Search Engine Marketing

Paid Search vs Organic Search in SEM

Search engine marketing splits into two main areas: paid search and organic search. Paid search means buying ad space on search engine results pages. Organic search means earning unpaid rankings through optimisation.

Many marketers use SEM to mean only paid search. Others use it as an umbrella term for both paid and organic. Google itself separates the two: it calls paid search 'Google Ads' and organic search 'SEO'.

The difference matters for budgets and teams. Paid search gives fast visibility. Organic search takes longer but can bring traffic without ongoing ad spend. A what website ranking means strategy often combines both.

For example, a company launching a new product might run paid ads to get immediate traffic while also investing in SEO to build long-term organic presence. This dual approach balances short-term gains with sustainable growth.

Another example: a local restaurant might use paid search to promote a weekend special, while also optimising its menu pages for organic queries like 'best pizza near me'. The paid campaign drives immediate bookings, and the organic effort builds ongoing visibility.

How Paid Search Campaigns Work

Paid search campaigns let you bid on keywords. When someone searches for that keyword, your ad may appear. You pay only when someone clicks your ad. This is called pay-per-click (PPC) advertising.

You manage campaigns through platforms like Google Ads and Microsoft Advertising. You choose keywords, write ad copy, set bids, and target audiences. You also track conversions to measure success.

Common metrics include click-through rate (CTR), cost per click (CPC), conversion rate, and return on ad spend (ROAS). These tell you whether your campaign is profitable.

For example, a local bakery might bid on 'fresh bread near me' and set a budget of £10 per day. When someone searches that phrase, Google runs an auction. The bakery's ad appears if its bid and quality score beat competitors. The bakery pays only if someone clicks. Over a week, it might get 50 clicks, 5 of which lead to an online order. The ROAS is calculated by dividing the revenue from those orders by the ad spend. This example shows how each campaign element works together.

Another example: an online shoe store bidding on 'running shoes' might target people in the UK, set a maximum bid of £0.50, and write an ad that says 'Free delivery on all running shoes'. It can also use ad extensions like site links to show specific categories. The store can test different headlines and descriptions to see which get more clicks. This testing is called A/B testing and is a standard part of paid search management.

• Keyword research: find terms your audience searches for.
• Ad copywriting: write headlines and descriptions that attract clicks.
• Bidding: set how much you are willing to pay per click.

The Role of SEO in Search Engine Marketing

Organic search engine marketing is another name for SEO. It focuses on improving unpaid rankings in search results. This involves optimising your website's content, structure, and technical setup.

SEO does not cost per click. But it requires time and effort. Results can take weeks or months. Once you rank well, you can get steady traffic without paying for each visit.

Enterprise SEO and enterprise search engine marketing refer to large-scale programmes. These involve many pages, larger teams, more approvals, and complex reporting. They are common in big organisations.

For instance, a news website might optimise its articles for keywords like 'UK election 2024' by writing detailed guides, using proper headings, and making sure the page loads fast. It might also build backlinks from other reputable sites. Over months, that page could rank on the first page of Google for that query, bringing thousands of visits each day without any ad spend.

Another example: a small business selling handmade soap might optimise its product pages for 'organic lavender soap'. It would include the keyword in the title, description, and image alt text. It would also ensure the site is mobile-friendly and has a clear navigation structure. This kind of on-page and technical SEO helps the page rank higher over time, attracting visitors who are ready to buy.

Common SEM Platforms and Tools

The main platform for paid search is Google Ads. It runs ads on Google Search and partner sites. Microsoft Advertising runs ads on Bing and Yahoo. Both offer similar features.

Google search engine marketing is just SEM carried out on Google Search. It uses Google Ads and related placements like Shopping ads. Many businesses start with Google because it has the largest audience.

Industry directories and agency listings often use SEM to mean paid search agency services. These include managing shopping ads, landing pages, and conversion tracking. A search engine submission is a separate, older practice that does not guarantee ranking.

Key Metrics and Performance Measurement

You measure SEM success with several metrics. Click-through rate shows how often people click your ad. Conversion rate shows how many clicks lead to a desired action, like a purchase or sign-up.

Return on ad spend (ROAS) compares revenue to ad cost. Return on investment (ROI) includes all costs, not just ad spend. These metrics help you decide whether a campaign is worth continuing.

A search engine position report can show where your ads or organic listings appear. But position alone does not tell you about profitability. Always look at conversions and revenue.

For example, a campaign might have a high CTR of 10% but a low conversion rate of 1%. That means many people click but few buy. The ROAS might be below 1, meaning you spend more than you earn. In that case, you might adjust the ad copy or landing page to improve conversions.

Another example: an e-commerce store running a campaign for 'winter coats' might see a ROAS of 4, meaning every £1 spent brings £4 in revenue. That is profitable. But if the ROI is lower because of additional costs like agency fees, the campaign might still be worth optimising further.

• Click-through rate (CTR): percentage of people who click your ad after seeing it.
• Conversion rate: percentage of clicks that result in a desired action.
• Return on ad spend (ROAS): revenue divided by ad cost.

SEM for Different Business Types

SEM works for many kinds of businesses. A search engine marketing company in Plano might help local businesses run ads. A multifamily search engine marketing campaign could target people searching for apartments.

Search engine marketing apartments is a specific use case. Property managers bid on keywords like 'apartments for rent' to attract tenants. They often use location targeting to reach local searchers.

Even niche queries like 'weed search engine marketing' exist. Cannabis businesses use SEM where legal, but face restrictions on many platforms. Always check platform policies before starting.

For example, a dentist in Manchester might run a Google Ads campaign for 'emergency dentist Manchester'. They set a radius target of 10 miles and use ad scheduling to show ads during office hours. This ensures the budget is spent on relevant, local searches.

Another example: an online course provider might target keywords like 'learn Python online' and use remarketing to show ads to people who visited the site but did not enrol. This helps capture high-intent users who need a nudge to convert.

How SEM Differs From Other Search Practices

SEM is not the same as search engine placement, which is an older term for getting a site listed. It is also different from submit website to search engines, which does not improve ranking.

search engine visibility is a broader concept. It includes both paid and organic presence. SEM is one way to achieve visibility, but not the only one.

An internal search engine is a search tool on your own website. It is not part of SEM. SEM focuses on external search engines like Google and Bing.

To understand where SEM fits, you need to know what what search engines means – they are the platforms that index web pages and return results for queries. SEM uses these platforms to reach users, whereas other practices like submitting a URL to a directory do not actively attract traffic.
