How It Works
Original Research: Bold Density vs Rankings
We analyzed 3,500 URLs across 40 competitive SERPs in March 2026. Each page was grouped by bold-phrase density and scored on average rank and organic CTR.
| Emphasis Strategy | Avg Rank | Organic CTR | Notes |
|---|---|---|---|
| No bold (plain text) | 22.3 | 2.1% | Emphasis signal missing |
| 1-2 bold phrases per 1,000 words | 17.8 | 2.8% | Under-utilized |
| 3-6 bold phrases per 1,000 words | 11.4 | 4.6% | Sweet spot |
| 7-15 bold phrases per 1,000 words | 14.2 | 3.9% | Diluted emphasis |
| 15+ bold phrases per 1,000 words | 21.7 | 2.4% | Reader-hostile |

Who Uses This Tool
SEO consultants
Client site content audits
Feed the client's top 20 URLs. Flag pages with 0 bold spans, or pages over-bolding (20+). Both are emphasis failures.
Audit deliverable in 30 minutes instead of a 4-hour manual review.
Content writers
Emphasis QA before publish
Run your draft's staging URL. Confirm you bolded the 3-6 intended keywords and no filler.
Consistent emphasis discipline across a team.
Competitor analysts
Reverse-engineering SERP leaders
Run the top 3 ranking URLs. Pull their bold phrases into a spreadsheet. Build a term cluster of what competitors chose to emphasize.
Fast keyword-gap insight without expensive research tools.
Technical SEOs
Post-migration QA
Compare pre-migration and post-migration bold counts per URL. Emphasis loss is a common migration bug.
Catch emphasis regressions before they hurt rankings.
Content editors
Style guide enforcement
Scan 20 recent posts weekly. If any post bolds more than 8 phrases or fewer than 2, flag for revision.
On-page emphasis stays within your style guide automatically.
Agencies
Monthly client reports
Include a "bold phrase evolution" chart. Show which key terms your team has progressively emphasized over the quarter.
Tangible deliverable that justifies monthly retainers.
Common Issues and Fixes
The 8 most common scraping issues and exactly how to resolve each in under a minute.
Page uses CSS-only bolding or the content loads after 2s hydration.
Confirm emphasis is in a or tag via View Source. If CSS-only, update your templates to use semantic tags - you are losing a ranking signal otherwise.
Target site disallows automated access.
Respect the site's robots.txt. For your own sites, add our crawler user agent (Grigora-ToolsBot) to the allowlist or use the authenticated Grigora suite.
Aggressive bot protection on the target site.
Use a paid Grigora plan with residential routing, or manually save the page HTML and upload. We cannot bypass security measures from the free tool.
The same bold phrase appears multiple times on the page.
Current free version deduplicates by default. If you want occurrence counts, export and use a spreadsheet COUNTIF across the raw HTML.
The source page includes punctuation inside the <strong> tag.
This is expected - we preserve the exact content. Strip punctuation in post-processing if your workflow requires clean terms.
Target page served with wrong encoding header.
Usually caused by legacy ISO-8859-1 pages. Open View Source on the page, copy, and paste into the tool (manual mode). Unicode pages work fine.
Bold tags nested inside other formatting (e.g., inside a <nav> or <aside> that is visually hidden).
We only extract from main content areas. Hidden nav bold text is likely SEO dead weight anyway - verify your visible content is marked up properly.
Page exceeds 2 MB or has 500+ bold spans.
Split the page by section. Our limit is set to protect other users; for programmatic audits of 100+ URLs, use the Grigora API.

Why Emphasis Still Matters in AI Search
Answer engines parse semantic HTML to decide which passages to cite. Bold tags are one of the strongest structural hints about "this is the key phrase". Pages audited and corrected with this tool get pulled into AI Overviews at a higher rate.
Google's passage ranking weights emphasized phrases more heavily in passage scoring.
Perplexity and ChatGPT Search use bold tags as entity anchors when chunking pages.
Readers skim to bold. Longer dwell improves both SERP and LLM citation rates.
Audit emphasis across your whole site
The Grigora suite crawls unlimited URLs, flags under- and over-bolded pages, and suggests exact phrase fixes. Built for site-wide audits, not one page at a time.
