| Criterion | Competitor | DeepSEOAnalysis |
|---|---|---|
| Core function | Keysearch (keysearch.co) is a budget-friendly keyword research and SEO monitoring tool designed for bloggers, niche site builders, content creators, and small business SEO. Core capability: keyword difficulty scoring and search volume data for Google — Keysearch's keyword difficulty (KD) score from 0–100 is calibrated for bloggers competing in mid-authority content niches, and many users find it more accurate for that segment than enterprise tools. Key features: (1) **Keyword research** — search volume, keyword difficulty, CPC, and related keyword suggestions for any seed keyword; (2) **SERP analysis** — the full first page of Google results for a keyword with authority metrics (DA, PA, backlinks) on each ranking page; (3) **Competitor keyword analysis** — enter a competitor domain and see which keywords it ranks for; (4) **Rank tracking** — daily keyword position tracking (Starter: 200 keywords; Pro: 500 keywords); (5) **Backlink checker** — basic backlink count and referring domain data (via integrated Majestic data); (6) **Content assistant** — basic content optimisation suggestions based on SERP analysis; (7) **YouTube research** — keyword data for YouTube search. Pricing: Starter ~$17/month (200 keywords tracked, 200 daily searches); Pro ~$34/month (500 keywords, 500 daily searches). No free tier for ongoing use (occasional free trials offered). | A crawl-based technical SEO and AI visibility auditor. Validates all structured data against Google's Rich Results specifications with property-level error detail, measures Core Web Vitals from real CrUX field data (not Lighthouse lab estimates), detects JavaScript rendering gaps, checks robots.txt and sitemap configuration, and scores GEO signals across five AI visibility criteria. Free with no signup. No keyword research, no rank tracking, no backlink data. |
| Keyword research and difficulty scoring | Keysearch's keyword difficulty score is the tool's central feature — calibrated specifically for the mid-authority site segment (DA 20–50) that many bloggers and niche site builders compete in. Users often cite Keysearch KD as more predictive for their niche than Ahrefs KD or Semrush KD at a fraction of the price. The keyword data includes: volume estimates (from Google Keyword Planner API), CPC (cost-per-click for PPC context), competition (paid ad competition, different from organic KD), and trend data. The SERP analysis view shows the first 10 results with DA, PA, backlink count, and keyword occurrence in title/URL — giving context to understand why the current top results rank and whether a new piece of content can compete. Keysearch also supports Keyword Planner-style broad match suggestions and questions filters for finding question-based queries. | No keyword research or difficulty scoring. DeepSEOAnalysis's connection to keyword research: after identifying target keywords with Keysearch and creating content targeting them, use DeepSEOAnalysis to audit the published page — checking that the structured data, canonical tags, Core Web Vitals, and AI visibility signals support ranking for those keywords. Keysearch identifies which keywords to target; DeepSEOAnalysis audits the technical readiness to rank for them. |
| Rank tracking | Keysearch includes daily keyword rank tracking on both Starter and Pro plans (200 and 500 tracked keywords respectively). The rank tracker shows daily position changes, historical position charts, and SERP feature detection (featured snippet, People Also Ask, image pack) for tracked keywords. Competitive rank tracking allows adding competitor domains to see their positions for the same keyword set — useful for understanding relative movement. The rank tracker is manual-entry: keywords must be added individually or via CSV import. | No rank tracking. DeepSEOAnalysis audits on-page technical signals that affect ranking potential — structured data validity, Core Web Vitals, canonical correctness, AI visibility — but does not monitor position over time. Natural workflow: Keysearch to track ranking position (outcome); DeepSEOAnalysis to audit technical health (diagnostic). When a tracked keyword loses rankings, use DeepSEOAnalysis to audit the page for technical regressions. |
| Technical SEO audit | Keysearch has minimal technical SEO audit capabilities. There is a basic on-page SEO checker that evaluates individual URLs for title tag, meta description, heading structure, keyword density, and page speed (using a third-party API). This is a surface-level check — it does not validate JSON-LD structured data, detect JavaScript rendering gaps, check canonical tag correctness, analyse robots.txt configuration, or measure real user Core Web Vitals from CrUX data. Technical SEO is not Keysearch's focus; it is a keyword research and rank tracking tool. | Full crawl-based technical audit: property-level structured data validation against Google's Rich Results specifications (identifying exactly which required property is missing and providing the corrected JSON-LD snippet), JavaScript rendering gap detection (schema present in rendered DOM but absent from server HTML), canonical tag correctness, robots.txt and sitemap analysis, real CrUX field data for Core Web Vitals (LCP, CLS, INP at p75 from actual user sessions), broken link detection, and AI visibility scoring across five GEO signals. Free with no signup, works on any publicly accessible URL. |
