Page info

Here are those metrics that you should check when evaluating the quality of on-page SEO. Make sure that all these items are well optimized.

SEO Metrics

Meta title:

Find out if you’ve got a meta title tag on your page. There should always be a meta title.

Remember that it is vital to have a good one to capture the searcher’s attention on SERPs. With it, you also provide valuable information on what your page is about to both users and search engines.

Meta description:

Check if the page has a meta description. As with meta title, there should always be a meta description. An excellent one will tell users seductively what they can find on your page. It increases the CTR and lowers the bounce rate.

Meta robots:

See if Meta Robots is affecting your indexation. 

Does it have an index or noindex tag? Make sure it has the right tag.


Does the page have an Hreflang tag?

If your page provides content in several languages, you may consider using Hreflang. This tag helps search engines to differentiate a web page from its original version and allows them to display the language that corresponds to each user.


Does the page contain a canonical tag?

Think if you are duplicating the content of this page by displaying it on another page of your website. If the answer is yes, consider adding a canonical tag. This way, you’ll avoid Google Penalization for duplicate content.


Is it an AMP page?

Accelerated Mobile Pages, as the name indicates, help your pages load faster on mobile devices. Check if you are implementing the AMP on the page.

Http Headers:

Easily visualize HTTP headers

Every time your web browser opens a page, it sends a request that includes a series of HTTP headers. Instantly check which ones the current page is sending.


Does your robots.txt exist? 

Validate that your website is using a robots.txt file and that it returns a 200 status code. 

This is a must for GoogleBot to crawl your website.

Header Tags (H1-H6):

Visualize all your header tags so you can review them right away. Check if you have any short header tags to see if you can add any relevant keywords. All your H1 to H6 headers will be marked on the page so you can locate them quickly.

Page Links:

Get a list of links found on the page: Internal, External, Nofollow, Sponsored, and UGC.

Select the desired link type to mark it in the HTML. This way, you’ll quickly find out which links you have on the page. 


⛓️ Redirect Chains

Make sure you don’t have redirects or redirect chains. 

Get rid of redirect chains to avoid crawling issues and to prevent drops in Google Rankings.
