So you’ve often seen these terms around, Search Engine Optimisation (SEO) and Search Engine Marketing (SEM).
They sound so similar but yet they’re really different.
In this article, we’ll cover the biggest differences between SEO and SEM.
What Exactly Is Search Engine Optimization (SEO)?
Search Engine Optimisation (SEO) refers to the process of making technical adjustments and content marketing to get a website ranking at the top of the Google search engine organically. Unlike paid advertising, SEO relies on organic drive traffic by meeting the search engine criteria and rankings.
These technical adjustments ranged from strategic use of keywords, mobile-optimisation, and secure connections (HTTPS) and savvy content marketing efforts. Though the techniques differ, the goal of all SEO is to rank a website higher on the search results page.
Here is an example of how an organic search result looks like:
The Advantages Of SEO Over SEM
SEO allows a website to be able to obtain organic traffic without having to pay for it. This makes SEO cost-effective for the long-term, making it attractive for any businesses. Here are some of the advantages:
Cost-Free Clicks: SEO brings organic traffic without paying per click, making it a more economical choice in the long run.
- Long-Term Visibility: Once a website ranks well, it stays visible for targeted keywords, continually driving traffic without ongoing ad spend as long the content is relevant.
- Unlimited Organic Traffic: With strong SEO, there’s no cap on traffic volume from search engines, allowing potentially unlimited visitors.
- Perceived Credibility: Users often view organic results as more trustworthy compared to paid advertisements, helping to build brand credibility and user trust.
- Consistent Display for Keywords: SEO ensures that your site appears every time for a targeted keyword, unlike SEM, which depends on bidding and budget.
- Sustainable Growth: Optimisation efforts would lead to continuous traffic over time, independent of advertising budgets.
- Enhanced User Experience: SEO promotes survival of the fittest. Businesses are incentivised to create a better experience for visitors and improve engagement.
As compared to SEM, where an advertiser of a website has to pay for every click that comes through the search engine, SEO does not require the advertiser to pay and is seen as more trustworthy.
Besides, SEO allows your search result to appear every single time for a keyword that you are targeting. On the other hand, SEM might not display your search results that are based on factors such as the bidding amount, the ad score and the budget you have put in place.
Disadvantages Of SEO Over SEM
SEM search results are the first thing that people will see when they enter a search query on Google. Up to four SEM search results will appear above 10 organic search results. Here are some additional downsides:
- Slow Results: SEO is a long-term strategy, often taking months to see significant improvements in rankings and organic traffic. In contrast, SEM provides immediate results.
- Algorithm Dependence: SEO results are influenced by search engine algorithm changes. Google updates can impact your rankings overnight, making SEO unpredictable.
- High Initial Effort: It takes a lot of consistent work and ongoing effort to rank high on the search engines, whereas SEM allows a quicker setup.
- Limited Control Over Placement: You can’t control where your site appears on the results page, whereas SEM allows precise control over ad positioning.
- Challenging for Highly Competitive Keywords: Ranking organically for highly competitive keywords can be difficult when it is dominated by bigger players. SEM, however, lets you appear for competitive keywords immediately if you’re willing to bid higher.
In short, it can difficult to rank a website organically on the search engine within a short time frame.
SEO requires a lot of time and effort to produce highly relevant content on one’s website.
SEM, on the other hand, allows website visitors to find the advertisers who perform SEM as it will appear at the top of the Search Engine Results Pages (SERPs) as seen in the following screenshot:
What Exactly Is Search Engine Marketing (SEM)?Search Engine Marketing (SEM)?
Search Engine Marketing (SEM), also known as Pay-Per-Click (PPC) advertising or Google Ads is a digital marketing strategy that allows a website to appear on the top of the search engines. Unlike SEO, which relies on organic optimisation to improve rankings, SEM gives businesses immediate visibility by displaying ads in top positions through bidding the keywords.
Naturally, the more competitive the keyword is, the higher the bid.
