When Google launched AdWords in 2000, it changed everything for marketers.
Up until that point, brands spent millions convincing customers to want their products. With AdWords’ search-based ads, they no longer had to—they could suddenly serve their ads to peoplealready searching for products like theirs.
If you sold tennis shoes, you could simply serve ads to people looking for tennis shoes, and only pay when someone clicked your ad. Search engine marketing (SEM) was born.
SEM has come a long way since the year 2000 (and Google AdWords is now Google Ads), but the fundamentals are the same. It remains an incredible online marketing strategy for many brands.

What is search engine marketing?
Like many terms in数字营销ob欧宝娱乐app下载地址, the term search engine marketing (can be a little confusing to the uninitiated. Put simply, SEM refers to paying for advertising on search engines.
SEM is important because online shopping continues togrow year over year. The majority of new visitors will find you by searching for a query on a search engine.
When your target audience searches for commercial keywords, you’re more likely to get your product in front of them. Unlike social media where people are more in the discovery phase, these shoppers are ready to buy.
What is SEM vs. SEO?
SEM and SEO often get confused with each other. It’s important to understand the difference:
- Search engine marketing (SEM)is a type of online marketing that involves the promotion of websites by increasing their visibility in search engine results pages (SERPs) through the use of paid advertising.
- Search engine optimization (SEO)is a subset of search engine marketing where the focus is on optimizing a website or webpage to improve its organic visibility in search engine results pages. SEO involves optimizing the content, technical aspects, and backlinks of a website to improve its search engine rankings.
The most important distinction is that SEM is different fromsearch engine optimization.There are two ways to reach your customers in search engines:
- SEM refers to running Google Ads or ads on another search engine, like Bing or Yahoo).
- SEO refers to updating your website to show up in Google search results naturally, or “organically”—meaning you didn’t pay for the placement.
SEM可以展示您的广告结果立即,因为你are essentially paying for placement on the Google search results page. SEO efforts, by contrast, can take months or years before you show up in your targeted searches.
It is a common misconception that SEO and SEM overlap each other. Running SEM campaigns has no bearing on your organic search results, and vice versa.
The basics of marketing on search engines
Search engine marketing is based on a few key principles:
Search engine results page (SERP)
This is the page of search results that shows up when you Google something. The SERP includes both the paid (SEM) and organic (SEO) search results.
Keywords (KWs)
Keyword research tells you what search terms (what someone actually types into Google) should trigger your ads.
In SEM, keywords can be highly specificexact matchkeywords (show my ad only if someone types “athletic green size 12 tennis shoes”) or more generalbroad matchkeywords (show my ad when someone types any phrase that includes “tennis shoes”).
While “regular” keywords target search terms,negative keywordsexclude search terms. For example, many advertisers addfreeto their ad campaigns as a negative keyword, which would mean their ads wouldn’t show up on searches for “free tennis shoes.”
Pay per click (PPC)
Pay per click is the foundational business model for most search ads. This was part of Google’s compellingunique value propositionwhen launching AdWords—you only pay when someone clicks your ad.
Modern SEM campaigns aren’t always billed by cost per click, but it remains an important industry concept, and some people still refer to search engine marketing as PPC advertising or PPC marketing.
How does search engine marketing work?
Google’s AdWords product actually createdtworevolutions in marketing:search intent targetingandauction-based advertising. To understand how SEM works, you need to understand these two frameworks:
Search intent targeting
When marketers build SEM campaigns, their starting point issearch intent. This means defining two important things:
- What are our potential customers/users searching for?
- How close are they to buying something?
For example, a search such as “fun ways to exercise outside” indicates that a user might eventually buy tennis shoes but isn’t necessarily in the market for them at the time of their search.
Thesearch intenthere is to exercise and potentially use tennis shoes, but not to buy them. However, a search such as “best tennis shoes for narrow feet size 10” indicates that the user is much closer to making a purchase, because of the specificity of their search. This is considered a “high search intent” search for buying tennis shoes.
SEM marketers typically build their campaigns to target the highest possible search intents by creating ad groups targeting either “branded” terms (their own brand or their competitors’, such as “Nike tennis shoes”) or highly specific “unbranded” (sometimes called “non-branded”) searches for their products or services (e.g., “athletic tennis shoes”).
Auction-based advertising
Google’s second revolution was its auction-based bidding system. In regular advertising, the company sets a rate card for its ad space (for example, $10,000 to run a 30-second ad on a TV show), and advertisers buy that ad space.
With Google, there are billions of different ad spaces (Google processes more thanfive billion searches per day), each with its own intent and number of users searching it per month, so it couldn’t just set a single rate for a search result.
Instead, Google created an auction-based system. Every single time a search happens in Google, it runs a real-time ad auction and “awards” each ad space on that search to an advertiser based on the auction results.
Unlike a regular auction, it’s not just awarded to the highest bidder, however. It’s awarded to a combination of the highest per-click bid and the ad rank, or its “Quality Score,” Google’s proprietary metric for evaluating ad quality (other search engines have similar metrics).
An ad’s Quality Score is determined by a variety offactors:
- Estimated click-through rate (CTR):Will the user click the ad when shown?
- Relevance:How closely does your ad match the intent of the specific search?
- Ad landing page:How useful is your landing page once the user clicks through your ad?
In short, Google’s algorithm judges the “fit” your ad has for the user, like a painting auctioneer deciding to award the painting to the bidder in whose home they think it will look best in. Much of the job of an SEM marketer is to achieve a high Quality Score (and low cost-per-click) on their high-intent keywords, by creating compelling ad copy and landing pages that match the keywords.

When is SEM right for your business?
There are two factors to help you understand if SEM is right for your business:
- When you’ve found your product/market/messaging fit.Your Quality Score determines how much you pay per click. A good score depends on ad copy that resonates with your target searchers. To be successful with SEM, you need to understandwhoyour market is (product/market fit) andwhatresonates with them (market/messaging fit). If you haven’t accurately determined this, Google may assign you a low Quality Score, meaning you will be charged more for ads, and it will be difficult to succeed.
- When you are capturing a category instead of creating it.SEM relies on high-intent searches, which means people need to be searching for your type of product or service. If you sell tennis shoes, that’s no problem—in the US, there are 135,000 searches for “tennis shoes” every month. If your product is creating a new category, such as a hybrid tennis shoe/cozy slipper, people aren’t yet searching for it, so it will be much more difficult to determine specific keywords to target.
You can create category awareness through other types of marketing, then run search engine marketing campaigns once the market is more aware of your product. You can do your own research on search queries in your industry using theGoogle Ads Keyword Planner.
