SEO process problems are not so easy to find and solve

My station has done 5 months of SEO, Baidu is ranked the first page. The most difficult thing for a friend who is engaged in SEO (Search engine optimization) is when they encounter setbacks and problems. Focus on those that are not penalized by search engines. Most of the time, even if you do everything right, you can get into this situation. This can be caused by a number of reasons, and here are some examples:

　　

Search engines (e.g., Google) have changed more than you expected, such as how Google recently crawled the JavaScript on the site. The Web development team has modified their code, which may not help SEO, and this often happens. The Web development team made some mistakes, for example, by copying pages containing "NOINDEX tag" from a development server to a product server.

Protect yourself.

Before the problem happens, one thing is important. is to make sure that you have saved the site changes and changes in the detailed log, not only about the SEO changes and changes. This log should include all major changes, such as domain name changes, navigation bar changes, or a new CMS system, and so on, but you should also record some other changes, including:

Changes to the Web Site Directory Menu implementation method

New analytics statistics are placed in the Web site

Web ads are in a new way

I chose the top 3 because most people may not think they will affect the effect of SEO, but the reality is that if done wrong, they can also affect the SEO effect. That's why your SEO log file (log) should be complete and exhaustive. The last step in setting up your own SEO log is to look at some authoritative SEO blogs and see what major search engine statements (announcements) or articles are on top of it, such as whether Google announced its algorithm changes or not, and whether they have recently changed their policy on nofollow? Are there a lot of people complaining that their search results have changed a lot (mostly bad)? You need to pay attention.

The first step in the diagnostics is to see when the site's traffic starts to drop. If the site is catastrophic sudden flow of traffic suddenly fall, then in the site statistics software can be easily seen. If the descent occurs slowly over a period of time, it is more difficult to discern, because sometimes the flow may be normal by the day/week trend. In any case, you should be sure when the downward trend begins.

Next, check to see if this downward trend is for the whole station or just a column. Also see if the drop in traffic is for all search engines or just for a search engine. Then, you want to confirm whether the problem is a search engine manual punishment. Finally, to SEO Blog and forum Check whether this time the search engine algorithm has no big changes. Once you find out what, the next step is to check your SEO log and see where the bottom problem occurs. But it's important that the site changes that were made after the drop in traffic or 6 months ago should not be the cause of the problem. The most likely time period should be a range of 5 days to 3 months in the downward trend, and of course the time range is not absolute.

Next, you need to start looking for the real cause of the problem. The basic process is to first check the occurrence of the phenomenon and the changes in the log is related to each other. In addition, the downward trend can also occur within 3 months after the SEO action to carry out step-by-step verification. For example: whether or not to change the column directory structure? Check the site's link search engine can still crawl? Are you using the new site statistics code? Of course, you have to confirm that the code used for site statistics and analysis has been correctly added to the site.

Once you find something special, revise it to see if it solves your problem. Generally speaking, the time delay after the change is changed, and the time delay that the change that causes the traffic drop in your log is the same as that of the traffic start to decline.

There will always be big and small problems in the SEO process. Unfortunately, the problem is not so easily found and solved. So, the site's change log may be invaluable to you, and it allows you to quickly get a little bit of a clue to a key doubt. Therefore, a manual recording and verification of Web site changes and changes in the log is a successful SEO can not be replaced by a good way.
