Speed results

75%

Your Speed test score is okay but you can definitely make some simple changes to help improve your score further.

A slow page will cause your visitors to move on and go elsewhere and, importantly, Google will penalize your search ranking if your page fails to perform in against this Core Web Vitals test.

We found 11 opportunities for you to improve your Speed score

Why page speed matters

Page speed is a critical factor in getting your page ranking higher in Google search engine results pages (SERPS). If your website isn't on par with the top 10 organic pages, you won't stand much of a chance of ranking on the first search results results page.

Since 2010, Google has used site speed as a ranking factor and they confirmed it as a landing page factor in 2018.

And it's now more important than ever to get your page in good shape as Google continues to refine and adjust the format and source of the results it shows on the first page. You'll have noticed paid ad panels, local results panels, rich snippets and other elements all encroaching on space that was once reserved for organic search results.

How to improve your site speed

Your site was tested using Google Page Speed Insights tool which provides detaled analysis of all the important factors affecting your page speed. The following detailed test results give you pointers to what's impacting your current site speed and how you can improve things.

Your site was tested for speed performance on a Mobile device. This is because, according to Statcounter, mobile devices are now the dominant medium for internet access. If you optimize for mobile, it follows that desktop performance will also be improved.

Your page speed test results

Speed Index
9%
Your page takes over 5.8 seconds to load which means that you need to improve your page speed by addressing some of the items highlighted in the rest of this Speed audit. Speed Index shows how quickly the contents of a page are visibly populated. Learn more.
DOM size
100%
Great, your page doesn't have an excessively large number of HTML elements.
Total Byte weight
100%
Your page doesn't have any resources which are really large, good job!
Server response time
100%
Excellent, your server responded in less than 600ms.
Redirects
40%
Redirects introduce additional delays before the page can be loaded. Learn more.
Uses text compression
88%
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes. Learn more. You should use Brotli compression with GZIP as a fallback to achieve the optimum compression. This guide provides example configurations for common servers. Note: this is not the same as minification - some of the files listed below may be minimized but further server-side compression would create additional savings.
Render blocking resources
88%
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles. Learn more.
Bootup time
77%
Your page's JavasScript takes between 2 and 3.5 seconds to execute. Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this. Learn more.
Time to interactive
15%
Your page takes 12.4 seconds to become fully interactive. That makes for a bad user experience so you should definitely take action to improve this score. Reducing your JavaScript execution time is usually a good first step to improving this. Time to interactive is the amount of time it takes for the page to become fully interactive. Learn more.
Uses long cache Time To Live
50%
A long cache lifetime can speed up repeat visits to your page. Learn more. You should leverage caching because it will help improve page load times by preventing the browser from having to refetch static contenet every time a users visits your site.

Security results

21%

You need to make a number of critical Security improvements to your page as soon as possible.

Incidents of website hijacking and data breaches are growing daily and hackers are increasingly targeting small business websites as larger corporations get their security sorted. The changes you need to make are simple but they'll address the most common vulnerabilities as defined by the Open Web Application Security Project (OWASP) standard.

We found 7 opportunities for you to improve your Security score
Note: this report does not include all the detailed optimization guidance that you would get in your paid report.

Why site security matters

There are endless website hacking statistics published on the internet which, in itself, should be a trigger for action to any website owner. For example, according to Forbes, even way back in 2013 there were an average of 30,000 websites hacked every day. Incredibly, 56% of all internet traffic is from automated sources like hacking tools, site scrapers, spammers, impersonators and bots.

And because large corporates have had to tighten up their website security, it's small and medium size business' websites which have increasingly become a target for hackers.

Securing your small or medium size business' website is, of course, only one aspect of cyber security that you need to implement. But, it's shockingly true to say that a huge proportion of websites don't have even the most basic security measures in place.

Security matters for search engine ranking too; since 2018, Google has been penalising websites without SSL (HTTPS) enabled. So not only are those sites insecure but they'll also rank less highly in the search engine results pages.

