Slow or hacked website: the 5 most common maintenance mistakes

A neglected website becomes slow, vulnerable and loses its search ranking. Here are the 5 most common maintenance mistakes and how to avoid them.

A website is never really "finished". Without regular maintenance, even the best-built site degrades over time. Here are the most common maintenance mistakes we see — and how to avoid them.

1. Never updating the CMS and plugins

WordPress sites in particular accumulate critical security updates. An outdated CMS or plugin is the number one entry point for hackers.

2. No automatic backups

In case of a hack, mistake or server failure, a recent backup is what separates a few hours of downtime from a total loss of years of content.

3. Letting unoptimised images pile up

Every photo added without compression makes the site heavier, slowing load times — an increasingly important Google ranking factor, especially on mobile.

4. Ignoring SSL certificate renewal

An expired SSL certificate shows an alarming security warning to visitors, instantly driving most of them away.

5. No uptime or performance monitoring

A site can go down for hours — or days — without anyone noticing if no monitoring tool is in place.

Conclusion

Website maintenance isn't an unnecessary expense — it's insurance against lost traffic, customers, and sometimes years of content. Web Mogador offers a monthly care package including hosting, backups, updates and monitoring.
