When a website strives to make it onto the front pages of the particular SERPs through which it hopes to attract web traffic, it must pursue all available methods of SEO that Google's ranking algorithms are expected to react positively to. Auditing software is highly useful for gauging whether the website's SEO efforts are uniformly strong and conform with the most recent standards, and it can represent different aspects of those efforts as separately scored categories.
A Google-affiliated browser extension called Lighthouse, which can be installed in Google's own Chrome browser, can be used to gauge the likelihood that a given website's design and execution would be recognized by the ranking algorithms as compliant with standards. While it assigns a score to what it perceives to be the site's efforts to have its coding and technical structure adhere to established SEO ideals, it also assigns scores to factors that more directly affect the user experience. If a website does not load and render its assets quickly as the user follows hyperlinks, Lighthouse is sure to give it a low "Performance" rating. Lighthouse can also be expected to give lower marks for "Accessibility" if the website has not made sure to include code and functionality that would let it be more readily usable by readers with impairments such as color blindness and dyslexia.
Lighthouse can be used to generate grades not only for one's own website but also external sites. Perhaps unexpectedly, if Lighthouse is used on the website of one of the most ubiquitously recognized brands on the planet, it might reveal a site that technically fulfills all checkboxes pertaining to SEO and accessibility requirements but otherwise falters in performance. If the brand in question runs a complex multinational storefront, then the website used to sell these products to consumers worldwide is more likely to load somewhat sluggishly between pages. For any small business, the algorithms would dock its page rankings on account of this. However, the privilege often enjoyed by veritable titans of the corporate space ensures that their storefronts will stay on the top positions of SERPs regardless.
