29 of the Best SEO Tools for Auditing & Monitoring Your Website in 2023
There’s nothing quite like a sudden Google algorithm update to leave you feeling equally confused and concerned.
There’s nothing quite like a sudden Google algorithm update to leave you feeling equally confused and concerned. It seems as though search engines like Google wait for you to get all of your ducks in a row and then unleash an update that makes your efforts instantly obsolete. Plus, there’s still some secrecy behind how Google evaluates websites and determines which sites appear — and how they appear — on the search engine results page (SERP) for different queries. The good news is that there are several search engine optimization (SEO) tools out there — some free, some paid — that can help you view your website the way search engines like Google see it. This way, you can improve your ranking and relevance for your target keywords. SEO is a complex beast with a lot of moving parts. So, it’s not surprising that there is a huge range of tools available to help you research, implement, and manage your website’s SEO performance. Some SEO tools help you perform very specific tasks. Others combine one or two areas of SEO together in multiple features. Finally, there are platforms designed to be a one-stop-shop solution for all your SEO activities. Broadly speaking, SEO tools fall into one or more of the following categories. These tools help you identify where your website is falling short from a technical perspective. They analyze site elements such as structure, metadata, page speed, and more so you can meet best practice guidelines from Google. From monthly search volume to related keywords, these tools help you identify which keywords you should target on your site. Typically, you start by entering some keyword ideas before the tools return lists of keywords, their search volume, and competition level. Most of these tools analyze the existing on-page performance of your content and provide recommendations on how to improve it for SEO. This will include the type and length of content required, comparisons to your competitors, topic ideas, and more. Backlinks are critical to sustainable SEO performance, and these tools give you clarity on your existing backlink profile. They also often provide ideas for websites you should seek backlinks from and how you measure up against competitors. Whether you want to keep track of progress at a high level or show off your SEO results to others in the organization, SEO reporting tools help you compile website data into actionable insights. They’ll usually enable you to build custom reports and track critical SEO metrics at both a high and granular level. Many tools and platforms incorporate multiple SEO tool types and features to provide everything in one place. With all-in-one platforms, you can use one tool to plan and manage your entire SEO strategy. For universal SEO tips you can use today to grow your business, check out our video guide below. These tools are free to use, but you might find a paid option that has more features. We’ve shared some of the best features in each tool as well as how you can get the most out of them for your SEO strategy. The goal of marketing is to generate traffic and qualified leads via the company’s website. That’s why, as marketers, we need to understand exactly what we can do to improve the SEO of that website. Hubspot’s Website Grader is a technical SEO tool that highlights how you can improve the speed, structure, security, and mobile performance of your site.

Core Features Google Search Console is primarily a technical SEO tool that helps you identify whether Google is finding and indexing your website pages. If it’s not, you’ll get guidance on why pages are not indexed and how to fix it. Google Search Console also has many tools available to help you appear in the SERPs for the search terms and phrases your target audience is looking for. If you’re the owner of a business or an SEO on your marketing team, Search Console can help you conduct an initial SEO analysis from scratch or update your existing SEO strategy with fresh keywords. Google Search Console monitors, debugs, and optimizes your website. Plus, you don’t need to know how to code to benefit from this tool. Core Features Google Analytics is a website reporting tool that you can use to gain insights into your SEO performance. It’s a great option for anyone looking for a free SEO reporting tool. Although Google Analytics has a paid version, the free version of the product can be paired with Google Search Console to provide a full picture of your SEO. In doing so, all of your website’s SEO data will be centrally located and compiled. You can use queries to identify areas for improvement with the keywords and phrases that you want your website and web pages to rank for. Core Features The free SEO Report Card by UpCity lets you analyze your website to determine how it stacks up against the competition.

Google Trends is a great place to explore untapped potential that can yield a large keyword landscape for your website. However, Google Trends isn’t where you’ll get granular data. This tool performs best when you use it as a compass to set a direction for your SEO strategy and then pair those insights with a more robust software like HubSpot’s SEO Marketing Tool. Core Features Seolyzer is a technical SEO tool that helps you determine how search engines like Google view your website. It includes free site crawling, log analysis, and reports so you can get ahead of potential crawling and indexing issues.

Core Features Check My Links is an off-page SEO tool that helps you monitor your backlink performance. The Google Chrome extension helps ensure your links on both external and internal web pages work. For instance, if you were to search a term on Wikipedia, Check My Links would be able to tell you how many links that Wikipedia page has in total and how many of those links are broken. This is helpful because you can make corrections to broken links immediately (or hopefully, before a page goes live). Check My Links is ideal for developers, content editors, web designers, and anyone else concerned with link performance. Core Features BROWSEO is essentially a technical SEO tool, although it also gives you quick insights into the number of backlinks on a page. BROWSEO allows you to review your web page in a limited format so you can analyze its UX and content as well as gain insight into its SEO.
