SEO vs SEM: How Do You Choose? Simple Answer, You Don’t!
Digital marketing can quickly turn into a nightmare if you don’t pick the right strategies to show a positive Return on Investment for your work. Many companies beginning their B2B marketing journey ask themselves: SEO vs SEM – which one should I choose?
The simple answer is: you don’t.
Asking for an opinion on whether to choose between SEO and SEM is the proverbial apples versus oranges scenario. SEO and SEM have completely different functions, goals, and intents in digital marketing.
For example, you can drive traffic via SEM tonight and potentially spend a lot of money in 2 hours and see some results, whereas any SEO campaign will take 90 to 120 days to see results.
Instead, you should consider the pros and cons of each strategy and then map this onto your company goals for the next month, three months, year and so forth.
So in this article, we’ll look at both SEO and SEM. Their pros and cons, when to use one versus the other and what to do INSTEAD of choosing between the two.
We’ll not only dig deeper into their differences but also touch on the advantages and drawbacks.
There are multiple search engines in the United States to rank on. Of course, Google takes the lion share, 88.6%. But, don’t forget other notable search engines: 6.01% Bing, 4.09% Yahoo, and .97% DuckDuckGo. But to simplify things, our suggestions and analysis in this article is primarily geared towards Google.
SEO engineers typically monitor Google results first and foremost – and with good reason:
As you can see, right above the organic search result for Digital Authority Partners, there’s an ad from Scorpion, a marketing agency, paying to have the ad shown in Google search results. For whatever reason, Scorpion either didn’t invest in SEO for this search term or decided it’s better and quicker to just pay to be at the top of search results.
But here’s the catch. If I click on that ad, which I didn’t because it would be in poor taste, Scorpion would have been charged $19 for my click according to an AHREFS data extract from April 1st 2019.
And that’s $19 dollars for one single keyword and one single click, someone using SEM would have to pay for to get that customer to a page set up by Scorpion or any other company.
In contrast, as you can see from this extract below, our own article is not only #1 for healthcare marketing, but also ranking organically for an additional 94 other keywords.
Bottom line: SEM is paid search, while SEO is organic search.
Now, let’s get cracking on the upsides and downsides of both approaches to help you make an informed decision: SEO vs SEM.
Two things stand out from this screenshot.
1. Companies paying for traffic in the form of SEM get a significantly smaller piece of the pie than companies that work hard and have their content rank organically.
2. SEM is super expensive. Let’s assume for a second that Scorpion outbid everyone else with their SEM efforts (that’s not realistic, but let’s assume it for illustration purposes). And that they only did it for this keyword not for this and the other 94 keywords our article is ranking for. 11% of 2,200 is 244. Multiplying that by 19 gives us a monthly cost of $4,598. That’s 5 grand just for one keyword.
The superiority of organic search results over SEM should not only be based on this anecdotal evidence.
In fact, according to Outbrain, the content aggregator platform, Google and other leading search engines drive 300 percent more traffic to websites than Facebook, Twitter, Instagram, and other social media sites combined.
If that’s not convincing enough, SEJ says organic search (SEO) commands 51 percent of all web traffic, while only 10 percent, 5 percent, and 34 percent originate from paid search (PPC), social sites, and all other sources respectively.
SEO doesn’t just drive quality traffic, it all increases conversions over time.
That’s right; traffic from SEO initiatives is more likely to convert into leads/sales/actions than other traffic sources. In other words, for the hypothetical example above, Scorpion would pay $5,000 per month and get only a fraction of the leads that Digital Authority Partners received by being #1 search result.
By investing in SEO campaigns, you are positioning your website to receive lots of qualified organic traffic. As a result, you are also positioning your company and business to get more leads and conversions in the long haul.
What’s even better is that organic traffic usually generates more than 40 percent of revenue for digital businesses.
Bottom line: if you offer viable solutions (products or services) and embrace an effective SEO strategy, you’ll definitely drive significant website traffic in the long-term. This will result in more lead generation, more conversions, increased sales, and eventually spruce up your revenue.
It would be close to impossible for any agency to ever rank as number 1 search result for this search term. ‘Best’ requires choices. Aka – it’s a term often reserved for listicles and third party magazines that compare and review the best companies in a specific field. Which is why, in my case, because I’m in Chicago, Google’s organic search results show listicles from Upcity and BuiltInChicago.
We as an agency would love to be on a listicle that’s on top ten search results for this term – but we would never try to organically rank for this term. That said – we occasionally run SEM campaigns from time to time for this search term. And as you can see above, 4 other agencies did the same at the time of writing.