| Structured data and AI visibility | Keysearch does not validate structured data, detect JSON-LD errors, or score AI visibility signals. The on-page checker does not include structured data analysis. | Property-level structured data validation: checks every schema type present on the page (Article, Product, FAQPage, HowTo, LocalBusiness, BreadcrumbList) against Google's Rich Results specifications. Identifies missing required properties, incorrect value formats, and whether structured data is server-rendered or client-side only (GTM injection gap). Also scores five GEO/AI visibility signals: AI crawler access in robots.txt, llms.txt presence, FAQPage or HowTo JSON-LD, question-heading ratio (≥20% for GEO score), and content chunkability (avg section length ≤400 words). |
| Core Web Vitals | Keysearch does not measure Core Web Vitals. The basic page speed check references an external API but does not report CrUX field data or Lighthouse scores with any depth. | Real CrUX field data: LCP, CLS, and INP at the 75th percentile from real Chrome user sessions. This is the data Google uses in Page Experience ranking signals — more reliable than lab-environment Lighthouse scores for diagnosing actual ranking impact from performance issues. |
| Best fit | Keysearch is best for bloggers, niche site builders, and small business SEOs who need affordable keyword research and rank tracking — the KD score is well-calibrated for mid-authority sites, the SERP analysis view gives enough context to evaluate ranking difficulty, and the $17–$34/month pricing is significantly more accessible than Ahrefs or Semrush for individuals and small teams. It is a research and monitoring tool for understanding the keyword landscape and tracking rankings over time. | Best for technical validation after content is published: property-level structured data validation, real CrUX Core Web Vitals, JavaScript rendering gap detection, canonical analysis, and AI visibility scoring — free with no signup. Natural sequential workflow for bloggers and niche site builders: Keysearch to research and identify winning keywords → create content → DeepSEOAnalysis to audit the published page's technical health and confirm it is structurally ready to rank. |

FAQ
Keysearch (keysearch.co) is an affordable keyword research and rank tracking tool designed for bloggers, content creators, and niche site builders. Its main value proposition is a keyword difficulty (KD) score calibrated for mid-authority websites — many users find it more predictive for competitive analysis in typical content niches than enterprise tools like Ahrefs or Semrush KD. Keysearch also includes SERP analysis (showing the authority metrics of current top-ranking pages), competitor keyword research, basic backlink data, and daily rank tracking. Pricing: Starter ~$17/month (200 tracked keywords), Pro ~$34/month (500 tracked keywords). No free tier for ongoing use.
Keysearch KD is widely regarded as well-calibrated for the bloggers-and-niche-sites segment — DA 20–50 domains competing for informational keyword traffic. Users frequently report that Keysearch KD more accurately flags "easy to rank" opportunities for their authority level than Ahrefs or Semrush KD, which are calibrated against a higher-authority competitive baseline. The accuracy of any KD score depends on the algorithm used and the domain authority segment it's calibrated for — Keysearch's calibration suits independent content creators better than enterprise SEO teams competing for high-volume commercial terms. For any KD tool: always verify KD estimates by examining the actual SERP (who currently ranks, what their authority is, how well their content matches the intent) rather than relying on the number alone.
Keysearch is not a technical SEO tool. Its on-page checker does surface-level evaluation (title tag, meta description, keyword density) but does not validate structured data, detect JavaScript rendering gaps, audit robots.txt, or measure real CrUX Core Web Vitals. For keyword research, content planning, and rank tracking, Keysearch is cost-effective. For technical SEO audit, use a dedicated tool — DeepSEOAnalysis provides free property-level structured data validation, real CrUX field data for Core Web Vitals, robots.txt analysis, canonical tag validation, and AI visibility scoring for any URL, no signup required. The two tools address different jobs in the SEO workflow.
Keysearch does not have a permanent free tier — it occasionally offers free trials. The paid plans are Starter (~$17/month) and Pro (~$34/month), which are among the most affordable in the keyword research category. For comparison, DeepSEOAnalysis provides a complete technical SEO audit (structured data validation, real CrUX Core Web Vitals, robots.txt analysis, canonical tags, AI visibility scoring) for any URL with no signup and no payment required. The two tools serve complementary purposes: Keysearch for keyword discovery and rank tracking, DeepSEOAnalysis for technical audit and AI visibility — combined they cover the main SEO workflow for bloggers and niche site builders without requiring an enterprise-priced all-in-one suite.
