Important questions to ask digital advertising companies

Your digital presence is important to your business. You want to have a strong digital presence to gain new leads and customers for your business. To help you build your digital presence, you may enlist in the services of a digital advertising agency.

As you search for a digital advertising agency, you’ll want to ask them important questions that affect your digital advertising plan. Here are a few questions you can ask an agency.

1. What services do you offer?

As you look at companies, it is important to ask them about the services they offer. Some digital advertising companies only provide a few services, while others are full-service agencies. It is important to know what a company offers so that you can choose the right one.

It is a good idea to have a list of services you may need for your business. If you know you want to use pay-per-click (PPC) and email marketing services, you need to make sure your digital agency offers those services.

You’ll want to consider other services, too. You may not need search engine optimization (SEO) or web design services now, but they may be services you need down the line. It is important to take that into consideration because you don’t want to have to use multiple companies for your digital marketing plan.

  • 2. How much are your services?

    The cost is always an important factor. You want to know how much services cost, so you can factor the costs into your budget. When you know the cost of services, you know what services you can afford.

    Many companies will hide their prices from the competition. This makes it difficult to find out the prices they charge for their services. It is important that you ask this question when you contact them.


  • 3. What are your company values?

    This is an important question. When you are checking out companies, you want to ask them about their values. Values are an important part of building a partnership with a company.

    If a company values producing average work quickly, that may not align with your company if you value quality over production time. It’s ideal to find an agency that shares the same values as your business. It is difficult to build a valuable partnership if you aren’t on the same page as your digital advertising agency.


What does a top digital advertising agency do?

A top digital advertising agency will:

  • Research your industry and advertising opportunities
  • Learn about your audience and their needs, expectations, and pain points
  • Investigate your competitors and their ad strategies
  • Provide your business with recommendations for advertising online, like with specific networks
  • Develop your digital advertising strategy, including campaigns, ad groups, and more
  • Manage your online ad campaigns, like by modifying ad copy, bids, and landing pages
  • Give your business a summary of your digital ad campaigns’ performances
  • Ensure your company is the account owner for all ad network accounts

You should also expect top-of-the-line web advertising companies to:

  • Answer questions
  • Provide regular reports
  • Respond to phone calls, emails, and messages promptly
  • Measure campaign performance

Depending on your business, you may have additional requirements when working with a digital ad agency. If you do, outline those requirements beforehand so you can focus on the companies that match your needs.

How much does digital advertising cost?

Your budget is an important part of your business, so naturally, one of the first questions you may ask is how much does digital advertising cost?

The cost of digital advertising varies based on the services you use. Since there are so many options, the price is constantly fluctuating. Some services are more expensive than others, which can significantly raise the price.

To understand the overall cost, it is important to break down the individual cost for digital advertising services. These numbers are estimates of how much it costs to use each service. Many of these also have initial set up fees that you will need to pay.

For many of these methods, the cost is dependent upon the success of your campaign. The more successful your campaign is, the more you will pay for the service.

Now, it might seem scary that all of this can add up to a big number. You may feel as though the cost is high and the return is questionable. It is important to note that digital advertising is one of the most effective ways to market your business.

All these methods have a great return on investment (ROI) for your business. It is an investment, but this investment has a huge impact on the growth of your business.

It’s worth spending the money on these methods because they drive results. You will see an increase in traffic, which leads to an increase in revenue as well. Methods like SEO and content marketing are great for bringing new traffic to your site.

You will also see an increase in leads. PPC and email marketing generating great leads for your business. These are leads that you can nurture towards conversion.

Lastly, these methods drive conversions for your business. Each of these methods has a unique way of promoting conversions amongst your target audience. By investing in these methods, you will see better results with your digital advertising campaign.

How long does digital advertising take to set up and produce results?

Once you know you want to develop a digital advertising plan, you will start picking methods for your business. As you select your methods, you may wonder how long it will take to set them up and see results.

Each method is unique. You will need to look at each method to understand how quickly it will produce results.

1. PPC

PPC advertising produces results quickly. Once you have a PPC campaign established, you can start seeing results as soon as your campaign launches.

