Free membership registrationIt is said that 53% of users will leave a mobile site if it takes more than 3 seconds to load. Websites that Spelldata has optimized for web performance tuning services to achieve a loading completion time of 1 second have seen their bounce rates drop to around 30%. Additionally, for all the sites we have been involved in speeding up or improving, access via smartphones exceeds 50%. If the conversion rate for smartphone access is lower than that for desktops, it may be due to speed delays. [Overview (Partial)] ■ Overview of global mobile site loading time survey ■ Overview of the relationship between loading time and bounce rate ■ Expectations for 5G, but the actual situation is uncertain ■ Still questioning the benefits of website speed optimization? *You can view the detailed content of the blog through the related links.

Free membership registrationTo understand what constitutes a "high-quality site with original and useful content," it is important for everyone to be aware of "information quality." Activities related to information quality in computer science conferences began over 10 years ago. Additionally, there is the question, "If the value of information is high when the content is surprising, does that mean that lies or dubious content are acceptable?" This is precisely the issue we are currently facing with web content.

Free membership registrationIn America, IT engineers, as well as other engineers and various professions, cannot enter their jobs without graduating from a specialized department at a university. I believe that the perception of criticism towards beginners' technical mistakes as "correctness harassment" is due to unique circumstances in Japan. When writing any technical article, one would have learned the conventions of technical writing by the time they graduate from an engineering department, and they would likely not make common mistakes typical of beginners. In America, there is a clear classification regarding engineers.

Free membership registrationYou may also have concerns in your daily work, such as "I don't really understand the web" or "I don't really understand IT." Currently, what is being promoted worldwide is programming education for elementary, middle, and high school students. In developed countries, IT education for university students has been advancing since the 1990s, and in Europe and the United States, new IT services have been easily understood and adopted by the white-collar workforce who graduated from university. However, in Japan, there are many business owners and middle managers who say "I don't really understand IT," and because they cannot understand it, it does not spread. As a result, the productivity of white-collar workers is significantly lower compared to the rest of the world. *You can view more details about the blog through the related links.

Free membership registrationInformation structuring refers to the process of coding information (content) on a web page in HTML with appropriate semantic markup, so that machines can correctly understand it. Even if you read a web page and think, "I can read it properly and understand the content," whether it is "readable" for machines is a different matter. If you prioritize the "appearance" for humans and convert the text into an image, machines will not be able to read it. If it is not machine-readable, the result will be a web page that is not human-findable. *You can view detailed content of the blog through the related links.

Free membership registrationAccording to Google's digital marketing evangelist, all websites can be categorized into five types. E-commerce sites aim to increase the number of sales of products or services, while sites focused on lead generation aim to increase the number of inquiry form submissions. There are differences in goals based on the type of website. Unfortunately, it would be great if all five goals could be achieved with a single website, but that is quite difficult. Instead of being greedy and wanting "this and that," let's choose one necessary type of website for the current company and specialize in creating it. By doing so, it will become easier for people to understand, and the skills of the web manager will improve, leading to the development of a better website. *You can view the detailed content of the blog through the related links.

Free membership registrationRegardless of the type of website, what is common is that it primarily provides information. It can also be said that "websites distribute text data composed of characters, image data composed of images, and video data composed of videos." When data is perceived by humans through sensory organs such as eyes and ears, it is interpreted by the human brain. As a result of this interpretation, when "value" is found in that "data" within a person's mind, and it takes the form of a useful "notification," it becomes "information." [Overview (Part)] ■ What is information - Not all "data" becomes "information." - A "filter" that is acquired and strengthened through learning. *Detailed content of the blog can be viewed through related links.

Free membership registrationIn this blog, we break down the topic of "how to determine whether 'information' is valuable to oneself" into the thought processes of impression, recognition, evaluation, and influence. There are various indicators that shape impressions, such as whether something is trustworthy or not, stylish or uncool, wonderful or tacky, but many of these are dominated by "appearance." Therefore, in websites, the design in the narrow sense (visual design) that influences the impression when first seen is emphasized for this reason. 【Overview】 ■ From "data" to "information" - Impression - Recognition - Evaluation - Influence *For more details about the blog, you can view it through the related links.

Free membership registrationWith the revision of the Civil Code's obligations law, there will be a significant impact on websites and internet services. The term "quality" has been incorporated into the provisions of the Civil Code, meaning that not only the realization of specifications but also the quality as a non-functional requirement is now automatically included within the scope of contractual performance responsibility. Whether the responsibility regarding quality due to the Civil Code revision is seen as a "burden" or an "opportunity" will greatly change the business landscape. Considering the current poor delivery quality of Japanese websites and the reliance on the efforts of line providers and mobile companies for display speed, taking proactive measures now to differentiate business based on high quality will create a significant difference in future web production orders. *For more details on the blog, please refer to the related links.

Free membership registrationGoogle's emphasis on display speed in determining search rankings can be understood by considering where the "starting and ending points of the experience" are. The display of search results is not the endpoint of the search action; rather, the search action continues until a link is clicked from the list of search results and the actual web page data is displayed. If you are delivering high-value content or providing sufficient information about products and services, yet your search ranking is not improving or is declining, it is likely that your display speed is slow. If you suspect that your display speed may be slow, I highly recommend measuring it at least once. 【Overview】 ■ "The field trip is not over until you get home." ■ The reason Google prioritizes display speed in determining search rankings. ■ Would you like to measure your display speed? *You can view the detailed content of the blog through the related links.

