The world of digital marketing is packed with acronyms and technical terms that can often feel overwhelming. Whether you’re a business owner looking to improve your online presence or just trying to keep up with marketing discussions, understanding these terms is essential.
To help, we’ve put together a glossary of key search engine marketing (SEM) terms, breaking down what they mean and how they’re used.
Essential Search Engine Marketing Terms
1. SEO (Search Engine Optimisation)
SEO is the practice of optimising a website to rank higher in search engine results. It involves improving content, technical performance, and links to increase organic (unpaid) traffic.
📌 Example: Using relevant keywords and creating high-quality content to help your website appear on page one of Google.
2. SEM (Search Engine Marketing)
SEM is a broader term that includes SEO and paid advertising (PPC). It focuses on increasing visibility in search engine results through a mix of organic ranking strategies and paid ads.
📌 Example: Running a Google Ads campaign while also optimising your website for organic search.
3. PPC (Pay-Per-Click)
PPC is an online advertising model where advertisers pay each time someone clicks on their ad. It’s commonly used in Google Ads and social media advertising.
📌 Example: A company bids on the keyword “best accountants in London” and only pays when someone clicks their ad in Google search results.
4. SERP (Search Engine Results Page)
SERPs are the pages displayed by search engines when users enter a search query. They include organic listings, paid ads, featured snippets, and other results.
📌 Example: If you search for “Italian restaurants near me,” the SERP will show a mix of local businesses, Google Ads, and map listings.
5. CTR (Click-Through Rate)
CTR is the percentage of users who click on a link after seeing it in search results, ads, or email campaigns. A higher CTR usually means your content or ad is engaging and relevant.
📌 Example: If 100 people see your ad and 10 click on it, your CTR is 10%.
6. Bounce Rate
Bounce rate refers to the percentage of visitors who leave your site without taking any action, such as clicking a link or filling out a form. A high bounce rate may indicate poor content, slow loading times, or irrelevant search traffic.
📌 Example: If users land on your website but leave within seconds, search engines may assume your site isn’t valuable for that search term.
7. Keyword Research
Keyword research involves finding the best words and phrases that users type into search engines. These keywords help businesses optimise their content to attract the right audience.
📌 Example: A florist looking to attract local customers might optimise their site with keywords like “flower delivery in Bath” or “best wedding bouquets.”
8. Backlinks
Backlinks are links from other websites to your site. They act as a “vote of confidence” for search engines, helping to improve rankings when they come from trusted sources.
📌 Example: If a well-known industry website links to your blog post, search engines will see your content as more authoritative.
9. Domain Authority (DA)
DA is a score (out of 100) that predicts how well a website will rank in search results. Sites with high DA scores are seen as more credible.
📌 Example: BBC, GOV.UK, and major newspapers have high DA scores due to their long history and strong reputation.
10. Organic vs Paid Traffic
Organic traffic comes from unpaid search engine results, driven by strong SEO efforts.
Paid traffic is generated through ads, such as Google Ads or Facebook Ads.
📌 Example: If your website ranks on page one of Google without advertising, that’s organic traffic. If you pay to appear at the top, that’s paid traffic.
