loj.ac Backlink Analysis
Domain Score -, 146 referring domains, and top link sources from CrawlConsole.
Backlink Summary
Authority snapshot
This domain appears to have an emerging authority profile, where the strongest referring domains are worth inspecting first.
Backlink breadth
CrawlConsole found 146 referring domains and 146 backlink edges, which gives the profile enough breadth for segmentation.
Top sources to inspect
The strongest visible referring domains include vercel.app, tongji.edu.cn, shanghaitech.edu.cn. These are the first sources to inspect for relevance, anchor text, and repeatable link patterns.
Concentration pattern
The public sample is relatively distributed across visible referring domains, which is healthier than relying on one source.

Install CrawlConsole in your AI agent
Add the CrawlConsole MCP server once, then ask Claude Code or Codex to analyze loj.ac with live backlink data.
Install in Claude Code
- Run the installer for Claude Code from your terminal.Terminal
$ npx -y @crawlconsole/mcp -- --agent claude - Sign in when the browser opens and approve the agent key.
- Restart Claude Code so it loads the CrawlConsole MCP server.
Install in Codex CLI
- Add this configuration to your ~/.codex/config.toml file:~/.codex/config.toml
[mcp_servers.crawlconsole] command = "npx" args = ["-y", "@crawlconsole/mcp"] - Restart Codex to load the new configuration.
Methodology
CrawlConsole derives domain-level backlink and authority signals from Common Crawl link graph data. This public report shows a top referring-domain sample, Domain Score, harmonic centrality, and backlink breadth. Page-level source URLs, anchors, target URLs, and surrounding text require deeper evidence collection inside CrawlConsole.
