Why I tested Semdash and what surprised me
I started testing Semdash on 21 November and quickly moved to Plan 3 because I wanted to stress the platform. At first the landing page did not convince me, and I was vocal about the fact that most AppSumo “Ahrefs/Semrush killers” are trash. The main reason I normally dismiss new SEO tools is database size and accuracy. So when Semdash claimed 6.6 billion keywords and 2.7 trillion backlinks, I had to test it myself. That data claim made me take my word back and dig into the tool.
What does Semdash do well?
How good is the domain overview and strategy generator?
Semdash provides a familiar domain overview similar to what you expect from Ahrefs or Semrush: organic traffic estimates, backlink and referring domain counts, traffic distribution, position distribution and keyword trends. It also includes a “generate strategy” button that creates site-specific recommendations — not perfect, sometimes AI text appears garbled, but the suggestions are often useful and actionable. For example, it highlighted high-potential keywords ranked just outside the top positions and suggested content audits for pages that lost rankings.
Can Semdash find keyword gaps and backlink opportunities?
The keyword gap tool lets you compare your domain against competitors to surface missing topics and keyword volumes. You can filter by volume, competition and intent. The backlink gap report shows high-value pages and referring domains to target for outreach. These are the features I use most: they quickly reveal missing content areas and link opportunities. A caveat: I encountered errors when pasting full URLs incorrectly and some authority scores seemed off — so verify critical metrics against other sources.
How does traffic share analysis help my strategy?
Traffic share analysis is clever. Give Semdash a list of keywords you care about and it builds a competitor matrix based on average positions across those keywords, not just single-keyword wins. That helps identify competitors who dominate a niche across many terms, rather than one-hit-wonders. It also surfaces keyword counts so you can prioritise competitors who rank for a wider set of target phrases.
How useful is the competitor domain and traffic estimate reporting?
The competitor domain tool produces an AI-powered positioning map and an overall compare mode for all keywords a domain ranks for. Traffic estimates show period comparisons (1 year, 6 months, 1 month) and breakdowns — organic, featured snippet, local pack. Page-by-traffic highlights top-performing pages and their main keywords so you can reverse engineer what brings traffic.
Deep dive into keyword research
How many keywords can I research at once and how reliable are difficulty scores?
Semdash accepts up to 50 seed keywords in a single query and returned 2.5K related keywords in my test. You get filters for volume, CPC, paid competition, search competition, backlinks, domain rank and trend. The long tail discovery tool produces many low-competition long tail ideas. Important note from my tests: do not trust difficulty scores blindly — I saw seemingly unrealistic zero-competition flags for broad keywords. Always do a manual or cross-tool validation before committing to large content projects.
Backlink research and bulk analysis
Can I rely on Semdash for backlink intelligence?
Backlink reports are extensive: referring domains, anchor text ratios, top pages by links, live/broken/new/lost filters and bulk domain analysis. In one test the tool reported 2.2 million backlinks for a domain and exposed the anchor distribution and top referrers. The interface has occasional bugs, but the raw backlink opportunities are practical for outreach and broken-link building. Again, cross-verify authority metrics if you plan to invest resources chasing a link.
What bulk or batch features are included?
Bulk analysis allows you to upload multiple domains and produce a table of overall backlinks, domain counts, broken links and nofollow ratios. This is handy for competitive snapshots or agency-style audits where you need a quick comparison across many targets.
SERP, content explorer and AI features
Does Semdash include SERP history and content discovery?
Semdash includes a historical SERP checker that plots changes over time and related keywords for a given search term. The content explorer shows pages matching your topic but in my test much of the output looked like backlink attractor pages and the formatting felt spammy. The SERP history is interesting but I noticed some date quirks that might be a bug or a feature in how historical snapshots are shown.
Are the AI tools and Google AI overview useful?
There are AI overview and AI visibility modules that attempt to summarise Google AI citations and model what Google’s AI sees for a topic. The results were not well formatted and felt less useful to me than checking Google AI directly, but they might become valuable as Semdash improves formatting and sourcing.
Other notable tools in the platform
- People Also Ask and question trees for market research
- Keyword clustering and topic grouping
- Google Maps / local profile finder and lead generation (SMB) features
- Technology finder for identifying sites on WordPress or other stacks
- Search Console integration
What are the downsides I found?
- Interface bugs: occasional errors when pasting full URLs and flaky clicks.
- Formatting issues: some AI text and content explorer outputs feel messy.
- Metric accuracy: domain and page authority scores may need cross-checking with established tools.
- Credits: many features consume credits quickly, so monitor usage.
Final verdict: Is this Semdash Review recommending the tool?
In my view, Semdash is one of the better lifetime deals I have tested. It is not yet a 1:1 replacement for Ahrefs or Semrush on every front, but it provides a large database and a wide array of features that make it a highly useful tool if you are budget conscious. Use Semdash as a core part of your workflow for keyword discovery, gap analysis and backlink opportunity identification, but double-check difficulty and authority metrics with your trusted tools before making major decisions.
FAQs
Does Semdash really have 6.6 billion keywords and 2.7 trillion backlinks?
Semdash claims those database numbers and my tests show a very large index. The volumes make the tool worth testing, but you should validate specific metrics against established tools for critical decisions.
Can Semdash replace Ahrefs or Semrush for a small agency?
Semdash can cover most day-to-day needs: domain overviews, keyword gap, backlink gap, traffic estimates and keyword discovery. It may not match every single metric accuracy of top-tier tools yet, so use it alongside verification steps. For agencies on a budget, it is a strong contender.
How reliable are Semdash keyword difficulty and authority scores?
They are useful as directional indicators but not infallible. I recommend cross-verifying difficulty and domain/URL ratings with another SEO tool before major content or link investments.
Does Semdash consume credits quickly?
Yes. Several modules (backlink reveals, traffic estimates, lead generation) use credits. Monitor credit usage and pick the reports that matter most to your workflow.
