Link building agent for your SEO

most people are still manually prospecting for backlinks. it's 2026. you can automate 90% of this with an agent and a few APIs.

here's the exact stack:

1. find targets

pull your competitor's backlink profile from the ahrefs API or moz links API. export every referring domain. filter by DR 30+ and relevant niches. you can also hit the dataforseo backlinks API if you don't want an ahrefs subscription — pay per request, way cheaper at scale.

2. enrich contacts

run every domain through a waterfall enrichment sequence:

• hunter.io API → find emails by domain
• findymail API → catch what hunter misses
• prospeo API → third pass
• people data labs API → get the actual person behind the site

you're looking for the editor, content manager, or site owner. not info@ addresses.

3. score and prioritize

use the dataforseo domain metrics API to pull DR, traffic estimates, and topical relevance for each prospect. have the agent score and rank them. only outreach to sites worth your time.

4. scrape the actual page

use firecrawl API or jina reader API to pull the content of the page that links to your competitor. feed it to claude API with a prompt like:

"read this article. identify where a link to [your content] would add value. write a 3-sentence outreach angle based on what's missing."

this is what makes the emails not suck. the agent actually reads their content and finds a real angle.

5. generate the email

claude API writes the cold email. keep it short. one personalized line about their article, one line about your content, one CTA. no templates. every email is unique because it's generated from the actual page content.

6. send the sequence

push the emails into instantly API or smartlead API via their REST endpoints. 3-email sequence. follow up at day 3 and day 7. rotate across warmed sending domains.

cold email infra basics still apply:

• dedicated domains (buy 5-10 lookalikes)
• warm them for 2-3 weeks on instantly
• SPF/DKIM/DMARC on every domain
• keep volume under 30/day per account
• rotate sending accounts

7. track and log

instantly webhooks fire on replies. agent classifies responses (interested / not interested / negotiating) using claude API. positive replies get pushed to a google sheet or your CRM via API. agent can even draft the follow-up response.

the whole pipeline runs on a cron job. new competitor backlinks get scraped weekly, enriched, scored, and outreached automatically.

what used to take a VA 40 hours a week now runs for ~$50/month in API costs.
