      We could not be happier with the service we received from Dedicated Designs/Three29. Josh and Courtney were absolutely delightful to work with. We had the pleasure of working with both Josh and Courtney on the redesign of our website. They both came with a wealth of information, creative ideas and patience. They took the information we gave them and came back with a finished out, easy to navigate website design that flows seamlessly. We could not be happier! We continue to work closely with them on edits and updates to our website today. We highly recommend them for any of your website needs. The CLTRE Team

      What a great experience working with Tegan! The team is full of kind professionals who have been a joy to work with during the creation of a brand new website for a new institution. The website looks fantastic! Our staff is so pleased that we will continue working with them on our future design, hosting, and creative needs. Special thanks for John and Laura for making the website such a successful moment in our history and for being a dream team!

      The team at Tegan is the best I’ve worked with in the industry. They provide professional, cutting edge ideas and are passionate about what they do. From design to development, my client's website was flawlessly executed. They recently moved their offices from Plano to Addison which added to the drive during face-to-face meetings but the employees of Tegan have always been flexible regarding scheduling meetings, calls, and video conferences.

Frequently Asked Questions About Digital Marketing Companies

What services do digital marketing agencies provide?

Digital marketing agencies manage businesses' online advertising efforts with the core intent of improving their online presence, raising brand awareness, improving digital visibility, and helping them close more sales.  

Their portfolio covers a variety of digital marketing services, but in general, they focus on one or a combination of the following key services: 

  • Branding
  • Search engine optimization (SEO) 
  • Paid advertising/PPC
  • Social media marketing 
  • Content marketing and content creation 
  • Email marketing
  • Analytics and reporting

The portfolio of full-service digital marketing agencies often extends to influencer marketing, conversion rate optimization (CRO), web design and development, marketing automation, mobile marketing, AIO/GEO, and event planning.  

How much do digital marketing services cost?

On average, digital marketing firms charge $5,000-$500,000 per month, depending on the services, number of channels, deliverables, market, and project complexity. SEO often costs $1,000-$6,500+ per month, PPC management 10%-20% of ad spend, and social media management $1,000-$20,000 per month.

 

When can clients expect ROI from digital marketing?

The return of investment (ROI) in digital marketing follows an S-curve where costs are high initially, followed by a period of exponential profit as the data matures. In the beginning, ROI is usually negative or neutral and businesses are paying for the setup, i.e., the research, the ideation, technical audits, and creative development. Basically, it's a learning curve period of understanding which keywords, audiences, sentiments, and channels work for the intended objectives. 

For companies seeking fast return of value, paid channels are the primary choice of medium as they provide immediate cash flow while the slower, free traffic sources like SEO are being built. On the other hand, for compounding business growth, the highest ROI usually comes from content and search engine optimization. These assets can be quite beneficial but take 6 to 12 months for sustained growth

What digital channel delivers the best ROI?

Email marketing remains the most profitable advertising medium in 2026, securing $36 to $40 on average for every $1 spent. The channel works well because the business owns the contact list and doesn't have to allocate additional resources to reach the intended audience. Here's how other digital marketing channels compare: 

Channel  Average ROI 
SEO 5:1 to 10:1
PPC (Google Ads)  2:1 to 4:1
Paid social  1.5:1 to 3:1
Content marketing 4:1 to 7:1

Standard industry performance metrics categorize a 3:1 to 5:1 (earning $3 to $5 for every dollar invested) return as an indicator for sustainable growth. A ratio under 2:1 is generally classified as underperforming, necessitating a re-evaluation of the conversion funnel. 

Notably, while a 10:1 return appears highly favorable, it actually suggests that the organization is playing it too safe and should spend more money now to obtain more customers before their competitors do.  

How much should businesses invest in digital marketing on a monthly basis?

Marketing budgets vary by industry, with some companies dedicating as little as 5% from their total revenue to over 15% across competitive verticals like eCommerce and financial services. To avoid spreading their budgets too thin, this is how businesses usually disperse their marketing budgets: 

  • 40 to 50% toward search ads: Targeting people that actively look for the product/service 
  • 20 to 30% toward social media marketing and retargeting: Remaining present among people who have already visited the site 
  • 10 to 20% toward SEO services and content: Building organic traffic that lowers average cost-per-lead (CPL) over 6 to 12 months 
  • 10 to 15% toward retention (email marketing/SMS marketing): Marketing to people who have already bought from the business as it's 5x cheaper than finding new customers 

What questions should I ask before hiring a digital marketing agency?

Before hiring a digital marketing agency, ask:

  • Have you worked with businesses like mine?
  • Which marketing channels do you specialize in?
  • What is included in your pricing?
  • How will you measure performance?
  • How often will I receive reports?
  • Who will manage my account?
  • What contract terms do you require?
