The free SEO Check

Compliance with search engine guidelines is an important factor in SEO success and therefore the ranking of a website. The SEO Checker checks your website and shows you errors and problems that prevent a good ranking. Search engines like Google now use several hundred ranking signals to evaluate a website. However, various technical SEO factors must be error-free for a URL to even have a chance of a good ranking.
The Buddler SEO Check is free and checks more factors than any other SEO checker. You can analyze your site, then make improvements and just do an SEO analysis again. Each URL can be checked any number of times. You can simply create a PDF from the finished analysis or save the URL of your personal SEO check to work with it later.

How can you improve your rankings in Google
with an Free SEO checker

Even though search engines like Google try to crawl and scan every website properly, it's not as easy as it might sound.
A URL that should rank for a search term in Google must be accessible, it should load quickly and include a reasonable amount of text, images, lists, and tables (where appropriate).
This can all be checked by yourself or with an SEO checker. However, most SEO tools check other factors that are not obvious to a normal user. If, for example, a URL is blocked in robots.txt or if it has a "noindex" tag, it cannot be found using a search engine.
If the content of the URL is repeated or if the page takes a long time to load, it is true ranking possible, but it will be difficult to appear in the top 10 search results. If a page isn't optimized for mobile and tablet, the page may rank decently on desktop but not show up in a mobile search. So an SEO checker can help you with all of that uncover and fix problems.

Which SEO tool do you need?

In order to optimize your website and thus achieve better ranking results, you usually do not need expensive SEO tools. The free SEO tools now provide a wide range of functions. As mentioned above, you should first log into the Google Search Console. Once you have understood the results displayed in the Search Console and corrected them if necessary, you need to think about which keywords you want to rank for. An SEO tool such as Buddler Ultrasuggest is suitable for this. To check more than one site at a time there is SEO Crawler, it shows you all the technical problems and errors that a search engine can have with your site. To write good text, you need to think about what your audience expects from your content. Always design and write your content for users, ideally better than your competitors and add images, videos, tables and lists to the text. The Content Briefing Tool can help you with this.
After you have put a lot of work into your site, you can also monitor the rankings of the search results. Search engines make frequent updates and rankings can fluctuate accordingly. I use the Keyword Monitor to monitor the ranking of a domain and its keywords.

Frequently Asked Questions

What is a SEO Check?

An SEO checker is a tool that checks your website for technical errors or problems with search engine optimization. These tools act like a search engine when fetching the page. As a result, they create a list of all tested SEO factors and show where pages need to be optimized.

Why do an SEO check?

With a good SEO checker you can see at a glance whether a search engine can easily index all the content on the page. The check is a quality assurance for publishers, bloggers and a standard in online marketing.

How does an SEO check work?

An SEO Check is software that behaves like the Google Crawler / Google Bot. The software tries to imitate Google's behavior and also makes all problems that can arise visible to the user.

How can I verify an entire domain?

There are so-called SEO crawlers for this. These follow links within pages and thus crawl (crawl) through a website. The results are far more comprehensive than with a normal SEO check, since a large number of pages usually have to be analyzed.

What do I do with the result of the SEO check?

That depends on your level of knowledge of HTML and web technologies. Many errors and problems can usually be fixed in the blog software, the shop or the CMS itself. In addition, you can contact a web developer and ask them to fix the errors.

Why is an SEO score not useful?

When technical tests are represented in just one number, it is possible to get a high score but still have serious errors on the website. It is safer and ultimately better to look at all errors in detail.

How do I start with search engine optimization?

Ideally, you have a website that you want to optimize. You think about which keywords you want to rank for and start to integrate a good, high-quality and extensive text on your site. Use an SEO check to find errors and try to fix the errors. It's not easy at first, but over time you'll understand more and get better at SEO.

What is the difference between technical SEO and content SEO?

Technical search engine optimization ensures that a page can be crawled quickly, that all important meta information is available and that there is nothing standing in the way of the success of content SEO. Content SEO affects everything a user can see or read on a website, i.e. text, images, videos, etc.
