What is PPC?

Pay-Per-Click (PPC) advertising is  a model of digital marketing where advertisers pay a fee each time one of their ads is clicked on. 

Essentially, it’s a way to buy visits to your website, as opposed to earning those visits organically through other means like Search Engine Optimization (SEO). 

Businesses (like yours) can use PPC to show their ads to people who are searching for products and services you offer.  

By tailoring your ads and choosing keywords closely related to your business, you can drive targeted traffic to your site with your PPC campaigns.

PPC is one of the most effective forms of digital marketing, offering businesses unique  benefits like:

  • Immediate exposure 
  • Precise targeting 
  • Measurable results 
  • Flexibility 
  • Increased visibility



PPC is one of the most effective and immediate forms of digital marketing available. This is why businesses across industries invest more in PPC every year.


How PPC Campaigns Work

On the surface, PPC campaigns appear to simply involve setting up some ads and waiting for clicks to roll in. But behind the scenes, there’s a complex and strategic process that makes PPC work to produce profitable ROI and revenue growth. Here are some key aspects of how PPC campaigns function:


Keyword Auctions

Keywords are at the core of PPC… 

As a user searches for a given term, like “email marketing software,” an instant auction takes place for that keyword among advertisers bidding on it. 

Factors like your bid amount and Quality Score determine where your ad will rank and how much you will pay per click.


Quality Score

This metric looks at the overall quality and relevance of your ads, keywords, and landing pages. 

Ads with higher Quality Scores get preferential treatment on PPC platforms. Keeping your score high (on a 1–10 scale) leads to lower costs and better ad positions.


Ad Rank Formula

Your bid multiplied by your Quality Score = Ad Rank. 

This formula determines where your ads appear. To rank higher, focus on bidding higher on keywords that matter and improving the overall Quality Score through optimization.


Landing Pages

Once a user clicks your ad, they should arrive at a landing page that is relevant, easy to navigate, and encourages them to convert. Align your landing pages with ad messaging for a personalized and contextualized experience to boost conversion rates.


Bidding and Budgets

Set daily budgets and use bidding strategies like enhanced CPC to maximize conversions within budget. 

The bids should be adjusted based on the performance data. 

To gain insights, you should set up conversion tracking.


Advanced Features

Take advantage of advanced features like:

  • Location targeting
  • Demographic segmentation
  • Customer match
  • Responsive search ads


These can help refine your targeting.


Best PPC Platforms to Consider



The major players in PPC each offer unique advantages. 

The platforms you choose to use are determined by the goals you have and the audience you intend to reach.


Google Ads 

With a whopping 83.49% search engine market share, Google Ads is the 800-pound gorilla. 

Its massive reach, advanced features, and detailed targeting make it appealing for both B2C and B2B. 

Google Shopping ads are ideal for e-commerce brands looking to get their products in front of people ready to buy. YouTube ads also offer engaging video ad options.


Bing Ads

While smaller than Google, Bing still owns over 9.19% of search traffic

Bing Ads can be a cost-efficient option, with less competition on keywords giving better ad positions and lower costs-per-click (CPCs). 

The Microsoft Audience Network also allows Bing ads to show across additional sites.


Facebook Ads (Meta Ads)

As the top social media platform, Facebook has over 3.65 billion monthly active users—a marketer’s dream. 

Facebook’s detailed user data gives you the ability to serve  highly targeted ads based on demographics, interests, behaviors, and more. From image and video ads to Stories and Messenger ads––you have a variety of options for engaging users.


LinkedIn Ads

For B2B marketers, LinkedIn’s 500+ million professionals make it a prime platform. 

Tailor ads by:

  • Job role
  • Industry
  • Interests
  • Business goals for your targeted audience

Partner with an agency to tap into their LinkedIn campaign management expertise.


Pros/Cons of PPC vs Other Digital Marketing Forms



PPC has unique advantages that make it an essential component of every digital marketing strategy.


Search Engine Optimization (SEO)

SEO has key benefits like long-term organic growth and high-trust content. But it can take months to see results. PPC offers a faster complement for leads. Use both in tandem.


