[admin] Digital PR and link outreach for the tools and guides

[anurag629]

Context

Part of the SEO growth initiative (#18): Phase 3: Authority and off-page.
Links are what get competitive pages into the top 5. Free tools and useful guides are naturally linkable; we just have to pitch them.

What to do

• Pitch the tools and guides to dev newsletters, blogs, and relevant roundups.
• Search for unlinked brand mentions and ask for a link.
• Check competitor backlink gaps and pitch the same sites.

Where

External outreach.

Acceptance criteria

• Outreach list built and first round sent
• Any earned links recorded

Notes

Branch off develop (feat/*, docs/*, chore/*), open a PR into develop, and squash-merge. See CONTRIBUTING.md.
