[03:03] back to SEO and continue understanding how it works. Which metric shows the percentage of impressions that resulted in clicks? Is it A, CPC, B, CTR, C, CPA,

[03:15] answers in the comments below. Search SEM, is the process of promoting a business through paid advertisements that appear when people search for relevant services or information on

[03:28] understand this, suppose someone searches for online data analytics course. That search tells us something really important. The person is actively analytics course. A training provider

[03:41] can use a search advertising platform such as Google Ads to compete for visibility when searches like this occur. And this makes SEM highly intent-driven. So, instead of showing an advertisement to everybody, advertisers

[03:54] indicate that they may be interested in a particular solution. A typical SEM journey can be understood as search, advertisement, landing page, and action. registration, phone call, form submission, subscription, or another

[04:09] conversion defined by the business. SEM therefore involves much more than simply purchasing advertisements. Advertisers need to research search behavior, select targeting strategies, create relevant advertisements, decide budgets and

[04:22] bidding strategies. They also design useful landing pages, track conversions, and continually improve performance. Search advertising also exists system, and Google states that the advertisers cannot pay to receive the

[04:36] organic search rankings. The goal of SEM is therefore paid visibility combined with measurable business results. Now, let's move on to how paid search works. Paid search begins with the search query. A user goes to a search engine

[04:48] and type something that they want to find. For example, someone might search for best project management certifications. Now, Google can identify advertisements that may be eligible to appear for that search. This process

[05:00] happens through an automated advertising auction. It doesn't mean that every automatically gets an advertisement displayed. Eligible advertisements evaluates several factors before deciding which ads can appear and their

[05:14] positions. Now, the process can be simplified as search query, ad auction, advertisement, click, landing page, and conversion. Advertisers commonly associate search campaigns with the pay-per-click model, meaning that a

[05:28] charge can occur when someone clicks the advertisement. However, the click itself should not be treated as the final goal. Suppose an advertisement receives 2,000 clicks, but only one visitor purchases the product, the campaign may generate

[05:40] valuable enough to justify the advertising cost. And that is why successful SEM focuses on what happens after the click. The landing page needs to match what the user searched for and what the advertisement promised. Now,

[05:53] that allows marketers to understand whether the visitors generated leads, purchases, sign-up calls, or other useful outcomes. Search advertising therefore connects users' intent, advertising visibility, website

[06:07] results. Now, let's draw comparison between the following three. SEO, SEM, and PPC are terms that are often used together, but they describe different parts of search marketing. SEO or search engine optimization focuses on improving

[06:20] a website so that it can earn visibility in an unpaid or organic search results. technical improvements, website structure, links, and other optimization activities. SEM, in the context of paid search, is focused on advertising

[06:35] platforms to gain paid visibility while relevant searches occur. PPC or pay-per-click is a price model which is an advertiser paying when someone clicks an advertisement. Therefore, a Google search campaign can be both an SEM

[06:48] activity and a PPC campaign. Now, the easiest way to understand the difference is through visibility and timing. SEO focuses on earning organic visibility over time, while SEM allows businesses to compete for paid visibility around

[07:01] selected customer searches. However, spending more money does not automatically guarantee the top position. Search advertisements participate in an auction where factors beyond the advertisers' bid can affect

[07:13] eligibility and placement. And this is important because paid search is not simply a system where the highest spender always wins. SEO and SEM can also work together. SEO can support long-term organic visibility, while SEM

[07:26] can support immediate goals such as lead generation, product launches, sales campaigns, or highly competitive commercial searches. Now, both understanding what users are searching for and what they expect to find. Now,

[07:39] let's move ahead with keywords and search intent. Now, keywords are one of the foundations of search advertising because they help advertisers indicate which types of searches are relevant to their businesses. Now, suppose a company

[07:51] offers a digital marketing program. A potential keyword could include digital marketing courses, online marketing certification, or learn digital marketing. But, successful keyword search doesn't mean simply finding

