Digital marketing and AI search for Sri Lankan businesses
Cerox runs social media, Meta ads and ChatGPT ads, builds automated AI content pipelines, and does SEO and GEO so Google and AI answer engines such as ChatGPT, Perplexity and Google AI Overviews can find and cite your business. Engineered, measured on enquiries, and owned by you.
Where buyers look now, and how we put you there
Buyers now discover businesses in three places: social feeds, search results, and increasingly the answers written by AI assistants. Digital marketing is the work of being present, credible and easy to contact in all three.
The audience in Sri Lanka is large. DataReportal counted 13.9 million internet users and 9.0 million social media user identities in Sri Lanka in late 2025, and Google shows AI Overviews and AI Mode to Sri Lankan searchers.

Four rules we do not bend
You own everything
Pages, ad accounts, pixels, analytics and code stay in your name, always.
No markup on ad spend
You pay platforms directly from your own account. Our fee is separate and fixed.
No fake engagement
No bought followers, likes or reviews. They break platform rules and hurt reach.
Measured on enquiries
We track leads and sales back to the channel, and report them plainly every month.
Digital marketing: common questions
What digital marketing services does Cerox offer?
+
Social media marketing, Meta ads on Facebook and Instagram, ChatGPT ads for businesses selling into markets where OpenAI has opened them, automated AI social media pipelines, and SEO with generative engine optimisation (GEO) so search engines and AI answer engines find and cite you.
Why would an engineering company do digital marketing?
+
Modern marketing runs on engineering: server-side tracking, API integrations, automation, structured data and fast websites. We build those parts ourselves instead of renting tools, and the same SEO and GEO methods run on this website.
Do we keep ownership of our accounts and data?
+
Yes. Pages, ad accounts, pixels, analytics and any software we build stay in your name. We work with partner access and hand everything back if you leave.
Do you mark up ad spend?
+
No. Ad spend is paid directly to Meta, OpenAI or the platform from your own account. Our fee is separate and agreed in advance.
Can you guarantee results?
+
No honest agency can guarantee rankings, AI citations or a return on ad spend. We agree the measures that matter, such as enquiries and cost per lead, commit to the work, and report the numbers plainly every month.
How do we start?
+
Send us a message through the contact form. We review your current pages, ads and search presence, then propose a scope and a monthly plan.
