At the invitation of Baidu webmaster platform, I took the time to add some details to this article. Welcome to pay attention to it and discuss it. At this stage, due to the development of touch screen technology and mobile Internet, SEO is also faced with a variety of algorithmic changes, technological changes or further changes in marketing methods. These changes, for some technical details, are often unable to take into account. Next, it is necessary to upgrade China Website construction company Let's take a look at some of the current mainstream technical errors to the website SEO optimization The adverse effects.
1. No Mobile website Or your mobile site just does simple transcoding and browser adaptation, and your mobile search results will be very bad. This is particularly prominent in Baidu. It is said that Baidu has an online tool to test the scores of mobile sites. If your site is a mobile site of H5 and adapts, you may get a higher score. However, it is observed that the mobile site of H5 is still not ranked as well as the mobile site of H4, with high traffic, I believe there will be changes in the future (purely my own experience in SEO projects, and different views are welcome to discuss).
2. Infinite Endless Scroll In order to adapt to mobile phone or tablet browsing, your website uses a seemingly cool but very bad technology - unlimited scrolling. It should be noted here that search engines will neither learn to scroll the mouse nor read your so-called trigger code without restrictions. To put it bluntly, unlimited scrolling makes your website lose almost 99% of its content.
As explained here, infinite scrolling - it is a web interaction technology, especially an interaction often used by microblogging, social networking and other websites, and it is especially suitable for touch screens. Users are encouraged to pull down and look until they see that they don't want to look! In this way, the original paging browsing method is abandoned, so that users can no longer click the mouse. It looks perfect. In fact, there are three disadvantages of this technology SEO
1) This interaction is aimed at human behavior. At present, mainstream search engines have no official instructions to support such infinite scrolling technology. 2) The non pagination method leads to a decrease in the number of pages, which may affect your collection and ranking. 3) This kind of interaction is bound to make your server more stressed and load more slowly, and the search engine cannot guarantee that it will stay on this page for enough time.
Of course, this interaction still has many advantages, such as more browsing content, dwell time, and customization for touch screen.
3. Lazy Loading This technology can be used by many websites (jQuery seems to be the mainstream). The technology is well known for improving website speed and user experience. In fact, in the era of Internet explosion, it is really shameful to complain about the server being insufficient and the slow speed of the network. The delayed loading results in the search engine being unable to move the mouse like people, Search engines will only choose to see the content on your first page, and the rest is still blank. Unless your website does not consider SEO, you should honestly discard this technology that looks cool and sounds awesome - in fact, it is really going to be eliminated, 4G is coming, and you need to worry about network speed?
For example: <img src="loader.gif" data-src="img1.jpg" />
This code cannot effectively capture the delayed loading content and images, so it is not recommended to use this method. Of course, there are also technical indications that you can use<noscript>tags to display content instead of javascript It has not been tested yet, so whether it is useful remains to be verified.
Of course, some children's shoes will think that if they submit image content with sitemap, can they ensure that the image will be included? Here we can definitely give you a NO answer. The case is as follows:
After testing, it was found that none of these submitted pictures were included 2 years later (friendship test of foreign friends)
Of course, there are also instructions from Google that can solve this problem, which is the same principle as solving AJAX. You can see the help of Google developers, //developers.google.com/webmasters/ajax-crawling/
Is there a better way? Of course there are, for example <a href=' //www.idea-r.it/...?blogimage= <image-number>' onclick='... show(<image-number>); return false;'> This code means that if the search engine sees it, it will directly read the URL in the href. If the user sees the image content, it will kill two birds with one stone.
4. Parallax It can also be called using the difference between the foreground and background of the picture to create a very cool scene. This technology, I just want to say one word: you live in your own YY world, and you are dreaming that the user will also YY with you. The user only wants to solve his needs, not to YY with you. The above technology is mostly used on some brand websites. First, look at a few pictures to see what it looks like:
Yes, it's a cool feeling. Many pages are grouped into one page. We all know that in the world of SEO, more pages mean more keywords, rankings, and traffic. This is basically a positive correlation. Use pictures to speak more vividly:
This is a very vivid explanation of the direct impact of parallax. Of course, many people may say that different H tags are used to distinguish different pages, but I want to say that this is definitely not a very good solution. It can be said that your SEO can't do as well as others.
5. Hamburger Menus We often see this hamburger style menu on the mobile phone or tablet. When you click it, you will see the link in the navigation bar. Then you can click it again to see the content. But if this technology is used on the PC, it will be a disaster. If you have important content but do not show it to users at the first time, users need to click the mouse to see it, So what are you going to do with Nuoda's PC screen? The following is the menu we often see on the mobile terminal, see if you are familiar with it?
Although it is good on the mobile side, it does not mean that the hamburger style menu should be transferred to the PC side. Users prefer to find the navigation and content they want directly and accurately on the PC instead of showing them the hamburger menu.
The above are five technical mistakes that have a greater impact on SEO technology. In fact, it is risky to take the risk of adopting these technologies when the search engine technology has not been fully able to achieve more intelligence. If your website needs SEO traffic in particular, it is not recommended to use these technologies. I hope you can make good use of the technology and do a good job in SEO, I also hope Baidu can make more innovations in technology and support the development of SEO.
