404 Error
An HTTP status code indicating that the webpage a user requested could not be found on the server. Frequent 404 errors can negatively impact user experience and crawl budget.

A link from one website to another. Backlinks from reputable sites act as “votes of confidence” for your website, signaling to search engines that your content is valuable and trustworthy.
Black Hat SEO
SEO practices that violate search engine guidelines to manipulate rankings. These tactics may provide short-term gains but are risky and can lead to penalties or even removal from search results.

Crawl Rate
The frequency with which search engine bots (like Googlebot) visit a website to discover new or updated pages. The crawl rate is influenced by factors such as: Crawl Budget: A search engine allocates resources to crawl a given site. Larger, more frequently updated sites tend to have a higher crawl budget.