[08:03] phrases with large search volumes. Marketers also need to understand search intent, which means understanding what the user is actually trying to achieve. Compare three searches: What is digital marketing? Best digital marketing

[08:15] courses? And enroll in digital marketing certification. Now, the topic is similar, but the intention is very different. The first user appears to be learning, the second may be comparing options, and the third shows stronger

[08:27] intent to take action. Now, advertisers can use this information when deciding which searches deserve more budget, what advertisement should appear, and which landing page should be used. Modern keyword matching is also more flexible

[08:39] than simple word-for-word matching. Google explains that keyword match types determine how closely a keyword needs to match a user search before an advertisement can be considered for the auction. AI-powered search tools are

[08:51] also taking this further by interpreting contextual signals and identify relevant searches that may not exactly match the advertisers' original wording. Effective keyword strategy therefore combines relevance, user intent, business value,

[09:03] keyword match types and negative keywords. After choosing keywords, advertisers need to control how closely a user's search query should relate to those keywords. Now, Google Ads provides different keyword match types for this

[09:17] purpose. Broad match gives advertisers the widest potential reach and may allow related to the keyword's meaning. Now, targets search that includes the meaning of the keyword, while still allowing

[09:31] some variation. Exact match also gives advertisers tighter control by focusing on searches that share the same meaning or intent as the selected keyword. match as determining how closely a keyword needs to match a user's query

[09:45] in the auction. So, now another So, a negative keyword tells the advertising system that certain searches should be excluded. For example, imagine a company selling pay project management

[09:58] software. It targets project management software, but it starts receiving traffic from people searching for free project management software. Now, if the it may exclude the word free to reduce irrelevant traffic. So, this illustrates

[10:11] an important principle in SEM. More traffic is not automatically better. Advertisers need relevant traffic. Match types help expand or control reach while negative keywords help remove searches that are unlikely to produce useful

[10:25] business outcomes. Now, let's move on with Google Ads campaign structure. A structure so that the right advertisements can appear for the right searches. A simplified Google Ads hierarchy can be understood as account,

[10:38] campaign, ad groups, keywords, and ads followed by landing pages. Now, the campaign sits at a higher level and contains major settings such as budget, campaign objective, bidding strategy, geographic targeting, and other campaign

[10:51] level controls. Now, inside each campaign are ad groups. Ad groups help advertisements around a particular product, service, or theme. For example, imagine a training company running a campaign for a digital marketing course.

[11:05] So, instead of every marketing topic into one ad group, it might create separate groups for SEO courses, Google Ads courses, and social media marketing. Now, each ad group could then contain closely related keywords and

[11:17] SEO certification, the advertisement could ideally mention SEO rather than course offered by company. After clicking the advertisement, the user your page. Now, this creates what we call a relevance chain. This includes

[11:34] search intent, keyword advertisement, landing page, and conversion. Now, clear structure makes the campaign reporting easier, improve messaging consistency, allows better testing, and gives the advertiser more control when optimizing

[11:46] different areas of campaign performance. Ad auction, ad rank, and quality. One of the biggest misconceptions about search advertising is that the advertiser with the highest bid automatically receives the highest advertising position. Search

[11:59] advertising works through a more complex auction. Every time an eligible search advertising opportunity occurs, Google evaluates multiple signals to determine whether an advertisement can appear and where it may be positioned. Now, the

[12:11] advertiser's bid is important, but it's only one part of the process. This is where the concept of ad rank becomes important. Advertisers need to think about both how much they are willing to bid and the overall quality and the

[12:23] provide. Now, Google also provides a diagnostic metric called quality score. Now, quality score can help advertisers identify whether the advertisements and Google says that its quality score components include expected

[12:38] click-through rate, ad relevance, and landing page. An important point is that quality score should be treated as a diagnostic tool rather than a number that marketers simply try to maximize. Say, for example, weak ad relevance may

[12:50] indicate that the advertisement doesn't closely match the keyword. A weak that visitors are not finding what they expected after clicking. Now, the bigger lesson is simple. Successful search advertising depends not only on on how

[13:03] much you bid, but also on how effectively the advertisement satisfy the user search. Now, let's move on to search ads and landing pages. Once the searches, the next challenge is convincing the user that the

[13:16] solution. An effective search advertisement should communicate these three things quickly. What is being offered, why it's relevant, and what should the user do next. Suppose someone searches for data analyst certification

[13:29] online. An advertisement saying only online courses available provides very little context. A more relevant search such as data analyst certification learn online build analytics skills connects much more clearly with the user search.

