Current Scores

Web-graph authority (0-100)

Domain scores measure petersenindustries.com as a whole: every subdomain's links rolled up into one node of Common Crawl's domain-level web graph. Host scores measure the exact hostname petersenindustries.com. WWW scores cover the www variant of that hostname, which the graph tracks as its own entry since January 2026 (before that, www and bare host were merged). A big gap between domain and host usually means the domain's authority lives on other subdomains. PageRank is link-endorsement authority: how much weight the sites linking here carry themselves. Harmonic centrality measures reach: how close this site sits to the rest of the web when following links, which favors broadly connected sites over ones boosted by a few heavy linkers. All are normalized 0 to 100 within each crawl snapshot; a dash means that series does not exist for this site.

      "text": "Pipe plugs are versatile tools used to temporarily seal, block, or isolate parts of a pipeline. They are commonly used in plumbing, maintenance, and industrial applications to prevent the flow of liquids or gasses. Pipe plugs are essential for repairs, testing, and routine maintenance to ensure safe and efficient operation without affecting the entire system."

    "acceptedAnswer": {
      "@type": "Answer",
      "text": "Pipe plugs work by creating a secure seal within a pipe to stop or restrict the flow of liquids and gases. Depending on the type of plug, it can be inserted and mechanically expanded or inflated with air or water to fit snugly against the pipe walls. After use, the plugs are deflated, released, and removed from the pipe."

1. Pipe Size: Make sure the plug matches the diameter of your pipe.
2. Pressure Requirements: Select a plug rated for your system's pressure.
3. Material Compatibility: Ensure that the plug material is suitable for the fluids or gasses in the pipe.
4. Application Type: Determine whether you need a temporary or permanent solution.
5. Environmental Conditions: Check whether the plug can survive operating temperatures and chemical exposure.
Considering these factors will guide you in selecting the most suitable pipe plug for your specific requirements."

Web-Graph History

Authority over time

Every Common Crawl web-graph release since 2017, roughly quarterly. The domain series goes back to 2017; Common Crawl only began publishing the host-level graph in 2020, so host lines start there. Click a legend entry to show or hide that line. Flat lines are normal for established sites; watch for sustained rises or drops, which track real gains or losses in who links here.

A note on www: through the end of 2025 the source web graph merged www and non-www hostnames into the bare name, so one host line covers both. Starting in January 2026 the graph splits them into separate entries, which is why www can carry its own scores going forward.

Backlink Data

Backlink counts

Unique linking domains seen in Common Crawl's link graphs. This is a different dataset than the 0-100 authority scores above: these are raw counts, host-level for petersenindustries.com and domain-level for petersenindustries.com with all its subdomains combined. Common Crawl covers a large sample of the web, not all of it, so treat counts as comparable between sites rather than absolute totals.
