conferenceseries.com website review

9 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.1 s.

21 images could be 17.7 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

59 files are served with short cache lifetimes, so returning visitors download them again (12.3 MB).

8 third-party services load with your homepage (Google Tag Manager, Other Google APIs/SDKs and Facebook and others), adding 18.4 MB and 377 ms of main-thread time.

omicsgroup.com costs a phone 35 ms of main-thread work and 17.8 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.

Your mobile performance score is 83. Pages that score under 90 lose visitors before the first paint.

About 314 KiB of JavaScript is downloaded but never used on this page.

7 long tasks block the main thread while loading, the longest for 134 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 100 ms).

Polyfills for old browsers add 23 KiB JavaScript that modern phones do not need.

About 19 KiB of CSS is downloaded but never applied on this page.

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.

Real visitors wait 4.5 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 4.7 s (75th percentile). Good is under 1.8 s.

Real visitors wait 3.1 s for your server to start answering (75th percentile). Good is under 800 ms.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 3.8 s to 4.1 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

The page becomes fully interactive after 7.2 s. Good is under 3.8 s.

Your largest element takes 3.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Meet Inspiring Speakers and Experts at our 3000+ Global Con…”.

The layout shifts by 0.123 while loading, so content jumps under the reader's thumb. Good is under 0.1.

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

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 153 ms to 139 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 18.6 MB in 87 requests on a phone: images 17.9 MB (49), scripts 500 KiB (13) and fonts 130 KiB (4). Under 2 MB keeps phones on slow connections fast.

18 images are downloaded at several times the size a phone draws them, for example img_7639-1717070075-1726562387.jpg at 5,472 px wide, shown at 104 px. Resized copies would save about 17.3 MB.

2 images weigh 14.5 MB together. On a phone connection a single image that size takes seconds.

20 images (17.7 MB) 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.

20 images further down the page (17.7 MB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 5.26 g of CO₂e: 631.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

15 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

1 link inside paragraphs relies on colour alone to stand out.

All page content should be contained by landmarks: 43 elements on the page fail this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

5 form fields have no label, so screen readers announce an empty box and autofill guesses.

Headings skip levels (h1 → h3, h2 → h4 and h2 → h4), which makes the page harder to scan with a screen reader.

Your title is 68 characters, so Google will cut it off around 60: “Conference Series : International Scientific and Medical Conferences”.

Your meta description is 178 characters; Google truncates after about 160, so the end of your pitch is cut.

Structured data found (Organization) but with 1 problem, for example “Organization: missing name”.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

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

The homepage links to 207 pages on conferenceseries.com and 53 external pages.

Your Organization JSON-LD is missing name, sameAs (social profiles), description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

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.

Your homepage links to /canada-meetings, /brazil-meetings, /australia-meetings, /china-meetings, /hong-kong-meetings and /india-meetings and 9 others, which answer with an error. Visitors hit a dead end and search engines drop them.

We fetched 15 pages linked from your homepage (of 100 found) and read each the way a search engine does.

37 of 89 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

3 errors were logged to the browser console while the page loaded, for example “Access to XMLHttpRequest at 'https://www.omicsgroup.com/conferences/ACS/confassets/cs/css/ekko-lightbox.min.css' from o…”.

22 images are displayed at the wrong aspect ratio, so they look stretched or squashed.

1 image is served at too low a resolution for sharp phone screens.

15 links from your homepage to your own site are broken, for example https://www.conferenceseries.com/canada-meetings (500).

No Content-Security-Policy header, the main browser-side defence against injected scripts.

Neither X-Frame-Options nor a CSP frame-ancestors policy is set, so any site can embed yours in a frame.

HSTS is set, but max-age is 180 days; one year is the recommended minimum.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

conferenceseries.com has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

conferenceseries.com's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

The homepage shows no opening hours. If customers visit or call, show when.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

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

The homepage carries about 688 words of visible text.

DMARC is set to p=none, so mail pretending to be conferenceseries.com is still delivered. Reports are on, so moving to quarantine is the next step.

We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager and Meta Pixel (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

Opening the homepage sets 4 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.

Loading the homepage contacts 18 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
