SEM also has the following disadvantages:
SEM relies on keywords (sentences entered by users into search engines) that can be used to create relevant content and ads designed to capture your target audience.
Using the right keywords in the right places is essential for your ads to appear in top positions on search results pages. 🎯
Your chances of success are higher if you ensure that your content aligns with search intent - that is, the reason behind a user's specific query.
SEA (Search Engine Advertising) aims to improve your website's visibility in search engines through paid ads. This involves writing relevant text, including attractive images, choosing a targeted audience, and defining keywords to trigger ads.
Paid search often delivers fast results. However, once you stop your ad campaigns, visibility and traffic also come to a halt.
Google's search ads are displayed in the results when users enter specific keywords in the search bar.
Google's shopping ads are displayed when an internet user searches for a specific product. 🛒
They can appear in SERPs, the Google Shopping tab, Google Images, Maps, etc.

Google Ads uses a bidding system to determine which ads are displayed and in what order.
According to Google, there are 6 main factors to consider:
A well-structured Google Ads account groups ads by theme to allow for strategic bidding.
Let's discover how an account is structured:
After defining your ad groups, you must target specific keyword groups that match with your audience for each of them.
The success of SEM strategies relies on the identification and purchase of ad space on the most effective keywords and long-tail expressions related to a product or service.
As already said, the definition of these terms relies on the internet user intention called "searcher intention". This refers to the action a user is willing to start when they search a specific keyword.
🔨 Several tools can help you find the best requests:
For Google, Bing and Yahoo, all ads must go through a bidding proccess that takes place each time a user performs a search.
For example, Google's ad bidding system uses several factors (described above) to determine which ad appears at the top of the page, including the quality score obtained in Google Ads.
The SEM campaign with the highest budget doesn't always get the top position. This depends on the quality of the content. In fact, some of the factors that influence organic rankings - such as trust signals and web traffic - are also taken into account in Google's ad auctions.
In general, search engine ad bidding take follows 4 steps:
1️⃣ Bid. To launch an SEM campaign, you define the maximim amount you are willing to pay for a click on a keyword.
2️⃣ Quality score. Platforms like Google Ads evaluate the ad and its linked website based factors such as the keywords used, the website's user experience, the usefulness of the landing page content, and available ad assets like phone numbers or additional links. Google also sets quality thresholds that ads must meet to reach certain positions.
3️⃣ Contextual factors. Because auctions occur every time a search is made, search engines like Google and Bing also consider contextual data to determine ad placement. This includes the user's physical location, their search history, the time of day, the device used, and even other ads and organic results on the page.
4️⃣ Ad rank. An ad rank is then assigned to the advertiser, based on all the criteria considered by Google. It's important to note that the top position does not necessarily go to the highest bidder.
To create a successful SEM campaign strategy, professionals use different strategies and tools such as:
1️⃣ Keyword research. As seen before, the first step in an SEM campaign is identifying the most effective keywords for which you want to buy ad placements. To do this, we can use dedicated tools. It's also helpful to analyze competitor's ads and use geomarketing insights about your target audience.
2️⃣ Budget. Define a budget for your ad campaign and set a maximum bid amount.
3️⃣ Ad groups. A company that advertises multiple products or services can create several ad groups - meaning several ads within a campaign that target similar audiences. This approach is more cost-effective than assigning one keyword per ad, which can be expensive.
4️⃣ Create and test a landing page. Each ad must lead to a landing page featuring the relevant product or service. You will need to optimize this page appropriately. A/B tests can help improve metrics such as revenue per page and the average order value.
5️⃣ Create the ad. The next step is to create an ad for each keyword-based ad group.
6️⃣ Submit the bid. Once the ad is ready, it enters the search engine auction.
7️⃣ Monitor the campaign. The final step is to track your campaign's performance using analytics tools like Google Analytics. These tools allow you to monitor keyword performance and make adjustments. 📈
Search engine marketing is one of the most effective strategies to reach potential customers.
