Search Engine Marketing (SEM)

Back to Glossary

search engine marketing

SEM (search engine marketing) is considered extremely important as per HubSpot, as 91% of internet users start their online journey with a search engine. 

This means that SEM is one of the most effective ways to reach your target audience. 

So, what if there was a way to ensure your business listing shows up when your customers search for your products? 

Are you curious to check the strategy that puts you in front of your audience precisely when they need you most?

Search Engine Marketing (SEM) can enhance your online presence, drive targeted traffic, and propel your business to new heights. 

Let’s understand how SEM (search engine marketing) can help.

What is SEM (Search Engine Marketing)? 

Search Engine Marketing (SEM) refers to a digital marketing strategy for getting your website noticed on search engines. 

It’s about using paid advertising to make your site pop up search engine result pages; right at the top when someone searches for something related to your product. 

You have probably seen those ads at the top of your Google search results with the words “Sponsored” — that’s SEM in action!

Basically, search engine marketing (SEM) operates in two ways:

  1. Pay-Per-Click (PPC) Ads: You bid on specific keywords, and your ad appears when someone searches for those keywords. You only pay when someone actually clicks on your ad.
  2. Display Ads: Have you ever visited a site and seen an ad related to your recent searches? Those are display ads. They are visual and appear on websites within the search engine’s network, targeting people based on their interests or demographics.

SEM (Search Engine Marketing) is not just about appearing on search results, it’s about being right where your potential customers are ready to click and check you out. 

Why is SEM (Search Engine Marketing) Important?

As visitors keep shifting to online research, consuming content, and shopping for products, guess what’s become necessary for companies? 

Search engine marketing (SEM)! 

It’s now a must-have in online marketing, increasing a company’s reach in the digital world where everyone’s hanging out these days.

When people type their queries into search engines, they are usually on a mission to find something to buy or learn more about. That is when search engines get a signal that someone is ready to buy. 

Unlike social media, where visitors aren’t necessarily on the run to buy, search engines are like the aisles of a shopping mall.

You might have noticed “Sponsored” ads right at the top of your search results. That’s SEM, giving you instant attention. SEM puts you right at the top when someone hits those keywords, unlike the organic search.

SEM is super precise at targeting your audience. You can target people based on what they search for, where they live, their age, and even what they’ve been checking out online. 

With SEM you can get measurable results. You get to peek behind the scenes and see how your ads are doing, how many clicks they are racking up, what each click is costing you, and most importantly if those clicks are turning into sales. 

With SEM you get flexibility in deciding the budget. Doesn’t matter if you are a big-shot company or just starting out; SEM’s got room for everyone. You can tweak it anytime based on how things are going.

SEM and SEO (Search Engine Optimization) go hand in hand. SEO is about ranking organically and takes time. SEO is like taking the steps to the top of a skyscraper; and SEM is taking the elevator.  SEM covers those tough, competitive keywords while your SEO strategy gears up for the search engine marathon. 


Understanding the contrasting yet complementary realms of Search Engine Marketing (SEM) and Search Engine Optimization (SEO) is important. SEM is all about quick attention-grabbing paid tactics, while SEO’s the mastermind behind long-term organic visibility.

How does SEM (Search Engine Marketing) Work?

Search engines use complex algorithms to show you the most fitting results for every search, considering factors like your location and available data. 

Utilizing SEM, you can effectively target fresh customers and boost revenue by positioning your site above organic results on the SERP.

Search Engine Marketing (SEM) typically involves the following steps:

  1. Keywords
  2. Ad Creation
  3. Ad Auction & Placement
  4. Ad Ranking
  5. Cost & Performance Tracking

Let’s see how search engine marketing (SEM) works and what to keep in mind before starting the SEM.


Choosing the right keywords is vital in Search Engine Marketing (SEM) as they determine the timing and placement of your ads in search results.

Understand your Audience

Think like your customers. What would they type into Google when searching for your products or services? Consider their language, queries, and what they are really after.

