Google – how it works
With the help of crawlers (also called bots, crawlerbots, Googlebots, spiders, searchbots, or web crawlers), pages are indexed and entered into Google’s database. A crawler is a program that independently visits pages on the Internet, analyzes the pages and transmits the results of the analysis to Google’s database. The crawler works its way through linked URLs from page to page. This means that only pages that are linked to on other pages are recorded.
If the information from the bots is in the database, it is further evaluated there. Several algorithms and criteria then decide how well a website “ranks” and how it is “sorted”, i.e. indexed. This then decides where the pages are for a particular search query, i.e. how the pages are sorted according to a search query.
The best-known algorithm for this sorting is the so-called “ PageRank ”, named after Google’s co-founder, Lawrence Page. In addition to this, there are a number of other criteria that affect both the page itself (OnPage) and the position of the page in relation to other pages (OffPage).
The exact way in which the search results are determined and sorted is a trade secret of Google. However, tips, suggestions and “best practices” are regularly published to help pages rank better in the areas of OnPage and OffPage. Various analysis tools, strategies and findings from the SEO scene also help so that a website ranks or is indexed better.
What is Google Dance?
Google Dance: The continuous dance of search results. In order for you to get results of the highest possible quality for your search query, search engines have to update your database regularly. In the past, Google usually updated the index every four weeks. During the re-indexing, the search results were very noticeable because they fluctuated (danced) for several days between the old and the new index. The PageRank of a website also fluctuated between different search results. This is why the search engine’s index update was called Google Dance. Today the Internet is crawled several times a day for new content and web pages searched and the index is adjusted daily. The Google Dance no longer exists in this form. Sometimes one speaks of Google Dance when there is a major change in a search result for a website – in any case, nowadays you should do a thorough SEO check if there are noticeable differences in the positioning.
Why was there the Google Dance?
In the early days of Google up to the first years after 2000, the Google Dance took place monthly and caused troubled times for many SEO managers. Because between the dancing placements of one’s own pages in the PageRank of the search engine, it was impossible to foresee which placement would be expected after the Google Dance had calmed down.
These phenomena arose because the many thousands of servers that carried out the (new) evaluation and subsequent listing of the many millions of websites could not do this at the same time. If the monthly change was made to the algorithm and uploaded to the servers, some of them already had the new rankings due to the new evaluation basis, while the other servers had not yet uploaded this as an evaluation basis. Until all servers were at the same level of the ranking criteria, the results “danced” – even with the same keyword. The search queries could have very different results even within days – this phenomenon was given the name “Google Dance”.
Why is the Google Dance no longer available?
With the growing numbers of about crawled n Webs e th and thus to-value ranking factors Google introduced its indexing strategy to. For search queries that are answered as up-to-date as possible, the crawling by Google is constantly being improved. Initially there were gradual changes, but with the Google Caffeine update a very clear change could be observed. Originally all pages were scanned and evaluated piece by piece, but since the caffeine Update Google constantly and in parallel, various influences and factors for the ranking are recorded and are constantly and up-to-date included in the pageranking.
This crawling process is very topical and never completely finished, as the innovations are always incorporated into the algorithm, new pages have to be crawled and influences from evaluation criteria such as backlinks or signals from social media flow into the current placement. Google itself has stated that Caffeine processes hundreds of thousands of pages in parallel per second in this way. The memory required for this is almost 100 million gigabytes of memory. And hundreds of thousands of gigabytes are added every day.
Because of this simultaneity, there was no longer any Google Dance on the search engine.