Do you own a local business or an E-Commerce store? Are you in the Fast-Moving Consumer Goods (FMCG) industry?
Then SEM would be able to help you acquire more traffic and customers if you use them.
Ultimately, the goal is to acquire more leads and sales for your business.
Advantages Of SEM As Compared To SEO
One obvious advantage of SEM over SEO is that it allows your website to be seen on the top of the Google search engines instantaneously.
You need not wait for weeks, months, or even years for your website to appear on the top of the Search Engine Results Pages (SERPs). However, there are other advantages too.
Optimised For Seasonal And Short-Term Campaigns
SEM is ideal for seasonal promotions or short-term campaigns, as it provides immediate exposure that aligns with peak shopping periods or events. Since it’s only within a short time-frame, SEM provides a burst of traffic within a set budget.
Precise Targeting Options
SEM offers detailed targeting capabilities, allowing advertisers to reach specific audiences based on demographics and their location. SEO doesn’t offer this level of control, since organic visibility depends on search engine algorithms.
Full Control Over Ad Placement
With SEM, businesses can control their ad placement and determine when and where their ads appear based on their bidding. SEO rankings are organic and are not guaranteed.
Flexibility and Quick Adjustments
SEM campaigns can be adjusted quickly based on their performance. This makes it flexible when there is change in market conditions or readjustments need to be made. SEO changes may take weeks or months to reflect in search rankings.
Clearer ROI Tracking
SEM provides detailed metrics on cost-per-click (CPC), conversion rates, and return on ad spend (ROAS), making it easier to calculate exact ROI.
For SEM results, you will be able to have four4 results that appear on the top of the Search Engines, which is the first thing that searchers would see.
This would position you at the top and acquire website traffic.
Disadvantages Of SEM Compared To SEO
Unfortunately, SEM does have drawbacks as well.
Each time a website visitor clicks onto an SEM search result, the advertiser would need to pay an advertising cost.
This click could range anywhere between $0.50 all the way to $50. The cost depends on the competitiveness of the keyword and the number of people bidding for it. But there is more to cost and budgeting to the downside of SEM.
Click Fraud Risk
One of the least talked about risks in SEM is click fraud, where competitors or malicious users may intentionally click on ads to deplete budgets without genuine interest in the products or services. SEO doesn’t face this issue, as organic clicks are not charged.
Bad For Long-term Growth
SEM provides short-term visibility, your ads only appear as long as you’re actively bidding and paying. SEO, in contrast, builds long-term, sustainable visibility that remains even after optimization efforts, giving it lasting value.
Limited Credibility With Users
People tend to trust organic search results more than paid ads, as they perceive organic results as more credible and relevant. SEM ads are often ignored by users who prefer organic listings, reducing engagement potential for some demographics.
Competitive And Costly For Popular Keywords
For highly competitive keywords, SEM can be expensive, as advertisers have to bid against others, often driving up the cost-per-click (CPC). This can make SEM less viable for small businesses or startups with limited budgets, especially for popular terms where CPCs are high.
Ad Fatigue
SEM ads can experience diminishing effectiveness over time as users become accustomed to seeing the same ads repeatedly, potentially leading to ad fatigue. SEO avoids this issue, as organic results don’t feel as repetitive or intrusive to users.

By checking on the Search Difficulty and Paid Difficulty, you will have a better understanding of what the competition is like for SEO and SEM.
Furthermore, you could use SEM as a testing ground to see the quality of leads and business that you might receive, before heavily investing in an SEO campaign.
Does Running SEM Help With SEO?
Contrary to popular belief, SEM does not help with the rankings on SEO at least not directly.
SEO rankings are independent of SEM.
Although both platforms are served by Google, Google does not favour an organic search result over any other search result because they have run Google Ads.
However, while SEM doesn’t directly impact SEO rankings, it can still provide indirect benefits that support your overall SEO strategy. For example, SEM campaigns offer valuable insights into which keywords, ad copy, and landing pages drive the most user engagement.
