Many times, we will exchange links with other websites, but sometimes we will want to add some hidden links or hidden text. When it comes to the specific time, it depends on everyone's personal ideas. Currently, hidden text is regarded as a kind of cheating by search engines. Once the behavior is judged as hidden text by the search engine, the authority will be demoted or the website will be blocked. Therefore, you must be cautious when adding hidden text or hidden links. In fact, there are some relatively safe methods.
I have a website that was hacked and added some hidden text links. As a result, it was discovered by Google. It said that hidden text was found and did not meet the quality requirements. As a result, the website was deleted from the Google index. Such hidden links are If it is discovered by search, what kind of hidden links or hidden text are easy to find, and some will not be known by search engines at all.
In fact, search engines so far cannot parse JS and CSS. Google can only parse some simple output of js, but for html tags, all search engines can recognize it. Understanding this, we Just know that pure HTML such as <font style="position: absolute;overflow: hidden;height: 0;width: 0"> using attributes to add hidden text or hidden links is like committing suicide.

There is a relatively safe way to add hidden links. Using js and css, you can add hidden links very safely, such as:
<div id="a">inflatables</div> Then the next step,
<script language=javascript>document.getElementById("seoplus").style.display="none"</script>
This completes the hiding of the text. Use JS scripts to get relevant elements based on ID numbers and control their style attributes to be invisible. With this method, so far, no search engine has been able to find the problem, including Google. Such hidden links are currently the only one that can be found. It’s the safest so far.
