2 First Use

2.1. Activate the Blue Bar

1. Navigate to any web page (for example, wikipedia.org).
2. Wait 2-3 seconds. SEOwer's blue bar will automatically appear at the top of the page.
3. You will see the "SEOwer PRO" logo on the left and the main SEO metrics on the right.

2.2. Open the Control Panel

You have several ways to open the full panel:

• From the blue bar: click the "Open Panel" button (far right).
• From the extension icon: click the SEOwer icon in the browser bar and then "Open Full Panel".
• Keyboard shortcut (optional): you can configure a shortcut at chrome://extensions/shortcuts.

2.3. Select Language

The first time you open the panel, you will see a language selector. SEOwer automatically detects your browser's language, but you can change it at any time from the hamburger menu (?) ? Language.

3 The Blue Bar (SEObar)

The blue bar is the main SEOwer interface. It appears at the top (or bottom, according to your preference) of any website you visit. It has three contextual modes:

3.1. Normal Web Mode

It is shown on any standard web page. From left to right, it contains:

• SEOwer PRO Logo
• Main Keyword with its percentage density (automatically detected).
• Total words of the page.
• H1 / H2 / H3-H6 count for each heading level.
• Internal / External Links.
• Total images, with a note in parentheses if there are images without ALT.
• Scores: SEO, AI/GEO, Structure and Readability (each /100).
• "Open Panel" Button to open the full panel.
• Configuration (theme, position, snooze).
• Close the bar (you can restore it from the popup).

3.2. Google Mode (Home Page)

When you visit google.com without a search, the bar shows:

• SEOwer PRO Logo.
• An animated marquee with the message: "Transform data into decisions. Every SERP analyzed is a competitive edge gained..."
• Configuration and close buttons.

3.3. Google SERP Mode

When you are on the Google results page (google.com/search?q=...), the bar shows live analysis of the ranked results:

• Searched keyword (in quotes).
• Avg Meta Title: average characters of the ranked titles.
• Avg Meta Description: average characters of the descriptions.
• Avg Slug: average words in the slug (last URL segment).
• Levels: URL depth distribution (N0, N1, N2, N3+).
• Includes dates: how many results show dates in their content (signal of fresh content).

Additionally, on the Google page you will see two extra panels injected by SEOwer:

• Premium panel below each organic result with title, description, depth, SEO score (?????) and a "TECH & SPEED" button to audit that URL with one click.
• Right-side panel "SERP Analyzer" with 5 tabs (1 to 5-word n-grams) showing the most frequent terms in the ranked snippets. It is a powerful tool to identify which terms Google associates with your keyword.

4 Bar Configuration

Click the configuration icon (gear) on the blue bar to open the configuration panel. It has 3 sections:

4.1. Color Theme

Choose between Light (for light backgrounds) or Dark (the default theme, ideal for all websites). The change is applied instantly.

4.2. Bar Position

Select whether you prefer the bar At the Top or At the Bottom of the page. The bottom bar is useful to avoid covering the website's navigation menu.

4.3. Hide Bar (Snooze)

If you do not want to see the bar for a while, you can silence it:

• 24h: the bar is hidden for 24 hours.
• 1 week: it is hidden for 7 days.
• Always: the bar is hidden permanently (you can revert this from the popup).

4.4. Restore Bar

When the bar is hidden, a small tab (chevron) appears in the corresponding position. Click it to restore it immediately, or from the extension popup, click "Restore Hidden Bars" to clear all snooze state and reload the page.

5 The Control Panel (Dashboard)

The panel is the detailed view of the entire audit. It is divided into 10 specialized sections accessible from the left sidebar menu. The active section is persisted in storage, so when you open the panel again you'll find yourself where you left off.

5.1. Hamburger Menu (?)

In the top left, next to the SEOwer logo, you will see the three horizontal lines icon. Clicking it reveals 3 options:

• Instructions: link to this page.
• Send feedback: feedback form.
• Language: interface language selector.

5.2. CTA Card - Google Docs

At the bottom of the sidebar you will see a promotional card for the SEOwer add-on for Google Docs. Click "Install Add-on" to open the Google Workspace Marketplace.

