What makes a web agency SEO special

While traditional web agencies focus on design and aesthetics, a web agency integrates SEO from the very beginning. all important ranking factors.

Typical misunderstandings

• "SEO can be added later." Late SEO costs more: Those who integrate search engine optimization later often have to overcome technical hurdles.

After the launch, all core pages are immediately indexable - and achieve their first top 10 rankings within a few weeks, without any costly rework.
