What is the difference between SEO and SEM?
The difference between SEO and SEM is subtle.
SEO focuses on optimizing your website to appear higher in search results so you can capture more organic traffic. SEM focuses on using SEO and paid strategies, like pay-per-click (PPC) advertising, to bring more organic and paid traffic to your site.
SEO vs. SEM: Comparing the differences & similarities
Now that we’ve answered the question “what is the difference between SEO and SEM,” we want to compare the two strategies and answer questions, like “How much does SEM cost?” and “How long does SEO take?” Get answers to these questions (and more) below:
How much do SEM and SEO cost?
Pricing for SEM and SEO depends on several factors, including:
- And more
In most cases, though, your average mid-sized business will invest the following into SEO and SEM:
Keep in mind, your company may invest a different amount depending on your industry, goals, and overall marketing strategy. That doesn’t mean you should ignore these numbers. Instead, use them as a reference when building your budget.
How long do SEO and SEM take to work?
- SEO: Around three to six months
- SEM: Instant, or as soon as your ads launch
A variety of factors can affect your turnaround time for results.
For example, your SEM campaign may not deliver results right away.
Instead, you may need a few weeks of advertising data to improve your targeting to increase your conversion rates. Or, your SEO campaign may need even more time due to building backlinks or fixing issues from an SEO audit.
Which is better, SEM or SEO?
We’ve already talked about the difference between SEO and SEM, but which one is better for your marketing campaign? What are the benefits of SEO and SEM?
SEO and SEM each offer benefits that your business shouldn’t ignore. Ideally, you should use both. If you can only choose one, though, pick SEO.
SEO provides a reliable and effective strategy for earning website traffic, leads, and revenue.
Even though digital advertising is economical when it comes to price, it can become costly when it’s your sole resource for driving traffic, leads, and sales.
For the best results, build an SEO strategy that includes SEM. This kind of approach gives your business a diverse and comprehensive approach to marketing yourself online, leading to more traffic, leads, and sales from multiple channels, including search, paid, and social. Together, SEM and SEO work better.
When should I use SEO vs. SEM?
While SEO is the preferred choice in many cases, some situations benefit more from SEM vs. SEO.
For example, you should use SEO when:
- You can wait three to six months to start seeing traffic, leads, and online sales
- You want to use a digital marketing strategy that isn’t dependent on having a monthly ad spend
- You have the time and resources (or your SEO agency does) to manage SEO proactively
In comparison, you should use SEM when:
- You need to generate traffic, leads, or sales immediately
- You want to have a presence in high-competition search results without the wait of SEO
- You have the time, resources, and budget to manage your ads weekly
Overall, choosing between SEM and SEO depends on what you want and how fast you want it.

What is SEO?
At its core, SEO is the practice of making your website as easy to use as possible.
When you do that, Google and other search engines will notice that your site provides value to your visitors. Then, they’ll start ranking you above your competitors in search results.
That boost in your ranking will attract more users who will have a great experience and show search engines that you’re a valuable and helpful resource in your industry.
This cycle continues as you work on your site, particularly when you follow SEO best practices.
How does SEO work?
SEO involves a ton of different activities — both on your site and around the web. These activities typically fall into two categories:
- On-page SEO: On-page SEO refers to optimization efforts that happen on your website, like updating a title tag, publishing a new blog post, or improving page speed. You have complete control when it comes to on-page SEO.
- Off-page SEO: Off-page SEO refers to optimization efforts that happen off your website, like conducting outreach, optimizing social media profiles, or sharing content.
You have some control when it comes to off-page SEO, but not a lot.
A few key SEO action items typically include:
- Optimizing page titles and meta descriptions
- Keyword research and analysis
- Site and server optimization
- Content creation and optimization
With these practices — and others we haven’t listed — you tell search engine users exactly what to expect from your page and then deliver with your body text, multimedia, and other site elements. This shows your visitors that your business is savvy and in-tune with the needs of your customer base.
What are the advantages of SEO vs. SEM?
The advantages of SEO over SEM include:
SEO builds trust
SEO demonstrates your company’s value to those who may not have known about you before. And if they did know about you, then you prove that you’re an excellent resource on any question they have for your industry.
That establishes trust, which makes it easier for site visitors to convert into full-paying customers.
SEO requires zero ad spend
Compared to SEM, which often focuses on paid strategies that demand a monthly ad spend, SEO requires zero ad spend. Your business can invest in SEO each month by producing content, conducting outreach, and optimizing existing pages, and then get traffic from that investment throughout the year.
