Title Tag
前端百科 - Web前端百科全书
Length: 16 character(s) (208 pixels)
Your HTML title tag appears in browser tabs, bookmarks and in search result pages.
Make your title tags clear, concise (65 characters, 200-569 pixels) and include your most important keywords.
Check the title tags for thousands of pages at once using Site Crawl.
Meta Description
Web前端百科全书,系统整理Web前端开发领域知识体系,供开发者系统学习交流Web前端开发技术。
Length: 48 character(s) (588 pixels)
Great, your meta description contains between 70 and 160 characters spaces included (400 - 940 pixels).
A good meta description acts as an organic advertisement, so use enticing messaging with a clear call to action to maximize click-through rate. They allow you to influence how your web pages are described and displayed in search results.
Ensure that all of your web pages have a unique meta description that is explicit and contains your most important keywords (these appear in bold when they match part or all of the user’s search query).
Use WooRank's Site Crawl to check thousands of pages for meta descriptions that are too long, too short or duplicated across multiple web pages.

Search engines may create their own titles and descriptions if they are missing, poorly written and/or not relevant to the content on the page and cut short if they go over the character limit. So it’s important to be clear, concise and within the suggested character limit.
Check your title tag and meta description to make sure they are clear, concise, within the suggested character limit and that they convey the right message to encourage the viewer to click through to your site.

Great, your website is structured using HTML headings (<H1> to <H6>).
Use your keywords in the headings and make sure the first level (<H1>) includes your most important keywords. Never duplicate your title tag content in your header tag.
While it is important to ensure every page has an <H1> tag, only include more than one per page if you're using HTML5. Instead, use multiple <H2> - <H6> tags.
missing translation: en.headings_contentContent Analysis
This data represents the words and phrases that your page appears to be optimized around. We use what’s called “natural language processing" (NLP), which is a form of artificial intelligence that allows computers to read human language, to do this analysis.
The numbers next to each word or phrase represents how often we detected them and their variants on the page.
Are these the keywords you want to target for your page? If so, great! Track your site’s rankings in Google search results using WooRank’s Keyword Tool.
If these keywords aren’t relevant to your page, consider updating your content to optimize it for your target keywords.
Alt Attribute
Alternative text allows you to add a description to an image. Since search engine crawlers cannot see images, they rely on alternative text attributes to determine relevance to a search query. Alternative text also helps makes an image more likely to appear in a Google image search and is used by screen readers to provide context for visually impaired users.
It looks like most or all of your images have alternative text. Check the images on your website to make sure accurate and relevant alternative text is specified for each image on the page.
Try to keep your alternative text to a simple, one-sentence description of what's in the image.

Links pass value from one page to another. This value is called 'link juice'.
A page's link juice is split between all the links on that page so lots of unnecessary links on a page will dilute the value attributed to each link. There's no exact number of links to include on a page but best practice is to keep it under 200.
Using the Nofollow attribute in your links prevents some link juice, but these links are still taken into account when calculating the value that is passed through each link, so using lots of NoFollow links can still dilute PageRank.
Check your site's internal linking using Site Crawl.
Language
Declared: Missing
Detected: Chinese
Your website hasn't specified a language yet. Use the META Language Attribute to declare the intended language of your website. We've detected that your website is currently in Chinese.
Here are some tips for multilingual websites:
- Define the language of the content in each page's HTML code.
- Specify the language code in the URL as well (e.g., "mywebsite.com/fr/mycontent.html").
- Use hreflang tags to specify language and country for Google, and the "content-language" meta tag to specify the language and country for Bing.
Web Feeds
We found 1 web feed URL(s) on this web page.
URL | Format |
---|---|
https://f2er.info/rss | RSS |
Web Feeds can be used across a network of websites for product alerts, news, blog updates and more. Users can choose to subscribe to your content and receive notifications. Most multimedia content available on the web can be easily and efficiently distributed to your users using feeds.
The content would be delivered to the user in either RSS, ATOM, or JSON format. The aggregation of a web feed is the act of making a collection of web feeds available on one page.
Adding a web feed depends on the CMS you're using. Check with your CMS for specific instructions. You can also check this tutorial on creating RSS feeds for your website. Once it's added, start advertising it on your pages.

