Keyword stuffing

Irrelevant keywords, such as keyword attempts. or unnaturally too many numbers And how do we know that we have the right keyword, can be calculated according to this formula

Good keyword quantity = number of characters in the article/number of keywords (duplicates) in the content that the right amount of keywords, that is, should not exceed 1 - 2% of the article itself.

3.    Have the right amount of keywords (up to 2%) and natural.

Link incorrectly, for example, content is one subject and inserts a link to another page or other unrelated website. For example, if a website is being renovated, use 301 or 302 redirects and make sure the website Does our site have sneaky redirects at google search console: Fetch as google boot

Doorway page

A website built to get high rankings in keyword searches, including useless pages. Not relevant to the searcher, such as multiple domain names, multiple pages with cities, numbers, or anything to facilitate the link to any website.

Hide or close paths, deviate, prevent them from going to the actual web page for any benefit. such as trying to create content to limit or divert access Avoid google from ranking or surveying your website.

Thin Content

too little content That doesn't mean it's a bad article. But the article that is not useful at all is this kind of article. because of that If you don't want your article to be meaningless. You should avoid doing these things.

1.    Copy the villagers to paste It's better if you try to create an article. Your own story and then link the references or sources.

6.    Content generated by AI or get content in another language. like English Then put it in google translate and paste it on our website. Eh, this is not very good at all.

7.    All Affiliates should create their content, review, or do what to do. to attract people to buy that product without copying him and pasting it stubbornly The type that does not have any content related to or linked to our products and website at all. If you think of being an Affiliate, it's fair to say that this will sell or tag him or nofllow like this is better. Nah

8.    The website that oh… is the same owner. But pretending to not know each other, but using the content to be linked together until it is unnatural, this is AI google, he knows.

9.    Make an effort to find references or references that own it. It's better than picking up someone who didn't create the content themselves. But take another reference. To spin this link, it does not take.

10.    Page experience update

1.    Core Algorithm Update

overlord!! The main AI has also been adjusted, so what has been modified? It is still the same pattern that this update has a significant effect on the SERP.
