SEO vs. SEM: What is the difference?
Search engine optimization (SEO) describes an umbrella of strategies for improving your visibility in search engine result pages (SERPs). This digital marketing tactic focuses on your organic (rather than paid) ranking or position in searches related to your industry, business, or products and services.
SEM refers to paid strategies for improving your visibility in the SERPs via paid ads. Previously, marketers used SEM to discuss organic and paid techniques. In recent years, however, SEM has become synonymous with paid-only tactics, versus paid and organic ones.
Overall, the difference between SEM and SEO is that one uses paid strategies and the other organic.
4 SEM agency pricing models you need to know
As you research SEM pricing, you’ll come across several different pricing models, including these four:
1. Percent of ad revenue
With the percent of ad revenue pricing model, your business pays for results.
Instead of paying your agency a monthly flat fee, for example, you pay based on your ad strategy’s results. This SEM agency pricing model can seem attractive to many businesses, especially SMBs, but it does come with some drawbacks.

Advantages of this SEM agency pricing model
The benefits of the percent of ad revenue pricing model include:
- You pay based on results or revenue generated
- You minimize advertising costs during slow seasons
Overall, this approach to SEM pricing offers minimal value for the short- and long-term.
Disadvantages of this SEM agency pricing model
The downsides of the percent of ad revenue pricing model include:
- Zero predictability for monthly SEM costs
- Pricing spikes during busy seasons
- Low-value, low-return targeting to generate revenue
- Payment debates for assisted conversions
While the percent of ad revenue model generates immediate interest among businesses, it often delivers little value in the long-term. The lack of predictably that comes with this SEM pricing model makes it a risky choice for companies.
2. Percent of ad spend
With the percent of ad spend pricing model, your SEM pricing depends on your monthly ad spend.
This pricing model introduces some predictability because your company determines your ad spend. Depending on your ad spend, you may pay your agency five to 20% of it.
For example, if you invest $5000 and your agency takes 14% of that, you would pay them $700 each month.

- Raises to your ad spend also raise your SEM pricing
- Payment remains consistent, even if ad campaigns underperform
Overall, the percent of ad spend model offers more advantages than disadvantages. You can predict your costs each month, as well as remove low-return strategies. Not to mention, your agency focuses on providing your business with the best results versus any results.
3. Flat rate management
With the flat rate management pricing model, you pay a flat monthly rate.
Like the percent of ad spend model, flat rate management offers predictability.
Your business can anticipate your SEM costs, which helps your team optimize your online advertising budget. Not to mention, in busy seasons, you know your SEM agency’s pricing won’t change, even if you increase your monthly ad spend.

Advantages of this SEM agency pricing model
Perks of the flat rate management model include:
- You can keep ad management costs predictable
- You can modify ad spends without increasing ad management expenses
If you’re looking for consistency, flat rate management may work well for your business.
Disadvantages of this SEM agency pricing model
Drawbacks of this pricing model from SEM agencies include:
- Paying a higher upfront cost
- Receiving fewer deliverables due to a flat-rate fee
- Experiencing add-on fees for extra services or requests
While flat-rate pricing models offer convenience and predictability, it can impact service quality. If you feature an elaborate campaign and strategy, for example, your agency may charge extra, which cancels any potential savings the flat-rate fee offered initially.
4. Capped management based on percent of ad spend
With the capped management pricing model, you pay a flat-rate fee or a percentage of your ad spend.
As an example, an agency may require 14% of your ad spend or $500 per month.
How you pay depends on whichever amount is higher.
If your company spends $5000 each month on ads, you will pay by percentage, or $700 per month, because it’s higher than $500. In comparison, if you spend $2500 on ads each month, you would pay the monthly flat-rate fee of $500. That’s because $350 (or 14% of $2500) is less than $500 per month.

Advantages of this SEM agency pricing model
Benefits of this SEM agency pricing model include:

Disadvantages of this SEM agency pricing model
Downsides of capped management pricing include:
- Pay a higher price than for in-house management
- Settle for a lower ad spend due to capped management price
- Find zero agencies within your price range
While more complex than other SEM agency pricing models, capped management is popular. Unlike other SEM pricing models, it takes advantage of both flat rate management and percent of ad spend models, which offers your business options when it comes to SEM services.
