  • Titles and descriptions fit in a search resultPartial

    1 of the 2 audits in this goal falls short: The title is 598 pixels wide; search results show about 600 and may cut the end. Google sets no length limit and cuts a title or description to the device's width. SEO tools measure a title in pixels, since 60 characters run from 267 to 1,133 pixels, and count a description in characters. A cut loses the last words.

    • 598 pixels wide: https://www.publicstorage.com/

    What to do Ask the people who run your site to keep each title short enough to show in full and each description to one or two sentences, with the words that matter first.

    For your web team: Keep each <title> within about 560 pixels of Arial at 20px, which is about 60 characters of ordinary text and fewer with wide capitals, with the main words first. Keep each meta description to 70 to 155 characters.

  • Search engines and AI assistants are allowed to read your sitePass

    Every AI search crawler and agent we grade is allowed. Training crawlers are allowed. A crawler is a robot that reads sites for a search engine or assistant, and one that is blocked cannot recommend you. Bing lists blocking Bingbot among the things to avoid, because content it cannot crawl may not be indexed or used in Copilot's answers.

    Overview of OpenAI crawlers, OpenAI
  • Search engines may list each pagePass

    The page answers, no tag or header keeps it out of search results, and robots.txt lets search crawlers read it. Google leaves out a page marked noindex, and a page its crawler cannot read cannot be listed or used as a supporting link in its AI features.

    AI features and your website, Google
  • Search results can show your pages' wordsPass

    All 2 audits in this goal pass. A page whose text is kept out of results leaves a search engine or assistant nothing to quote. Google's AI features follow nosnippet and max-snippet, and Bing keeps content marked noarchive out of Copilot and limits nocache pages to their address, title and snippet.

    Robots.txt Introduction and Guide, Google
  • Your pages are listed in a sitemapPass

    https://www.publicstorage.com/sitemap_index.xml is a sitemap. Google and Bing use an XML sitemap named in robots.txt to find your pages, and neither promises to index every page in it. A page must be indexed to appear in Google's AI answers.

    Build and submit a sitemap, Google
  • Pages that do not exist say soPass

    A page that does not exist answers 404. Google treats content behind a 404 or 410 as gone, and flags empty pages that answer 200 (success) as soft 404s.

    How Google Search handles HTTP status codes, Google
  • Every page has its own titlePass

    The title is the page's own and describes it. Google builds the title link in search results from the page's title, and may change one that is missing, vague, boilerplate or repeated. A title of its own keeps your wording in front of searchers.

    Influencing Title Links in Google Search, Google
  • Key pages say what they offer in the titlePass

    The title says what the page offers. Google asks for descriptive titles. SearchPilot's test of putting the location at the start of a healthcare provider's titles predicted 8.5% more organic sessions.

    Adding Location to the Start of Title Tags, SearchPilot
  • Each page has a clear address and place in your sitePass

    All 2 audits in this goal pass. Google uses one canonical address per page, recommends readable words rather than long ID numbers, and can show a breadcrumb trail in desktop results when the page marks one up.

    How to Specify a Canonical with rel="canonical" and Other Methods, Google
  • Pages open without detoursPass

    Avoid multiple page redirects: the page has no redirect. Chrome says each extra redirect is another trip across the network that can delay the page by hundreds of milliseconds.

  • A shared link shows a previewPass

    The page names a title, description and image for shared links, and an icon. Open Graph tags decide the title, description and image a link shows when shared; Google shows your icon in results.

  • Your business is described in structured dataPartial

    The structured data lacks the business type and offer, and gives the business no keywords. The page does not state the business's address, latitude, longitude, opening hours, and price range. Structured data spares an assistant from guessing what a page means. Google says it gives explicit clues about a page; Bing says it may support clearer grounding and promises nothing.

    • The structured data names WebPage, Organization, ContactPoint, WebSite, SearchAction, and EntryPoint: https://www.publicstorage.com/
    • Not in the page's structured data: https://www.publicstorage.com/
    • No value on the business: https://www.publicstorage.com/

    What to do Ask whoever runs your site to mark the business up with the most specific schema.org type that fits it, to add the facts this goal lists to the structured data of the pages that show them, and to state on the page any detail this goal says the page does not state.

    For your web team: Add a JSON-LD script whose "@type" is the most specific schema.org type that fits the business, with each missing property set to the value the page shows, a node for each missing type on the page that shows it, and the value of each detail the page does not state in the text of the page. schema.org lists every type, its subtypes and the properties of each.

    About Usage Statistics, schema.org
  • Your key facts are in the page itselfPass

    Scripts add 44 pieces of text your server does not send, and none of it is what visitors come to the page for. Claude's web fetch tool does not support pages that fill in their text with JavaScript, and Google reads such a page only after its first HTML, once it reaches the rendering queue. A page whose first response is empty waits or looks empty.

    Understand JavaScript SEO basics, Google Search Central
  • A short guide to your site for AI assistantsPass

    llms.txt follows recommendations llmstxt.org proposes the file so assistants find what they need and follow its links. Lighthouse calls it an emerging convention and Google Search does not use it, so it is a bonus.

    Optimizing your website for generative AI features on Google Search, Google
  • Every page has its own summary for search resultsPass

    The description is the page's own and reads as a summary. Google can show a page's meta description as its snippet and asks for a different one on every page. It is less likely to show a list of keywords, so a specific summary has the best chance of being used.

    How to Write Meta Descriptions, Google
  • Headings give each page an outlinePass

    Heading elements appear in a sequentially-descending order Google's guide to AI features says headings give a page a clear structure.

  • Images describe themselvesPass

    All 2 audits in this goal pass. Alt text is a short written description of an image. Google calls it the most important attribute for adding metadata about an image, and it also uses computer vision on the picture. It asks for descriptive file names.

