This page answers the questions covered by the article Five Google Ads Scripts I’d Still Run in 2026—and Five I’d Retire on groas.com. The article is the full, canonical source.
Direct answer: According to groas, advertisers should keep five defensive watchdogs in 2026 and retire five old optimization routines that duplicate Smart Bidding or assume outdated structures. The five to keep cover intraday budget overdelivery, an n-gram negative-keyword review queue, broken landing-page checks, zero-conversion spend flags, and daily Quality Score snapshots. If only one is installed, the article recommends Keep 4, the zero-conversion watchdog, because a silent tracking failure leaves bidding decisions without a trustworthy conversion signal.
The article recommends keeping five defensive scripts as watchdogs, not autopilots, and retiring five old optimization routines that fight automated bidding or assume Performance Max has keywords to manipulate. According to groas, most best-scripts lists are outdated because their code breaks, duplicates native features, or targets the wrong campaign structure. The keep list is intraday budget alerts, n-gram review, URL checks, zero-conversion flags, and Quality Score snapshots.

The article recommends an hourly script that flags enabled campaigns when today's spend passes OVERSPEND_THRESHOLD_PERCENT, with a default of 130. According to groas, Google can spend up to 200% of a daily budget on an individual day while balancing spend against the monthly limit. The script limits checks to 9:00 AM-6:00 PM in the account time zone and the email is a prompt to inspect a spike, not proof of a billing breach.

The article recommends a monthly n-gram miner that groups visible search terms from search_term_view into single words and adjacent word pairs. The default filters are MIN_COST of 50 and MAX_CONVERSIONS of 0, with MIN_COST set near 1.5 times target CPA, which means 60 at a $40 target CPA. According to groas, the output sheet is a review queue, never an exclusion list, and rows overlap across tokens so they should not be summed as distinct spend.

The article recommends a daily script that checks a capped set of unique final URLs from enabled ads and emails HTTP failures. The default cap is MAX_URLS_TO_CHECK of 150, scheduled daily ahead of the workday. According to groas, a 403 can mean the script was blocked rather than a broken page, so flagged URLs should be verified in a browser before changing ads.

The article recommends a watchdog that asks whether an enabled campaign has spent past a threshold today with zero recorded conversions. The default is MIN_SPEND_THRESHOLD of 150, set around 2.5 times target CPA for an individual campaign, which is 150 with a $60 target CPA. According to groas, it should be scheduled every two hours during monitored hours and treated as a prompt to check tracking and checkout before touching bids.

The article recommends retiring hourly dayparting bid adjusters, Target-CPA keyword bid manipulators, exact-match query sculptors, Performance Max search-term exclusion scripts built for Search, and Expanded Text Ad rotation testers. According to groas, Smart Bidding already considers time-of-day signals and owns auction decisions, close variants make automatic exact-negative additions prone to collisions, Performance Max structures do not provide the keyword entities old Search scripts expect, and Responsive Search Ads assemble assets dynamically. The article recommends retiring the bid-changing and auto-exclusion versions but keeping inspection and manual review.
