What do most people do when they need a product or a service, or when they want to ask a question? They typically turn to search engines. Therefore, for businesses, appearing in those results can mean getting in front of potential customers at the exact moment they are looking for services similar to yours.
There are two main ways to gain that visibility on the search results page.
- Search engine optimization or SEO, for short
- Paid advertising such as pay-per-click (PPC)
SEO focuses on earning a place in the organic search results. Paid advertising, on the other hand, involves paying for ads that can appear alongside and above the organic search results.
Naturally, when it comes to deciding between SEO or PPC, it’s never a matter of identifying which one is better. Each has its strengths and limitations. Both channels can form part of an effective digital marketing strategy. So, the right choice depends on different factors, including your budget and how fast you need results.
PPC may require advertising spend, but that doesn’t mean that SEO is free. SEO also require an investment of time, expertise, and resources. So, the real question is never organic search vs paid search, but what you should be investing in first.
What Is SEO?
SEO is the process of improving your website so that relevant pages can rank higher in organic search results.
A successful SEO strategy includes researching what potential customers search for and understanding the intention behind the searches. Then you can create pages that match the intentions and answer their questions.
It also means making your website search-engine-friendly:
- Easy to crawl
- Suitable technical performance
- Clear page structure
- Sufficient internal linking
- Good usability
- Authoritative backlinks
- Accurate and useful information
Therefore, the key pillars of SEO basics revolve around keyword research, on-page optimization, and link building. SEO is generally treated as an ongoing investment in your website’s organic search visibility, rather than a one-off project.
What Is PPC?
Pay-per-click advertising allows businesses to pay for visibility in search results. The best-known example is Google Ads, which enables businesses to create ads targeting particular searches. In a PPC model, you pay when someone clicks through the ad to the website.
There are other paid search pricing models, such as a performance-based CPA model, where you pay per completed action and an impression-based CPM one, which charges per thousand impressions.
However, PPC doesn’t simply allow the business that is willing to spend the most money to land the top position. In fact, Google uses an ad auction model for each search to determine which eligible ads will appear and where.
Here, several factors come together to influence the outcome of the bid:
- The advertiser’s bid
- The quality and relevance of the ad
- The quality and relevance of the landing page
- The search context
- The expected impact of additional ad assets
For a small business, this means that competing for visibility through paid search is not necessarily about matching the budget of a larger company. Indeed, creating highly relevant ads and landing pages with appropriate keywords matters too.
Unlike SEO, PPC requires careful budget management, as each click becomes an advertising cost. So, it’s crucial to attract only visitors most likely to become customers.
How SEO and PPC Work Differently
The way a business gains search visibility is the fundamental difference between SEO and PPC. This affects how quickly traffic can be generated and how long that traffic may continue. Visibility with search engine optimization vs paid advertising can vary greatly.
SEO Builds an Asset Over Time
Investing in SEO is an investment in the website. The content and pages that perform well in organic search can carry on attracting visitors long after they were originally created and published.
Search engine optimization is an ongoing process and investment. Ultimately, rankings are not fixed, as ranking algorithms can change and competitors can produce better resources. Additionally, even quality content can get outdated and requires improvement, expansion, or even refreshing to remain performant.
But on the plus side, SEO efforts are cumulative. The more you focus on creating a library of useful and valuable pages, the more authority and organic visibility you gain, instead of starting from zero every month.
PPC Buys Immediate Opportunities for Visibility
PPC works differently. When a relevant search takes place, eligible advertisers compete through the ad auction. Google runs a new auction for every search. So, an advertiser doesn’t permanently own its position in the paid results.
Paid advertising is flexible and can be adjusted to meet your needs and circumstances:
- Campaigns
- Budgets
- Bids
- Targeting
So, for instance, it can make sense to increase ad spending before an important launch or an event. PPC allows you to rent access to an audience. Access is granted for as long as you pay. Once you stop advertising expenditure, the ads stop, and so does paid search visibility.
Comparing Costs and Long-Term Investment
Cost is central to the SEO or PPC decision. But, once again, you can assume that SEO is free just because it doesn’t require an ad budget.
What SEO Actually Costs
Depending on your strategy, you could invest in SEO specialists, writers, developers, keyword research tools, technical improvements, and even website design.
Additionally, there is also a time cost. Even when SEO work is handled in-house, employees are spending hours on keyword research, content production, and page improvement. When SEO is not their main task, this can be problematic for the business.
Besides, results are not immediate. It can take several months to see ranking improvements. It can take even longer for organic search to convert visitors into customers.
What PPC Really Costs
Advertising spend is much more visible because you can see how much an individual click costs. But there are other expenses to consider:
- Campaign management
- Specialist software
- Copywriting
- Landing-page creation
- Ongoing optimization
That is why other costs are worth taking into consideration when you compare paid search vs organic search. Remember that customer acquisition cost is one factor, but profit margins and customer lifetime value should also be evaluated.
Comparing Speed and Results
A properly configured paid search campaign can generate impressions and clicks as soon as it gets approved. SEO, on the other hand, needs more time.
