What is SEO?
SEO stands for Search Engine Optimization – so search engine optimization. The aim is to design and structure a website in such a way that it appears as far as possible in the organic, i.e. unpaid, search results of Google and other search engines.
SEO covers various areas: the technical optimization of the website (load times, structure, indexability), the content orientation to relevant search terms, the establishment of a meaningful internal linking, as well as local signals such as Google company profile and location information.
The decisive difference to paid ads: SEO cannot be switched on and does not work according to a fixed schedule. Crawling, competition, initial position and quality of measures affect development. Organic clicks do not cause direct ad costs, build and maintain the website but remain an ongoing investment. The basics describe the official Google SEO Guide.
- Technical optimization: charging times, structure, meta data
- Content orientation to relevant search terms
- Building local signals (local SEO)
- Sustainable effect without continuous display costs
What is SEA?
SEA stands for Search Engine Advertising – paid advertising in search engines. The most famous system is Google Ads. Companies display ads that appear above or below the organic search results and are marked with the reference 'Published'.
The biggest advantage of SEA is direct taxability: campaigns can play out after release and existing budget ads. Range and actual delivery depend among other things on bid, ad quality, competition and settings. This makes SEA interesting for product matches, seasonal actions or clearly limited tests. Google explains the model in the documentation Google Ads and search ads.
The reverse is also clear: if a campaign is paused or the budget is limited, the paid range can also fall or end. The advertisements therefore do not replace understandable target page, clean success measurement or organic website basis.
- Immediate visibility after campaign launch
- High control of target groups, times and budgets
- Suitable for temporary campaigns and launches
- Visibility ends as soon as the budget is exhausted
