The best SEM agencies to consider in 2024

Selecting the top SEM companies was easy because we’ve been in the business for over a decade and have seen the excellent work of other agencies. So we’re not just throwing together a top list based on what others are saying — these are hand-selected by us.

These SEM firms made it to the list because of their quality and expertise in the industry. In fact, we refer prospects to them when they aren’t the best fit for our agency.

The SEM agencies we listed made it to the top because of their:

• Years of experience
• Awards won
• Partnership with Google
• Organic search and social presence for their own brand
• Impressive client base (multiple companies across multiple industries)

So without further ado, let’s jump into the top 12 SEM agencies.

1.  HawkSEM

   

   HawkSEM makes it to the top of the list because of our wide-ranging services and expertise across various fields. We work with countless small businesses and enterprises, including those in B2B, B2C, eCommerce, software-as-a-service (SaaS), finance, healthcare, education, and professional services.

   Odds are, if you need to build your online presence, traffic, and conversions, we can help you get the job done.

   If you’re looking for a well-rounded search engine marketing strategy, we can build and execute it for you. But don’t just take our word for it. We have numerous case studies to back this claim.

   For example, Caring Places Management, an assisted living services provider, partnered with HawkSEM to drive more organic traffic to its website from the SERPs (search engine results pages). They worked with another agency before, but to no avail.

   After developing a solid, long-term SEO strategy, we put it into action and monitored their site’s performance. This included developing blog categories and filters, and optimizing existing content for high-value keywords.

   The end result: triple the keyword rankings and a 79% increase in website traffic. Our proprietary software, ConversionIQ, makes keyword research easier. It pinpoints keywords that drive results, which means more quality leads coming to your site.

FAQs about SEM agencies:

What is an SEM agency?

An SEM agency is a team of digital marketing experts that help brands strategize, build, and improve their search engine marketing strategies. It consists of services like search engine optimization (SEO), pay-per-click (PPC) advertising, and content marketing. Agencies offering SEM services help businesses grow their online presence, increase brand awareness, and improve conversion rates.

How much do SEM agencies charge?

An SEM Agency will typically charge a flat fee of $2,500 – $10,000+/month. The cost for an SEM company ranges, depending on the services offered and the size of your campaigns. In certain cases, fees can be a percentage of ad spend, an hourly rate, or a performance-based fee. At HawkSEM, we typically charge a simple flat fee, without any setup costs.

However, you shouldn’t base your decision on price alone — find out about contract requirements and how long it takes to see results.

“Finding an agency with relevant experiences is key, so ask for case studies of other clients that have had similar challenges and how the agency helped solve them,” says Sam Yadegar, CEO at HawkSEM. “It’d also be nice to meet their potential account managers before you sign on. We provide that here at HawkSEM.”

How long does it take to see results on SEM campaigns?

Generally, you’ll start seeing initial results within 2-3 months. However, to achieve significant and sustainable results, it often requires 6 months or more of consistent effort and optimization.The time it takes to see results on SEM campaigns can vary depending on several factors, such as your industry, competition, budget, and campaign objectives.

What should you ask an SEM agency in a discovery call?

There’s a lot to go over on a discovery call with an SEM agency. We recommend asking the following questions:

• • What is their experience and expertise in SEM?
  • How do they develop and implement their SEM strategies?
  • What metrics do they track and report on?
  • Can they provide case studies or examples of successful campaigns? (bonus points if these examples are within your industry)
  • What is their approach to keyword research and targeting?
  • How do they optimize campaigns to improve performance?
  • What is their pricing structure and contract terms?
  • Do they offer any additional services or insights beyond SEM?

How do I choose the best SEM agency?

Here are some factors to consider when choosing the best SEM agency for your business:

• • Reputation and reviews: Research their reputation, read client testimonials, and check online reviews.
  • Experience and expertise in SEM: Look for agencies with a proven track record of successful SEM campaigns.
  • Services and capabilities: Ensure the agency offers the specific SEM services you need, such as search advertising, display advertising, or remarketing.
  • Customized strategies: Look for agencies that develop tailored strategies based on your business goals and target audiences.
  • Communication and transparency: Evaluate their communication style, responsiveness, and how transparent they are with their processes and results.
  • Pricing and ROI: Consider the agency’s pricing structure and evaluate the potential return on investment their services can deliver.
