Notes 8 small image optimization techniquesIf you operate online stores and sites or large electricity providers, image optimization is that you must master. Not only from attracting potential customers, or increase image search traffic, but also to enhance the site load or speed, image optimization actor crucial role. But when it comes to image optimization, SEO many people in the traditional sense would say that image to add alt tags to compress such a broad-brush picture is clearly not enough. Today I share with you and our in-depth picture optimization must know eight knowledge. 1. structured data write a product image ALT our easy to use camera default picture ID as pictures are named, so the search engines, there may be no way to identify the contents of the picture, so we lose search Picture piece children bring traffic, which is very unfortunate, especially when you have tens of thousands of words the product. Usually we can formulate rules for structured High Quality Nike Air Force 1 Low Unisex All White Shoes data and technical personnel design process batch replace image alt attributes, without us manually. We should think about what visitors search habits? Which keyword searches? Best you can look at Google's keyword data statistics inside and see whether the omission. Basically, visitors are more inclined to search word + phrase combinations and changes in product lines, so structured rule came out alt tags, can be written as: alt = {word} {brand product series} - {Model} . For a description of the product images, it is not recommended to write too much redundant content, maintain data structured, so that high keyword identification, keyword rich information on it, do not do keyword accumulation. 2. The image shooting angle problem is basically shooting Product photos are not only took an angle, visitors will certainly not be satisfied with only a frontal view, multi-angle to show pictures in order to better attract visitors stay on your site more time, before they can go to stimulate their desire to buy, so naturally need to take the front, back, side, details of the object, and so on, this time how to write alt tag? The best way is to keep the structure of the alt tag, inherit the main format chart, do not go to these pictures a new wording, the correct wording is as follows, alt = {word} {brand product series} - {Type} - Positive alt = {word} {brand product line} - { Model} - Back alt = {word} {brand product series} - {Type} - side holding trunk word} {{brand product series} - {} same product model allows search engines to fully confirm the current picture series or the page is about the key words, so that these pictures are search image search engines to greatly increased risk. Alone must fall. 3. The question of the big picture if you want to provide the bigger picture allows users to look cool, this idea is very good, but be very careful not to recommend the big picture directly on the web and then use css picture down, although you looks image smaller, but the size of the image is there really, this will affect the loading speed. Instead, you can put a smaller picture first, and then provide a larger view function option, either click on the pop-up big picture or another new page shows are ok. Of course, some people would cut a large image stitching Zhang diagram do, which could let the picture quickly display, but after a picture into small map, the number of requests the server will increase, which will affect the page loading speed . So, if the volume is too large picture of it, it suggests a new server specifically configured for the picture. 4. to lose some weight to look at pictures on these data, most desktop or notebook users will not wait more than three seconds Site loading speed on a mobile device will not wait more than 5 seconds at Amazon to find out if their site is slow to load 1 second, they will lose $ 1.6 billion a year search engine website loading speed ranking algorithm included among the large number Nike Air Max 90 Premium of sites if your image is very bloated, which would seriously affect the site loading speed, if more than 10 seconds, that You wait and you say byebye to customers. Image files should be? Some theories say that the image size should be kept at 70kb or less, but this is sometimes very difficult, especially for the big Nike Air Presto Mens picture, it is almost impossible, unless you do not seek clarity. Personally, I would think, do not use Air Jordan 22 a standard to limit the size of each picture, the key is that we have not to perform, I have not seen this blog to really compress image, this is the key. 5. The use of image formats currently has three very popular image formats, they are JPEG, GIF, and PNG. Let's see what they are different, JPEG (or .jpg) is the most common image compression format, support the highest levels of compression. Typically, high demand for the display image is, JPEG format images showing was better than GIF and PNG have a distinct advantage. GIFs (.gif) image shows a lot less quality than JPEGs, usually used as a very simple image display, such as material or decorative pattern, gif can be used to animate. gif is not suitable for use as high display quality pictures. PNG picture is a better choice than gif because PNG image support more colors than GIFs. In addition, and as JPEG, PNG repeatedly saved will not affect the picture quality, but also for a small map, the Top Design Nike Air Force 1 Unisex Yellow White Shoes volume occupied by the small PNG, PNG perfect support transparent background, so the general logo or general decorative pattern will choose PHG format. Note that PNG-24 image volume to over 3 times larger than PNG-8 version of the same case, you have to be very careful to treat PNG, read them carefully. By contrast at the same volume (all 24kb) The pictures show the effect of different formats, tested 2015 Latest Nike Shoes can be seen, JPEG is a winner, in the same volume, GIFs and PNGs have to sacrifice image quality for the price. But then again, if the picture is very small (eg less than 5K), PNG is a better choice than GIF, PNG can still will not let the picture distortion at Genuine Nike Air Force 1 Unisex Black White Shoes very small case. When we select a picture format, as some of the tips for your reference, for the electricity supplier sites, demanding quality product images, JPEGs undoubtedly the first choice, they have a relatively high-quality image display and will not take up too much volume. Never use GIFs to as Big Picture. Otherwise the file size will be very large, there is no good way to compress it (a compression to distortion). GIFs can be animated or decorative inset. PNG can be used as an alternative JPEGs and GIFS, if you want to make PNG format product pictures, rather than try to use PNG-8 PNG-24. PNGs also adept at handling simple diagram and simply decorated a small volume, PNG will become more popular. Incidentally, most of the photo editing software can convert more than three types of image formats. 6. The most correct view thumbnails electricity supplier site has a thumbnail display, which allows visitors to quickly scan to as many commodity style without having to go to click on an extra page. Thumbnail great, but be careful, they may be the speed of your website killer. They usually appear in the shopping process among the key, if thus affecting the smooth shopping process, the amount then you may well lose a customer. About thumbnail, I personally have the following two suggestions: as compressed thumbnail size, a thumbnail picture is not too high in the pursuit of display quality, when the user clicks on to the next level detail page of time to give him a high-quality Pictures. Try not to set the alt tag as a thumbnail, usually we do not want search engines to index thumbnail and picture should be of high quality product detail page. 7. Use the Map If your site using JS to do a better picture effect to enhance the user experience, are you worried about whether the image is still included? Of course, it usually is not crawling spiders are not displayed in the source code inside the image file but Google has a lot of experience to this point, and by pictures maps submitted that one of the pictures address listed honestly, search engines can crawl. For image maps, I will not say more, because Google has many guidance documents to help you improve image search ranking, see here. 8. careful decorative image non-product categories such as background images, buttons, maps, diagrams can be counted as a decorative border, is used as an optimizer, you need to be careful to check the volume of these pictures is too large, it will affect the site loading speed. Here are some suggestions on how to compress Decorative Figure: if only some of the Border class, or simply the style of the picture, use PNG-8 or GIFs, you can create great looking pictures and only a few hundred bytes of volume. If possible, try to use css to create some special effects, rather than image. Not recommended for the site set the background image, if there must be, then, to ensure the greatest degree of clarity to the premise of the compression volume. You can also put them hollow or background remains transparent to compress the volume. Well, today I will share about image optimization here, we Have a better suggestion? Look forward to your message, we explore common progress. Source: Contributor, Author: Fimen, the original link.