How to improve your site security

Your site was tested against the top ten risks as defined by the Open Web Application Security Project (OWASP) Secure Headers Project. This project defines the current best practice standard for protecting your website's vulnerability against hackers.

These measures are easily implemented and are fundamental security precautions which protect your site. The theory is that if you make your website that bit harder to hack, the hackers will quickly move on to an easier target.

Your site security audit test results

Safe browsing blacklist check
83%
Google, McAfee and Norton Antivirus all maintain website blacklists which are used to flag risky websites to their users. If your site is on one of these lists, then both your website traffic and, potentially, your business reputation, will be impacted.
  • Your page is not blacklisted by Google.
  • Your page is not blacklisted by McAfee.
  • We couldn't get your site's Norton Safe Web rating. You can check your site status here.
Strict Transport Security (HSTS)
0%
Your site is insecure : HSTS isn't enabled. The Strict-Transport-Security (HSTS) is a response header that improves security by instructing browsers to always use https:// instead of http:// when visiting your site. Find out more about Strict-Transport-Security here.
X-Frame-Options
0%
Your site is insecure : the X-Frame-Options header isn't set; the site is vulnerable to clickjacking attack. HTTP response headers can be used to indicate whether or not a browser should be allowed to render a page in a <frame> or <iframe>. Find out more about X-Frame-Options here.
X-XSS-Protection
100%
Your site is secure : the X-XSS-Protection header has been deprecated by modern browsers so doesn't need to be set.
X-Content-Type-Options
0%
Your site is insecure : browsers are vulnerable to the content sniffing attack. Find out more about X-Content-Type-Options here. Setting this header will prevent the browser from interpreting files as a different MIME type to what is specified in the X-Content-Type-Options header.
Server
0%
Your site is insecure : browsers may be able to tell which server technology your website is running on. That might make it easier for hackers to exploit known vulnerabilities with that technology. It's usually best to hide that information by explicitly unsetting the Server header.
X-Powered-By
100%
Secure : the website is hiding information about the scripting language your website is running on.
Content-Security-Policy (CSP)
0%
Your site is insecure : the Content-Security-Policy header isn't set so the page might be vulnerable to a wide range of attacks, including cross-site scripting and other cross-site injections. Find out more about Content-Security-Policy here. The Content-Security-Policy tells the browser where resources are allowed to be loaded and if it's allowed to parse/run inline styles or Javascript. This is important because it prevents content injection attacks, such as Cross Site Scripting (XSS).

WARNING: Setting up a Content-Security-Policy is a complex undertaking and, if you get it wrong, can break your site. Use Content-Security-Policy-Report-Only to debug your Content-Security-Policy until no errors are reported in the console.
X-Permitted-Cross-Domain-Policies
0%
Your site is insecure : the X-Permitted-Cross-Domain-Policies header isn't set. A cross-domain policy file is an XML document that grants a web client, such as Adobe Flash Player or Adobe Acrobat (though not necessarily limited to these), permission to handle data across domains. Find out more about X-Permitted-Cross-Domain-Policies here.
Referrer-Policy
0%
Your site is insecure : the Referrer-Policy header isn't set. That means there is no policy for sending Referrer header information when performing a same-origin or cross-origin requests. Find out more about Referrer-Policy here.

Why on-page search engine optimisation matters

There are almost 2 billion websites on the internet today and people rely on search engines when they want to find information or services. So, in order for your website to be found amongst all those millions of other sites, your page's search engine optimization - or SEO - is more important than ever.

To be successful in organic search means your site has to be optimized for a combination of factors which search engines consider important – technical, on-page and off-page. Off-page techniques – such as link building – receive a lot of attention on the web and of course they're really important but, off-page SEO won't be enough if you don’t pay attention to the fundamentals and get your on-page SEO right.

On-page SEO is important because it helps search engines understand your website and its content, as well as identify whether it is relevant to a searcher's query. So, in addition to publishing relevant, high-quality content, on-page SEO includes optimizing things like your headlines, HTML tags (title, meta, and header), and images.