[13:42] beginning of the experience. After clicking, the user arrives on the continue the same message. If the advertisement promises a data analyst certification but sends visitors to a generic home page containing dozens of

[13:56] Now, the landing page should make the next action simple and clear. It should contain a strong value proposition, relevant information, useful supporting details, trust signals, and a visible call to action. The full journey should

[14:10] therefore remain consistent. Search query, relevant advertisement, relevant landing page, and clear action. Now, this consistency helps improve the user's experience and gives campaigns a better chance of turning clicks into an

[14:22] actual business result. In SEM, generating attention is useful, but to action is what ultimately creates value. Now, let's move on to bidding, Bidding determines how an advertiser competes during search auctions, while

[14:37] plans to spend. In a traditional campaign, marketers may think in terms of how much they're willing to pay for individual clicks, but modern Google Ads increasingly use automated and AI-assisted bidding strategies based on

[14:50] business objectives. Now, an advertiser may focus on maximizing clicks when the conversions when the goal is to generate many actions as possible, target CPA when the business has a preferred cost per acquisition, or a target ROAS when

[15:04] the revenue efficiency is a priority. But the correct strategy depends on the campaign objective and the quality of conversion data available. Search increasingly AI-driven. So, Google announced new bidding and budget

[15:17] capabilities at Google Marketing Live 2026, including journey-aware bidding designing to help the system understand lead quality beyond the initial conversion, and demand led pacing, which can adjust spending around changing

[15:29] consumer demand while working within budget goals. AI max for search also matching, text customization, and landing page selection. Now, this does not remove the marketer from the process. Automation still needs good

[15:43] objectives, reliable conversion tracking, strong creative inputs, appropriate budgets, useful landing pages, and accurate business data. Now, the marketer's role is increasingly shifting from adjusting every individual

[15:55] bid to guiding the system with better goals and better information. Now, let's move on to measuring and optimizing SEM performance. Launching a search engine campaign is only the beginning. Marketers then need to measure what

[16:07] happened and decide what needs to improve. Impressions show how many times show how many times users selected the advertisement. CTR or click-through rate measures the percentage of impressions that produce clicks, and can be

[16:20] calculated as clicks divided by impressions into 100. CPC or cost per click tells us the average amount spent for each click. But, clicks don't just necessarily represent business success, and that is why advertisers track

[16:32] conversions such as purchases, registrations, phone call subscriptions, downloads, or qualified leads. From there, we can calculate conversion rate, which is conversions divided by clicks into 100. Another important metric is

[16:44] CPA or cost per acquisition, which can be calculated as advertising cost divided by conversions. Revenue focused campaigns may also measure ROAS or return on ad spend using revenue attributed to advertising divided by

[16:56] advertising spend. Now, these metrics help marketers diagnose problems. If any but very few clicks, the keyword targeting or advertisement may need click-through rates but very few

[17:10] conversions, the landing page, audience quality, or offer may be the problem. If conversions are increasing but CPA remains too high, Bidding or targeting may need adjustment. SEM optimization is therefore an ongoing cycle. Measure,

[17:22] analyze, improve, test, measure again. Strong search campaigns are rarely created once and left unchanged. They improve through continuous analysis And with that, we have reached the end of this session on search engine

[17:35] marketing. The key takeaway is that successful SEM is not about generating connecting the right search with the right advertisement and the right landing page including right business outcome. So, if you have any doubts or