Costs are different (SEM is always more expensive in the medium to long term), conversion rates are different, engagement rates are different.
That’s why the debate between SEO and SEM is predicated on a false premise that somehow you have to choose between the two. You don’t. And you shouldn’t!
Any consultant working at a marketing company, who’s been around the block a few times, will tell you to never prioritize one over the other.

What is SEM?



Pros of SEO
1. SEO drives quality traffic and generates great leads
Organic Google traffic is the best quality traffic out there, and with good reason. That’s because users visiting search engines are most likely looking for products, services, and solutions that you may be offering. SEO is hands down one of the most powerful inbound marketing strategies. It helps you bring quality traffic to your website, and therefore improve your lead generation. Even in terms of quantity, search engines do a bang-up job as they pull in a large amount of traffic across the web. Look at the screenshot shared before against to see estimates for organic clicks versus paid clicks. For the ‘healthcare marketing’ keyword, 11% of clicks only go to paid ads while 89% of clicks go to organic traffic.

1. SEO takes minimum three to six months to show results
As they say, Rome was not built in a day, and the same goes for SEO vs SEM. How long does it take to rank top on Google search results page? While it depends on what you do, offer, and previous SEO experience, it can take up to one year to be listed as the #1 search result in Google. If you are gunning for a spot on the first page of search results, an excellent SEO agency will take an average of 90 days to help you reach this milestone. This can be a big deal if you after instant results. However, SEO is all about the long haul. You will need to trust the process. After all, the benefits of top SEO ranking are perpetual and long-term. [bctt tweet=”An excellent SEO agency will take an average of 90 days to help you reach page one of search results” via=”no”]2. SEO is not a one and done
Good SEO is an ongoing process. It’s not a one and done strategy – you’ll have to put in hard work and time. As a rule of thumb, you have to continue to nurture your SEO efforts. Oftentimes that means that you will have to craft more refreshed and trending content on-site and off-site optimizations, adjusting your SEO strategy over time, keeping up with technical SEO, and much more. For example, Google rolled out one major SEO update in March of 2019. This impacted 56% of all rankings in Google. It is very common for Google to constantly introduce new changes – and your SEO strategy needs to change accordingly. It’s all about hard work, true. But one that will pay handsomely in the long run.3. You can get burned by working with a bad agency
Getting burned is on the scorecard here. Many people swear off SEO after they have been burned by a bad agency. Before ever choosing an agency make sure to have them show you how they’ve made clients rank #1 for their keywords. Be sure they can also explain how they do it. If they involve blackhat tactics in their process, you are better off taking your business elsewhere. We’ve put together this article with questions you should ask of any SEO agency before doing business with them. Here’s some highlights How to choose the right SEO agency that will not get you burned? Ensure you’re a good fit. Some SEO agencies specialize in a few industries, say healthcare, fintech, e-commerce, etc. While the core SEO principles are the same across almost all industries, it’s crucial to find an agency that has done plenty of legwork for brands in your niche or industry. Take a closer look at their portfolio. If you don’t like what you see, trust your business instincts and move on to the next one. Analytics and ROI tracking are crucial. You don’t have to take their word for it. Work with an SEO agency that offers trackable and quantifiable results.4. SEO isn’t cheap
5. A Google penalty can hit you hard
Shady SEO practices will definitely get your penalized and your site can get deranked. Whatever the case, it’s indeed possible to get penalized by Google for something Google thinks you’ve done wrong. An impact of a programmatic or manual penalty can be devastating to a business.6. There is no absolute ROI known before starting SEO
As far as SEO goes, you have to have some faith. You don’t know the exact ROI or impact of your efforts until months or even years later. You have to trust the process and know the outcome will be great. Now that we’ve looked at the pros and cons of SEO, let’s do the same with SEM.Pros of SEM
1. Great for instant results
If you are looking to drive urgent traffic to a time-sensitive campaign, product launch, or limited-time products or services, you stand to benefit from highly targeted PPC ads. Of course, you will have shell out pretty penny to get this urgent traffic.2. It can help supplement your SEO efforts