SEO works 24/7
When it comes to SEO and SEM, SEO works for your business 24/7. That’s because SEO drives traffic to your website every day of the week. In comparison, SEM requires an ad spend to run and depending on your ad settings, your ads may only run on specific days and times.
What are the disadvantages of SEO vs. SEM?
The disadvantages of SEO over SEM include:
SEO requires maintenance
SEO isn’t a once-and-done task, though. You have to maintain your rankings, especially as competitors crop up and try to steal your spot in search results.
It’s also important that you expand your SEO strategy over time so you can build off of the progress you established your first time around. With that in mind, SEO is a process.
It takes time, patience, and hard work, but the results are worth the effort.
SEO takes time
Companies must practice patience when it comes to SEO. Since SEO doesn’t deliver immediate results, many businesses must wait three to six months to see increases in rankings, traffic, and sales. SEO is worth the wait, but if your company needs immediate results, you may want to use SEM instead.
Now that we’ve checked out SEO, let’s take a look at SEM.

What is SEM?
SEM is a general term that includes SEO and a variety of paid advertising strategies conducted within search engines.
Five popular SEM strategies include:
Often, companies cherry-pick the SEM strategies they’d like to use to fit their specific needs.
A company that just started its website might concentrate on branded search advertisements and PPC to get an early foothold online, while a company that’s been online for 10 years may focus on converting its existing traffic with CRO.
How does SEM work?
Like SEO, SEM operates on several different tactics, including:
- Account structure: Your account structure, which moves from account to campaign to ad group to ad, helps your business organize your ad strategy and optimize your ad spend. For example, ads about women’s sneakers should (generally) occupy the same ad campaign.
- Bids: Your bid determines how much your company will pay (at most) for a click on your ad. Some platforms, like Google Ads, offer automated bidding options that can help your business accomplish its unique goals while still staying within your ad budget.
- Quality Score: Your Quality Score, which is a measurement specific to Google Ads, represents the quality and relevancy of your ad.
A high Quality Score translates to a lower cost-per-click (CPC), as well as better ad placements.
- Ad assets: Your ad assets range from your copy to your images to your video. When you optimize your ad assets, you increase your business’s chances of delivering relevant ads that improve your click-through rate (CTR).
If you plan to use SEM vs. SEO, research the different ad platforms, like Google Ads, Microsoft Advertising, and Facebook Advertising. That way, you can learn how they grade and deliver ads so you can optimize your ads for the best performance.
What are the advantages of SEM vs. SEO?
Some of the advantages of SEM over SEO include:
SEM creates an immediate impact
One key advantage of paid strategies within SEM is that they can have an immediate impact. You are in total control of PPC campaigns: Who sees your ad, how much you pay, when your ads are displayed, and much more.
SEM delivers targeted ads
A wide-ranging SEM strategy is great for businesses who want highly targeted campaigns across a large audience. You can craft unique advertising messages to different groups of people across a variety of mediums.
Most companies will be fine only using a few strategies, though.
Small, mid-sized, and even large companies don’t usually need to use every SEM strategy at once.
SEM serves as a cost-effective strategy
Another key part of SEM‘s appeal is that it’s so cost-effective.
When you partner with an agency, you may pay a few hundred or thousand dollars for the service you get. The payoff is huge, though. It’s also completely trackable through the use of analytics software.
SEM is more affordable, cost-effective, and trackable than something like a billboard or television commercial. While you can continue using traditional advertising with SEM, many companies find that they can just use SEM and succeed just fine.
For the companies that want to go really big with their marketing, it’s always an option to use SEM and traditional advertising together.
What are the disadvantages of SEM vs. SEO?
Some of the disadvantages of SEM over SEO include:
SEM requires a monthly ad spend
Besides the cost of developing and managing your SEM campaigns, you must also set aside funds for running your ad campaigns — or your monthly ad spend. If you don’t have a monthly ad spend, your ads don’t run, which can lead to a sudden (and instant) drop in traffic, leads, and sales.
SEM targets bottom-of-the-funnel users
While companies like the ready-to-buy mindset of bottom-of-the-funnel users, limiting yourself to this section of the buying funnel can make you miss out on valuable top- and middle-of-the-funnel users.
With SEO, for instance, you can capture and nurture those users into your next buyer. When it comes to SEM, it offers your business a fast way to earn some revenue.
However, the challenge is that SEM requires a constant investment of your time and money to deliver that revenue, which can cut into your return on investment.
[Table] SEO vs. SEM comparison
SEO (search engine optimization) refers to the practice of refining your website to make it perform better in search engines like Google. SEM (search engine marketing) refers to marketing activities involving search engines, like SEO and pay-per-click (PPC), local listings on search engines, and more.
