The end of 2013 Baidu search results for all sites began to appear "thumbnail", causing widespread concern, people on the site picture optimization of the degree of attention began to gradually strengthen. But talking about the optimization of the site image, how do we do it? Perhaps many friends will say, because the search engine also recognizes the image of the technology is not immature, is simply to add a descriptive text description. What I want to say is that for the optimization of the site image, you will only "ALT"? Let's explore the following, the site image optimization can also be what operations.

Website Picture description

Search engines cannot directly read pictures, so it is necessary to have descriptive text for the pictures on the site. In general, we give the picture to add descriptive text commonly used have ALT, Title. Some people also like to use two. For search engines, Alt is a bit more important, and Titele allows the user to display the appropriate text when the mouse hovers over the picture. So how does alt explain how text should be added?

Some people think that the picture description text should use a word and into the keyword to describe, and some people think should be concise and accurate should not be too much redundant content. I personally prefer the latter. For example, we are a network company, in the website to introduce our company's set up the station package, will use the picture form to show to the customer, then I in these pictures "ALT" when it will write: Basic Web site Construction package, marketing-type website Construction package ... If your site is really introducing a product, then write the product name, model, etc. ALT attribute is an important part of search engine optimization, here we recommend "Alt" when the best keyword, you can enhance the theme of the page keyword, but do not stack keywords. At the same time, the picture added note text should also pay attention to the relevance of the text.

There is also a question about the name of the picture, but have to say that the site to upload pictures are manually named is a very cumbersome thing, the vast majority of sites are automatically named by some rule. In fact, we do not need to do so meticulous, I remember Zac in the SEO actual code inside is so said: Picture file name contains keywords on the picture itself in the picture results, as well as the page's relevance is a certain impact. This optimization is mainly expressed in English websites, Chinese websites use Chinese keywords to do image file names and keywords appear in the URL similar, the role is not, sometimes outweigh the gains.

About website Image originality

How far has the search engine identified the picture? Can you identify the originality of the picture? In fact, the search engine in this area has made fruitful achievements, such as the current Baidu map, we can be above the "map search" (Below is my example of the map search). How do search engines add "fingerprints" to these images?

According to my superficial understanding, the search engine for the image algorithm mainly has calculates the hash value, the Phash algorithm and the SIFT algorithm and so on. According to these algorithms, the target image is encoded to form a "fingerprint" to be stored. So in a way, the search engine for the image of the original identification or have a certain ability. But now the technology is not very mature, sometimes you search the map when there are a lot of inaccurate. See here, I believe a lot of friends are going to crash, the original article has been hard enough, now do you want to go to the pursuit of original pictures? This is more than the pursuit of original text more pit dad ah.

However, because the search engine for the image of the algorithm technology is limited. The image you search on the Internet can still be used, but if you can go through some processing is better, then what are the operating methods?

1, in the picture watermark, with the company name and Web site

2, change the original picture of the length of the size ratio, or directly intercept a part of the picture

3, if you have a little image processing technology base, you can properly splicing some pictures, so that it looks original

Picture format and size

What kind of picture format and picture size is more friendly to search engines? about the picture format of the problem, personal advice or PNG is better, and Baidu Webmaster platform inside the picture is PNG format (as shown below) hehe!

The advantages of the PNG format picture are obvious: small size, indexed color mode, more optimized network transport display, and support for transparent effects. In addition, the repeated preservation of PNG does not affect picture quality. PNG is a format that replaces traditional pictures and will become more mainstream later.

So what kind of picture size is more friendly to search engines? Here is a good reference data, Baidu search results thumbnail size is 121*75. This means that the aspect ratio is better in the range of 5:3. This is similar to the computer screen size, it seems that the search engine prefers the "widescreen" picture. Now, of course, it's just the current situation and how it's going to be unpredictable.

Advantages of internal chain construction in thumbnails

I think since Baidu search results have thumbnails, then we do the site within the chain, when recommending other content pages to visitors, if the use of thumbnails in the form of recommendations is not more conducive to user experience? for example, Webmaster home in the latest graphics and text recommendation is very good, picture links can be more extensive to attract visitors to the field of vision, The visual impact on visitors is even greater. Compared to text links, it's more appealing to visitors, especially when you have a good selection of pictures and visuals.

How much does it mean to optimize a picture search?

I believe many people think that the optimization of image search is not meaningful, indeed, and this is related to industry factors, most people think that the conversion rate of image search is extremely low. But what I'm trying to say is that if you can combine your industry with the right energy to do something, there may be some gains. In my own website construction industry, some customers may want to know about the website construction flow chart and so on some knowledge, will go to search this kind of picture, then we will use this to design a website construction flow chart to come out, will flow chart to do accurately, the appearance, may attract the user to click to view, In the picture to do with the company name and URL watermark, in a good picture source, it is possible to attract customers to browse your site, and then reach the order.

In addition, users may have to search for images for this purpose, for example, he already know your company, but want to more comprehensive understanding, to our Suzhou Tianma Network for example, customers may be doing the site before, want to know what our company is like, they will go to search "Suzhou Tianma Network Company" related to the picture, Look at the company's office environment, the size of the strength of the company, is not formal. By showing these images to potential customers, you can increase your chances of winning in competition with your competitors.

Write in the last: the website is the text is also the picture, also is the video. Simple article optimization has not been able to meet the search engine requirements for the site. Because the customer's demand for the site is no longer just text. Website optimization tends to diversify is inevitable. Word: To meet the needs of users to improve user experience!