But generating traffic isn’t the same as generating revenue. A PPC campaign can deliver conversion data insights, which can help you identify where the budget is producing genuine business value (and it may be no value at all sometimes).
SEO has a longer runway before you notice organic search benefits. But improving a page can yield more positive results than a PPC campaign, since search intent in organic search vs paid search differs.
If you are promoting an event happening next week, for instance, it makes no sense to wait for a page to gain organic visibility. PPC is the fastest strategy. But for long-lasting services, while PPC can contribute, organic visibility lets you generate traffic constantly.
SEO vs PPC for Targeting and Traffic
Both SEO and PPC can connect your business with people actively searching for relevant information, products or services. But they provide different levels of control over who you reach at which point in the customer journey.
PPC for Greater Targeting Control
With paid search, you can concentrate your budget on searches that are valuable to your business, through:
- Keyword targeting
- Campaign location
- Device
- Ad scheduling
This is particularly useful when you want to reach people who have strong commercial intent.
Example: An accountancy firm chooses to pay for clicks from users searching for “small business accountant Manchester” instead of searches about “what expenses can a sole trader claim”.
Ultimately, in the first search, users are looking for accountant services, while the second search is purely educational.
SEO for Reaching Customers Across Their Journey
SEO helps your website attract people through ga much broader range of searches.
For example, the same accountancy firm creates useful content to answer common questions about when a sole trader needs an accountant, and which expenses they can claim. These pages exist alongside service pages that are designed for those actively looking to hire an accountant.
This approach ensures the accountancy business can reach those who are ready to convert now, and those, much earlier in the journey, who are still comparing options. Over time, those who are in the research stage can gradually prepare to make contact and convert too.
That is precisely why most businesses consider a combination of SEO and PPC to ensure they can reach people at different search intent stages in the most appropriate way.
SEO can address the needs of users who are learning and comparing, on top of those who are ready to buy.
PPC works best for users who are ready to buy or contact.
Measuring ROI From SEO and PPC
Traffic is easy to measure, but traffic alone doesn’t tell you whether your digital marketing strategy is working. Does it matter that your website is attracting 10,000 visitors each month if those visitors don’t convert? So when measuring SEO and PPC performance, you need to connect search performance with business outcomes.
ROI should be assessed in terms of business value rather than visibility alone. Whether traffic comes through paid or organic search, the question remains the same: Is the activity generating enough valuable business to justify investing in it?
Measuring SEO Performance
Useful SEO metrics are different from metrics indicating visitor growth:
- Organic traffic
- Click-through rate
- Keyword ranking
- Engagement time
- Organic conversions
But these figures also need context to reflect changes in organic traffic. Indeed, with algorithm changes and the presence of bots, sudden surges in traffic without other improvements could indicate that the additional traffic lacks commercial relevance.
SEO KPIs need to be designed around business goals, and this means they should cv consider how they contribute to revenue.
Measuring PPC Performance
PPC provides its own set of useful metrics:
- Impressions
- Clicks
- Click-through-rate
- Cost per click
- Conversation rate
- Cost per acquisition
Businesses selling online can also measure conversion value and return on ad spend.
It’s important to consider the campaign measurements as a whole. A campaign with a very low cost per click may not be advantageous if clicks rarely convert. Similarly, the opposite can be true. Expensive clicks can make commercial sense when they consistently generate valuable customers (this is why you need to check the return on ad spend).
Here, you also need to understand the importance of having a solid attribution model. Multi-touch attribution helps determine which channels contribute to revenue from search engine optimization vs paid advertising. A PPC visitor could come back later to convert through organic channels.
Advantages and Disadvantages of Each Strategy
The question of SEO or PPC involves trade-offs. SEO tends to favour long-term visibility, while PPC offers greater speed and targeting control. But neither delivers guaranteed results or works in total isolation from the other.
That is why a side-by-side comparison can make it easier to understand the key differences between the two.
| FACTOR | SEO | PPC |
| Speed | Tends to be slow | Can generate fast results |
| Direct cost per click | 0 | Yes, varying depending on individual auction bid |
| Initial work | Substantial and time-demanding | Campaign set-up required |
| Targeting control | Limited to organic ranking factors | High |
| Long-term traffic potential | Strong and cumulative | No, linked to continued spend |
| Testing speed | Slow | Fast, almost immediate |
| Predictability | Fluctuating rankings that can be slow to build | Greater control over campaigns (but not over new competitors!) |
| Scalability | Gradual | Requires additional budget |
| Content requirements | High, but can be built up over time | Relatively low excluding landing pages |
| Ongoing optimization | Absolutely | Absolutely |
The biggest advantage of SEO is its potential to build value and visibility over time. Its biggest inconvenience is that it takes a lot of time to build both value and visibility.
The biggest advantage of PPC is that you can gain instant visibility as long as you are willing to pay for it. The biggest inconvenience is that this visibility can get expensive to maintain.
Both channels require continuing involvement and work to perform.
When Should a Business Choose SEO?
