SEO audit: not an exact science
There’s a reason why there’s no one-size-fits-all approach to a successful SEO audit. It’s also why SEO “best guidelines” are sometimes inconsistent. Google is an enigmatic beast. It alters its algorithm on a regular basis and rarely explains why or how it did so.
🧾 Glossary
What is a Site Crawler?
Search engines have their own site crawlers; for example, Google has its “Google bots.”
These bots, commonly known as “crawlers” or “spiders,” go over new or updated websites, examine the content and metadata, and index the content collected.
You may also utilize third-party web crawlers as part of your SEO strategy.
These site crawlers may examine the health of your website as well as your rivals’ backlink profiles.
What are XML sitemaps?
An XML sitemap is a file that lists a website’s important pages, making sure Google can find and crawl them all. It also helps search engines understand your website structure.
What is Robots.txt?
Robots.txt is a file connected with your website that tells web spiders whether or not to crawl certain parts of your website.
What is a log file?
A log file is a text file that records all of a server’s queries, both from people and crawlers, as well as its answers to those requests.
What are Core Web Vitals?
Web Vitals is a Google effort that was started in May 2020 with the goal of providing uniform recommendations for quality signals that are critical to providing a great web user experience.
What are orphan pages?
Web Vitals is a Google effort that was started in May 2020 with the goal of providing uniform recommendations for quality signals that are critical to providing a great web user experience.
How does on-page SEO work?
On-page SEO is related to topics like:
- Optimization of title tags, meta descriptions, and H tags
- Image alt tags
- Producing content that is optimized
- Internal linking
Final words
Because each tool we’ve discussed has its own unique twist, I highly advise you to use many at once. And, fortunately for you, many of the greatest SEO audit tools are available for free.