Keyword Research Tools

You can use different keyword research tools, like Google Keyword Planner, SEMrush, or Ahref, that give details on search volumes, competition, and related terms. 

Relevance and Specificity

When you use specific keywords that your audience might be searching for, then it aligns with the searcher’s intent.  Long-tail keywords (more specific phrases) often yield better-targeted traffic.

Volume vs. Competition

Strike a balance between search volume and competition. You should find that sweet spot with enough traffic but not too much competition. As high-volume keywords may be highly competitive, making it challenging to rank.

Keyword Match Types

There are different types of keyword matches, broad (similar phrases & variation), phrase (exact phrase or variation with additional words), and exact (only the exact phrase). You can play with it to get your ads seen by the right people without wasting money on irrelevant clicks.

Keyword Grouping

Put your keywords into groups that make sense. This way, you can create targeted ads that really speak to what each group is searching for. It’s like arranging your tools in the toolbox for specific tasks!

Competitor Analysis

Sneak a peek at what your competitors are up to. Sites like SpyFu or SEMrush can help you see what keywords they are using, giving you some ideas or content gaps you can fill.

Seasonal and Trending Keywords

Keep an eye on trends and seasons! There are keywords that might soar during specific times or events like Thanksgiving, black Friday, etc. Jumping on those can give your campaigns an extra boost.

Ad Creation

Creating compelling ads is very crucial in search engine marketing (SEM), to attract users to click and engage with your product.

Here are some best practices that you can follow while creating an ad. 

Understanding Ad Components

You have to start strong. Your headline needs to grab attention and include keywords that people might search for.  It’s your first chance to make an impression. 

Keep your description short, sweet, and compelling. Highlight what makes your product or service awesome and why they should consider it. 

Alignment with Searcher Intent

Make sure your ad matches what people are searching for.  You should be able to speak their language and show how you can solve their problem or fulfill their need. 

Remember, different people might be looking for different things. Try customizing your ads to suit different visitors in different stages of their decision-making process.

Keyword Integration

Sprinkle those keywords naturally throughout your ad. It helps your ad show up when someone’s searching for those specific words.

Compelling Call-to-Action (CTA)

Use a clear, strong Call-to-Action (CTA). Tell people what to do next, whether it’s to buy, learn more, or sign up. Your CTA should be compelling enough to encourage users to click. 

Ad Copy Testing and Optimization

Experiment with different versions of your ads to see which ones get the most attention. Keep refining based on what works best.

Ad Creative and Visuals (Display Ads)

If you are using display ads with images or videos, make them eye-catching and relevant to your audience. Visuals can sometimes speak louder than words!

Performance Tracking and Iteration

Watch your ads, and see what’s working and what’s not. Use that data to tweak and improve your ads for better results.

Creating ads for SEM is like crafting a message that speaks directly to your audience, grabbing their attention, showing your value, and inviting them to take the next step. It’s about making that click worth their while!

Ad Auction & Ad Placement

ad auction

The ad auction and where your ads end up on search pages is a big deal in SEM (search engine marketing). As it decides whether your ads shine bright or get lost in the digital jungle. Bagging a good spot means more eyeballs on your ad, more clicks, and potentially more sales.

Ad Auction Process (How is your Ad Rank decided?)

  • When a user enters a search query into a search engine, the ad auction process begins. 
  • Ads that match the searched keywords enter the ad auction. Advertisers set bids and other parameters beforehand to determine when their ad is eligible to compete.
  • The search engine gives a score to figure out which ad deserves the spotlight. It considers bid amounts, ad quality, and how well it fits what the user is looking for.
  • The highest-ranked ads secure top positions on the search engine results page (SERP). The specific placement depends on ad rank, relevance, and other factors, such as ad extensions.

