Mobile usage is growing fast, especially in North America, where it will soon outpace desktop browsing usage. Make sure your site loads fast and that it looks nice on all types of mobile devices. Be sure to not use Flash, and keep photos and videos to a minimum. Here are two useful tips from Google™ for optimizing your mobile site speed.

Take advantage of the opportunity to optimize your site for mobile visitors. We recommend the following options:

• Mobile CSS
• Meta Viewport Tag
• Apple Icon
• Mobile Redirection
• No Flash content

Great, your website directs www.nosaltresllegim.cat and nosaltresllegim.cat to the same URL.

Redirecting requests from a non-preferred domain is important because search engines consider URLs with and without "www" as two different websites.

Great! You have clean (user-friendly) URLs which do not contain query strings.
Clean URLs are not only SEO-friendly but are also important for usability.

Good, your website's IP address is forwarding to your website's domain name.

To check this for your website, enter your IP address in the browser and see if your site loads with the IP address. Ideally, the IP should redirect to your website's URL or to a page from your website hosting provider.

If it does not redirect, you should do an htaccess 301 redirect to make sure the IP does not get indexed.

Great, your website has a robots.txt file.

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.

Click here to check your robots.txt file for syntax errors.

Great, your website has an XML sitemap.

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.

It is also good practice to specify your sitemap's location in your robots.txt file.

Great, your title contains between 10 and 70 characters.

Make sure your title is explicit and contains your most important keywords.

Be sure that each page has a unique title.

Great, your meta description contains between 70 and 160 characters (spaces included).

Meta descriptions allow you to influence how your web pages are described and displayed in search results.

Ensure that your meta description is explicit and contains your most important keywords.

Check your Google™ Webmaster Tools for any warning messages on duplicate meta descriptions.

Meta keywords are used to indicate keywords that are relevant to your website's content. Because search engine spammers have abused this tag, however, it provides little to no benefit to your search rankings.

You can safely avoid the use of this tag for new web pages. For existing web pages, make sure the meta keywords do not appear to be spammy.

Great, your website is structured using HTML headings (<H1> to <H6>).

Use your keywords in the headings and make sure the first level (<H1>) includes your most important keywords. Never duplicate your title tag content in your header tag.

For more ‪‬effective SEO, use only one <H1> tag per page.

Alternative text (the alt attribute) is missing for several images. Add alternative text so that search engines can better understand the content of your images.

Remember that search engine crawlers cannot actually "see" images, so the alternative text attribute allows you to assign a specific description to each image.

Alternative text describes your images so they can appear in Google™ Images search results.

Check the images on your website and make sure ‪‬‬effective alternative text is specified for each image.

Restrict the number of characters in alt text to 150, including spaces, and minimize the size of images to optimize your website's page load times.

This page's ratio of text to HTML code is below 15 percent, this means that your website probably needs more text content.

A ratio between 25 and 70 percent is ideal. When it goes beyond that, the page might run the risk of being considered spam.

As long as the ‪‬‬content is relevant and gives essential information, it is a plus to have more of it.

Good, no Flash content has been detected on this page.

Flash should only be used for specific enhancements. Although Flash content often looks nicer, it cannot be properly indexed by search engines. Avoid full Flash websites to maximize SEO.

This advice also applies to AJAX.

Great, there are no frames detected on this page.

Frames can cause problems on your web page because search engines will not crawl or index the content within them.

Avoid frames whenever possible and use a NoFrames tag if you must use them.

Your website's PageRank is decent but it can be improved.

PageRank™ (commonly called PR) is a link analysis algorithm used by Google™ to assess the popularity/authority of a website. The PageRank goes from 0 to 10. New websites start at PR0 and authority websites, like Twitter.com, have a PR10.

Websites with a high PageRank are crawled more frequently and their outgoing links have more passing juice.

This is the number of pages on your website that are indexed by Google™.

The more pages that search engines index, the better, as this offers more opportunity for your website to be found.

