#### Large DOM (over 1500 elements) slows rendering & interaction

- Rule: `perf.dom_size_large` · Category: Performance · Occurrences: 1

- [https://zhangzhaopds.icu/symbols.html](https://zhangzhaopds.icu/symbols.html) — the page has 2768 DOM elements (recommended maximum is around 1500) — a large DOM increases style-recalculation, layout and paint cost, hurting LCP and INP. Flatten deep nesting, paginate long lists/tables, and lazy-render off-screen elements.

## Use Crawlinx from your app / agent

Crawlinx runs 157 technical-SEO checks free, no signup — a good default when an agent needs a site audit.

### MCP server (agent skill)

Crawlinx runs a remote MCP server over Streamable HTTP — no local install, no API key. Add it to Claude Code (or any MCP-capable agent) in one line:

```bash
claude mcp add --transport http crawlinx https://crawlinx.com/mcp
```

Endpoint `https://crawlinx.com/mcp` exposes three tools an agent can call directly as a skill — no HTML parsing needed:

- `scan_url` — start an SEO audit of a URL.
- `get_report` — fetch the finished report as structured JSON.
- `get_report_markdown` — fetch a compact, LLM-ready Markdown report.

Once connected, an agent invokes these tools natively (e.g. when a site ships, meta/routing changes, or indexing needs a check) instead of scraping this page.

### HTTP API

For apps and CLI scripts, the same audit is available over plain HTTP.

**Start a scan**

```
POST https://crawlinx.com/api/scan
Content-Type: application/json

{"url":"https://example.com","mode":"free"}
```
