The concept of spiders
Having software called spiders in search engines can be a very interesting topic for users. Many users may be wondering what the spider has to do with search engines and SEO. To answer this question, we need to analyze the performance of the spider in the main world to discover its similarity in the real world and the virtual world of the Internet. Spider-Man jumps from building to building and wall to wall, dismantling tall buildings. In the virtual world of the Internet and search engines, when optimizing sites, crawlers and spiders inside search engines go to the site and other pages through in-site links. In other words, the links on sites and pages act like spider webs, and spiders go from page to page and from site to site through the same links. Spider is software that has been placed inside search engines and optimized to go to various pages and sites through links and optimize their content.
Crawlers are software that follows the links on pages as an algorithm to reach different and related pages and index their contents for search engine databases so that the search engine database is always up to date and can After the user search, display the result easily and quickly for the user.
Spiders are software that scrolls from page to page, scanning and indexing their contents. The links that spiders use to go to other pages are called feeds. Spiders use the links on the pages as a webbing thread. Here we can understand the importance of internal and external linking, and site owners need to be careful about linking for their site pages to be better indexed and placed in search engine databases.
How spiders and crawlers work
Spiders use it to index the pages of your website through links on various pages. Spiders work according to certain policies. Their work policies are as follows:
- Selection Policy:
One of the policies that spiders use to select pages from the website to be indexed. This means that they use this policy to determine which website pages should be indexed.
- Re-Visit Policy:
A policy used to review and revisit web pages. As web pages are first viewed and optimized by search engines and then placed in a list, it is up to the spiders to revisit and rediscover which web pages in the list should be revisited. Be re-examined, and this diagnosis is made using this policy. In other words, this policy is used when crawlers have indexed page content and placed it in database directories. Still, for better and easier access, they should check the links in the database, which The review is done through this policy.
- Politeness Policy:
This policy is used when search engine crawlers and spiders notice no overload. Of course, reptiles are very sensitive to this issue and focus a lot so that the page being examined does not have duplicate pages, so that duplicate pages are not indexed again.
- Parallelization Policy:
This policy, which is the last stage of reptile operations, is about how reptiles and spiders are distributed on sites and pages and cause them to coordinate on how to disperse and perform operations. Of course, in this type of policy again, great care is taken not to index duplicate pages.
How crawlers work to index web pages is divided into three steps:
3- search engine
In the first stage, reptiles go inside all the contents, posts, and posts of different types of sites and crawl between them to get enough information and store it in the database.
In the second stage, the information obtained from the crawling stage is placed in the database and stored so that in the last stage, when users search, search engines can find the appropriate and desired result of the user from the database and provide it to users.
Factors affecting how reptiles work:
1- Domain name:
The importance of domain name based on new Google algorithms such as the Panda algorithm is very high, and domains that have keywords will have special importance and privileges in ranking and ranking. Domains that rank well and have Google ratings are more likely to scrutinize search engine crawlers.
As we have said in other articles and other sections, backlinks and external links are very important in being in the top rankings and ranking your pages well by search engines. And if Google gets it, it's better to use principled linking. If the linking of your site is not principled, it may even have negative and bad effects on your site. The links between the contents of the pages are like algorithms that crawlers follow to go to other pages. To index your pages by crawlers, you need to use basic linking.
3- Internal links:
Internal linking is used to direct the user from one page to another site page. If your linking is principled, you can keep the user on the site for a long time and make them see other pages of your website. Principled internal linking is very important in directing crawlers to other website pages to index content and store it in search engine databases.
After placing your site on the servers, it is better to specify your sitemap
5- Duplicate content:
Duplicate content is not suitable for Google and SEO, and if you see duplicate content, negative points will be considered for the site. Even reptiles are very sensitive to this issue and will not be indexed according to the Politeness Policy if faced with duplicate content.
6- Meta tags:
Using more common meta tags and tags has no effect on the appearance of the content but will help crawlers more in indexing web pages. Meta tags have a great impact on identifying sites to search engines and optimization.