A low number (relative to the total number of pages/URLs on your website) probably indicates that your internal link architecture needs improvement and is preventing search engines from crawling all of the pages on your website. You might want to create/check your site's XML sitemap and submit it to Google™. You must also build backlinks to your site's inside pages to help Google™ bots crawl and index your web pages.

Check Google™ Webmaster Tools under Health and Index Status, to keep track of the status of your site's indexed pages.

Your domain is old enough to encourage search engines to give it a higher rank.

Domain age matters to a certain extent and newer domains generally struggle to get indexed and rank high in search results for their first few months (depending on other associated ranking factors).

Submitting your website is important because search engines take DMOZ into account and sometimes display the company descriptions submitted to DMOZ in search results.

Keep your URLs short and avoid long domain names when possible.

A descriptive URL is better recognized by search engines. A user should be able to look at the address bar and make an accurate guess about the content of the page before reaching it (e.g., http://www.mysite.com/en/products).

Keep in mind that URLs are also an important part of a comprehensive SEO strategy. Use clean URLs to make your site more "crawlable" by Google™.

Resource: Search for a good domain name. If no good names are available, consider a second hand domain. To prevent brand theft, you might consider trademarking your domain name.

Great, your website has a favicon. Make sure this favicon is consistent with your brand.

Add a conversion form for repeat visitors. It could be used to sign up for a subscription, get an email address of a visitor or close an online sale. ‪‬‬Converting visitors into prospects/clients is probably the most important goal for your website.

After adding a conversion form to your site, it is important that you optimize your website to boost conversions.

Two of the main reasons for an increase in page size are images and JavaScript files.

Page size affects the speed of your website; try to keep your page size below 300 Kb.

Tip: Use images with a small size and optimize their download with gzip.

Your website is too slow. Slow page load time is one of the biggest complaints of web users.

If the load time/Kb is short, it means your homepage is too big.If the load time/Kb is long, this could be due to a server problem, a network problem, poor code optimization (cache, Mysql queries, etc.), or a third-party issue (advertising codes, analytics codes, etc.).

Site speed is becoming an important factor for ranking high in Google™ search results.

Great, you have declared the language.

Make sure your declared language is the same as the language detected by Google™.

Tips for multilingual websites:

• Define the language of the content in each page's HTML code.
• Specify the language code in the URL as well (e.g., "mywebsite.com/fr/mycontent.html").

Good, this web page takes advantage of Microformats.

A microformat is a technical semantic markup that can be used to better structure the data submitted to search engines.

Thanks to microformats, Google™ regularly improves its presentation of search results.

Your server's IP address has little impact on your SEO. Nevertheless, try to host your website on a server which is geographically close to your visitors. Search engines take the geolocation of a server into account as well as the server speed.

Use DNSstuff for comprehensive reports on your server.

It is important that your SEO efforts are not tarnished by spammy activities. Take care to avoid forum and blog spam and use best practices when sharing your content.

Great, your website is safe.

No evidence of phishing and/or malware has been detected.

Register the various extensions of your domain to protect your brand from cybersquatters.

Malicious bots scrape the web in search of email addresses and plain text email addresses are more likely to be spammed.

Great! Your server prevents visitors from browsing your directory by accessing it directly, this is excellent from a security standpoint.

Good, your server signature is off. This is excellent from a security standpoint.

Web analytics let you measure visitor activity on your website. You should have at least one analytics tool installed. It is also good to install one extra tool to have a confirmation of the results.

Analytics Tools: Google™ Analytics, Quantcast™, SiteCatalyst™, Piwik™, chartbeat™, Clicky™, ClickTale™, etc.

Get to know the technologies used for your website. Some codes might slow down your website. Ask your webmaster to take a look at this.

To fix the detected errors, run the W3C validation service.

W3C is a consortium that sets web standards.

Declaring a doctype helps web browsers to render content correctly.

Great, language/character encoding is specified.

Specifying language/character encoding can prevent problems with the rendering of special characters.

Deprecated HTML tags are HTML tags that are no longer used. It is recommended that you remove or replace these HTML tags because they are now obsolete.