How to improve your Search Engine Optimization score

Your site was tested for over 20 of these on-page SEO fundamentals and the detailed results below will tell you where, and how, you might need to make some changes to improve your score.

Your on-page Search Engine Optimization results

0%
There is no robots.txt file found at https://bilibili.com/robots.txt. You need to add a robots.txt - find out more and how to create one, over at Google.
Sitemap.xml
100%
Excellent, there is a Sitemap file found at https://bilibili.com/sitemap.xml.
URL format
100%
The URL is well formatted, so search engines will like it!
Page language
100%
Page language: ChineseGreat, the page has at least one lang attribute set to inform browsers what the language of the content is: Chinese.
Robots meta tag
100%
The page doesn't have a <meta name="robots" content="..." /> tag set so it is indexable by search engines, which is good!
Page title
25%
The page <title> could be longer. It's 45 characters so you could add up to 20 more characters to bring it up to the recommended maximum of 65 and make the most of the available title space.
Page description
100%
Great job, the page <meta name="description" ... /> is about the right length, at 163 characters, to be correctly displayed in search engine results pages.
Open Graph meta tags
0%
Adding Open Graph tags to your website won’t directly affect your on-page SEO, but it will influence the performance of your links on social media, so that means it's worth adding them.
Canonical URL
0%
No canonical link meta tag found on your page. You should add a cannonical link meta tag to control how duplicate content pages are treated by search engines.
Scaling for mobile devices
0%
Mobile page scaling properties are not set via the Viewport meta tag.
Valid HTML
95%
The page HTML has 1 errors or warnings that you should review and/or fix.
Page content
0%
The page content word count is low at 222 (excluding 7 common "stop words"). Consider adding more content to take the word count to at least 300 and avoid the page being classed as having 'thin content' by search engines.
H1 page heading
100%
The page is missing a <h1> heading. A unique <h1> heading for each page is really important to help your visitors, and search engines, understand what your page is about. In Aug-21 Google announced that they'd made a change to the way in which they generate titles for search results pages - they provided a further update in Sep-21. They've switched focus from using the <title> content to using the <h1> heading. The article doesn't make it absolutely clear what criteria will be used or how long the heading should be, so the recommendations here are provisional.
H2 subheadings
0%
No <h2> page subheadings found. A well structured page should probably have at least one <h2> subheading in the <body> section of your page to break up the content.
Other subheadings
0%
No other page subheadings were found. A well structured page should probably have at least one other <h3>, <h4>, <h5> or <h6> subheading to break up the content.
Image ALT tags
56%
The alt text attribute is missing from 14 of the 32 images found on the page. You should add the alt attribute on every img tag to describe the image - it's also a great way to boost SEO by strategically including your target keywords.
Plugins
100%
Great, there were no plugin tags found on the page.
Broken links
100%
There are 185 links on the page - 177 internal, 8 external - and all of them worked ok, good job!
Nofollow internal links
100%
There are no nofollow issues with any internal links on the page, well done.
Nofollow external links
0%
There are nofollow issues with 8 external links on the page. Unless those external pages are subdomains of your main site, you should probably include the <a rel="nofollow noopener noreferrer" ... /> attribute on external links to prevent search engines transferring PageRank or anchor text across these links and away from your page. It's good practice to include noopener and noreferrer alongside nofollow to help improve security by ensuring the link doesn't grant the new page access to the document that opened it.
Keyword analysis
35%
The top 5 frequently-occurring words found in your page content - 万播放, , vs, 资讯, 单机游戏 - don't all appear in your page <title>, <meta name="description" content="..." />, <h1> header or <img alt="" ... /> tags. If these words are the ones you're trying to rank this page for, then you should consider using them across all these tags. If they're not the keywords you're trying to rank the page for, then you should review the page content and, without keyword stuffing, adjust the occurrences of your target keywords. The next 5 most common keywords are also listed for your information.
URL is indexed in Google
100%
This page is indexed by Google, that's good news.
Google My Business presence
100%
Great, there is a presence for this website on Google My Business.
