In the world of digital marketing, most of us have probably heard the terms Search Engine Optimization (SEO) and Search Engine Marketing (SEM). Both of these marketing strategies focus on search engine platforms like Google.

Before we explore the differences between these two marketing strategies and how they work, let's break them down one by one.

What is Search Engine Optimization (SEO)?

So, what is SEO? SEO, or Search Engine Optimization is a digital marketing strategy that focuses on improving the quality of a website with the goal of achieving a high ranking in search engines.

The higher a website's ranking on a search engine results page (SERP), the more likely users are to choose or click on that website.

Is Google the only search engine to optimize? The answer is no. There are other search engines such as Bing, Yahoo, Yandex, and Baidu. However, according to statistics, more than 90% of internet users worldwide use Google as their primary search engine, far surpassing other search engines. This is the main reason why Google should be prioritized.

What Is Search Engine Marketing (SEM)?

After understanding the definition of SEO, let's talk about SEM. What is SEM? SEM or Search Engine Marketing is a digital marketing strategy that uses paid advertising to improve a website's ranking in search engines.

SEM works by displaying website ads in search results for targeted keywords. The use of SEM can usually be seen in the top search results with the label "Ad" or "Sponsored".

To run a SEM strategy or advertise on Google, users can open the Google Ads page. There are many features provided to run an ad. One of the features is the keyword planner, which is useful for finding out what keywords are trending and also for viewing ad statistics.

Benefit of SEO

Here are some benefits of using SEO strategy:

1. Increase Visibility

By implementing SEO strategies correctly, websites will have a greater chance of appearing at the top of search results. This can increase the visibility of websites and enable users to learn more about the products or services offered.

2. Increase Brand Awareness

SEO can increase brand awareness for businesses by making their products or services widely known to the public. This is because business websites that appear at the top of search results will be seen more often by audiences.

3. Long-term Marketing Strategy

SEO is an ongoing process and its results can last for a long time. Once you have implemented the right SEO strategies, your website will continue to rank well in search results as long as the content and structure of the website remain relevant.

4. Increase Sales

By dominating online search, websites will get more unique visitors and increase conversion opportunities. This is because users who find your site through search are more likely to have specific interests or needs that can be met by your products or services.

Benefit of SEM

After understanding the benefits of SEO for a website, here are the benefits offered by SEM:

1. Quick Result

Unlike SEO, which takes time to see the results of optimization, using SEM strategies can make websites appear in the top search results immediately after their ads are launched. This can help businesses reach more potential customers and increase their sales or conversions.

2.  Increase Conversion Rate

Ads that target keywords with transactional search intent can increase the conversion rate of websites. This is because website visitors with this search intent already have a desire to purchase the products or services offered.

3. Adjustable Budget

SEM advertising budgets can be adjusted to the business budget. In the beginning, you can use a small budget to conduct A/B testing. If the ads are performing well, you can increase the budget to get more optimal results.

4. Measurable Result

SEM is an effective way to promote a business. Business owners can see exactly how many people saw their ads, the number of ad clicks, and conversions. This information can help business owners measure the success of their SEM strategies and make necessary adjustments.

Differences Between SEO and SEM

After we all know the definitions and benefits of each strategy, let's explore the differences based on the following factors:

1. Time Required

According to some sources, SEO can take at least 3 to 6 months to have results, but in some cases, it can take longer, up to 12 months or even years.

SEM, on the other hand, does not require much time. Google has a bidding system in Google Ads to run advertising campaigns. If an ad wins the bidding system and has relevant settings, Google can instantly give the ad a top ranking.

2. Audience Targeting

SEO is a marketing strategy that is suitable for businesses that aim to reach everyone who is looking for their products or services. Meanwhile, SEM is suitable for businesses that want to reach a specific audience such as based on location, age, or interests.

3. Cost

Many people are attracted to the SEO strategy because it can generate traffic for free. It means that you do not need to pay any fees when someone clicks on your website in the search results.

On the other hand,, advertisers must pay a certain amount of money for SEM when their website is found in a search engine and a user clicks on it .

4. Duration

SEO is very suitable for long-term business strategies. The reason is because SEO produces lasting results that are based on the quality of the content and website. When you create high-quality and relevant content for your audience, search engines will continue to recommend it in search results.

SEM, on the other hand, depends on the duration of the advertising campaign. When an advertising campaign is finished, the website being promoted will also no longer be displayed by Google.

These differences have been summarized in a table below:

Consideration for Use

If you are a business owner and run a website, you may want to consider using both of these strategies. Here are some factors or considerations that you can use as a reference:

1. Consideration of Using SEO

  • Time Needed

SEO strategies require months to generate organic traffic for leads or sales. Make sure you have plenty of time to optimize for this.

  • Build Reputation

SEO strategies can be used to reach a wide range of content, such as informational or transactional content. Therefore, this content can be used to communicate the benefits of your products or services and other interesting information.

  • Long-term Investment

SEO has good long-term benefits for the sustainability of digital marketing strategies. Once the SEO strategy is right, the optimized website pages will continue to rank at the top for a long period.

2. Consideration of Using SEM

  • Quick Result

SEM is a great option if you want to generate website traffic and online sales quickly.

  • Consistent Budget

If you have a budget that you can afford to spend, then SEM is a good fit. The budget you spend can be used to generate sales, especially if your budget is consistently set for a certain period, such as every month or every week.

3. Consideration of Using SEO and SEM

  • Search Engine Domination

You can use both of these strategies simultaneously, which is called search engine domination. This method is very suitable if you want to make your brand stand out and dominate the online market.

However, if you run both of these methods, you will have to spend more time and money than running just one strategy.

  • Remarketing Campaign

A remarketing campaign is a way to reach back to audiences who have visited your website. By running a this campaign, you can target audiences who did not purchase your products or services.

Conclusion

SEO and SEM are two digital marketing strategies that have their own advantages and disadvantages. The right strategy depends on the needs and goals of your business.

If you want to get quick results and target a specific audience, then SEM is the right choice. However, if you want to get lasting results and reach everyone, then SEO is the right choice.
