The current Google Sandbox unfortunately has two levels. You only get the trust of Google to get the ranking of web pages. In fact, considering that the webpage ranking isFashionEarly, because the web page must be indexed first to rank. Because, if most of your pages are classified as supplemental materials, you are not actually indexed!
Why is the page classified as "supplemental materials? Obviously, Google indexing page files is very picky. It is said that the only site she is interested in is those that are long-term and trustworthy.
"So what are the supplementary materials ?"
I will not learn from Google's official answer. I have summarized the following:
Google adds pages to Siberian cells.
Google's supplementary materials are opposite to normal Google indexes.
Google's supplemental materials will be given a very low level of trust.
Google supplements will not be used for any important rankings.
Now, assuming that your page has already entered Google's supplemental materials, there are five ways to help you escape from this hell as soon as possible.
Although it is extremely simple to give different titles to each page, many people still do not. We have no reason not to do so, which helps SEO, improve readability, and obtain high click rates.
Mark different META descriptions on each page. Remember that META tags are useless. No, Google is still using these tags. Let's not waste time. Just give a unique meta description to all pages, or even copy the title content to it.
Each page has a good unique content. This problem is very common for many reasons. The most common reason is that many content blocks are the same in different URLs. This is usually becauseWebsiteCMS or shopping cart, some pages or blank spaces with less content will also have such a problem, based on my experience (may not be authoritative enough, just my guess ), A page must have at least 100 characters to be unique.
