Search engines have a purpose that will not change easily, which is to provide users with useful and relevant information. No matter how search engine indexes and rankings change, this purpose will not change significantly within a certain historical period. If any search engine deviates from this fundamental purpose, it will not be far from failure.
SEO personnel also have the same purpose when optimizing the website, providing users with a large amount of content that is useful, relevant to the website theme, and preferably original.
SEO also has its place in keeping pace with the times. Search engines are getting smarter as their crawling, indexing, and ranking algorithms improve. It can detect more cheating techniques, determine the relevance of a file to keywords through a variety of methods, and also detect whether the file is useful to users.
In the process of improving this algorithm, SEOs must always pay attention to what new factors have been added to the search engine algorithm? What changes have occurred in the weight of ranking factors?
In the early days of the SEO industry, seven or eight years ago, the most effective technique was keyword stuffing. It is enough to put a large number of keywords in the title tag, keyword tag, and body of the web page, sometimes even keywords that have nothing to do with the content of the web page. Within a few days, your website may be ranked on the first page for popular keywords.
But before long, most webmasters who know a little bit about SEO realized that search engines give great weight to title tags, keyword tags, and high keyword density, so everyone began to abuse these tags and began to pile up keywords. Search engines The quality of search results began to decline as a result. Alta Vista, the largest search engine at that time, equivalent to Google today, was destroyed in this way.
Then Google invented the web page level and a new algorithm based on connection relationships. Simply put, the more external connections there are, the higher the ranking. Soon everyone discovered the loopholes in this algorithm and began to create a large number of spam links. They left various irrelevant links in guestbooks, forums and other places. They bought and sold PR, bought and sold links, created a large number of connection factories, registered a large number of domain names and then connected to each other. Get up and wait.
In response, Google also began to fight back, adding a series of countermeasures such as the sandbox effect. Yahoo also has a similar delay effect, but it is not as strong as Google. With the sandbox effect or time delay effect, the effect of external connections appears to be slower. Some cheaters have lost their patience and do not use this method very much.
At the same time, search engine link analysis technology continues to improve, able to detect which links are meaningful and which are cheating techniques.
However, it is undeniable that machines are not as smart as people. People can tell at a glance which connections are purely to increase connections and deceive search engines, and which connections are meaningful voting behaviors. Search engine spiders are still far from this step, so there are still countless cheaters creating a large number of spam connections every day.
Nowadays, search engines are increasingly analyzing user behavior patterns and user interaction with websites. Webmasters should invest in aspects such as website usability, bookmarks, excerpts, wikis, link click-through rates, page browsing time, and user interaction on the website. More energy.
A qualified SEO personnel should have a full understanding of the history of changes in these SEO methods, and more importantly, be sensitive enough to the latest trends.
Many people are still discussing how to create spam links to deceive search engines. What is certain is that these methods may still work today, but they may not work tomorrow. It is better to spend your time on making an excellent website.
