sfgate.com website review

203 files are served with short cache lifetimes, so returning visitors download them again (8.3 MB).

A phone's processor spends 14.6 s on main-thread work while loading, 8.7 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Your mobile performance score is 28. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

8 third-party services load with your homepage (Google Tag Manager, Rubicon Project and ex.co and others), adding 7.7 MB and 2.6 s of main-thread time.

About 2.2 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 940 ms faster on a phone.

ex.co costs a phone 318 ms of main-thread work and 6.1 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.

Google Tag Manager costs a phone 773 ms of main-thread work and 746 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.

20 long tasks block the main thread while loading, the longest for 666 ms. During a long task the page ignores taps.

Rubicon Project costs a phone 446 ms of main-thread work and 125 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.

Facebook costs a phone 253 ms of main-thread work and 293 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.

Amazon Ads costs a phone 259 ms of main-thread work and 218 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.

The page has 2,352 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Polyfills for old browsers add 107 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 150 ms.

78 KiB could be saved by minifying JavaScript.

3 images could be 73 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

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

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

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

Your largest element takes 12.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “San Francisco 49ers wide receiver Mike Evans reacts after m…”.

Visually, the page fills in at 27.7 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 73.4 s. Good is under 3.8 s.

Scripts block taps and scrolling for 2.3 s in total while the page loads. Good is under 200 ms.

The first text or image appears after 4.0 s on a phone. Good is under 1.8 s.

For real visitors the layout shifts by 0.12 (75th percentile). Good is under 0.1.

Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' largest content (lcp) went from 1.2 s to 1.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

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

Your homepage downloads 13.7 MB in 1,262 requests on a phone: scripts 5.5 MB (193), media 5.4 MB (28) and images 1.5 MB (286). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 3.88 g of CO₂e: 466.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 button has no accessible name, so screen readers announce just “button”.

All page content should be contained by landmarks: 6 elements on the page fail this check, rated moderate by axe-core.

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

No meta description, so Google writes its own snippet from whatever text it finds.

There is no <h1>, so neither visitors nor Google get a clear main headline.

Your title is only 16 characters: “Client Challenge”. Between 30 and 65 characters leaves room to say what you do and for whom.

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

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

No XML sitemap at https://www.sfgate.com/sitemap.xml, so Google discovers your pages only by following links.

The homepage links to only 0 pages on your own site, so visitors and crawlers find few routes into the rest of it.

No favicon is declared in the HTML, so browser tabs and Google's mobile results may show a generic icon.

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

Your robots.txt shuts out Claude (Claude-User), Perplexity (PerplexityBot) and Perplexity (Perplexity-User). These fetch pages to answer people's questions and cite the source, so your site can't be quoted or linked in those answers.

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.

There is no /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.

robots.txt blocks ClaudeBot, Applebot-Extended and CCBot, which collect pages to train models. That's a legitimate choice and doesn't by itself stop the site appearing in AI answers.

42 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

The page uses 2 deprecated browser APIs that will stop working in future browsers (“Unload event listeners are deprecated and will be removed.”).

2 errors were logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 401 ()”.

Chrome logged issues while loading the page (“Mixed content”).

Requests the notification permission on page load.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

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

The homepage has only about 35 words of visible text; thin pages give Google and first-time buyers little to go on.

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

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

Opening the homepage sets 6 cookies (measured from a US location before any click).

No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.
