Lighthouse SEO and performance scores
01

Lighthouse scores that drive rankings

Performance, accessibility, SEO, and best practices

Google ranks sites based on Core Web Vitals. We run Lighthouse audits automatically and alert you when scores drop, so your clients stay visible in search results.

When a plugin update or content change tanks performance, you catch it before Google does, and before traffic drops.

02

Page speed that converts

Slow sites lose visitors and sales

Every 100ms of load time costs conversions. We track response times across all client sites and alert you when performance degrades, so you can fix it before bounce rates spike.

Set performance budgets per page and get notified when they're exceeded. Great for landing pages where speed directly impacts campaign ROI.

Uptime during campaigns

Nothing kills a campaign like downtime

You've spent the budget driving traffic. The ads are running. And the site goes down. We check every minute from multiple locations so you know instantly when something breaks.

Get alerted before clients do, and have the timeline ready when they ask what happened.

Broken links hurt SEO

Catch 404s before search engines do

Broken links tank search rankings and frustrate visitors. We crawl client sites daily and flag dead links, missing images, and mixed content warnings before they impact SEO.

Especially valuable after content updates, CMS migrations, or when managing sites with lots of internal linking.

Reports clients actually read

Prove value without extra meetings

Send automated monthly reports with uptime, performance trends, Lighthouse scores, and broken link fixes. Clients get a clear summary of what you prevented, not just what broke.

Use reports to justify retainers and show the ongoing value of your work.

SSL and domain expiration

Browser warnings kill trust instantly

An expired SSL certificate shows a scary browser warning. An expired domain loses all its SEO equity. We monitor both and alert you well before anything lapses.

Especially important when managing domains and certificates across multiple client accounts.

07

Status pages for client communication

One place for incident updates

When something breaks during a campaign, clients need to know what's happening. Give each client a branded status page so they can see updates without flooding your inbox.

Clear communication during incidents builds trust and reduces panic.

Frequently asked questions

Target rings Target rings

Google uses Core Web Vitals as a ranking factor. Slow-loading pages, layout shifts, and poor interactivity can push your clients down in search results. Oh Dear runs automated Lighthouse audits and alerts you when performance scores drop, so you can fix issues before they impact rankings and organic traffic.

Yes. Oh Dear sends automated monthly reports with uptime percentages, performance trends, Lighthouse scores, and broken link fixes. You control who receives them: send reports to yourself to review first, or deliver them directly to clients. Either way, they help demonstrate ongoing value and justify maintenance retainers without manual work.

We check every minute from multiple global locations. When downtime is detected, you get an alert within 60-90 seconds via Slack, email, SMS, or your preferred channel. You'll know about the problem before clients do and have the timeline ready when they ask what happened.

Broken links signal poor site quality to search engines and frustrate visitors. Oh Dear crawls client sites daily and flags dead links, missing images, and mixed content warnings. This is especially valuable after CMS migrations or content updates when links often break silently.

Absolutely. Oh Dear is built for agencies managing many sites. You can organize sites with tags, set different alert recipients per client, and view performance across your entire portfolio at a glance. One dashboard replaces juggling multiple monitoring tools.