Isn't it strange that when you search for "PageSpeed Insights" in English, hardly any blogs from people using it for business appear? In fact, webmasters, infrastructure engineers, and front-end engineers at overseas companies do not use PageSpeed Insights.

Free membership registrationInformation overload will continue to increase in the future, and people's free time will become scarcer and more fragmented. However, the importance of acquiring information will only grow. The advantage of paper newspapers is that they present a variety of information, regardless of one's interests. Yet, in modern society, the environment is so dense, busy, and diverse that it does not allow for such leisure. Readers quickly skim through headlines and summaries, picking and reading articles that interest them one after another. This is likely the style of readers who consume articles on their smartphones today. [Summary (partial)] - There are no people reading newspapers on the train now. - A time of transformation in revenue models. - Western newspapers focusing on speeding up their websites. - Relying on retargeting ads leads to self-destruction. *For more details about the blog, please refer to the related links.

Free membership registrationDelivery quality refers to the display speed and availability (ease of connection) of a web page. If the display speed is slow, the customer experience deteriorates, resulting in users becoming frustrated and leaving the site. Moreover, it is not necessarily the case that the web designer and the web analyst are the same person. If analyzing a website created by someone else, it is essential to check whether the site's design, page content, display speed, and availability are adequate.

Free membership registrationIn today's world, it has become commonplace to obtain various things immediately without waiting, such as shopping, restaurant and hotel reservations, and priority passes for attractions. The immediate satisfaction we can achieve is referred to in English as "instant gratification," and we have come to expect things to be available instantly, to the point where not being able to obtain something right away has become a source of stress. Moreover, when we build or update our own websites, we tend to focus on design, but in reality, as users looking at other websites, we do not seek a design that goes beyond readability. Websites that cannot meet users' demand for instant gratification—those that are slow to load, difficult to navigate, or hard to read—will likely struggle to survive in the competitive market moving forward.

Free membership registrationThis blog discusses the methods and countermeasures for phishing scams targeting insurance companies using Office 365. From April 15 to 30, 2020, PowerDMARC's security analysts discovered a new wave of phishing emails targeting major insurance companies in the Middle East. When our Security Operations Center tracked the links in these emails, it was found to be a phishing URL aimed at Microsoft Office 365 users. The solution is to adopt an authentication mechanism that checks all emails sent from your own domain and blocks only those sent without permission. As a leading provider of email security solutions, PowerDMARC is committed to raising awareness of the importance of protecting an organization's domain. *For more details, please refer to the related links. *For more information, please check the PDF materials or feel free to contact us.

Free membership registrationThe father of information technology stated, "The value of information is the magnitude of surprise." The more familiar the recipient is with the content of the information, the less valuable that information becomes. Conversely, the less the recipient knows about the content, the more valuable the information is. In other words, the value of information changes relatively based on how well the recipient understands the subject matter. This is defined as the amount of information. Based on probability theory, the way to quantify the value of information has been established. The greater the surprise from information that the reader does not know, the higher the value of that information. 【Levels of Communication Problems】 ■Level A: Technical Issues How accurately can symbols be transmitted in communication? ■Level B: Semantic Issues How accurately can the transmitted symbols convey the intended meaning? ■Level C: Effectiveness Issues How effectively does the received intention influence the desired action? *For more details, please refer to the PDF document or feel free to contact us.

CDN ensures the security of local government websites connected to the internet through WAF, DDoS defense mechanisms, BOT management, firewalls, and encryption via TLS, while also playing a role in making sure that the municipal site does not go down during disasters for the safety of residents. 【How can a CDN protect a website?】 ■ High Load Measures - Significantly reduces the load on the municipal web server - Can withstand hundreds of thousands of simultaneous accesses ■ Blocking Submissions to Forms - Blocks submissions from paths not typically used by residents - Prevents submissions of bomb threats or kidnapping threats ■ DDoS Defense - Effectively defends against DDoS attacks, ensuring uninterrupted service for residents - DDoS defense is included in the pricing *For more details, please refer to the PDF materials or feel free to contact us.

Free membership registrationIn accordance with the "Quality Assurance of Sales" stipulated in the revised Civil Code on Obligations scheduled to take effect on April 1, 2020, we clarify the SLA of Cloudflare's services. The Free and Pro plans do not have an SLA, while the Business and Enterprise plans do have an SLA. The Business plan is a self-service plan, so support is available via email, chat, or the Cloudflare community forum. Additionally, the Business plan includes a guarantee regarding availability, but there is no guarantee regarding performance. The Enterprise plan assigns a dedicated customer support manager and SE from Cloudflare. The significant difference is that it includes a performance guarantee, ensuring that delivery will always be faster than from the origin. Furthermore, during high load times, the Business plan may deliver from overseas data centers, whereas the Enterprise plan will scale out using domestic servers. *For more details, please refer to the related link page or feel free to contact us.
