<p>(if you are not familiar with Zipf’s law, you may wish to look at the screenshots first, as they provide a visual context for the following)</p>
<p>Zipfstats is built around Zipf’s law, which states that given some corpus (in this case, a post/page) of natural language, the frequency of any word is inversely proportional to its rank in the frequency table. In a perfect Zipfian distribution, this would mean that the most frequent word in the corpus will occur twice as often as the second most frequent word, three times as often as the third most frequent word and so on. Any given real world corpus, if large enough, will tend to approximate a Zipfian distribution (this also works for cities as ranked by population, though that observation is less useful in this context).</p>
<p>The Zipfstats widget analyzes and reports word frequency by rank of a given single post or page (aka the corpus). The widget shows a small graph that plots the actual frequency-rank distribution of the content against a perfect Zipfian distribution, thus illustrating the degree to which the content follows Zipf’s law. It also provides for a table of the top-ranked words.</p>
<p>Zipfstats only analyzes the core content of a given post/page. It does not incorporate comments into its calculations. By default, it removes shortcode-generated content from its analysis, though you may optionally enable it. Filters, other than do_shortcode() (in the aforementioned case), are not affected in terms of the analysis. Actual output of the original content is unchanged, regardless of the options selected.</p>
<p>Options</p>
<ul>
<li>Show Only to Admin Users (default = on): only admin-level users see Zipfstats output. If unchecked, all users, logged or non-logged, will see it.</li>
<li>Strip Shortcode Content from Analysis (default = on): skips processing of and removes all shortcodes from the content of the post or page prior to analysis. Actual content remains unaffected.</li>
<li>Include Graph (default = on): Display a log-log plot of word frequency data against a perfect Zipf distribution</li>
<li>Include Word Frequencies (default = on): in addition to the Zipf plot, this option includes a table of the top n words in rank order as well as the frequency of their occurrences in raw terms. A clickable header allows the user to toggle between showing/hiding the wordlist.</li>
<li>Expand Word Frequency Table by Default (default = on): if expand is selected, the wordlist (if also selected) will be displayed on initial page load. Unchecked, the user will have to toggle its display manually via a clickable header.  </li>
<li>Number of Words to Show (default = 10, max 25): this determines the number of words to appear in the “top n” wordlist table, if the latter is enabled. This option does not affect any calculations.</li>
</ul>
<p>Some things to note:</p>
<ul>
<li>No site data is modified or stored. Widget results are generated on the fly. Zipfstats does not directly initiate any database activity, but merely uses the the $post object to analyze content, and the WordPress widgets API to store a handful of options.</li>
<li>Post/page content will be displayed as normal. If the widget is added to a sidebar, it will appear where placed, again, without any change to existing post/page content.</li>
</ul>
<h4>Future Enhancements</h4>
<ul>
<li>Add site-wide/category-wide/author-wide analyses</li>
<li>Add to admin post/page edit</li>
<li>Add recommendations to better approximate a Zipfian distribution</li>
</ul>

<h3>WooCommerce Optimization</h3>
<p>CranSEO includes a dedicated optimization engine for WooCommerce products, helping store owners create product pages that are not only search-friendly but also highly visible to LLMs and AI-driven search engines.</p>
<p><strong>How It Works: Step-by-Step</strong><br />
<em>Click “Analyze Product”</em><br />
With one click, CranSEO scans the product’s title, description, and short product description for SEO and LLM optimization factors.</p>
<p><em>Get Real-Time Scoring & Suggestions</em><br />
The plugin then displays:<br />
1. A comprehensive SEO score for the product<br />
2. Suggestions to improve keyword placement<br />
3. Warnings for missing or weak elements<br />
4. Tips to make the content more conversational and structured</p>
<p><strong>Optimization Targets</strong><br />
<em>Short Product Description</em><br />
Ensures this snippet is compelling and keyword-rich — ideal for appearing in quick previews or featured listings.</p>
<p><em>Long Description</em><br />
Analyzes for content depth, structure, and relevance to LLM queries (e.g., FAQs, benefits, comparisons).</p>
<p><strong>Built-in Product SEO Scoring</strong><br />
Each WooCommerce product is scored based on:<br />
1. Keyword relevance and density<br />
2. Conversational tone and clarity<br />
3. Content structure (headings, bullets, etc.)<br />
4. Link usage and metadata completeness<br />
5. LLM compatibility (Is the content likely to be cited or used by AI?)</p>
<p><strong>Why it matters</strong><br />
Most WooCommerce SEO plugins focus on meta tags — CranSEO goes further by optimizing the actual product content for visibility in LLM-powered platforms like ChatGPT, Google’s AI Overviews, and voice search.</p>
<h3>XML Sitemaps</h3>
<p>CranSEO automatically generates a complete and compliant XML sitemap to help search engines easily discover and index all your important content — including pages, posts, products, categories, and custom taxonomies.</p>
<p><strong>What It Includes</strong><br />
The sitemap dynamically includes:<br />
1. Pages – All published static pages<br />
2. Posts – Blog articles and other post types<br />
3. WooCommerce Products – Product pages with SEO relevance<br />
4. Categories & Tags – Blog and product categories/tags<br />
5. Custom Taxonomies – Including WooCommerce product attributes or any CPT taxonomy</p>
<p><strong>Search Engine Ready</strong><br />
Once generated, users can submit the sitemap directly to major search engines (like Google and Bing) via:<br />
1. Google Search Console<br />
2. Bing Webmaster Tools<br />
3. Manual submission or plugin integrations</p>
<p>The sitemap is located at:<br />
yourdomain.com/sitemap.xml</p>
<p><strong>Automatic Updates</strong><br />
CranSEO ensures your sitemap:<br />
1. Updates automatically when new content is published<br />
2. Removes deleted content from the index<br />
3. It has timestamps to show when you update the content</p>
<p><strong>Why Sitempas Matter</strong><br />
<em>Search engines rely on sitemaps to:</em><br />
1. Discover your content faster<br />
2. Understand your site structure<br />
3. Prioritize what to crawl and index<br />
4. And in the AI era, structured sitemaps help LLMs and bots find and contextualize your content better — especially when paired with CranSEO’s content optimization.</p>