SEO is a longer term, more permanent marketing solution than SEM. However, SEM can be used as a great supplement to your SEO efforts, especially when it comes to your very best keywords. But the operative term is ‘supplement.’ SEM is not the type of activity you want to work on first or last. You shouldn’t get into a position where you have to choose between SEO vs SEM. Think about it. Say you divert all your budget to SEM for April. Then you start SEO in May. Then it takes 3 months, at best, before you see the results. What happened? You’ve just delayed SEO results by 4 months. Every marketer should create a set budget where SEO and SEM are leveraged at the same time. The goal is to hit some intermediate milestone in the short term with SEM but have a chunk of your budget directed at SEO – because that’s where most of the ROI comes from.3. SEM helps with visibility for very competitive search terms
If users are searching for specific terms that are associated with your business name or offerings, SEM can come in handy. It can be used to ensure that anyone who searches for these terms will click on your link at the top of the results. Additionally, there are specific terms that will take a very long time to rank organically for. Those are buy-oriented terms. And to be honest, some terms may actually be impossible to rank for organically. Example: search for ‘best marketing companies’.
4. SEM is great for retarget marketing
Both SEO and SEM can help drive some traffic to your website. But, what about retargeting those visitors that didn’t take the desired action? That’s where SEM brings its A-game. It can be a great way to retarget these visitors who come to your write or read your content but don’t convert on the first try. With proper SEM, you can tag those users and show them ads on other sites to bring them back to your site. We at Digital Authority Partners run PPC campaigns against all our articles. So even if you leave this website after reading this article, you may see Digital Authority Partners ads on other sites you visit.Cons of SEM
1. Odds are already stacked against SEM
Let’s be candid. Many people have subconsciously trained themselves to ignore “paid results” entirely when browsing the web or searching on Google. It’s been that way for a while now, and most people often tend to ignore sponsored ads. In fact, a recent Google survey revealed that a whopping 85 percent of online users claim to ignore sponsored listings when searching via Google. So, as a SEM marketer, odds are already stacked against you.2. You get what you pay for
In the world of SEM marketing, you really have to pay to get good results. Get this: the average pay per click for Google AdWords is $0.58 on the display network while it’s $2.32 on the search results pages. That’s an incredibly steep cost rise. Ideally, the more you pay, the better the results. The competition for keywords has never been more cut-throat. Not sure what to spend on cost per click? Ask a PPC agency for law firms (or the PPC marketing services of your particular field) for an analysis.3. SEM is very expensive & requires specialized resources
SEM is so darn expensive – there’s no question about that. I’d like to reiterate that if we ran SEM campaigns against ‘healthcare marketing’ related search terms and received the same amount of visitors and we currently get organically, it would cost us around $65,000 a month. While well-designed and implemented SEM campaigns can deliver targeted traffic, it is quite expensive. And to add insult to injury, the targeted traffic ends when the campaign ends. In addition, SEM is resource-heavy especially at the beginning of a campaign and unfortunately, SEM ads and resultant traffic will cease and disappear as soon as your campaign ends. That’s a pretty bleak approach for an upcoming brand or a small business trying to find its footing in the digital space.SEO vs SEM summary – which is the right search strategy for you?
Final Thoughts on SEO vs SEM
SEO helps you stay ahead of or shut out your competitors. It is also worth noting that SEO does come with its fair share of challenges, too. It can take up to a year to rank at the top of search results, bad SEO agencies can burn through your marketing budget and get you burned, and it is not exactly cheap. SEM, on its side, has a few advantages that you might want to keep in mind when choosing between SEO vs SEM. These include:- Instant targeted traffic – it delivers your desired traffic for the period your SEM campaigns are active.
- It can be a great way to complement your SEO efforts

- People tend to ignore paid search ads
- You have to pay handsomely to get good results
- Targeted traffic ends when the campaign stops
- It’s incredibly expensive especially for startup and small businesses operating on shoestring budgets
- People are warier of biting into ads because of spam and other less than savory advertising tactics.
