Keyword Research
When comparing the platforms for keyword research, evaluate how each surfaces discovery, intent, difficulty, and volume. SEO metrics are estimates and can differ between software platforms — treat them as directional signals rather than exact figures.
| Area | Semrush | Ahrefs |
|---|---|---|
| Keyword discovery | Broad keyword discovery with related and phrase-match suggestions | Broad keyword discovery with related and suggestion features |
| Search intent | Intent indicators included with keyword data | Intent indicators included with keyword data |
| Keyword difficulty metrics | Proprietary difficulty estimate; metrics are estimates | Proprietary difficulty estimate; metrics are estimates |
| Search-volume estimates | Estimated search volume; can differ between platforms | Estimated search volume; can differ between platforms |
| Related keywords | Related and question-based keyword ideas | Related and question-based keyword ideas |
| Competitor keywords | Research keywords competitors rank for | Research keywords competitors rank for |
Competitor Research
Competitor research can answer practical questions about which keywords and pages competing sites rank for. Treat third-party traffic and visibility estimates as approximate figures rather than exact numbers.
| Area | Semrush | Ahrefs |
|---|---|---|
| Competitor keywords | Identify keywords a competitor ranks for | Identify keywords a competitor ranks for |
| Top pages | See pages estimated to attract organic traffic | See pages estimated to attract organic traffic |
| Backlink profiles | Review competitor backlinks and referring domains | Review competitor backlinks and referring domains |
| Content opportunities | Identify content gaps between competing sites | Identify content gaps between competing sites |
| Search visibility | Estimated visibility metrics; estimates only | Estimated visibility metrics; estimates only |
Backlink Analysis
Both platforms research backlinks and referring domains. Backlink databases and authority metrics are proprietary estimates and can differ between providers, so compare figures directionally rather than as absolute counts.
| Area | Semrush | Ahrefs |
|---|---|---|
| Backlink research | View backlinks pointing to a domain or page | View backlinks pointing to a domain or page |
| Referring domains | See referring domains and their authority estimates | See referring domains and their authority estimates |
| Link discovery | Discover new and lost links over time | Discover new and lost links over time |
| Competitor backlinks | Analyze competitor backlink profiles | Analyze competitor backlink profiles |
| Link-building research | Identify outreach and link opportunities | Identify outreach and link opportunities |
Site Auditing
SEO auditing software can help identify technical and on-page issues. Fixing flagged issues can support better crawlability and indexing, but neither platform guarantees higher Google rankings.
| Area | Semrush | Ahrefs |
|---|---|---|
| Crawlability | Crawl checks for indexability and access issues | Crawl checks for indexability and access issues |
| Internal linking | Identify internal linking opportunities and issues | Identify internal linking opportunities and issues |
| Metadata | Review title, meta, and heading issues | Review title, meta, and heading issues |
| Broken links | Surface broken links and redirect issues | Surface broken links and redirect issues |
| Indexing signals | Highlight indexing-related issues | Highlight indexing-related issues |
| Page-level issues | Page-level SEO issues summarized in a report | Page-level SEO issues summarized in a report |
| Technical SEO | Technical SEO checks across the site | Technical SEO checks across the site |
Rank Tracking
Rank tracking monitors selected keywords over time. Search rankings fluctuate for many reasons, and no software can guarantee rankings — use tracking to observe trends, not to promise outcomes.
| Area | Semrush | Ahrefs |
|---|---|---|
| Keyword positions | Track selected keyword positions over time | Track selected keyword positions over time |
| Location/device | Location and device options for tracked keywords | Location and device options for tracked keywords |
| Competitor visibility | Compare competitor visibility for tracked keywords | Compare competitor visibility for tracked keywords |
| Historical movement | Review historical ranking changes over time | Review historical ranking changes over time |
Content Research
These tools can assist with topic discovery, competitor content analysis, and content-gap research. Software-generated recommendations do not guarantee traffic — they inform decisions that still require judgment and execution.
| Area | Semrush | Ahrefs |
|---|---|---|
| Topic discovery | Research topics based on search and competitor data | Research topics based on search and competitor data |
| Keyword research | Use keyword data to inform content plans | Use keyword data to inform content plans |
| Competitor content | Analyze competing content and its performance | Analyze competing content and its performance |
| Content gaps | Identify content gaps between sites | Identify content gaps between sites |
| Existing-page optimization | Research ways to improve existing pages | Research ways to improve existing pages |