6 Section 1: Diagnostic

It is the first section you will see when opening the panel. It offers a panoramic view of the SEO health of the page with an interactive radar, a visual semantic architecture map and the executive summary.

6.1. Semantic Authority Radar (4 weighted axes)

The core of the Diagnostic is a 4-axis radar with animated expanding wave. Each axis scores 0-100 with different weights:

• SEO On-Page (35%): meta tags, H1, keyword distribution, linking.
• Structure (30%): H1?H6 hierarchy, lists, tables, distribution.
• AI / GEO (20%): schema, AEO, Q&A, citability by LLMs.
• Readability (15%): Flesch, active voice, human markers.

The global score (0-100) is calculated with the weighted average and changes color according to the value:

• ? Green (80-100): Excellent. Well-optimized page.
• ? Orange (50-79): Acceptable. Clear areas for improvement.
• ? Red (0-49): Needs urgent work.

You can enter your manual target keyword in the radar field and press ? to recalculate all the page metrics with that exact keyword.

6.2. SERP Simulator

An exact visual representation of how your page would look in Google results. It shows the favicon, site name, full URL, title (in blue, like Google) and meta description. It helps you verify if your snippets are attractive and well-formatted before publishing.

6.3. Advanced Cards (Architecture Efficiency)

Three cards with advanced metrics:

• Architecture Efficiency (TGS): combines Graph Efficiency (40%) + RAG Coefficient (60%) to score the document's structural health.
• Semantic Footprint: top 10 entities and keywords with the highest actual density in the body.
• Schema Types: declared JSON-LD types (Article, Product, FAQ, HowTo...).

6.4. Global Summary of Technical Elements

A table with 4 rows summarizing the state of the 4 pillars:

• SEO On-Page: status of the Senior SEO score with label (Excellent / Acceptable with improvements / Action required).
• AI / GEO: suitability for AI Overviews, ChatGPT and Perplexity.
• Structure: H1?H6 hierarchical health and depth.
• Readability and NLP: text naturalness and AI patterns.

6.5. Semantic Architecture Map

A unique interactive visualization that shows the page as a hierarchical graph of blocks. Each block represents a section of the document, with its H1-H6 level, words, images and links. It is the fastest way to detect:

• Orphan sections without linking.
• Hierarchy jumps (H1 ? H3).
• Keyword concentration in specific blocks.

7 Section 2: SEO On-Page

This section performs a thorough technical audit sensitive to your target keyword with 18 weighted criteria. It is the operational view after the global Diagnostic summary.

7.1. Senior SEO Score (0-100)

Proportional system (sum 100) that weights each factor according to its real ranking weight:

• Title (15 pts): length 50-60 chars + keyword in the first 5 words.
• Meta Description (10 pts): length 140-160 chars + keyword in the first half.
• H1 (10 pts): a single H1 + keyword.
• Slug, first 100 words, density, length, image ALT, anchor texts, schema, canonical, hreflang and internal/external linking.

The score status is:

• Outstanding (=80): Outstanding audit.
• Acceptable (60-79): Acceptable with improvements.
• Critical (<60): Requires immediate action.

7.2. Strategic Keyword Positioning

10 cards that verify the presence of your target keyword in:

1. Meta Title — High Impact / Penalty if missing.
2. Meta Description — Improves CTR if present.
3. URL (Slug) — Ranking Factor.
4. H1 Title — High Impact / Penalty if missing.
5. H2+ Subheadings — Semantic Structure.
6. Keyword in Intro (first 100 words) — Above the Fold.
7. Keyword in Body (=3 occurrences) — Healthy Distribution.
8. Keyword in Conclusion (last 100 words) — Semantic Reinforcement.
9. Keyword in Image ALT — Image SEO.
10. Keyword in Image URL — Descriptive Filename.

7.3. Semantic Coverage and Co-occurrences (LSI)

Two columns with the most frequent bigrams and trigrams in your content. This helps you understand the real semantic field of your text and detect gaps your competitors cover.

7.4. Meta Tags and Social Signals (2026)

Three metrics for title and meta description length + completeness of Open Graph and Twitter Card. Plus checks for canonical tag, lang attribute and multi-language hreflang.

