Grabbing, when is it? How often to refresh and when to crawl the site?

Spider visits are regular. The more you update, the more it comes. There's a lot of information on the internet. You can search for more.

Yesterday's one was too rushed, and today I added some. Generally speaking, if you update every day, the spider will come every day. If it is updated once a week, the cycle of the spider is one week.

Push back and update once a month, and the spider comes once a month. Of course, it's not just a daily update. Some ** are updated every day, but as long as they are not updated for a period of time in between, the spider may not come.

So the crawling depends on the spider visiting. Hope it helps.

How to catch the pattern of recent updates? After changing the algorithm n times,The update law has also been changing,This is the update law summarized by netizens after the recent algorithm change,For every webmaster,Accurate grasp of the update law can have a pre-estimate in front of many things。 It's also a lot more convenient.

The daily update pattern is as follows.

The first time: 4-5 o'clock in the morning, at this time your ** must not be opened, otherwise your inclusion today will be regarded as 0 increase, the content added between 20-24 o'clock the day before will be included this time, if there is no new content, your snapshot will stop yesterday or earlier;

The second time: 8-9 o'clock in the morning, this update will release the new content crawled in the early morning, and the new content will be crawled again;

The third time: around 13 o'clock at noon, this update is to adjust the first two errors, if the inclusion is wrong or disordered, this time it will be adjusted to normal;

The above is the default five update periods per day, in fact, there are more than these five updates, but these five time periods are still the most important of the day.

In addition, let's talk about the update every Monday to Sunday, which has been said before, so I won't go into detail here, but I will probably say it: it is updated every day, but there are a few more important days that must be grasped:

Wednesday update, but Wednesday's update is more complicated and messy, don't be annoyed or happy about today's update, because tomorrow will be adjusted normally;

A small update on Thursday to adjust the mess on Wednesday in preparation for Friday's big update;

Friday is the most important, rankings, weights, backlinks, indexing, etc., will have a significant impact and change on this day, which will affect the ranking and weight between this Friday and next Wednesday.

Sunday's big update, yes, that's right, Sunday has also become a big update of French red wines from the previous non-update, if you don't update on Saturday and Sunday**, then sadly, your ranking will suffer from Monday to Wednesday.

Simply next week.

One, two, six, these days will include new content, external links and small update rankings, the reason why I say small, because, if you don't do a good job, or the opponent surpasses you, there will be a slight decline, at the same time, these days** content updates and external links increase is very important, these days of work are for.

Great preparations were made on the third, fourth, fifth, and fifth days.

If you create a new keyword, such as creating a long-tail keyword, but it must be unique, in this way, the spider may crawl your UPL on the same day, and then temporarily store it in the database, which is the fastest, the slowest basically crawls once a month, if you send advertorials every day, or thank you for the link, backlink, this will improve your **weight, the number of times the weight is high will also be diligent, or update your **keyword, he will come very diligently, my station basically climbs several times a day Satisfied with the points, Generally, there will be updates every Thursday.,Priority traversal static**,Because there can be an endless loop in the dynamic**,So that the spider can't get out.,But the process of ordinary spider search will first detect the security.** If you find these devastating measures, you will avoid them. I think it's worth considering that in the process of establishing a dynamic **, we must be careful about our own order**, so as not to form **gaps, and in the end no spider dares to enter.

I don't know what refresh you mean when you talk about refresh problems. Grabbing **, it should be 24 hours a day, but the specific time period to go to your **, it depends on the specific situation, but the time when he arrives at some ** is roughly fixed.

If you're talking about SEO, the search engine update cycle is about 3 months, crawling, the higher the frequency of your ** update, the more opportunities for crawling, but the content requirements are best original.

From time to time, send spiders out to crawl ** relevant information to see if there is an update, whether it is important or not.

There are no strict rules for irregularities.

You can look at your log. You can take a look at the crawling time pattern of spiders, and you can update it before crawling.

Look at your update speed, be regular, update it often at which point it will come often.

I don't know, none of the ones I posted today are included, which means that the spider didn't come.

It's usually early in the morning, but if your ** is good, then the spider will always stay on your **.

It has a certain relationship with the length of the release time, but it is also related to the weight (the trust of the search engine in the search engine), some of the high weight, the update of the original article in a timely manner**Because the spider often visits, it can often achieve the effect of "second receipt" (that is, the information will be included immediately after uploading**).

As long as friends insist on uploading original articles regularly every day, and insist on building external links on a daily basis, I believe that it is not a dream for friends to be "received in seconds".

Don't repeat the information, it's better to collect points than long times.

You can, the time to grab is so fast, it depends on your question.

Everyone is different, some are received in seconds, some are included on the same day, some are included every other day, and some are included in several days, which is related to the quality of the inclusion, but it is not necessarily original will be included, and there are also times when spiders come to scratch, and there are also inclusions that cannot be specified Sometimes it is really only when it is included that you will understand that there is no need to study in depth how long to include the problem of no results and it is not very meaningful.

Not necessarily, maybe it's a good deal.

It's nice to have a conversation.

Generally, it is updated every Wednesday or Thursday: if there is no new content for a long time, then the update time will gradually increase, and if there is new original content every day, then the update time in the snapshot will gradually shorten to the frequency of each day. In fact, the problem of snapshot inclusion and updating is a test for **SEO specialists.

Generally, spiders will crawl your **content.,And then see if it's valuable.,It's not that the more updates or the content is original, it will be included.。

It's hard to say, there is no absolute, you can only insist, slowly weight the weight to cultivate the weight, and raise it for a few months.

In short, all that can be done is to wait and add updates. Ah, it's not easy to say that I love you!!
