Free browser extension

We like to share our knowledge! That’s why we keep publishing whitepapers on exciting online marketing topics and make them available for free. We also make your daily work easier with useful tools, like our extension for Google Chrome.

To the extension

Lately, we have missed a browser plugin that was very popular at our agency. It was called sitemetrics and made for example tag and other metrics visible after one click when surfing websites. This made our work easier every day, because we didn’t have to open the source code on every subpage and then search for the title tag when we wanted to get an overview.

sitemetrics – unfortunately no longer available

Unfortunately, this extension has not been available via the Chrome Web Store for a while. Therefore, we decided to build a similar tool – eology site metrics. Our version has as well similar features as sitemetrics, but also some completely new ones that are interesting for our SEO work.

Only the source code of the website and its HTTP headers are read.
The extension outputs:

We use this tool internally, but also make it available for free to any Chrome user via the Chrome Web Store. Click here to go directly to the extension.

But what can you do with the information that the extension outputs? That is briefly summarized here:

The title tag is still an important ranking factor for Google. Think about the term / topic for which you want to rank with your subpage, and put this information in the title tag. Since the title tag is often used as a headline in the search results, you can also show the user immediately what your page is about. You should also pay attention to the length of the content when filling the title tag. That’s why our browser extension eology site metrics also indicates the number of characters of the stored information. The length is measured by Google using the pixel width, but the characters also give us a good guideline. For the title tag, you can orientate yourself on a character length of about 55 characters.

Meta description
The description is not a direct ranking factor, but it is often used in the search results as a description of the website. Thus, you can influence the click rates (these are ranking factors) on your search result via the description. Give the user a short summary of the website’s content in the description and encourage him to click. Again, our extension gives not only the content, but also the character length of the information stored in the source code. Orientate yourself at a length of approx. 156 characters.

Here the URL of the subpage you are on is displayed. Of course you can see this in the browser, but this way you can always see which page you had looked at, e.g. if you make a screenshot of the extension for documentation.

URL of the Robots.txt
Here is shown, under which URL the robot.txt file of the domain is located. There are possibly instructions for search engine robots stored, which one should look at in any case once when analyzing web pages.

Meta Robots
Here it is checked whether information is stored in the meta robots tag in the source code, and if so, what this information is. There you can define for example the values index (page should be indexed), follow (the crawler should follow the links on this page), noindex (the page should not be indexed) and nofollow (the crawler should not follow the links on this page).

X-Robots tag
The mentioned information from the meta robots tag can also be stored in the HTTP header of the page. Therefore, an additional check is made here to see whether information about this is stored in the HTTP header.

Canonical meta
At this point it is displayed whether a canonical tag is set and whether it refers to itself or to another URL. To do this, you can simply compare the URL displayed here with the URL that is displayed above at URL. By Canonical Tag you can point to another URL if it has the same content and is the original resource. One would see here immediately, if such a tag was set by mistake and could recognize, why the analyzed page is possibly not found at Google and Co.

Canonical header
Basically the same information is displayed as with canonical meta. You can define this canonical information not only in the HTML code, but also via the HTTP header. Here it is checked whether a canonical is stored in the HTTP header.

Content encoding
Here it is indicated whether and which kind of content encoding is used. It is therefore a question of whether the content is compressed. The use of such techniques can have a positive effect on the loading time.

Here you can see which protocol the page uses. Is the page already using HTTP/2? Namely, this has some advantages that positively affect the loading time.

With these key figures / information, problems with indexing / ranking of individual subpages can often be quickly detected. In addition, information such as the title tag or the meta description is displayed quickly and clearly.

We hope that not only our team will enjoy this helper and wish you a lot of fun in your daily work with it. If you like the browser extension, we are of course happy about a review in the Chrome Web Store.