https://www.f2er.info/ | ETIMEDOUT |
Search engines see www.f2er.info and f2er.info as two different websites with the same content. This causes them to see a lot of duplicate content, which they don't like.
Right now your website is not directing traffic to www.f2er.info and f2er.info to the same URL. It is crucial that you fix this.
Use the rel="canonical" tag to tell search engines which is the definitive version of your domain. Use a 301 redirect to divert traffic from your secondary domain.
This issue can be caused by problems with a website's SSL configuration. Check your site's SSL configuration for any errors.
If you need help resolving issues with your SSL configuration, consider using a professional service to set it up for you.
Robots.txt
A robots.txt file allows you to restrict the access of search engine crawlers to prevent them from accessing specific pages or directories. They also point the web crawler to your page’s XML sitemap file.
Your site currently has a robots.txt file. You can use Google Search Console's Robots.txt Tester to submit and test your robots.txt file and to make sure Googlebot isn't crawling any restricted files.
See the pages you've disallowed with your robots.txt file with Site Crawl.
XML Sitemap
We checked the robots.txt file for f2er.info but couldn't find an XML sitemap. Specifying the location of your XML sitemaps in your robots.txt file ensures that search engines and other crawlers find and access it easily each time they access your website.
Learn more about adding your XML sitemap to your robots.txt file.
If you haven't created a sitemap yet, we recommend you generate one for your site and submit it through both Google Search Console and Bing Webmaster Tools. Usually, your XML sitemap would be found at f2er.info/sitemap.xml
Make sure to only include the pages you want search engines to crawl, so leave out any that have been blocked in a robots.txt file. Avoid using any URLs that cause redirects or error codes and be consistent in using your preferred URLs (with or without www.), correct protocols (http vs. https) and trailing slashes. missing translation: en.xml_sitemaps_contentURL Parameters
Use the URL Parameters Tool in Google Search Console to tell Google how your URL parameters affect page content and how to to crawl URLs with parameters. Use this tool very carefully - you can easily prevent Google from crawling pages you want indexed through overly restrictive crawling settings, especially if you have URLs with multiple parameters.
Check the On-Page section of Site Crawl to identify any duplicate content issues.
Hreflang Tags
If your website targets users all around the world, using hreflang tags will help make sure the right content is being served to the right users.
The value of the hreflang attribute identifies the language (in ISO 639-1 format) and optionally a region in ISO 3166-1 Alpha 2 format of an alternate URL.
Use WooRank's Site Crawl to perform a thorough check on hreflang validity across a website.
Underscores in the URLs
Great, you aren't using underscores (these_are_underscores) in your URLs.
Google sees hyphens as word separators while underscores aren't recognized. So the search engine sees www.example.com/green_dress as www.example.com/greendress. The bots will have a hard time determining this URL's relevance to a keyword.

Mobile Friendliness
Mobile friendly pages make it easy for users to complete objectives and common tasks and use a design or template that is consistent across all devices (uses responsive web design).
Your site is well configured for mobile users.
missing translation: en.mobile_friendliness_contentMobile Rendering
This is how your website appears when displayed on different mobile devices.
With more than half of all Google search queries originating on a mobile device, it is important to make sure your mobile site is optimized for these users.

The average fingertip area is 48 pixels in width and height, so yourTap targets should be spaced enough for the average user to click something on your site without accidentally clicking a nearby link. The minimum required space between tap targets is 8 pixels on each side.
Use Google's Lighthouse tool to get a detailed look at all of your tap targets that are too small and too close together.
If sizing isn't an issue, check that you have set your mobile viewport meta tag, which defines where your content appears. If it's not set, your tap targets could overlap each other and become difficult and frustrating to use for your mobile users.

