Online marketing glossary
Every profession has its own language – online marketing does too. So that you keep track in conversations and can assess offers correctly, here are the most important terms, explained briefly and clearly.

Search engines & AI: getting found
The biggest levers for online visibility. If you’re found in search engines like Google or in AI systems, you get inquiries without having to take action yourself.
- SEO – Search engine optimization
- Umbrella term for all measures that move a website up in the unpaid search results of Google and others: suitable texts, technical improvements and links from other websites.
- On-page SEO
- Everything optimized on your own website: content, headings, page titles, internal linking, load time and technical structure.
- Off-page SEO
- Everything outside your own website that signals trust: links from other sites (backlinks), business directories, mentions and reviews.
- GEO – Generative Engine Optimization
- The evolution of SEO for AI systems like ChatGPT, Perplexity or Gemini: all measures that lead to a business being named in AI answers. More about GEO
- AEO – Answer Engine Optimization
- Closely related to GEO: preparing content so that search engines and voice assistants can serve it directly as an answer – for example in question-and-answer form.
- AI Overview
- The AI-generated summary Google shows above the classic search results. It answers questions directly and names only a few sources. How AI chooses sources
- Local SEO – Local search engine optimization
- Targeted optimization for location-based searches like “bakery near me” or “roofer Trier.” Highly important for trades businesses and regional service providers. More about local SEO
- Keywords – Search terms
- The words potential customers are most likely to use when searching for your products or services. The quality of this research is decisive for the success of every further measure.
- Ranking – Position
- The position of your website in the search results for a specific search term. All SEO measures aim for the top spots, because they receive far more inquiries.
- Structured data – Schema.org
- Invisible additional information in a website’s code that tells search engines and AI systems clearly what they’re looking at: a business, an address, a review, an FAQ.
Paid advertising
Faster than SEO, but paid: visibility for a limited time in exchange for budget.
- SEA / Google Ads – Search engine advertising
- Paid ads that appear at the top of Google search results, usually labeled “Sponsored.” Unlike SEO, visibility is there immediately – but it ends as soon as the budget runs out.
- CPC – Cost per click
- The amount you pay per click on an ad – not per impression. A key cost factor in judging whether a campaign is worthwhile.
- Retargeting – Remarketing
- Ads that specifically reach people again who have already visited your website but haven’t inquired or bought. Often especially effective, because the interest is already there.
- Paid ads on platforms like Instagram or Facebook. They can be targeted very precisely by region, age or interests – ideal for reaching a limited target group precisely.
Website & user experience
Visibility only brings inquiries if visitors also take action on the website.
- Landing page
- A single page with one clear goal – such as making an inquiry – without distracting menus. Usually built specifically for an ad campaign or a topic.
- Conversion rate
- The share of visitors who take the desired action – call, fill out a form, buy. The most important metric for whether a website really works.
- Call to action – CTA
- The button or sentence that prompts the next step, e.g. “Get in touch now.” The principle: the simpler and clearer, the higher the conversion rate.
- A/B test
- Two versions of a page or ad are tested side by side in order to decide based on data rather than gut feeling which one works better.
- Load time – Core Web Vitals
- How fast your website loads and responds. Affects both your Google ranking and whether visitors stay or impatiently leave.
Content & social media
Content that builds trust – before an inquiry is even made.
- Content marketing
- Useful content – articles, videos, posts – instead of direct advertising. The goal: being seen as an expert and building trust over time that later turns into inquiries.
- Content calendar
- An editorial plan that sets which post appears on which channel and when. Ensures regularity – an important signal for customers and for the platforms’ algorithms.
- Building a presence on platforms like Instagram, Facebook or LinkedIn in a targeted, strategic way – with a clear goal and a clear target group instead of occasional posting.
- Engagement rate
- How many people interact with a post (likes, comments, shares) relative to its reach. Often says more about its effect than the mere number of followers.
- Influencer marketing
- Working with people who already have a community in order to use their trust for your offer. For local businesses often useful on a smaller scale, e.g. with regional multipliers.
Customer relationships
From first awareness to the inquiry – and beyond.
- Regular emails to prospects and existing customers. Keeps the relationship active and builds trust until interest turns into a concrete inquiry.
- Customer journey
- All the touchpoints a customer has with your business – from the first Google search to placing the order. Shows where prospects drop off or are convinced.
- Lead – Lead generation
- A concrete interest in getting in touch, e.g. a submitted inquiry or a callback request. Lead generation is the process of turning website visitors into such contacts.
- Review management
- A fixed process for asking satisfied customers for a review and responding to all reviews. Reviews via QR code
Measuring results & legal
So that “feels successful” can be backed up with numbers.
- KPI – Key performance indicator
- A concretely measurable figure by which success is judged – e.g. the number of inquiries per month instead of vague statements like “more visibility.”
- Traffic
- The number of visitors to a website in a given period. On its own, not yet proof of success – what matters is what those visitors do next.
- ROI / ROAS – Return on investment / on ad spend
- The ratio of money invested to the resulting profit or revenue. The key question for every measure: what comes back for every euro invested?
- GDPR & cookie consent
- Legal requirements for handling user data and tracking on your website – including the obligation to obtain consent with a genuine choice before analytics or advertising cookies are set.