It doesn’t take long to set up a PPC campaign. You’ll need to first conduct keyword research to figure out the most beneficial keywords to target, and then you’ll make your bid for those keywords.

If your ad wins a bid, it will appear in search engines and begin driving traffic to your website immediately. It’s an extremely cost-effective strategy since you get to choose just how much you’ll pay for each ad in the bidding process.

2. Email marketing

Email marketing is another method that you can see immediate results. Once you’ve sent an email, you connect with potential customers. You can include links to your website, links to your social profiles, and share info about upcoming events.

Emails are also extremely cost-effective and are very low in cost in general.

3. Social media marketing

Social media marketing is one of the best ways to improve brand awareness for your brand. It’s one of the few marketing strategies that allow you to get in touch with a very high number of people in a very short amount of time. Consider this, even though you aren’t friends with someone on Facebook, if one of your friends likes a status you post, their friends can also see it! That means your audience is far more expansive than you realize.

Social media marketing includes setting up social accounts, retweeting other informational sites in your industry, and sharing your own content on your platforms. It also is a way to connect with current and potential customers.

4. Content marketing

Content marketing is a method that takes time to create and see results, but if you’ve ever heard the saying “content is king,” it’s the truth. Content marketing is a great investment for your business since your website will need amazing content to be able to rank in search results.

Content marketing is the process of doing keyword research to determine the topic of your content, creating that content, implementing it on your website, and then analyzing the results. All of these steps work together to create a content marketing campaign that works to improve your website.

5. SEO

SEO is the method that takes the longest to show results. It is a process that takes time, but the results are well worth the wait.

This method focuses on boosting your website’s ranking in the search results, which in turn, drives more traffic to your website. It requires you to take certain actions, such as integrating keywords or building links, to improve your ranking. These actions don’t immediately improve your ranking, but it will gradually help your position over time.

Picking the perfect digital ad agency

Your digital advertising plan is a vital part of your business’s success. When you have a strong digital advertising plan, you can draw in new leads and conversions for your business. The next step to creating your digital advertising plan is finding the right company. You want to partner with a company that is going to bring you the best results possible. So, how do you choose the right one?

  • culture

    1. Look for results

    If you want to find the best digital ad company, you need to look for results. Working with an agency that hasn’t driven results for clients in the past is a huge risk. It could mean that they don’t have the experience, time, or tools necessary to drive results.

    When you are investigating a digital advertising agency, see if you can find a page about the results they’ve driven for previous clients. The best digital ad agencies will feature a ton of testimonials from previous clients, and will even be transparent about specific numbers in terms of results that they’ve driven.

    You should also consider looking at an ad agency’s portfolio. This will give you a good idea of their style, and if it’s one that fits your goals. If a portfolio doesn’t fit your style perfectly, you may still want to give them a call — the best agencies can change their style to fit any client.

  • testimonials

    2. Check out testimonials

    If people love the work a digital ad company does for their business, they will say it. As you look at digital ad companies, you’ll want to look for ones that have testimonials. Testimonials are when previous clients take time to talk about the great results they’ve seen from the company.

    You’ll want to make sure that the company has a wide array of testimonials from different industries. This shows that they’re not too comfortable in any one area and that they can likely adapt to drive great results for your industry, too.

  • location

    3. Look at their company culture and values

    Building a relationship with your digital ad agency is extremely important — especially if you decide you need other services. You’ll want to have the opportunity to use the same company for all of your web design and marketing needs, which can only happen by forging a great relationship.

    One way to do this is by studying their company cultures and values, and determining if they line up with yours. Are they a company that you support? Will you get along? These are things to consider before hiring an ad agency.

Is AI Changing Digital Advertising?

As of August 2026, yes — AI-driven bidding, audience targeting, and creative generation now handle much of the routine optimization work across ad platforms. That shifts what a good digital advertising agency actually does: less manual bid tweaking, more strategy, creative judgment, and knowing when to override the automation. Ask any digital advertising agency how they combine AI tools with human oversight, and how they report results beyond what the ad platforms show by default.
