不銹鋼無縫管對比於有縫管，更能承受更多的壓力；不銹鋼管不易生銹的特性也廣泛地運用在各種食品級、醫療級配管。但不銹鋼相較於鋁、銅等材質，是相對難加工及磨損刀片甚劇的，可以說是耗時費材。尤其是外徑大內徑大的尺寸，不少業界同仁更至視為畏途。

例如之前有一筆外徑內徑的美標訂單，每米長重量公斤的實心棒材，便有公斤多是廢料，實心空心比例高達.倍。然而，倘若經由敝公司的客製化無縫管訂製，一來一體成形，無須多花時間鑽孔，是謂省時；二來重達公斤的米實心棒，倘若假設每公斤元，那米長就是元的成本。相較之下，訂製米空心管只需要將近公斤，是謂省料，而我們的價格總單價也絕對遠低於元；三來現成的空心管材只要經由剪裁、車牙、倒角等，就可以廣泛應用於螺母、汽車零件、快速接頭、食品級管材等成品，可謂好加工。在節省了成本，加工時間的雙重優勢下，不但增加了獲利空間，更有利於台灣的企業搶單。對於汽車工業、造船工業、金屬加工、工程機械業都可以互利進而創造雙贏局面。

Robots.txt Test
This website is using a robots.txt file.
Check if your website is using a robots.txt file. When search engine robots crawl a website, they typically first access a site's robots.txt file. Robots.txt tells Googlebot and other crawlers what is and is not allowed to be crawled on your site.

Image Alt Test
Your webpage has 10 'img' tags and 8 of them are missing the required 'alt' attribute.

Image Alt Test

How to pass this test?

In order to pass this test you must add an alt attribute to every <img> tag used into your webpage.
An image with an alternate text specified is inserted using the following HTML line: 
<img src="image.png" alt="text_to_describe_your_image">
Remember that the point of alt text is to provide the same functional information that a visual user would see. Search engines, users who disabled images in their browsers and other agents who are unable to see the images on your webpage can read the alt attributes assigned to the image since they cannot view it.

Learn more about optimizing images for SEO.
Check if images on your webpage are using alt attributes. If an image cannot be displayed (e.g., due to broken image source, slow internet connection, etc), the alt attribute provides alternative information. Using relevant keywords and text in the alt attribute can help both users and search engines better interpret the subject of an image.

- If you are using JS plugins or other third party code, you must carefully read the documentation;
- Syntax errors (a typo or missing character) are easy to fix;
Check your page for JavaScript errors. These errors may prevent users from properly viewing your pages and impact their user experience. Sites with poor user experience tend to rank worse in search engine results.

Get detailed and accurate loading speed reports for your websites and see how your pages are being loaded over time.

Check your website's loading speed. Page speed is an important factors in search engine rankings and overall site success. Pages that take longer than 5 seconds to load can lose up to 50% of users. Faster webpages result in higher traffic, better conversions and increased sales over slower loading pages.
Page Objects
Your page has more than 20 http requests, which can slow down page loading. You can try reducing http requests through various methods such as using text instead of images, using css sprites, using data URIs instead of images, or combining several external files together into one.
Total Objects: 49
  • 6 HTML Pages
  • 11 CSS Files
  • 17 JS Files
  • 15 Images
  • 0 Flash Files
Check if all the objects requested by this webpage can be retrieved. If they are not retrievable, your page may display incorrectly, leading to a bad user experience and lower search engine rankings.
Image Caching Test
Your site is not using expires headers for all of your images. An expires tag can help speed up the serving of your webpages for users that regularly visit your site and see the same images. Learn more about how to add expires headers to your images.

Image Caching Test

How to pass this test?

In order to reduce the number of HTTP requests, you can use the HTTP Expires header to set an expiration time for your images or any other content type. You can add the following lines into your .htaccess file: 
<IfModule mod_expires.c>
    ExpiresActive on
 
    ExpiresByType image/jpg "access plus 1 month"
    ExpiresByType image/jpeg "access plus 1 month"
    ExpiresByType image/gif "access plus 1 month"
    ExpiresByType image/png "access plus 1 month"
</IfModule>
Checks if your page is using an image expires tag, which specifies a future expiration date for your images. Users browsers will see this tag and cache the image in their browser until the specified date (so that it does not keep re-fetching the unchanged image from your server). This speeds up your site the next time returning visitors arrive at your site and require the same image.