Ad Placement

Do you know how the ads land in specific spots on your search results page? Well, here are the things that decide where those ads go:

  • It’s because of the auction. The higher bids often score better spots. The more an advertiser is willing to pay per click, the better the chance for a top place.
  • Even if someone bids less, their ad might come on top if it’s relevant and impressive. Considering factors like CTR, landing page experience, ad relevance, etc.
  • Including ad extensions (like site links, callouts, or structured snippets) can enhance ad visibility and improve ad rank, influencing placement.
  • Sometimes where you are and what device you are using can affect which ads pop up. 
  • If many advertisers are eyeing the same keywords, it’s a tough fight! Higher competition might mean having to up the bid game for better placement.
  • Your ad’s history matters—how well it’s performed before can influence where it shows up next time. Good past performance can give your ad a boost.

Ads can appear in different spots on search results pages:

Top Position Ads: These usually pop up right above the regular search results, grabbing a lot of attention as they’re the first thing people see.

Side or Bottom Ads: Other ads might hang out on the sides or at the bottom of the search results. They might not get as much attention, but they can still attract clicks.

Ad Ranking

In Search Engine Marketing (SEM), where businesses aim to stand out online, ad ranking comes to its rescue. When your visitors perform their search query, ads show up on that page. Now let’s find out how your ad rank gets calculated.

Ad Rank Formula

Ad Rank = Max. CPC Bid × Quality Score


Max. CPC Bid is the maximum cost-per-click bid set by the advertiser.

Quality Score is a metric that includes various factors like ad relevance, expected click-through rate, and landing page experience. It’s essentially a measure of the quality and relevance of your ad.

The higher your overall score, the better your chance for a top spot.

Quality Score Impact

Sometimes, a higher quality score can outweigh a competitor’s higher bid. Even if your bid’s a bit lower than your competitor’s, your ad grabs a higher spot. 

Dynamic Ad Ranking

Every time users hit that search button, ad ranks reshuffle based on the specific search, like where you are, what you are using to search, and what you are searching for. Ad rank gets re-calculated for each search. 

Cost & Performance Tracking

In the last part, we will discuss what are the metrics you should keep track of for your ads to be more effective and efficient.

Cost Tracking

When someone clicks on your ad, that’s your Cost-per-Click (CPC). Keeping track of CPC  will help you understand the actual cost you pay for each click. 

Keeping track of Cost-per-Acquisition (CPA) would help you know the amount you spend for each conversion. 

Keeping an eye on the overall budget spent on your campaigns is like watching your spending limit. It’s crucial to make sure you’re not burning through cash faster than planned. Also, tweaking bids based on what’s working or not can be a real money-saver!

Performance Tracking 

Click-through rate (CTR) tells you how many people click on your ad after seeing it. A high CTR means visitors are digging your ad. 

Conversion rate (CR) shows how many visitors completed a desired action after clicking an ad, such as making a purchase or filling out a form. It can help you evaluate campaign effectiveness.

Return on Investment (ROI) calculates the profitability of SEM campaigns. It tells you if your ads are making more money than they cost you. Good ROI means your ads are doing their job well.

Tracking your ad positions on SERPs provides insights into visibility and performance. Higher positions usually yield better CTR but may have higher costs.

Keeping tabs on your ad’s quality score helps you understand if it’s relevant and hitting the expected CTR. Higher scores often mean better ad placement and lower costs.

SEM (Search Engine Marketing) ensures your business appears exactly when customers are searching for you. It’s about grabbing attention instantly, driving targeted traffic, and getting measurable results.

SEM success also depends on continuous optimization, regularly tweaking your ads, experimenting with different keywords, and analyzing data to refine your strategy. 

Landing pages matter! Your ad might be fantastic, but if the page users land on isn’t relevant or compelling, it could affect your results. Ensuring a seamless transition from ad to landing page increases the chances of converting clicks into sales or inquiries. 

Remember, Search Engine Marketing (SEM) isn’t a set-it-and-forget-it deal. It’s an ongoing process of monitoring, adjusting, and fine-tuning to keep your business front and center when customers are searching.
