Imagine an Indian advertiser spending the same Meta budget in October as in August and September. The ads are still running, but leads are fewer, cost per lead is higher, and return on ad spend looks weaker.This has led many advertisers to ask why Meta ads are not working in October 2026. Based on verified findings, Meta did make changes in October. India also entered its festive advertising season. But there is no confirmed proof that Meta caused a nationwide performance drop.
What changed from August–September to October
Meta announced several advertiser-facing changes in October 2026.
On 6 October, Meta announced broader AI and automation features at Advertising Week. This included wider availability of Customer Lifecycle Strategy and general availability of static-to-video generation in Advantage+ Creative. (Aurelius Media, 8 October 2026)
On 13 October, Meta’s Business Help Center confirmed that Sales, Leads, Engagement and App Promotion campaigns no longer allow ad-set-level manual placement selection. Advertisers can use placement value rules and account-level exclusions instead. (Relevant Audience, 13 October 2026)
On 17 October, Facebook, Instagram, WhatsApp and Ads Manager faced an outage lasting more than two hours. Meta said services, including Ads Manager, were restored. (The Daily Star, 19 October 2026)
Meta also announced updated Commercial Terms and Self-Serve Ad Terms on 8 October. These were reported to take effect on 30 October. (Unite AI, 17 October 2026)
Why costs stayed high
October is part of India’s festive advertising period. Navratri ran from 11 to 21 October 2026. Meta’s Festive Accelerator 2026 identifies strong festive demand, with shoppers using Meta weekly and seeking social inspiration before buying. (BW Marketing World, 21 October 2026)More advertisers bidding for the same people can raise CPM. CPM means the cost to show an ad 1,000 times. Industry forecasts expected India CPMs to rise by 30–60% from October to December. This is a forecast, not a confirmed measurement of every Indian account. (upGrowth, 18 September 2026)

Why results dropped
There is no confirmed evidence that Meta changed its auction algorithm or attribution windows in October 2026. No official Meta announcement of an “Andromeda” update or India-wide delivery problem was found.
However, three confirmed factors could affect results:
•Festive competition: More advertisers compete
during Navratri and the run-up to Diwali.
•Placement changes: Sales, Leads, Engagement and App Promotion campaigns lost ad-set-level manual placement controls.
•Platform disruption: The 17 October Ads Manager outage may have affected reporting or delivery for some advertisers during that period.
Meta also requires Conversions API value signals for “Maximize Value of Conversions.” From April 2026, new qualified-leads campaigns needed Conversions API integration, with existing campaigns affected from August 2026. (Meta Business Help Center)
What advertisers are reporting (not confirmed)
Some advertisers on Reddit reported higher CPMs, fewer conversions, and weaker performance from late September into October. These posts are anecdotal. They show concern, but they do not prove that Meta changed its system for all Indian advertisers.
No credible India-specific benchmark comparing August–September and October 2026 CPM, CPC, CPA, or ROAS was found.
How to fix Meta ads
1.Check the Delivery column. Look for “Learning,” “Learning limited,” “Review,” or “Error.”
2.Review recent edits. Budget, audience, creative, bid, or optimization changes can restart learning.
3.Compare CPM and CTR. If CPM rose but CTR stayed the same, auction competition may be the issue. If both fell, review creative and audience.
4.Check Events Manager. Review Pixel and Conversions API event volume, duplicates, and Event Match Quality.
5.Review placements. Compare Reels, Feed, Stories, and Advantage+ placements by cost per result.
6.Check Account Quality. Look for rejected ads, restrictions, or policy issues before the 30 October terms update.