7.5. Content Quality and Depth

8 cards: editorial words, H1 uniqueness, Flesch, lexical richness, H2/H3 questions (PAA), freshness, bold text and detected Schema types.

7.6. Multimedia Health and Visual SEO

6 cards: ALT coverage, images with keyword in ALT, dimensions (anti-CLS), modern format (WebP/AVIF), lazy loading and total images.

7.7. Linking Architecture

4 cards: internal linking, external (citations), descriptive anchors and nofollow ratio on externals.

8 Section 3: AI & GEO

This section is dedicated to optimization for AI-based answer engines (ChatGPT, Perplexity, Gemini, Claude, Google AI Overviews). It is divided into three main blocks plus a detailed breakdown.

8.1. Trust and Authority (E-E-A-T)

Five checks of the Google E-E-A-T pillars (Experience, Expertise, Authoritativeness, Trustworthiness):

• Content freshness: publication date, modification date and age in days. Status: Recent (<1 year) / Outdated / No date.
• Knowledge Graph (sameAs): presence of links to LinkedIn, Wikipedia, Twitter or Crunchbase in Person/Organization schema. Reinforces E-E-A-T.
• Data Density: counts numbers, years and percentages. AIs reward content with empirical data.
• Citations or Sources: presence of blockquotes and references.
• Llms.txt: file /llms.txt that instructs LLMs on how to crawl and cite your website.

8.2. Answer Engine Optimization Format (AEO)

Four checks on the format extractable by featured snippets and AI Overviews:

• AEO Paragraph (60-80 words): detects paragraphs of optimal length for Featured Snippets.
• Lists and Tables: count of each (ideal structure for AI extraction).
• Multimodal SEO: presence of <figcaption> in <figure> and VideoObject schema for multimodal extraction.
• Q&A Format: questions detected in the content (conversational format for voice search).

8.3. Naturalness and Readability (Anti-AI)

Detector of typical AI patterns with two columns:

• Left - Readability: Composite score with Flesch adapted to the language (Fernández-Huerta, Amstad, Flesch-Vacca) and sentence/paragraph metrics.
• Right - Anti-AI Markers (7 metrics): excess of -ly adverbs, passive voice, lexical richness (TTR), sentence rhythm (CV), typical AI clichés, excessive connectors, over-explanation, robotic formatting, AI-style short titles, uniform structure, absence of first person.

8.4. Structured Data (Schema.org)

Lists the JSON-LD blocks detected with their types (Article, Product, FAQ, HowTo, BreadcrumbList...). If there is no schema, it warns you in red and suggests the most relevant types for your vertical.

8.5. Detailed GEO Breakdown

Expanded information on:

• Full JSON-LD code with syntax highlighting and validation of required properties.
• Semantic HTML5 architecture (article, main, nav, aside, header, footer) — AIs and search engines use these tags to extract the central content without being distracted by noise (menus, footers, sidebars).
• Conversational Q&A pairs extracted automatically.
• Full HTML of the detected tables.
• Structured lists with the first 5 elements.

9 Section 4: Structure (Headings)

A detailed view of the headings hierarchy H1-H6 of your content. Allows you to detect architectural problems before publishing.

9.1. Visual Summary H1-H6

A row with 6 boxes (H1 to H6) showing the exact count of each level. Useful for detecting problems such as:

• ? Multiple H1s (penalizes SEO).
• ? Total absence of H1 (the page has no semantic title).
• ? Level jumps (H1 ? H3 without H2 — breaks the logical hierarchy).
• ! Orphan headings (H2 without parent H1, detected by the RAG Coefficient).

9.2. Headings Tree

Tree view with dotted connector lines, progressive indentation by level, and colored badges per H1-H6 level. Each heading is shown with its real text and badges with the word count, characters, images (with ALT), videos, internal links, external links, tables and lists contained in that section.

9.3. TOC Indicator

If the page includes a visible Table of Contents, a green badge "INDEX DETECTED" appears, improving navigation and reducing bounce rate.

