Three main points of seo optimizationIn the eyes of industry experts, 谷歌seo Indeed, it has great development potential, which makes many investors more interested. https://www.365seo.cc/

　　

　　Seo is just a part of marketing, not unfathomable and far behind. Like using word office software, it is an easy skill to learn; What’s more, in today’s internet age, foreign trade enterprises have to learn more than seo. As far as seo is concerned, the most important thing for enterprises should be:

　　

　　Familiar with the rules.

　　

　　Unfamiliar with the rules of the game, it is easy to foul, and the foul will be punished; Being punished on the search engine is not a good thing. It may take six months to several years to recover, and the lost business opportunity cost is huge.

　　

　　Most foreign trade companies have a wide range of products. For example, a trading company with more than 200 landscape oil paintings uploaded them to the website, one on each page, and the title of each page was expressed in the same words. This leads to duplication, and search engines are likely to judge this behavior as cheating, although it is not intentional; What’s more, the content introduction is repeated, so it’s too late to regret. This is just a very simple detail. In search engine rules, there are many such rules, which are what foreign trade practitioners should learn and can learn.

　　

　　Second, effective websites.

　　

　　At present, the websites of most foreign trade enterprises are invalid, which means that they have no marketing function. If a website doesn’t have a good conversion channel, then the invested advertising can’t be sold on the website. In fact, there is little difference between such a website and not. If the product is not good, it is useless to do marketing alone; By the same token, websites can’t work, seo can’t be done well, and all other promotion and marketing are based on a good website.

　　

　　Third, good content.

　　

　　Seo or marketing, good content is the key. Search engines only include content. Without content, there is no cooking without rice and no roots. The forms of content are diverse, and words, videos and pictures can all be used to express the content. Only enterprises can provide complete product content. Who knows their products better than enterprises? It is impossible for technicians who undertake outsourcing to make websites to understand the content of products. Outsourcing technology is only an external cause, and good content is the internal cause.

　　

　　Judge the usefulness of keywords. Combining the three points mentioned above, what preparations should enterprises make?

　　

　　First of all, we should accept the concept that “the Internet era has indeed arrived” and realize that customers are using the Internet to search for information (except for a few industries). Secondly, we should have the concept of learning, practice while learning, and optimize Hebei website to improve the technical quality of foreign traders, so as to arm ourselves. There are more and more ways to find customers in foreign trade, which used to be exhibitions, b2b platforms, emails and other traditional ways, but now it is search engines, Google ads, social networks …

　　

　　There is a proverb abroad: “If I knew I would die there in my life, I would never go there.” Therefore, to do seo, you should first “know yourself and know yourself, and fight every battle.”

　　

　　In fact, many people don’t understand the steps of how to do seo well, but they know a little seo but have a little knowledge. The website they created is totally different. Use Google to search for led.

　　

　　Keywords such as supplier, there are a lot of led phrases in the article, and the bottom navigation, title and description are all LEDs. In fact, it’s all useless. seo serves foreign trade business, and so on, it can be said that it is a waste of time.

　　Generally do sem or seo will use google.Since then, more and more people have found that 谷歌优化排名 The value of, thus affecting the choice of many people. https://www.365seo.cc/

　　

　　Analytics to mine some data, mainly because ga provides a large number of data dimension subdivision and user-defined filtering conditions, which can easily obtain all kinds of desired data. [Google optimization” target=_blank>

　　

　　However, it is precisely because there are too many subdivided data, so when analyzing, we must not follow the superficial data values too much, but look at the meaning behind the data. Generally speaking, this kind of data is carried out by horizontal or vertical comparison of different data dimensions.

　　

　　We can easily catch the landing page and keywords of the website from ga, and make corresponding classification and trend statistics. After that, we can find that in a certain period of time, the landing page of the website has changed, and the keywords searched by the website have changed and started to increase.

　　

　　For example:

　　

　　For example, last month, we had 1,000 keywords and 500 landing pages and got 10,000 PVs. This month, we had 1,500 keywords and 600 landing pages and got 15,000 PVs. Obviously, the overall ranking of our website has improved, with 100 landing pages and 500 keywords and 5,000 PVs.

　　

　　At this time, we should be glad that the promotion or seo we have done has played a role, but is this really the case? At this time,

　　

　　We are going to check the keywords we have analyzed and the data on the landing page, and we are going to compare the changes in the past two months. You will find that there are several possibilities:

　　

　　1. The number of categories of keywords remains unchanged, but the number of one category has suddenly increased.

　　

　　2. The original classification number of keywords remains unchanged, and some new classified words have been added.

　　

　　3. The number of categories of keywords decreased in the previous period, and many new categories were added in this period.

　　

　　4. The landing pages have increased a lot, but the words brought by the original number and classification of landing pages have not changed much.

　　

　　5. A lot of landing pages have been added, but some of the original landing pages are missing or down.

　　

　　6. Wait, you can also find many factors.

　　

　　When you see these data and think back to our promotion strategy, you will find whether the results are consistent with your expectations. If not, it means that there is something wrong with our promotion strategy, such as less external links, less advertising, and what is wrong with links, right? We need to change them immediately!