  • Pages say which language they are inPass

    All 2 audits in this goal pass. WCAG requires the language of each page to be set in its code, so software reads it with the right rules and voice.

    Rule html-has-lang: <html> element must have a lang attribute, Deque axe
  • Lists and tables are built as lists and tablesPass

    All 2 audits in this goal pass. WCAG, the web accessibility standard most laws point to, requires the structure a page shows on screen to be in its markup as well, and the axe rules check lists and tables for it.

  • Assistants can read your page's controlsMust haveFail

    Accessibility tree is not well-formed Chrome says agents review the accessibility tree to find what they can click or fill in, and missing labels can block them.

    A must have. While it fails, your letter stays at C or lower.

    • Elements must only use permitted ARIA attributes: <a class="promotion-modal" data-toggle="modal" data-target="#promotionModal" aria-label="info icon promotion tooltip">: https://www.publicstorage.com/

    What to do Ask whoever runs your site to run Google's PageSpeed Insights on the home page and fix the accessibility problems it lists, which are mostly buttons and fields with no label.

    For your web team: Give every button, link and field an accessible name, associate each field with a label, and remove invalid ARIA roles and attributes. PageSpeed lists the elements that fail.

    Accessibility for agents, Chrome
  • Your site offers tools to AI assistantsMust haveFail

    Your home page offers no tools to AI assistants. WebMCP lets an assistant book or reserve through a site's own code instead of guessing its way around the screen.

    A must have. While it fails, your letter stays at B or lower.

    • PageSpeed's "WebMCP tools registered" audit lists no tool: https://www.publicstorage.com/

    What to do Ask whoever runs your site to expose the main action on your site, such as booking or contacting you, as a WebMCP tool.

    For your web team: Call document.modelContext.registerTool({ name, description, inputSchema, execute }) as the home page loads, or add toolname and tooldescription attributes to the form. A name is 1 to 128 letters, digits, _, - or .

    WebMCP for developers, Chrome
  • Extra labels on controls are used correctlyPartial

    1 of the 10 audits in this goal falls short: Elements use prohibited ARIA attributes. Wrong ARIA tells an assistant a control is something it is not. WAI-ARIA defines the roles and attributes that are valid, and the axe rules check them.

    • Fix all of the following: aria-label attribute cannot be used on a a with no valid role attribute.: <a class="promotion-modal" data-toggle="modal" data-target="#promotionModal" aria-label="info icon promotion tooltip">: https://www.publicstorage.com/

    What to do Ask the people who run your site to remove ARIA markup that is invalid and to use plain HTML controls where they exist.

    For your web team: Use native elements first, give each ARIA role its required attributes and children, remove attributes the role does not allow, and keep ids unique.

    Rule aria-roles: ARIA roles used must conform to valid values, Deque axe
  • Text is readablePartial

    1 of the 3 audits in this goal falls short: [user-scalable="no"] is used in the <meta name="viewport"> element or the [maximum-scale] attribute is less than 5. WCAG requires text to contrast with its background by at least 4.5 to 1, and the axe rule color-contrast checks for it.

    • Fix any of the following: user-scalable on <meta> tag disables zooming on mobile devices: <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=0">: https://www.publicstorage.com/

    What to do Ask the people who run your site to darken pale text and to underline the links inside paragraphs.

    For your web team: Reach a contrast ratio of 4.5 to 1 for normal text, mark links in text with more than color, and leave user-scalable and maximum-scale out of the viewport tag.

    Rule color-contrast: Elements must meet minimum color contrast ratio thresholds, Deque axe
  • Forms are labelledPass

    Form elements have associated labels WCAG requires every form field to have a label or instructions, and the axe rule label checks for it.

    Rule label: Form elements must have labels, Deque axe
  • Custom controls announce what they arePass

    Elements with role="dialog" or role="alertdialog" have accessible names. WCAG, the web accessibility standard most laws point to, requires every control to expose its name and role to assistive technology and software.

    Accessibility for agents, Chrome
  • Buttons and links are big enough to tapPass

    All 2 audits in this goal pass. web.dev recommends tap targets of around 48 pixels, and WCAG sets a minimum of 24 by 24 pixels.

  • The main content shows up quicklyPartial

    2 of the 3 audits in this goal fall short: First Contentful Paint is 2.0 s for real visitors of this page, last 28 days, which Google rates needs improvement and Speed Index (8.3 s). Measured from real visitors of this page, last 28 days; the rest is a lab test on a phone. LCP is how long the main picture or text takes to appear, and visitors leave slow pages. web.dev says 2.5 seconds or less is good, one of Google's three Core Web Vitals.

    What to do Ask the people who run your site to make the first screen load faster on phones, starting with its biggest image.

    For your web team: Serve the largest element early: preload it, avoid render-blocking scripts and styles, and cut server response time. PageSpeed lists what holds it back.

  • Images are the right sizePartial

    2 of the 4 audits in this goal fall short: Improve image delivery (Est savings of 861 KiB) and Image elements do not have explicit width and height. Chrome says serving images larger than the version rendered on screen results in wasted bytes and slows page load.

    • Improve image delivery (Est savings of 861 KiB): <img alt="PS home main banner" src="https://images.publicstorage.com/Website/Promotions/2025/HalloweenSale/hal…" class="w-100">: https://images.publicstorage.com/Website/Promotions/2025/HalloweenSale/halloweenBanner2025_mobile.png

    What to do Ask the people who run your site to resize and compress your images before they go on the page.

    For your web team: Serve several sizes with srcset and sizes, use a modern format such as WebP or AVIF, and keep each image's width and height in the proportion it is shown.
