Lastmod vs Ahrefs

Ahrefs is built around its own web-wide data on links and keywords. Lastmod works from your own site and Search Console, with limited outside data around those queries: it ranks the changes to make and measures them.

Ahrefs

Its own index of the web

Lastmod

The evidence layer for your own site

Which fits

Choose Ahrefs if

  • You need backlink, keyword or competitor data about the wider web.
  • You track rankings for keywords beyond what Search Console shows you.

Choose Lastmod if

  • You want to know which change on your own site to make next, and what happened afterwards.
  • You want a result on thin traffic to say “not enough data” rather than show a figure.

Side by side

What Ahrefs does comes from its own website. Where that page doesn't name something, the table says “not mentioned”.

  • One ranked task list from your own data

What Lastmod does differently

  1. Your own data, in tasks

    Lastmod turns your site crawl and your Search Console data into ranked tasks, each with its reasoning, evidence and how sure it is.

  2. It follows the change through

    Lastmod looks for your new text on the page, then measures clicks before and after, says how reliable the measurement is, and says so when there is too little data.

  3. No web-wide index

    Lastmod has no backlink index, no keyword database and no rank tracking. It observes search results only for queries already in your Search Console, as dated snapshots, and does not research competitors beyond that.

  4. It never edits your site

    You make the change; Lastmod checks it and measures it.

Where Ahrefs is better

  • Data about any site

    Ahrefs describes tools to study competitors' websites, on its own web index. Lastmod sees your site, your Search Console and limited search-result observations for queries you already appear for.

  • Keyword research and rank tracking

    Keywords Explorer and Rank Tracker cover keyword research and tracking beyond what Search Console reports for your own pages.

  • Content and link research

    Content Explorer is described as a way to track web mentions and find link prospects. Lastmod has nothing like it.