　　

　　Wait, if you think so, you are cheated by the comparison of the two data.

　　

　　We need to look at the market, the base of keywords, and the trend of user search. Is it caused by the decline of the search base of this kind of products, the sudden popularity of this kind of search, how long is the popular trend of this kind of words, whether it is long-term or short-term, and so on.

　　

　　When you compare the third dimension, you will have a new idea about your promotion strategy, and you have to adjust it. If you want to change it, you have to wait and see if there is a fourth dimension, such as whether it meets the company’s long-term goals or whether it conflicts with the plans of the marketing department or the purchasing department.

　　

　　In short, when you compare N dimensions, what we need to do is a strategy and planning based on the whole.

　　

　　The above is “using google skillfully”

　　

　　Analytics to do seo optimization “all the content, only for webmaster friends interactive exchange learning, seo optimization is a process that needs to be adhered to, I hope everyone can make progress together.

　　In modern industrial automation, precision measurement, and numerous technological fields, sensors play a pivotal role as the core components for information acquisition. Among them, inductive sensors and capacitive sensors are two commonly used sensor types, each possessing unique advantages and applicable scenarios. This article conducts an in-depth comparison of inductive sensors and capacitive sensors from multiple dimensions, including working principles, performance characteristics, and application fields, aiming to provide valuable references for research and applications in related fields.from Ultrasonic Sensor From the reference value, it can also bring a lot of inspiration to other industries. https://www.hfyakexi.com/

　　

　　I. Working Principles

　　

　　Inductive sensors operate based on the principle of electromagnetic induction. They utilize changes in the self-inductance or mutual inductance coefficients of coils caused by measured physical quantities (such as displacement, pressure, flow rate, and vibration) to convert these non-electrical quantities into changes in voltage or current for output. When the current in the coil changes, it generates a changing magnetic field around it, and this changing magnetic field produces an induced electromotive force in nearby conductors. Inductive sensors leverage this mechanism to convert the measured non-electrical quantities into changes in inductance, which are then converted into electrical signals by a measurement circuit for output.

　　

　　Capacitive sensors use capacitors as sensing elements to detect changes in measured physical or mechanical quantities by measuring changes in the capacitance value of the capacitor. When the distance between two conductors or the medium changes, the capacitance of the capacitor changes accordingly. Capacitive sensors monitor this change in capacitance to detect parameters such as object position, displacement, and pressure.

　　

　　II. Performance Characteristics

　　

　　1.Measurement Range: Inductive sensors have a relatively large measurement range, typically reaching several meters or even tens of meters. In contrast, the measurement range of capacitive sensors is relatively small, generally ranging from a few millimeters to a few tens of millimeters.

　　3.Anti-interference Ability: Inductive sensors have strong inhibition against electromagnetic and radio frequency interference, demonstrating robust anti-interference capabilities. In contrast, capacitive sensors are susceptible to these interferences, exhibiting weaker anti-interference abilities.

　　

　　4.Measurement Accuracy: Inductive sensors offer high measurement accuracy, reaching micrometer or even nanometer levels. In contrast, the measurement accuracy of capacitive sensors is relatively lower, typically at the millimeter level.

　　

　　5.Response Speed: Inductive sensors have fast response speeds, reaching microsecond or even nanosecond levels. In contrast, the response speed of capacitive sensors is slower, generally in the millisecond range.

　　

　　III. Application Fields

　　

　　Inductive sensors, due to their no-moving-contact design, high reliability, long lifespan, high sensitivity, good linearity, and other characteristics, are widely used in industries such as textiles, chemical fibers, machine tools, machinery, and metallurgy for parameters measurement and control, including chain wheel tooth speed detection, chain conveyor speed and distance detection, displacement, vibration, strain, and more.

　　

　　Capacitive sensors, with their simple structure, high temperature resistance, radiation resistance, high resolution, and good dynamic response characteristics, are widely applied in fields such as healthcare, environmental monitoring, and food processing for parameters measurement, including pressure, displacement, humidity, liquid level, and more.

　　

　　IV. Conclusion

　　

　　Inductive sensors and capacitive sensors exhibit significant differences in working principles, performance characteristics, and application fields. Inductive sensors, based on the principle of electromagnetic induction, offer a large measurement range, high sensitivity, strong anti-interference ability, high measurement accuracy, and fast response speeds, making them suitable for precision measurement and control in fields such as industrial automation, robotics, and aerospace. In contrast, capacitive sensors, based on the principle of capacitance change, feature a simple structure, high temperature resistance, radiation resistance, and high resolution, and are widely used in parameter measurement in fields such as healthcare, environmental monitoring, and food processing.

　　

　　When selecting sensors, it is essential to choose the appropriate sensor type based on specific application requirements and environmental conditions. By deeply understanding the differences and characteristics of inductive sensors and capacitive sensors, we can provide more robust support for research and applications in related fields. With continuous technological advancements and expanding application fields, inductive sensors and capacitive sensors will continue to play important roles in industrial automation and precision measurement, contributing to the development of these industries.