Structured Data
Schema.org
Schema.org is a set of vocabularies used to add meaning to the information on a webpage in a way that is readable by machines (Google). Schema.org vocabularies include attributes for entities, relationships between entities and actions.
Learn more in Google's intro to structured data. Structuring data on your pages can help increase website traffic and improve audience engagement. Schema.org vocabulary can be added to a page using many different formats, including RDFa, Microdata and JSON-LD.Schema.org is a collaborative, community activity with a mission to create, maintain, and promote schemas for structured data on the Internet, on web pages, in email messages, and beyond.
Schema.org vocabulary can be used with many different encodings, including RDFa, Microdata and JSON-LD. These vocabularies cover entities, relationships between entities and actions, and can easily be extended through a well-documented extension model. Over 10 million sites use Schema.org to markup their web pages and email messages. Many applications from Google, Microsoft, Pinterest, Yandex and others already use these vocabularies to power rich user experiences.

Email Privacy
We don’t recommend adding plain text/linked email addresses to your webpages, as malicious bots scrape the web in search of email addresses to spam. Instead, consider using a contact form.
SSL Secure
Great, your website is SSL secured (HTTPS).
While switching to HTTPS, make sure your site remains optimized and see to it that your website will still run quickly. Follow these best practices for a smooth transition:
- Use a serious issuer to purchase your SSL certificate
- Redirect all of your HTTP pages to the HTTPS version of your website
- Use HTTP Strict Transport Security (HSTS) in your headers
- Renew your SSL certificate every year, before it expires
- Make sure that all of your content (CSS, etc.) is linked to HTTPS
- Update your XML sitemap to ensure the URLs include HTTPS and update the robots.txt file to reference this version
- Register the HTTPS website in Google & Bing Search Console/Webmaster Tools
- Use a serious issuer to purchase your SSL certificate
- Redirect all of your HTTP pages to the HTTPS version of your website
- Use a Security Token Service (STS) in your headers
- Renew your SSL certificate every year, before it expires
- Make sure that all of your content (CSS, etc.) is linked to HTTPS
- Update your XML sitemap to ensure the URLs include HTTPS and update the robots.txt file to reference this version
- Register the HTTPS version of the website in Google & Bing Search Console/Webmaster Tools

Server Uptime
Server IP
121.42.51.172
Your server's IP address has little impact on your SEO. Nevertheless, try to host your website on a server which is geographically close to your visitors. Search engines take the geolocation of a server into account as well as the server speed.
Use DNSstuff for comprehensive reports on your server.
Technologies
Get to know the technologies used for your website. Some codes might slow down your website. Ask your webmaster to take a look at this.
Analytics
Web analytics let you measure visitor activity on your website. You should have at least one analytics tool installed, but It can also be good to install a second in order to cross-check the data.
Popular Analytics Tools Include: Google Analytics, Quantcast™, AdobeAnalytics™, Piwik™, chartbeat™, Clicky™, ClickTale™, etc.
Doctype
The Doctype is used to instruct web browsers about the document type being used. For example, what version of HTML the page is written in.
Declaring a doctype helps web browsers to render content correctly.
Encoding
Specifying language/character encoding can prevent problems with the rendering of special characters.
missing translation: en.encoding_contentBranding
URL
f2er.info
Length: 4 character(s)
Keep your URLs short and clean and avoid long domain names when possible.
A descriptive URL is better recognized by search engines. A user should be able to look at the address bar and make an accurate guess about the content of the page before reaching it (e.g., http://www.mysite.com/en/products).
Keep in mind that URLs are also an important part of a comprehensive SEO strategy. Use clean URLs to make your site more "crawlable" by Google.
Resource: Search for a good domain name. If no good names are available, consider a second hand domain. To prevent brand theft, you might consider trademarking your domain name.
Favicon
You can see how your site's favicon appears in search results in the Google Preview above.
Make sure your favicon is consistent with your brand to help improve visibility.
Custom 404 Page
Your website does not have a custom 404 Error Page.
Your server responded with the HTTP status code: 404404 error pages are displayed when the page you are trying to open can't be found on the site's server for a variety of reasons.
It looks like f2er.info doesn't have a customized 404 error page. This makes your site less user friendly. Generic 404 error pages strand users on a page with no links or suggestions of what to do next.
Use a custom 404 page to reduce customer frustration and link to other pages on your site. Make sure it returns the 404 http status code.
