What website performance issues can caching solve

Without a dedicated cache service, every request affects your origin server. Slow responses may cost you crawl frequency, rankings, and conversions before you have a chance to react.

Bots crawl fewer pages without a cache

Search engines distribute a crawl budget based on how fast servers respond. Without cache, pages can take much longer to load, so Googlebot inspects fewer URLs per visit.

Cache misses serve errors instead of content

When a cache entry expires during a traffic spike or a rendering job fails, the request falls through to an overloaded origin, often returning a 5xx error to the bot or user that triggered it.

Origin servers absorb full traffic load

Every bot request, traffic spike, and re-crawl hits servers directly. Without a cache absorbing repeated requests, infrastructure costs increase and response times degrade under load.

One cache TTL doesn't fit all pages

Without per-page or per-pattern TTL rules, you have to choose between serving outdated content too long or invalidating the entire cache. Neither is acceptable for large sites.

Proactive cache warming

EdgeComet does not wait for a bot to explore an empty cache. Pages are retrieved, rendered and cached in advance from your sitemap, Search Console reports, and crawl patterns.

  • Recache the pages that bots return to Warming is caused by real crawl, so capacity goes where bots go
  • Use the webhook API to push on-demand updates A deploy or a price change invalidates exactly the URLs it impacted
  • Execute urgent and automated jobs in a single prioritized queue A launch is always ahead of the archive refresh

Smart refreshing and invalidation

Freshness is determined per page. Frequently updated pages and content earning clicks in Google and AI answers refresh every day or more quickly.

  • Update rate follows how frequently content changes EdgeComet compares each render against the previous version
  • URLs earning organic traffic earn priority Search Console data defines the refresh queue
  • Override any URL pattern with an explicit TTL Listings in minutes, editorial in hours, legal pages in weeks
  • A failed refresh is covered by a stale fallback A bot receives the last good version instead of a 5xx
Cache panel with renders avoided, hit rate, cache age distribution, and cache efficiency by bot
Inspect

Full cache visibility

You can open the cache and read it. Every cached page, the exact HTML each bot got, when it was stored, what changed since the previous version, and hit and miss rates over time.

  • Discover HTML for any URL View the title, canonical, and structured data a bot was shown
  • Check what changed between cached versions Learn when a title or canonical moved, and during which render it occurred
  • Track hit and miss rates per bot and per section Find the website parts where bots reach your origin
  • Confirm coverage before you rely on it Validate behavior on live traffic before you switch over
Cache diagnostics panel with pages affected, unique issues, total occurrences, and issue trend over time

Why teams switch to EdgeComet

EdgeComet keeps copies of your content so search engine bots always receive a fast response. Control how fresh your pages are, without involving developers to make changes.

Traditional cache tools are built for humans, not bots.

You get pages fast, but bots still hit slow servers and errors.

EdgeComet shows which pages bots got from cache and which are missed.

Most CDNs cache content the same way.

They don't allow you to create different rules for different pages.

EdgeComet allows users to set cache duration per URL.

Most tools serve bots from the same infrastructure as for users.

When the server is under load, bots get errors.

With EdgeComet, even when your pages are outdated, bots never see errors.

Benefits of faster content delivery

EdgeComet’s website cache service for faster loading doesn't just improve page speed. It increases crawl frequency, protects your origin, and ensures bots always get full content.

Increase crawl frequency by responding faster

Search engines factor response time into how often they crawl your pages.

Increase the number of URLs Googlebot, Bingbot, and AI bots can process in a single session.

Outcome
Faster URL discovery and higher crawl rates

Protect your origin from traffic spikes

All repeat bot and user requests are served from cache without ever reaching your application servers.

Traffic spikes, crawl surges, and high-traffic news cycles are absorbed entirely by the cache layer, keeping your origin stable and your users unaffected.

Outcome
Origin server stability during intense traffic

Eliminate 5xx errors for crawlers and users

The stale fallback ensures that when fresh content isn't available, the last valid cached version is served instead of an error.

Bots never encounter a 5xx, crawl budget is preserved, and users see content rather than a failure page.

Outcome
100% uptime and saved crawl budget

Control content freshness at the page level

Variable TTL rules let you define how long each type of page stays cached.

Cache behavior matches your publishing workflow rather than fighting it.

Outcome
Optimized content freshness across all pages

How website cache service works best

A website caching service keeps copies of rendered pages and serves them to subsequent requests, eliminating the need to re-render the same content for every visit. Here's how EdgeComet's cache works in practice:

Cache Hit

Subsequent requests for the same URL are served directly from memory in under 15ms, without touching your origin server.

TTL Expiration and Recache

Expired entries are refreshed automatically, proactively, or on demand, keeping high-priority content fresh, with stale fallback if recaching fails.

Cache Analytics

Hit rates, miss rates, and per-URL freshness are monitored in real time for full visibility into cache performance.

Where bot load hurts most

Websites with extensive catalogs, regular changes, and high crawler interest are the ones where a web cache service for website performance pays for itself the quickest

E-Commerce

Category pages, filtering, and internal search cost the most to build and bots request them the most. EdgeComet gets that bot traffic first, so a flash sale never competes with a crawl surge for the same database.

Classifieds

Classifieds have countless listings that don't last long, yet bots keep returning to check them. EdgeComet refreshes active listings often and archived ones rarely, without affecting your servers.

Real Estate

Availability and pricing move daily while neighborhood guides and agency profiles don’t change for months. Freshness follows each page's own change rate instead of one site-wide TTL.

Publishers

Googlebot, news crawlers and every AI training bot arrive at once on a story that just broke. The cache takes that traffic while your CMS gets on with publishing the next one.

All your questions answered

A cloud caching solution for websites keeps rendered web content and serves it to subsequent requests without touching the origin server. Instead of re-rendering a page on every visit, the cache delivers a pre-built response.

Any site where content is requested often by multiple bots or users can benefit from a cache layer. It's important when rendering is slow or when the crawl budget is being wasted on slow responses.

EdgeComet's TTL rules allow dynamic pages to be cached for a few minutes, which is enough to absorb repeated bot visits while keeping content fresh. For pages that must never be cached, URL exclusions can be configured.

You can improve site speed with web cache service provided by EdgeComet. The solution gives responses in under 15ms compared to 1–3 seconds for uncached server responses and 100–500ms for basic CDNs. For bots, faster response times increase crawl frequency. For users, lower time-to-first-byte enhances Core Web Vitals.

EdgeComet works as a separate tool outside your site. No changes required to application code, server configuration, or CDN cache service setup. Deployment takes days, and shadow mode lets you verify cache behavior on live traffic.

EdgeComet can be deployed in shadow mode, so you can validate hit rates, TTL behavior, and coverage before switching traffic over. From there, full activation is a configuration change, not a code deployment.
