What does a Facebook ads agency in Mumbai do?
+A Facebook Ads agency in Mumbai plans, manages, and optimises paid campaigns on Meta platforms such as Facebook and Instagram to generate measurable leads, sales, and revenue. Campaigns are structured around metrics like ROAS, cost per acquisition, and conversion rate rather than vanity metrics.
What is the difference between a Facebook ads agency and a Meta ads agency?
+A Facebook Ads agency focuses specifically on paid acquisition through Meta platforms, while a general digital marketing agency may handle SEO, content, and social media. Facebook Ads agencies specialise in audience targeting, creative testing, and scaling paid campaigns for revenue growth.
How much should I spend on Facebook ads in Mumbai?
+Facebook Ads services typically include campaign strategy, audience targeting, creative testing, ad production, retargeting campaigns, funnel optimisation, and conversion tracking using tools like Meta Pixel and GA4.
How long does it take for Facebook ads to start working?
+Meta's algorithm typically needs 7–14 days of data per ad set to exit the learning phase and start optimising effectively. For most brands the first 30 days are a structured testing phase — campaigns are built, creatives are tested and initial audience data is collected. Consistent, optimised ROAS usually comes in by days 45–60 as winning creatives and audiences are identified and scaled. Brands with strong offers and good creative see results faster — which is why our creative strategy work is done before campaigns go live, not after.
Do you handle creative production for Facebook ads?
+Yes. Creative is one of the highest-impact variables in any Facebook ads campaign — and most agencies treat it as an afterthought. At OneAgencz we build ad creative as part of our core service. This includes hook development, ad scripts, messaging frameworks, static ad design and video ad briefs. We work with your existing assets or build from scratch depending on what your campaigns need. A Facebook ads agency near me that doesn't take creative seriously is leaving significant ROAS on the table.
What industries do you run Facebook ads for?
+We run Facebook and Meta ads for D2C and ecommerce brands, real estate businesses, coaches and info-product creators, and service-based companies. Our strongest track record is in ecommerce — where we have delivered 3x to 6x ROAS across beauty, fashion, lifestyle and consumer product categories. For real estate and coaching businesses we specialise in high-quality lead generation campaigns that prioritise lead intent over lead volume.
Can a Facebook ads agency near me help with Instagram ads too?
+Yes — Facebook and Instagram ads are managed through the same Meta Ads Manager platform. When you work with OneAgencz as your Facebook ads agency in Mumbai, your campaigns run across both Facebook and Instagram placements simultaneously. We build placement strategies that allocate budget intelligently across Facebook feed, Instagram feed, Reels and Stories based on where your specific audience converts most efficiently — rather than running the same creative across every placement and hoping for the best.
