.

      Line 43 of the script is:
      var sheet = spreadsheet.getSheetByName(“Schedule”);

      Make sure the name in quotes (“Schedule” in my case) is the same as the name of the sheet (not file name) in your Google Drive Spreadsheet where your hourly bid adjustments are.

      Hope that does the trick for you!

    Hey Guys,

    Thanks for this script! I’m receiving an error on line 44 where the notice says I’m missing this element “]”, however, my there is an “]” after my campaign name. Here’s the line of code without my campaign listed:

    var includeCampaignNameContains = [];

    November 20, 2015 at 7:52 pm
    • Tamsin Mehew

      Does your campaign name contain a quote mark?
      You can get that error if you’re using apostrophes as quote marks and there’s also an apostrophe in the name, like
      var includeCampaignNameContains = [‘O’Clock’];
      To get around that you can use double quote marks to surround the name, or put a backslash before the apostrophe:
      var includeCampaignNameContains = [“O’Clock”];
      var includeCampaignNameContains = [‘O’Clock’];

      November 23, 2015 at 10:27 am
      • disqus_9F4ROxTm7u

        I’m experiencing the same issue, with no apostrophes involved. I’ve tried inserting the backslash in various locations and still run into the problem. Any ideas?

  • Hannu Hokkanen

    Does the script work with Dynamic Search Ads campaigns as well? There’s no time scheduling in campaign settings, however when I run the script in these campaigns, I can see from the change history that some changes have been made?

    December 29, 2015 at 7:25 am
    • Daniel Gilbert

      Not sure Hannu, never used DSA successfully!

      I doubt it – if there’s no ad scheduling the script can’t over-ride anything.

    Should I need to create daily schedule for this script or just run it one time?

      Anyone there that can help?

      January 14, 2016 at 2:30 pm
      • Daniel Gilbert

        It’s only meant to update the next few hours – so when you ran it on Tuesday it updated Tuesday’s schedule. The idea is to run it on an hourly basis (schedule that in scripts) so that you’re always updating the next few hours. Happy bidding!

        January 14, 2016 at 2:32 pm

          Should I set schedule to run this script on hourly basis?

    in the case of google shopping have several CPCs set for different products, you will change the% of each product?

    Fantastic Script, thank you for sharing all your scripts and knowledge. I’m fairly new to Adwords Scripts. How can I check the result of the bid changes (to ensure that the script is working properly)? The changes of CPC based on this script. What campaign setting is best used for this script to work, with a max CPC setting, will this still work?

    Seems like an amazing script! I’ve set this up to run with a new client but before I let this script run I’m curious are you able to see the hourly stats in ad schedule under settings after I run it? As in, will I be able to see the day and time and click/impressions/ctr etc data under my Campaign’s Ad Schedule settings?

    Fine work!

    February 23, 2016 at 9:56 pm
  • Denise Smith

    The script is only working on campaigns that I have paused, even though I have not included or excluded any campaigns. Any thoughts? One campaign is working, but it has a schedule of “all day” even though the spreadsheet is clearly marked by hour of increases and decreases.

    March 2, 2016 at 7:29 pm
  • persvanstrom

    Is it possible to run this script based on Labels instead of campaign names? Include and Exclude…

    Hi, thanks for this script. But when I run/preview it – no changes in campaigns (I set different bid adjustments)

    Hi! I’m running into an issue where the preview doesn’t show old and new values. Anyone else run into this?
