New things are everyone like, search engine crawler also like, and then there are SEO friends in the site optimization process have encountered such a problem, may be their own site every day to update the original, or even article seconds, but the home snapshot or even back to the file to n years ago. The author has seen many SEO forums on many such advisory issues, in general, some SEO friends answer all think: first, the site itself did not adhere to the update, the second is the Baidu database problems. The solution to this problem is not to let him continue to wait is a complaint snapshot, personally think this can not solve the problem of the front page snapshot backward.
I suggest here, home can not like the portal to save a large update can try to invoke random articles and products. Random articles and random products are generally the program to form a new functional module by randomly fetching the articles list and the random article serial number and product serial number in the Product list. This technology generally for SEO friends to recognize, especially in the station to optimize the time, in the article or product page randomly pull out a section of random articles and products, on the one hand to enhance the user experience, the user every time to see the results are not the same, on the other hand search engine crawler every time to have something Keep the article inside page and product update, increase the spider viscosity, improve the site page ranking.
I optimized the site dozens of, home Baidu Snapshot does not update the case is also very much, take the author of the most recent optimization of the site local wine network, the home page snapshot in the optimization before the snapshot can not keep up, even snapshots lag more than three days. The author preliminary analysis is because the home page did not maintain a good update, because the new product is less, the home page update amplitude is too small, the update amplitude of less than 10%. In order to solve the small update, we have a revision of the home page, the product and the original slide into the floor style, and the products are randomly appearing, save users and search engine crawler come every time is new, the following figure
Pre-revision Slide product display chart
After the revision of "floor-style" product display
Website after the revision, the effect is very good, the site snapshots updated every day, search engine crawler is also very frequent. The Daily collection amount is more than 3,000.
Therefore, it is very necessary to use random articles and random products in the case of limited amount of articles and product updates. In particular, corporate web products are generally not often updated, updated article is also two or three bottles a day, it is very necessary to call random articles and products, save the first page of a large update, so that the first snapshot every day.
