What is SEM

Getting your Trinity Audio player ready...

Have you searched for something on Google today? I bet you have. Now think about it: did your brand appear in the top positions of that search? If not, you could be leaving money on the table — and that’s where SEM comes in.

With it, you not only appear at the top of the page, but you appear at the exact moment when someone is looking for what you offer.

What is SEM, anyway?

SEM is the acronym for Search Engine Marketing — or, in plain English, Search Engine Marketing. This is a set of paid and organic strategies that aim to increase the visibility of your website on search engine results pages, such as Google, Bing and Yahoo.

In other words, SEM is everything you do to appear better — and more often — in search engines. And yes, this includes both paid advertising and SEO strategies.

“SEM stands for Search Engine Marketing, a strategy that combines paid advertising and organic optimization to increase a website’s visibility in search engines.”

WITHOUT vs SEO: Different brothers with the same goal

This is a common question: “Is SEM the same thing as SEO?”

The answer is no, but they go hand in hand. Think of it this way: SEM is the umbrella, and SEO is under it. So SEM encompasses all actions to gain visibility in search engines, and SEO is the organic part of that.

Sponsored links (such as those from Google Ads) are the paid part of SEM. In other words:

• SEM = SEO + sponsored links
• SEO ≠ SEM (alone)

Sponsored Links: The Paid Side of SEM

Sponsored links are those advertisements that appear prominently on the SERP (Search Engine Results Page). The most famous of these is Google Ads.

You only pay when someone clicks (CPC – Cost Per Click) or when your ad is displayed (CPM – Cost Per Thousand Impressions). This way, it is a way to attract immediate traffic, unlike SEO, which is a long-term construction.

But be careful: paid traffic doesn’t scale infinitely. There comes a point when ROI starts to drop, and that’s when SEO shines.

How Google Ads works within SEM

Google Ads is the heart of most SEM strategies. With it, you can:

• Create campaigns by key words;
• Segment audiences based on interests, location, and behavior;
• Monitor performance in real time.

You set how much you want to pay per click and Google displays your ad based on the keyword auction. It's a smart system, but it requires constant planning and analysis.

Keyword Strategies in SEM

It’s not enough to just choose any keyword and expect miracles. You need to have a well-defined strategy that includes:

• Head tail words: more generic, higher volume, higher competition.
• Words long tail: more specific, lower volume, but higher conversion rate.

It is essential to think about the search intent: what does the person really want when typing that into Google?

“Keywords in SEM must consider search volume, competition and the objective of the search, balancing generic (head tail) and specific (long tail) terms.”

The role of SEO within SEM

If paid traffic brings you immediate visibility, SEO guarantees it consistent and sustainable presence over time.

SEO is divided into:

• On-page: optimizations within the website (content, titles, meta descriptions, HTML structure).
• Off-page: backlinks, mentions and domain authority.

In a good SEM strategy, the SEO sets the stage for paid traffic to be more efficient — and cheaper.

Blogs, content and SEM: the visibility triad

There's no getting around it: content is the soul of SEM. One well structured blog helps to rank organically (SEO), feeds paid campaigns and improves conversion rate.

A well-positioned article can:

• Reduce your cost per click;
• Increase the time spent on the site;
• Create authority in the market.

So have a active blog and aligned with your SEM strategy.

Google, Bing, Yahoo: where to do SEM?

Although Google dominates with 93% from searches in Brazil, Bing and Yahoo have their audiences — especially outside the country. And the best part? The cost per click is usually much lower.

In other words, if you want to stand out while spending less, these search engines can be an unexplored gold mine.

To create a killer SEM strategy, follow these steps:

1. Keyword research;
2. Campaign creation and segmentation;
3. Website optimization (SEO);
4. Creation of relevant content;
