Site under the filter? Meet google filters.
And so, all about Google filters:
The Google Sandbox is a filter that is usually applied to young sites, but there have been cases when domains that have not been used for some time fell under this filter. The essence of this filter is that not a single young site can get to high positions in the search results for competitive queries until, so to speak, it is “infused”. However, it happened that some sites did not fall under this filter.
How to bypass the sandboxA: Google uses a trust rank system. The idea of trust rank is that if your new site is linked to by large sites that Google trusts, then your site will also be trusted. If you can get bold links from trusted sites (like DMOZ), you can quickly get out of the sandbox filter. If you cannot get links from trusted sites, then, for starters, you should try to optimize the site for less competitive queries, for medium and low frequency.
This filter includes sites that are promoted by ****th. If you make doorways, java and other redirects, you can lose 30 positions in the search results for all keywords.
How to bypass Google -30 : If you fall victim to this filter, you usually just need to remove the ****-elements from your site and the positions will come back to you.
This filter is used for sites that have a large number of external links with the same anchors. This link structure looks unnatural, so the filter sends such sites under this filter.
How to bypass this filter : If your site falls under this filter, then your site will most likely fall out of the index completely and it will not be allowed to be added again. Therefore, if you have purchased a lot of links with the same anchors, you need to immediately start diluting them with inaccurate entries, anchors with typos and just direct links to the site.
In fact, this is more likely not a filter, but a set of black optimization methods with which you can help the site get banned. Usually this term is used in relation to competitor sites in the search results. Google Bowling can only be used against young sites with a low level of trust. It will not harm large sites, and maybe even vice versa, it will help.
How to get around this problem : Google says there is nothing competitors can do to your site to harm its position. Many SEOs believe this, but we know that it is not. If thousands of back **** links began to appear on your site, then you should contact Google support and explain the situation that this is the work of competitors.
Duplicate content filter
This filter may include sites that host content that has already been created, hosted and indexed on other sites. Pages with duplicate content are generally not valued by search engines and therefore very rarely rank high. Most often, duplicate content ends up in an additional Google index, or does not get into the search index at all.
How to fight: if you are filtered due to duplicate content, then you need to either fix non-unique content to unique content, or simply remove non-unique content and start filling the site with unique content. If you are a source of unique content, and someone steals it from you and, as a result, your site falls under this filter (and this happens, since it is difficult for search engines to determine the source of information), then you need to contact the thief and ask remove content stolen from your site.
Optional Google Index
Google indexes the pages of your site and if it considers that the information on them is of poor quality, then it places such pages in an additional index. Google uses pages from the secondary index only when there are not enough results in the main SERP. In short, the pages that are in the secondary index will very rarely be able to bring visitors to your site.
How to get around : The method is very simple - you need to get links from trusted sites.
Additional Google results
Pages on your site that are in the extra results of the SERP will not be shown to users in the SERP until they click on the "Show more results" link. This link is on the last page of the search results, so it is very, very rarely clicked. A page gets into additional search results when it has duplicate content (or any other low-quality content) and no backlinks.
How to get out of the filter : You need to register meta tags, remove low-quality content and replace it with a unique one, get several external links to this page.
Google Trust Rank Filter
The Trust Rank algorithm, like PageRank, has many factors that determine the credibility of a site. Some of them are: the age of the site, the number of backlinks, the quality of the referring sites, the internal structure of the site, the structure of the url. All sites go through this filter, and if you have a low Trust Rank, then the positions in the search results will be appropriate.
How to gain Google's trust : get as many links as possible from trusted sites and directories, optimize your site competently, fill it with quality content, do not use black methods of site promotion and, over time, your site will be respected by the Google search engine.
Links.htm page filter (link filter).
This filter includes sites that have pages with a huge number of external links (link cleaning sites). Previously, this method of link exchange was used quite often, on one page there could be hundreds and even thousands of external links.
How to get rid of the filter : remove pages with link-washers, or reduce the number of external links to 10-20.
Link farms are sites or pages that contain a large number of links to each other, arranged in an arbitrary manner. Since Google rules prohibit artificially inflating the positions of sites in the search results, therefore, such sites and pages fall under the filter.
How to avoid the filter : The only way to avoid this filter is not to participate in link farms.
Filter for low-quality link donors
This filter monitors the quality of sites that link to you. If your car site is linked from casino sites and porn sites, then Google may decide that your site is related to porn and casinos and lower the position of the site in the search results. A poorly thought-out link exchange can not only be of no benefit, but also harm the site.
How to get rid of filter sanctions : When exchanging or buying links, carefully monitor donor sites and do not post links on porn sites. In addition, it is worth keeping track of mentions of your site using Google Alerts.
Filter for fast link growth
This filter is applied when a sharp, avalanche-like increase in the number of external links to the site begins. By suddenly starting to buy hundreds of links, you can get banned from Google.
How not to fall under this filter : wisely purchase links, especially for young sites. It should not be that your site has a couple of dozen links in a year, and then several thousand have been added in a week.
Filter for the appearance of a large amount of content
Google respects those sites that develop naturally. All sites that develop unnaturally fall under various filters of search engines. Some optimizers believe that if more than 5,000 pages appear on the site in a month, then the site may fall under the Google filter. Of course, it still depends on the size of the site, its search performance and the number of pages in the index at the moment.
How to get through this filter : If you are using any kind of content parser or generator, then limit its work, as the sudden appearance of a huge number of pages looks suspicious.
Filter for long page load time
The operation of this filter is very simple. If your site takes a long time to load, then the spider will not linger on it for a long time, which means that the pages of your site will not be indexed and will not be included in the search results.
What to do : Optimize your site's pages for faster loading. Remove unnecessary elements from the code, flash, java scripts. I recommend using services to check the speed of loading the site.
Filter for reoptimization
Too high keyword density, too dense linking, a large number of keywords in meta tags can lead to a filter for overoptimization. Optimize sites within reason.
Workaround : Don't over-optimize sites.