Social Media Marketing

Organic social reaches highly engaged audiences, but paid social (social media ads) expands reach. Combine organic content with paid ads for ideal social media ROI.


Email Marketing

Sending targeted emails to subscribers you already have offers outstanding ROI. 

Yet acquiring new subscribers can be a challenge. PPC can help drive new leads and subscriber sign-ups.


The common thread is that today’s savvy digital marketers use both PPC and organic methods like SEO, social media, and email together for short and long-term success. 

The immediacy and conversion-focused power of PPC, when balanced with organic growth channels, can create a comprehensive strategy that maximizes results.


Benefits of Hiring a PPC Agency

With a solid understanding of what PPC is and how it works in place, engaging the services of a PPC agency can provide immense value. 

These agencies and consultants have the expertise, tools, and experience to ensure your PPC budgets are being used efficiently and effectively.


Access to Advanced Skill Sets and Insights

Don’t underestimate the  skill and effort required to manage successful PPC campaigns.

 The most qualified PPC experts are at agencies that focus exclusively on paid search. 

They live and breathe PPC, staying on top of every new feature, algorithm update, and innovation within the major advertising platforms. 

A PPC marketing agency can identify optimization opportunities that may seem counterintuitive but have data to support them. 

They are experts that can provide insights you might never find on your own. Their strategic vision for structuring campaigns for scale is invaluable.


Proven Methodologies and Best Practices

Agencies develop time-tested processes for managing campaigns. 

With an independent, unbiased approach, they can provide a fresh look at your PPC efforts using proven methodologies. This prevents you from stagnating or relying on ineffective strategies that may have become comfortable.


Tools and Technology

Many agencies leverage proprietary technologies and tools for research, tracking, reporting, and automation that would be costly for an individual business to develop or license. 

This gives them an advantage in efficiently managing large-scale PPC efforts and extracting performance insights.


Added Human Resources

No matter the sophistication of tools, PPC still requires manual management and optimization from experts.

Agencies have teams wholly dedicated to campaign management, allowing more focus than an in-house resource stretched across many marketing channels.


Speed and Scalability

Getting PPC campaigns launched and ramped up quickly can be challenging. Especially if you’re starting from scratch. 

An agency can accelerate results through increased budget and testing velocity. Their experience also allows them to seamlessly scale spend across accounts.


Customer Acquisition Cost (CAC) Reduction

The combination of increased conversions and continuous optimization that agencies bring means your cost to acquire customers (CAC) through PPC will steadily decline.

As scale increases, they leverage experience to further reduce CAC.


With these benefits in mind, partnering with the right PPC agency can transform your paid search campaigns, unlocking significant growth and ROI. 

Identifying an agency that matches your needs takes research.

Vetting and Selecting the Right PPC Agency

PPC agencies are not created equal…

Choosing the right partner to steward your paid search campaigns takes thoughtful research and evaluation. Here are key factors to consider:


Proven Success and Case Studies

A reputable agency will have a strong portfolio of client success stories and examples of achieved results. Look for proof of  expertise in your specific industry.


Strategic Experience

Ask candidates to explain their strategic approach. Assess their knowledge of the latest platform capabilities and trends. Make sure they are thinking long-term.


Technical Capabilities

There should be a clear understanding of how to track conversions, optimize landing pages, manage large budgets, and implement other PPC fundamentals.


Communication Skills

Clear, proactive communication is a must. Make sure they’ll provide regular reporting and insights, along with quick responses.


Client Retention and Reviews

High client retention and positive reviews show an agency provides results and value. Watch for red flags like high turnover.


No Cookie-Cutter Solutions

Avoid agencies that push one-size-fits-all programs. Your strategy should align with specific objectives.


Cultural Fit

Make sure your agency aligns culturally with shared values and collaboration models. You want a trusted partner relationship.


Analyze Pricing and Contracts

Compare pricing models and look for flexible contracts rather than rigid, long-term lock-ins.


Trusting your gut during the vetting process goes a long way.


PPC Agency Pricing Models

PPC agencies use several types of pricing models. 

