Speed

9 to fix87
  • 8 third-party services on the page

    8 third-party services load with your homepage (Google Tag Manager, Facebook and Clarity and others), adding 2.6 MB and 923 ms of main-thread time.

  • Mobile performance score: 87

    87/100

    Your mobile performance score is 87 (desktop: 87). Pages that score under 90 lose visitors before the first paint.

  • Render-blocking requests

    750 ms

    3 files block the first paint until they finish downloading. Deferring or inlining them could save about 750 ms.

  • Improve image delivery

    589 KiB

    3 images could be 589 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

  • Reduce unused JavaScript

    570 KiB

    About 570 KiB of JavaScript is downloaded but never used on this page.

  • Google Tag Manager adds 412 ms

    412 ms

    Google Tag Manager costs a phone 412 ms of main-thread work and 662 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

  • Use efficient cache lifetimes

    399 KiB

    19 files are served with short cache lifetimes, so returning visitors download them again (399 KiB).

  • Main-thread work: 3.2 s

    A phone's processor spends 3.2 s on main-thread work while loading, 1.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

  • website-files.com adds 122 ms

    122 ms

    website-files.com costs a phone 122 ms of main-thread work and 1.5 MB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

  • 7 long tasks on the main thread

    7 long tasks block the main thread while loading, the longest for 167 ms. During a long task the page ignores taps.

  • Reduce unused CSS

    62 KiB

    About 62 KiB of CSS is downloaded but never applied on this page.

  • Legacy JavaScript

    12 KiB

    Polyfills for old browsers add 12 KiB JavaScript that modern phones do not need.

  • Chained critical requests

    Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

  • Forced reflow

    Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

  • Minify JavaScript

    5 KiB

    5 KiB could be saved by minifying JavaScript.

1 checks passed
  • Server response: 7 ms

    7 ms

    Your server sent the HTML in 7 ms, well inside Google's 600 ms guideline.

Core Web Vitals

5 to fix93
  • Time to Interactive: 15.5 s

    15.5 s

    The page becomes fully interactive after 15.5 s. Good is under 3.8 s.

  • Speed Index: 5.6 s

    5.6 s

    Visually, the page fills in at 5.6 s (Speed Index). Good is under 3.4 s.

  • 27 images without width and height

    27 images have no width and height attributes, so the layout jumps as each one loads.

  • Total Blocking Time: 249 ms

    249 ms

    Scripts block taps and scrolling for 249 ms in total while the page loads. Good is under 200 ms.

  • First Contentful Paint: 2.0 s

    2.0 s

    The first text or image appears after 2.0 s on a phone. Good is under 1.8 s.

  • Not enough real-visitor data yet

    Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

2 checks passed
  • Largest Contentful Paint: 2.3 s

    2.3 s

    Your largest element renders in 2.3 s on a phone, inside Google's 2.5 s “good” threshold. The largest element is the text “Powered By Retailers. Activated By Brands. ‍Measured By Sal…”.

  • Cumulative Layout Shift: 0.002

    0.002

    The layout barely moves while loading (CLS 0.002, good is under 0.1).

Images and page weight

5 to fix43
  • 1 image over 500 KB

    6a8c5f3966ae9bbb1c101a31_ad.png weighs 513 KiB. On a phone connection a single image that size takes seconds.

  • Page weight: 2.9 MB in 122 requests

    2.9 MB

    Your homepage downloads 2.9 MB in 122 requests on a phone: scripts 1.4 MB (46), images 1.1 MB (33) and fonts 245 KiB (6). Under 2 MB keeps phones on slow connections fast.

  • 2 images in older formats

    2 images (608 KiB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

  • 2 images below the first screen load straight away

    2 images further down the page (649 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

  • 1 image far larger than shown

    105 KiB

    1 image is downloaded at several times the size a phone draws it, for example 6a8ce7dec95a6212722488c4_footer-1430x3980303.webp at 2,230 px wide, shown at 358 px. Resized copies would save about 105 KiB.

  • About 0.8 g of CO₂ per visit

    0.82 g

    By the Sustainable Web Design model, a visit to your homepage emits about 0.82 g of CO₂e: 97.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Accessibility

3 to fixGoogle 8895
  • Hidden but focusable

    2 elements hidden from screen readers can still receive keyboard focus.