9.4. "Copy Headings" Button

Copies all headings to clipboard in H1 - Text format. Ideal for pasting them into another document or doing a quick audit. The button changes to "? Copied" for 2 seconds.

11 Section 5: Readability

This section evaluates the clarity and naturalness of the text with a Premium SaaS dashboard. It combines Flesch (word complexity), Flesch-Kincaid (sentence length), % passive voice, % adverbs ending in -ly, lexical richness (TTR) and AI pattern detector.

11.1. Main Indicators

• Reading time: calculated at 200 words per minute.
• Words per sentence: average of the document (optimal 12-18).
• Composite Readability score (donut): 0-100 with traffic light, color and level (General Audience / Technical-Complex).
• Dense paragraphs: warns if the average exceeds 45 words per paragraph (text wall).

11.2. Scannability (horizontal track)

Measures the visual impact of the content. Evaluates the presence of bold text, subheadings (H2/H3), lists and images that allow the user to scan the article quickly.

11.3. Lexical Diversity — Spheres by Repetition

Bubble chart that distributes the document's words into four categories:

• Unique (appear only once) — large green circle.
• Low Repetition (2-3 appearances) — medium teal circle.
• Medium Repetition (4-7 appearances) — small blue circle.
• High Repetition (more than 7 appearances) — small gray circle.

An article with many unique words and few high-repetition ones has good lexical richness; a text with a large high-repetition sphere is usually poor in synonyms and harms citability by LLMs.

11.4. Rhythm (sentence cadence)

Bar chart that measures the variability in your sentence length on a 0-10 scale. It is calculated with the Coefficient of Variation (CV = stdDev/mean) of your sentence length:

• 0-3: Monotonous (high probability of AI content).
• 4-6: Standard.
• 7-10: Dynamic and natural.

Below 0.25 CV the text is robotic; above 0.45 it is clearly human.

11.5. Anti-AI Detector

7 Patterns evaluated:

• -ly adverbs: excess indicates advertising / AI tone.
• Passive voice: percentage of total sentences.
• Lexical richness (TTR): unique words / total.
• Human markers: presence of first person, anecdotes, opinions.
• Excessive connectors: "however", "nevertheless", "therefore"…
• Over-explanation: redundant definitions of obvious terms.
• AI-style short titles: headings of a single generic word.

12 Section 6: Keyword Density

N-Grams analysis from 1 to 5 words with Local TF. It has 5 tabs (1, 2, 3, 4, 5 Words) and each shows a table with:

• Word combination (keyword or n-gram).
• Number of appearances.
• Density (% over total words).

12.1. Main Keyword Detection

SEOwer automatically detects your main keyword through a scoring system:

• 40 points: appears in the title.
• 30 points: appears in the slug.
• 20 points: appears in the meta description.
• +0.5 points for each additional appearance.

Automatically filters words with less than 4 characters and discards auxiliary verbs and problematic stop-words. This keyword is shown in the blue bar and used as target in the SEO On-Page panel.

12.2. Types and Entities

Additionally, density detects named entities (proper names, brands, products) and classifies them in the "Type" column to differentiate generic keywords from brand entities.

13 Section 7: Images

Complete audit of all real images in the content (excludes icons, UI logos and decorative pixels). Table with 5 columns:

• View: thumbnail (50x50) with SVG placeholder if loading fails.
• Name: file name extracted from the URL.
• ALT Attribute: alternative text (shows "No ALT" in red if missing).
• Dimensions: width x height in pixels.
• Estimated Weight: size in KB, calculated in real time via a HEAD request to the server.

13.1. Additional Statistics

SEOwer also analyzes internally (visible in the content script console):

• Images in modern format (WebP, AVIF, HEIC, JXL).
• Images with lazy loading (loading="lazy").
• Images without defined dimensions (CLS risk in Core Web Vitals).
• Large images (>200KB) that penalize performance.

14 Section 8: Links

Complete audit of all links in the main content (excludes menus and footers to avoid noise).

14.1. Counters and Chips

At the top you will see two colored badges and three informative chips:

• ? Internal: N (green)
• ? External: N (blue)
• Chips: Internal · External · Do/No-Follow.

