This is an example of what your Title Tag and Meta Description will look like in Google search results.
While Title Tags & Meta Descriptions are used to build the search result listings, the search engines may create their own if they are missing, not well written, or not relevant to the content on the page.
Title Tags and Meta Descriptions are cut short if they are too long, so it's important to stay within the suggested character limits.

WWW Resolve
Ωραία, υπάρχει μια ανακατεύθυνση για την ανακατεύθυνση της επισκεψιμότητας από τον μη προτιμώμενο τομέα σας.
Redirecting requests from a non-preferred domain is important because search engines consider URLs with and without "www" as two different websites.

Χάρτης ιστότοπου XML
A sitemap lists URLs that are available for crawling and can include additional information like your site's latest updates, frequency of changes and importance of the URLs. This allows search engines to crawl the site more intelligently.
We recommend that you generate an XML sitemap for your website and submit it to both Google Search Console and Bing Webmaster Tools. It is also good practice to specify your sitemap's location in your robots.txt file.

Robots.txt
A robots.txt file allows you to restrict the access of search engine robots that crawl the web and it can prevent these robots from accessing specific directories and pages. It also specifies where the XML sitemap file is located.
You can check for errors in your robots.txt file using Google Search Console (formerly Webmaster Tools) by selecting 'Robots.txt Tester' under 'Crawl'. This also allows you to test individual pages to make sure that Googlebot has the appropriate access.

Καλά, όλα τα URL φαίνονται καθαρά και φιλικά
Your site's URLs contain unnecessary elements that make them look complicated.

Clean URLs are also useful when shared on social media as they explain the page's content.

While there's no exact limit to the number of links you should include on a page, best practice is to avoid exceeding 200 links.
Links pass value from one page to another, but the amount of value that can be passed is split between all of the links on a page. This means that adding unnecessary links will dilute the potential value attributed to your other links.
Using the Nofollow attribute prevents value from being passed to the linking page, but it's worth noting that these links are still taken into account when calculating the value that is passed through each link, so Nofollow links can also dilute pagerank.
