How do you define SEO and SEA, and how do these two online strategies differ?
What is SEO?
What is SEA?
The abbreviation SEA stands for ” Search Engine Advertising.” It refers to paid ads that can be placed on various search engines (such as Google, Bing, or Yahoo) to appear near the top of search results.
Such search engine results are always labeled as ads.
What is the difference between SEO and SEA?
The difference between SEO and SEA is that search engine advertising (SEA) is a paid service. This means that ads are displayed for specific search terms, and the advertiser pays for each click on their ad. Depending on the search term (keyword) for which the ad is placed, the costs can vary significantly. In this context, defined, time-limited campaigns make the most sense.
With search engine optimization (SEO), on the other hand, costs arise in a different way: through your own time spent on the ongoing optimization of the site, writing search engine-optimized content, or continuously managing social media activities. This requires a significant amount of work and, of course, knowledge of how best to influence search results. SEO is a long-term investment—for example, in high-quality content. Once created, it remains effective for a long time and only needs to be updated.
On-Page SEO Measures
Specifically, a distinction is made between on-page and off-page measures. On-page measures encompass all activities that can be carried out directly on the website. Off-page optimization encompasses all activities that take place outside of one’s own website, such as building external links.
Components of On-Page Optimization
- User-friendly and keyword-optimized content
- Adding a Title and Meta Description to Individual Pages
- Adding User-Friendly URLs
- Adding a Sitemap
- User-friendly structure with clearly defined headings
- Reduce load times: for example, by using compressed images and caching
- Internal Links
Components of Off-Page Optimization
Search Engine Marketing as an Integral Part of Corporate Strategy
More and more people are searching online for a product or service. As a result, the purchasing process increasingly begins with a search query—for example, on Google.
Approximately 95% of search queries in Austria are conducted via the Google search engine, which means that Google—and thus Google Ads —is the most relevant platform for search engine marketing. The remaining search queries are generated via Bing and Yahoo!. Of course, there are also opportunities to place ads on these platforms.
Given these impressive figures, it’s no surprise that so many companies invest in search engine marketing to secure the top spots in Google’s rankings. After the first three results, relevance and click-through rates drop dramatically. While the result in the No. 1 spot in search engine rankings receives about one in every three clicks, the sixth result is clicked on by only one in every twenty users.
As a result, 84% of German companies view search engine optimization as profitable or even very profitable. (Source: Statista)
What are the benefits of search engine marketing?
SEO and SEA are …
1. measurable
One of the biggest advantages of using search engine advertising is its measurability. You can accurately measure how successful your ad was, how much money was spent on it, and how many clicks it received.
This allows you to accurately calculate your cost per lead and your return on investment, and thus determine whether your ad is profitable and whether you’ve achieved your goal. This also makes it easier to compare the results with other advertising efforts. In addition, you can track which keywords users used to start their search queries and thus gain a better understanding of your target audience.
2. controllable
Search engine advertising can be tailored precisely to your target audience. It can be customized based on specific demographic characteristics such as age or gender, displayed only on certain devices, or restricted to specific geographic locations. In addition, you can set your budget precisely and spend only what you actually have available.
You can set your budget precisely for a specific time period or even on a daily basis. This gives you full control over costs and flexibility, since ads can be paused and reactivated at any time. Plus, you don’t have to wait long to see results—as soon as the ad is approved, it goes “live” and is delivered to your target audience.
3. flexible
Measuring success and conducting tests proves to be extremely difficult for many advertising campaigns. It’s often impossible to say exactly what resonates with the target audience. With search engine marketing, you have the opportunity to test a wide variety of ad variations and measure their effectiveness. Ultimately, only the ad that resonates best with potential customers is served to them.
4. relevant
Because the target audience for search engine advertising can be defined quite precisely and ads are delivered only to people who have searched for the keywords you’ve defined, there is very little wasted reach with SEA. The traffic coming to your website is usually relevant traffic as well, since visitors have, after all, searched directly and specifically for your keywords.
