158% ROI from paid search campaign on Google Search Engine

Perfect Concrete Care is a start-up concrete care contractor specialising in concrete cutting, grinding, coring and scanning, based in Marrickville, NSW. Even though Perfect Concrete Care is a new company on the market; since the beginning it has been reaching net profit every month successfully. The concrete care market is competitive, there are lots of smaller and bigger companies competing on the concrete grinding, cutting, coring or scanning services market.

In 3rd quarter 2016, on behalf of Perfect Concrete Care, we ran a paid search campaign on the Google Search Engine reaching 158% return of investment (ROI) which means every $1,000.00 invested into the campaign brought more than $1,500.00 in profit.

Read on about how we performed a high quality paid search campaign on the Google Search Engine.


At the end of the day, widely defined sales is a fundamental objective of almost every single cost per click (CPC) campaign for any kind of organisation. The sales goal was keep 100% return of investment Since it is the last step of acquisition funnel together, with our client, we set up supporting site-centred communications goals:

  • Price guide download
  • Call button use
  • Contact form
  • Call-back form
  • Phone call
Marketing Strategists often divide goals into business and communications objectives. Achieving communications objectives leads to achieving business goals. Take this example: in the case shown, business goals may be defined as “Get $1,000,000 monthly takeover or keep 100% return of investment from services provided by the concrete care contractor”. Furthermore, a certain amount of phone calls or price list downloads will result in sales. Read more about interactive marketing strategies.

As the table below shows, we achieve more than 20% goal rate. This means with every fifth session, it ends with action: downloading a price list, tapping on a call button or filling out the contact forms.

First of all, we focused on the quality score. Thus, we concentrated not only on the keyword coverage, relevant ad groups or ads but also on landing pages triggered by the ads.

We, as an online marketing agency, built four paid search campaigns on main services basis: concrete grinding, concrete scanning, concrete cutting and concrete core drilling. Drilling down, ad groups were constructed as most common application of the services, e.g. floor grinding, post tension cables investigation and so on.

In the same time, we created responsive landing pages containing call to action buttons, online forms, descriptions of services and most common applications. As more than 50% (source: Google Analytics) of Perfect Concrete Care’s traffic comes from mobile devices, responsibility was required.

In order to track the performance, we set up goals on Google Analytics and used WhatConverts for numbers.

Responsive Web Design (RWD) is an idea of building websites which users can easily read on any device used. This includes: desktop, mobile phone and tablets.
