That leaves the blogging, SEO, email, and CRM tools sitting unused.

The time saved on setup was the one I felt immediately.
B12 Errores comunes que se deben evitar
Mistake #1: Publishing the First Draft Untouched
❌ Incorrecto: Generating a site and hitting Publish within five minutes.
✅ Derecha: Rewrite the homepage headline and service descriptions first. AI copy is a starting point, not finished text.
Mistake #2: Ignoring Page-Level SEO
❌ Incorrecto: Leaving every page with the same default title tag.
✅ Derecha: Give each page its own title and meta description before you announce the site.
Mistake #3: Treating the CRM as an Address Book
❌ Incorrecto: Collecting form submissions and never tagging or following up on them.
✅ Derecha: Tag every lead by source, then trigger an automatic follow-up email the same day.
Solución de problemas B12
Problem: Your Custom Domain Won’t Connect
Causa: DNS records point somewhere else, or they haven’t propagated yet.
Arreglar: Copy the exact records from Settings into your registrar. Then wait up to 48 hours before retrying.
Problem: The Generated Copy Sounds Generic
Causa: Your original business description was too short or too vague.
Arreglar: Use the AI prompt tool on each section. Name your customer and your city in the instruction.
Problem: Contact Form Submissions Never Arrive
Causa: Notification emails are landing in spam, or the form is missing a recipient.
Arreglar: Set a recipient address under form settings. Then submit a test and whitelist the sender.
📌 Nota: If none of these fix your issue, contact B12 support from the dashboard.