SEO makes the strongest case when search demand is likely to remain relevant for the long term. If customers will still be searching for your products, services, or expertise several years from now, building organic search visibility can create a valuable source of ongoing traffic.
It can be particularly useful when customers tend to conduct substantial research before deciding to buy. Businesses that translate their expertise into content pieces to answer those early questions have a better chance of collecting leads early in their discovery journey. This enables them to guide potential customers further towards more commercially focused pages, hence generating conversions in the long term.
However, you should first determine whether there is a realistic SEO opportunity. It’s an opportunity to examine your organic presence thoroughly:
- What are relevant searches that could genuinely contribute to your business?
- Are those searches dominated by large competitors (national or international brands), or do small businesses appear too?
- What is Google displaying?
- Guides
- Product/service pages
- Videos
- Directories
- Can you realistically create something more useful than what already ranks?
- Do you have the time to create the right content when it is the most valuable?
No matter how tempting it is to publish another version of information that is already widely available from competitors, having the information out there is not a guarantee of high ranking. The key when developing your SEO strategy is to ensure that your content can address the questions that are relevant to your customers and do it by delivering more value than content that already exists. Because, in the end, prospective customers are unlikely to choose your page if they can find better content more easily elsewhere.
That’s where developing a business blog can be a helpful way of creating evergreen content that addresses the latest questions in your sector. Timing, expertise, and available resources are essential for an SEO strategy to support your business’s organic objectives and ranking.
When Should a Business Choose PPC?
PPC is particularly effective for businesses that need visibility quickly. It makes sense for a new company with little organic presence to use paid search to reach potential customers while developing the longer-term SEO strategy.
PPC also suits opportunities with limited lifespan that require visibility immediately:
- Promoting a seasonal service or event
- Announcing a product launch
- Running a short-term offer
These are situations where waiting to build organic visibility would mean missing the opportunity entirely.
However, it would be unfair to claim that speed is the only reason to choose PPC. Paid campaigns can also be valuable for testing demand.
If you are considering investing time and money into ranking organically for a trending competitive keyword, a PPC campaign can provide the opportunity to test whether people who are searching for this term are actually becoming customers. This can prevent investing time and effort (and money too, as SEO doesn’t come for free) into a long-term SEO strategy that lacks commercial value.
One word of warning about PPC: Where visitors land matters. Building a PPC strategy means creating a specific landing page for users who click on your ad. In some situations, the landing page can be your product or your service page. But in other cases, you will need to design a targeted landing page to ensure that visitor reach a page that is relevant and that can support their commercial intent.
Why Combining SEO and PPC Can Work
There is no need to choose between SEO and PPC. You don’t need to commit exclusively to one strategy. In the majority of cases, the two channels can support each other.
Use PPC Data to Inform SEO
PPC has immediate results, which means it generates data fast. For businesses needing to find out which searches are the most valuable, it’s the perfect solution to learn what produces conversions and what messages people react to.
These insights are helpful to further optimise PPC campaigns, but they can also shape SEO priorities. For instance, if a particular commercial search intent delivers positive results through PPC, it can be a good idea to improve organic visibility for the same topic, in order to address other search intents.
Does this mean that PPC can be switched off once your organic results are starting to perform well? Experts recommend avoiding siloed strategies, aka ranking for the same keywords with SEO and PPC for similar visibility benefits. Indeed, almost 4 in 10 advertised websites in search results already rank organically in the top 10 for the same keywords, which creates redundant efforts.
Use SEO to Refine PPC Investment
As organic visibility grows, businesses can reassess their advertising strategy. For instance, the cost per click can decrease, freeing up budget to target a new keyword or market.
Additionally, keywords that are ranking organically with high visibility do not necessarily require further PPC support, which means potentially stopping some paid campaigns.
However, it is important to reconsider the attribution model before pausing campaigns for terms that appear in both paid and organic search.
For a new website, the most common digital marketing strategy encourages:
- Use PPC to generate targeted traffic while developing SEO
- Adjust the balance as organic performance improves
- Use PPC more selectively
Which Strategy Is Right for Your Business?
The choice between SEO or PPC depends on what your business needs search marketing to achieve.
If you need customers quickly, then immediate visibility matters. PPC has the advantage.
If you are building an online presence, SEO is the best choice for continued visibility in search.
Most businesses will need to address both of these needs; hence, they will prefer a combined strategy.
You should also consider the worth of a customer. A high PPC acquisition cost can lead to making a small margin on individual purchases, or no margin at all.
Your available resources also matter. SEO requires useful content, technical maintenance, and patience. Outsourcing it can ensure better results, but this also comes at a cost. PPC requires an advertising budget, suitable landing pages, and ongoing campaign management. It can also be outsourced, which adds to its costs.
Finally, your digital marketing strategy is designed to evolve. This means that a specific combination of SEO and PPC that would have been suitable when the business launched may need assessing and adjusting over time.
There is no clear answer to the SEO or PPC debate. Both channels offer different advantages, and the right balance depends on your objectives, budget, and timeframe.
