A crawl budget refers to the number of page bots from Google crawl and index on a website within a given timeframe. It affects how often and how many of your pages are indexed by Google. For example, if your website has a large number of pages but only a portion of them are indexed, it may indicate that your budget is being allocated inefficiently. This means that Googlebot is not spending enough time crawling and indexing important pages on your website, which could impact your search engine visibility. Another key aspect of this budget optimization is monitoring your website's log files to track how search engine bots are crawling your site. This data can provide valuable insights into crawl patterns, potential issues, and areas for improvement. When you understand and manage your crawl budget, you boost the chances of showing your content to your target audience.

Keyword difficulty is an SEO metric that predicts the effort required to rank on the first page of search engine results for a specific keyword. This metric is crucial for anyone involved in SEO as it influences the strategic direction of content plans and marketing campaigns—the higher the keyword "difficulty," the more challenging it is to rank for that keyword.

Domain Authority is a score developed by Moz that predicts how well a website will rank on search engine result pages (SERPs). DA is not an authority metric used by Google in determining search rankings but, instead, a third-party tool used for benchmarking and competitive link analysis. It is also a relative measure, meaning that it is most useful when comparing one domain's authority to another rather than as an absolute score of a website's traffic and performance.

Keyword ranking refers to the position of a website or webpage in the search engine results pages (SERPs) for a specific keyword or search term. It measures how well a website or webpage ranks compared to its competitors when someone searches for a particular keyword. When a website ranks higher in the search results, it's more likely to be seen by users. This can lead to increased organic traffic and visibility. That’s why businesses should pay attention to their keyword rank and strive to improve them.