Being aware of the pros and cons of each helps determine the best fit.



Percentage of Ad Spend

PPC agency charges a monthly fee that is a percentage (often 10–20%) of the client’s total ad spend.

  • Pros: Aligns incentives (agency benefits from optimized spend). Easy to budget.
  • Cons: Potentially expensive as spend scales. Does not account for labor time.


Fixed Monthly Fee

A pre-set monthly fee based on the estimated workload and labor time required.

  • Pros: Predictable, consistent pricing. Accounts for labor.
  • Cons: Poor alignment of incentives if spend varies. Can underestimate or overestimate workload.


Hourly Rate Model

PPC agency charges for actual hours worked based on hourly rates for different team members.

  • Pros: Accounts for actual time invested by the agency. Strong incentive alignment.
  • Cons: Unpredictable monthly costs. Need visibility into work logs.


Performance-Based Pricing

Fees tie directly to performance KPIs like conversions, sales revenue, or ROI.

  • Pros: Places focus on results. Aligns agency success with your goals.
  • Cons: KPIs need to be realistic and measurable. Requires transparency.


Hybrid Model

Combines two or more models, like a fixed fee + percentage of spend or performance bonus.

  • Pros: Balances predictability with incentive alignment. Share the upsides of success.
  • Cons: Can be complex to calculate. Needs a clear definition.


The best fee structure provides incentive alignment while accounting for workload and reflecting a fair value exchange. Avoid rigidity; be open to optimizing the model.


When to Switch PPC Agencies

Occasionally, the need arises to switch PPC management to a new agency. 

But how do you know it’s the right time? 


Consistently Missing KPIs

If campaigns are consistently falling short of core metrics and goals with no improvement, it indicates underlying issues.


Lack of Accountability and Communication

Unresponsiveness to questions or concerns, lack of proactive optimization, and sparse reporting point to disengagement.


Churn on Your Account

High turnover of your account manager or team suggests the agency may not be investing properly in talent.


No Value Added

If nothing seems to be evolving except your monthly bill, your needs may be beyond your current partner’s capabilities.


Outdated Strategies

As Google and other platforms add features, strategies need to evolve. 

Stagnant agencies get stuck in their ways. The best ones will try new strategies.


Misalignment on Goals

Ensure your agency understands your business objectives. 

Conflicting priorities breed poor results.


Lack of Transparency

Your agency should provide clear visibility into your accounts and how they optimize ad spend.


Steadily Increasing Costs with No Value

If costs climb higher with no added value, it may be time for a change. Stay aligned on budgets.


If these issues emerge, have an open dialogue with your PPC agency first. Outline concerns and see if alignment can improve. If not, changing partners may be the best path forward.


Transitioning to a New PPC Agency



PPC brings unique advantages that make it an essential component of a complete  digital marketing strategy.

Should you decide to switch PPC marketing agencies, follow these best practices to ensure a smooth transition.


Audit Existing Accounts

Thoroughly review existing campaigns, ad groups, and keywords to gain insights before migrating.


Export Performance Data

Extract analytics and campaign data to provide the new PPC agency complete visibility into past performance.


Set Proper Account Access

Remove old PPC agency access while granting the new agency the proper permissions to manage accounts.


Develop Transition Plan and Timeline

Define all key milestones and dates upfront to prevent gaps or downtime in management.


Communicate Early and Often

Keep both old and new PPC agencies informed during all stages. Clear communication avoids problems.


Execute Parallel Campaigns

Run new agency campaigns alongside old agency efforts for an initial testing period. Learn and refine.


Monitor Campaigns Closely

Observe the new PPC agency’s campaigns daily to ensure proper setup, spending levels, and results during the transition period. Provide feedback.


Reconcile Billing

Confirm the final invoices from the old PPC marketing agency and start with clean billing with the new partner.


Ideally, transitions should allow for an initial ramp-up and testing period where the new PPC agency sets up initial campaigns and gains insights while old efforts continue running. This overlap lets you monitor performance closely. Once ready, the switchover can be made relatively seamlessly.



Managing profitable, scalable PPC campaigns requires expertise and constant optimization.