  • 1 text element with low contrast

    1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

  • 1 link without text

    1 visible link has no text or label, so screen readers cannot say where it goes.

  • Headings skip levels

    Headings skip levels (h2 → h4), which makes the page harder to scan with a screen reader.

2 checks passed
  • Every image has alt text

    All 28 images in the HTML carry an alt attribute.

  • 45 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 49 WCAG 2.2 A/AA and best-practice rules on the phone render: 45 passed and 4 failed. 3 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

2 to fixGoogle 10091
  • No structured data

    No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

  • Meta description is long (367 characters)

    Your meta description is 367 characters; Google truncates after about 160, so the end of your pitch is cut.

  • 35 internal links, 3 external

    The homepage links to 35 pages on surfside.io and 3 external pages.

6 checks passed
  • One H1 headline

    Your main headline reads: “Powered by retailers.Activated by brands.‍Measured by sales.”.

  • Title: 53 characters

    Your title is a healthy 53 characters: “Surfside | The Advertising OS for the Retail Majority”.

  • Canonical URL set

    The canonical URL is https://www.surfside.io/.

  • Open Graph tags complete

    Open Graph tags are complete, so shared links show a title, description and image.

  • robots.txt in place

    robots.txt is in place and points crawlers to your sitemap.

  • XML sitemap found

    Your XML sitemap is reachable at https://www.surfside.io/sitemap.xml.

AI search readiness

1 to fix88
  • No Organization structured data

    There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

  • No llms.txt

    There is no https://www.surfside.io/llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

2 checks passed
  • AI answer engines may read the site

    Your robots.txt lets the crawlers behind ChatGPT search, Claude and Perplexity read the site and cite it in answers.

  • Text is in the HTML

    Your server sends the page's text in the HTML (413 words), so crawlers that don't run JavaScript still read it.

Other pages

2 to fix90
  • 1 page without a meta description

    https://www.surfside.io/casestudies/common-citizen has no meta description, so Google writes the search snippet from whatever text it finds.

  • 1 page without an H1

    https://www.surfside.io/contact has no <h1> headline, so visitors and search engines get no clear main topic.

  • 1 page with very little text

    https://www.surfside.io/contact has under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

  • 15 internal pages checked

    We fetched 15 pages linked from your homepage (of 19 found) and read each the way a search engine does.

5 checks passed
  • Linked pages load

    All 15 pages we checked loaded without an error.

  • Canonical URLs point to themselves

    No page we checked hands its ranking to a different URL.

  • Titles are unique

    Every page we checked has its own title.

  • No linked page is hidden from search

    None of the pages we checked carries a noindex tag.

  • Every page has a title

    All 15 pages that loaded have a <title>.

Best practices

1 to fixGoogle 10093
  • 1 small tap target

    1 of 5 tappable elements near the top of the page is smaller than 24 px, hard to hit with a thumb.

2 checks passed
  • No console errors

    No JavaScript errors were logged while the page loaded on a phone.

  • Mobile viewport set

    The page declares a mobile viewport.

Content and conversion

1 to fix90
  • No direct contact details

    No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

  • No form on the homepage

    There is no form on the homepage, so every lead has to click through to another page first.

  • No risk reducer

    No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

  • About 379 words of copy

    The homepage carries about 379 words of visible text.

4 checks passed
  • Clear next step on the first screen

    On a phone, the first screen shows a clear next step: “BOOK A DEMO”.

  • 3 calls to action

    The homepage has 3 calls to action, for example “Book a demo”, “Get started” and “Contact”.

  • Social proof on the page

    Social proof on the homepage: 13 customer or partner logos and 2 trust badges.

  • Analytics in place

    Analytics detected: Google Tag Manager.

Privacy and tracking

  • 8 trackers load before any consent

    8

    Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, HubSpot and LinkedIn Insight and 3 mores (measured from a US location before any click). A consent tool (HubSpot cookie banner) is installed; check it blocks these until visitors agree where the law requires it.

  • 18 cookies set on arrival

    18

    Opening the homepage sets 18 cookies (measured from a US location before any click).

  • 35 other companies contacted

    Loading the homepage contacts 35 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.

1 checks passed
  • Consent tool: HubSpot cookie banner

    A consent management tool (HubSpot cookie banner) loads with the page.

Security, domain, email and software versions

The security, domain and email checks, software and plugin versions, and any app with a known security problem are visible only to people at surfside.io, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