14.2. Filter by Origin

A dropdown allows you to filter links by their location in the DOM:

• All
• Header
• Footer
• Menu (navigation menu)
• Body / Content (article body)

This helps you assess whether your strategic links are in the content body (where they weigh most for SEO) or only in menus and footers.

14.3. Links Table

Each link is classified with:

• URL complete.
• Type: Internal (green) or External (blue).
• Origin: Header, Footer, Menu or Body.
• Follow: Do Follow, No Follow, Sponsored, UGC or Unknown.
• Anchor: link anchor text.

15 Section 9: Competitive Comparison

Compare your page with up to N competitors in a table of 35+ metrics in real time, with the same audit engine you use for your website.

15.1. How to Use It

1. Copy your competitors' URLs (one per line) in the textarea.
2. Click "Generate SEO Comparison".
3. Wait a few seconds while SEOwer analyzes each URL (it may take a while depending on how many you enter and the CORS headers of each site).
4. A table will appear with your site (first column) and each competitor (additional columns). Boolean values are shown as green (Yes) or red (No) badges, and numerical ones are highlighted in green if they outperform you.

15.2. Compared Metrics (10 groups)

• Measure multilingual readability in draft.
• Apply GEO recommendations for LLMs before publishing.

17.2. How to Install the Add-on

1. Visit Google Workspace Marketplace.
2. Click "Install" and follow the steps.
3. Open Google Docs, go to Extensions ? SEOwer.
4. Start writing and you will see the analysis in the side panel.

17.3. Compatibility with the Extension

The scoring system of the add-on and the extension are aligned, so the recommendations you see in Google Docs correspond to the metrics you will see later when analyzing the published URL with the Chrome extension.

18 Cambio de Language

SEOwer is available in 6 languages: Spanish, English, German, French, Italian and Portuguese.

18.1. From the Panel

2. Select Language.
3. Choose your preferred language.
4. The panel updates instantly.

18.2. Automatic Detection

The first time you install SEOwer, it will detect your browser language. If you want to change it later, you can do so at any time.

18.3. Blue Bar Language Change

The blue bar is also translated automatically when you change the language from the panel. If you navigate to a new page, the bar will be recreated in the selected language.

18.4. Language Privacy

Your language preference is saved locally in your browser (chrome.storage.local). It is not sent to any server.

19 Frequently Asked Questions (FAQ)

? Is SEOwer free?

Yes, 100% free. There is no premium version, no micropayments, no upsells. The goal is to democratize access to professional SEO tools.

? Does it send my data to any server?

No. All auditing is performed in your browser. Information is only sent if you voluntarily use the "Send feedback" form.

? Why does the weight of some images appear as "Blocked for security"?

Some servers block CORS (Cross-Origin Resource Sharing) requests. This is not an SEOwer error, but a server configuration of the image. In these cases, use PageSpeed Insights to get the real weight.

? Does it work on pages with login (Gmail, online banking, etc.)?

For security, SEOwer does not activate on certain restricted pages. The blue bar will not appear on them, but the control panel will remain accessible.

? Does it consume a lot of resources?

No. SEOwer uses chrome.storage.local and maintains a 5-minute cache per URL. RAM consumption is minimal.

? Why don't I see the blue bar on some websites?

It may be because:

• The website has a very restrictive CSP policy that blocks extensions.
• You have silenced the bar (check the popup and click "Restore Hidden Bars").
• It is an internal domain (chrome://, about:, file://...)..

? How can I suggest an improvement?

Use the "Send feedback" form in the hamburger menu of the panel. I personally read every feedback.

Do you plan to add more languages?

Yes, if there is demand. The next languages will be: Chinese, Arabic and Japanese.

? Can I use SEOwer to audit competitors' websites?

Of course. All the information that SEOwer analyzes is public and accessible simply by visiting the URL. Use it ethically to understand the sector and improve your own content.

? Does the Google Docs add-on have a cost?

No, it is also free. The add-on and the extension are complementary: use the extension to analyze published websites and the add-on to optimize drafts before publishing.

? How do I contact the developer?

By email at hola@agenciaseonetbulb.com or via LinkedIn (@jorgesanmos). I usually respond within 24-48h.
