What controls integrator buyers search for
Controls integrator buyers search by platform, system and industry. Typical searches include “Rockwell certified system integrator”, “Ignition SCADA integrator”, “Siemens PLC programming”, “UL 508A control panel shop”, “HMI development” and “SCADA system for water treatment”.
An integrator wins those searches with 3 kinds of pages.
- A page for each platform you program, naming the versions and hardware you work with.
- A page for each industry you serve, such as food and beverage, water and pharmaceuticals, with 2 or 3 projects.
- A page for your certifications, such as CSIA certification, UL 508A and partner programs, written as text.
Every technical page needs a review by one of your engineers before it goes live.

How long SEO takes for a controls integrator
Plan on 3 to 6 months before a controls integrator’s platform pages bring steady RFQs. Each page needs an engineer’s review before it goes live. Platform pages that name a region face the least competition, so they’re the place to start.
What to ask an SEO agency before you hire one
Consider asking these 4 questions when you talk to an agency.
- How much of our engineers’ time will each page need?
- Which platform pages would you write first?
- Is SEO your main service, or part of a content or PR program?
- Who on your team has written about SCADA or DCS work before?

Questions we get
Do controls integrators need SEO if search volume is so low?
Controls integrators need SEO because each low-volume search is a plant manager with a project. A search for 'Ignition SCADA integrator' or 'DCS migration' may happen a few times a month in your region. The integrator with a clear page for that platform gets the RFQ.
What should a system integrator's website list?
A system integrator's website should list the platforms it programs, the industries it serves and the certifications it holds. Write out Rockwell, Siemens, Ignition, UL 508A panel shop and CSIA certification as text. Add 2 or 3 projects per industry with the systems commissioned.
Can a marketing agency write technical PLC and SCADA content?
A marketing agency can write technical PLC and SCADA content only with time from your engineers. Expect an interview with one of your engineers for each topic, and a review before the page goes live.
How much does marketing for a system integrator cost?
Marketing for a system integrator ranges from about $1,500 a month for SEO to $10,000 to $30,000 a month for full content and HubSpot programs at specialist agencies. The bigger programs add PR, newsletters and sales enablement. Decide which you need before you compare quotes.
