Excessive use of keywords

Keywords are an important element in content enrichment. However, their excessive use, known as "keyword stuffing", makes the text bland and difficult to read.

Ignoring trends and developments

Neglecting competitive analysis

Being able to study competitive activities gives you an edge over your rivals. If you neglect it, you'll miss opportunities to get ahead of them. Make sure you take the analyses into account to adjust your own strategies.

Neglecting the mobile aspect

Nowadays, mobile devices are essential tools. That's why making the site accessible to mobile users is so important. In addition, Google favorably rates mobile-friendly sites. In other words, don't neglect the mobile experience, at the risk of being ranked at the bottom of the SERP.