URL Canonicalization Test
http://www.zssco.com.tw/index.html and http://zssco.com.tw/index.html resolve to the same URL.
Test your site for potential URL canonicalization issues. Canonicalization describes how a site can use slightly different URLs for the same page (e.g., if http://www.example.com and http://example.com displays the same page but do not resolve to the same URL). If this happens, search engines may be unsure about which URL is the correct one to index. Learn more about canonicalization issues.
HTTPS Test
Your website is not using https, a secure communication protocol. Even for sites that do not collect senstive customer information, search engines suggest that switching to https is an increasingly good idea and may help improve rankings. Note: if your site relies primarily on adsense income, be aware that using https may be detrimental to ad earnings.

HTTPS Test

How to pass this test?

If your website needs a secured authentication or an encrypted transfer of data, you need to install an SSL certificate in order to provide a secure connection over HTTPS protocol. HERE is a "step by step" guide to purchase and install an SSL certificate.
Check if your website is using HTTPS, a secure protocol for sending/receiving data over the Internet. Using HTTPS indicates that an additional encryption/authentication layer was added between client and server. HTTPS should be used by any site that collects sensitive customer data such as credit card information. Even for sites that do not collect such data, switching to https helps users by improving privacy and overall security. Google is increasingly using https as a positive ranking factor.
Plaintext Emails Test
We found 1 email addresses in your page code. We advise you to protect email links in a way that hides them from the spam harvesters.

Plaintext Emails Test

How to pass this test?

In order to pass this test you must make your email addresses invisible to email spiders. Note that the best option is to replace your entire contact mechanism with a contact form and using the POST method while submitting the form. Other solutions are listed below:
  • replace the at (@) and dot (.) characters
  • replace text with images
  • use email obfuscators
  • hide email addresses using JavaScript or CSS trick
Check your webpage for plaintext email addresses. Any e-mail address posted in public is likely to be automatically collected by computer software used by bulk emailers (a process known as e-mail address harvesting). A spam harvester can read through the pages in your site and extract plaintext email addresses which are then added to bulk marketing databases (resulting in more inbox spam). There are several methods for email obfuscation.

Microdata Schema Test
Your webpage doesn't take the advantages of HTML Microdata specifications in order to markup structured data. View Google's guide for getting started with microdata.

Microdata Schema Test

How to pass this test?

HTML5 Microdata is an easy way to add semantic markup to your web pages. Search engines rely on this markup to improve the display of search results, making it easier for people to find the right web pages.
Here is a simple example of how to use HTML5 microdata in your contact web page: 
<div itemscope itemtype="http://schema.org/Person">
   <span itemprop="name">Joe Doe</span>
   <span itemprop="company">The Example Company</span>
   <span itemprop="tel">604-555-1234</span>
   <a itemprop="email" href="mailto:joe.doe@example.com">joe.doe@example.com</a>
</div>
Check if your website uses HTML Microdata specifications (or structured data markup). Search engines use microdata to better understand the content of your site and create rich snippets in search results (which helps increase click-through rate to your site).
Noindex Checker
Your webpage does not use the noindex meta tag. This means that your webpage will be read and indexed by search engines.
Check if your webpage is using the robots meta tag or the X-Robots-Tag HTTP header to instruct search engines not to show your site in search results pages.
Canonical Tag Checker
Your page does not use the canonical link tag.
Check if your webpage is using the canonical link tag. The canonical link tag is used to nominate a primary page when you have several pages with duplicate or very similar content.
Nofollow Checker
Your webpage does not use the nofollow meta tag. This means that search engins will crawl all links from your webpage.
Check if your webpage is using the robots meta tag or the X-Robots-Tag HTTP header to instruct search engines not to follow the links on your page. Outgoing links marked with this tag will tell search engines not to follow or crawl that particular link. Google recommends that nofollow tags are used for paid advertisements on your site and links to pages that have not been vetted as trusted sites (e.g., links posted by users of your site).
Disallow Directive Checker
Your robots.txt file does not use the disallow directive. This means that the whole website can be crawled by search engines.
Check if your robots.txt file is instructing search engine crawlers to avoid parts of your website. The disallow directive is used in robots.txt to tell search engines not to crawl and index a file, page, or directory.
SPF records checker
Congratulations! Your DNS server is using an SPF record. This SPF record is listed below:
v=spf1 include:hibox.hinet.net ~all
Check if your DNS records contains an SPF record. SPF (Sender Policy Framework) records allow email systems to verify if a given mail server has been authorized to send mail on behalf of your domain. Creating an SPF record increases email delivery rates by reducing the likelihood of your email being marked as spam.
