Passing Score for A SEO Professional : Important SEO Tools

Don’t stare at Title: 33 is the minimum passing score according to our education system, and we all struggled a lot for getting 33%. This post makes memorized my childhood with border line of 33. I personally love these tools. So with the help of webgnomes (where I saw this post)  I am sharing these with you…

If you like SEO tools and you’re a fan of free stuff, you’re going to LOVE this list of free SEO tools. The list is organized into 11 categories, and each category broadly describes a popular SEO task (e.g., Backlink Investigation, Keyword Research, SEO Analysis, etc.).

I’ve included a brief overview of each tool’s free functionality (some of the tools are freemium), screenshots, videos, and links to documentation for the more complex tools. Hopefully, this resource will give you everything you need to start mastering these amazing tools.

So without further ado, let’s jump into the list…

I). Backlink Investigation

For years, your site’s backlink profile played a vital role in your site’s ability to rank well in the search engines. Now, in the post-Penguin era, that backlink profile is more important than ever. With that in mind, the following free SEO tools will help you investigate a site’s backlink profile.

1. Open Site Explorer

Open Site Explorer
After Yahoo! Site Explorer’s untimely demise in 2011, Open Site Explorer (OSE) became one of the most popular backlink checking tools. OSE uses the freemium model, and without an account, you are limited to running 3 reports per day.

The following screenshot shows an example report:

Open Site Explorer results

If you register for a free account, you have access to 1,000 backlinks for a given URL, and the first 15 backlinks include additional information such as the link’s anchor text, Page Authority, and Domain Authority. Each report also includes summary information about the requested URL: its Page Authority, Domain Authority, number of linking root domains, and number of total links.

2. Majestic SEO Site Explorer

Majestic SEO Site Explorer
Majestic SEO Site Explorer is another popular backlink checking tool, and like OSE, it uses a freemium model. Without an account, you are only able to access general summary information about a requested URL or domain (e.g., number of referring domains, number of external backlinks, number of referring IP addresses, etc.).

If you register for a free account, you receive additional summary information (e.g., a backlink breakdown), and you also get access to the top 5 backlinks, top 5 referring domains, and top 100 pages (based on the number of referring domains) for your request.

For more information, read Julie Joyce’s Majestic SEO review.

3. Ahrefs Site Explorer

Ahrefs Site Explorer

Ahrefs is one of the newest backlink checking tools, but it already has a very loyal user base. Similar to most of its competitors, the tool uses a freemium model.

As a guest, you are allowed to perform 5 requests per day, and if you register for a free account, that allowance increases to 15 requests per day. Each request returns a backlink overview as well as specific information about individual backlinks (for free accounts, only the first 5 backlinks display additional information).

The backlink overview includes information such as the total number of backlinks, the number of referring domains (and a corresponding TLD breakdown), and a breakdown of the backlink types (e.g., text, image, nofollow, etc.).

For a given request, free accounts receive access to the first 500 backlinks. The first 5 backlinks display the link’s Ahrefs rank, source URL, source title, destination URL, anchor text, type, and crawl date. However, the remaining backlinks only display the link’s Ahrefs rank, source URL, and source title.

For more information, check out Eric Covino’s Ahrefs Review.

4. Link Diagnosis

Link Diagnosis

Link Diagnosis is a completely free backlink checking tool, but unless you install the corresponding Firefox extension, you will only receive a limited view of the results (the “lite report”). Without the Firefox extension, the tool displays the first 250 backlinks, along with each backlink’s anchor text, mozRank, Page Authority, and Domain Authority.

With the extension installed, the 250 backlink restriction is removed, and the tool presents each backlink’s title (i.e., the title of the linking page), link type (e.g., nofollow), PageRank, outbound link count, modified outbound link count, and LinkStrength (in addition to the information displayed without the extension).

II). Server Investigation

When diagnosing an SEO issue, it is often useful to investigate the site’s Web server. Whether it’s identifying a server’s technology stack, uncovering the source of performance bottlenecks, or troubleshooting HTTP headers, the following free SEO tools can help.

5. BuiltWith

BuiltWithvvvvv
BuiltWith provides a technology profile for a given site, which includes information about the site’s server, frameworks, advertising, analytics, JavaScript libraries, and much, much more. You enter a website’s URL, and the tool essentially performs a technology X-ray.

Here’s a screenshot of the tool’s technology profile:

BuiltWith technology profile

The tool also provides a simple SEO profile, which checks a page’s title, meta description, H1 tag, content keywords, images, response speed, and social sharing.

6. Pingdom Full Page Test

Pingdom

Pingdom offers a free online tool that analyzes a URL’s load time. You simply enter a URL, and the tool displays a summary of the page’s load time, size, and number of corresponding HTTP requests.

Here’s a screenshot of Pingdom’s results:

Pingdom results

As the screenshot shows, the tool also presents a waterfall visualization that displays the load time and size of each of the page’s objects.

7. Google PageSpeed

Google PageSpeed

PageSpeed is a free online tool (plugins are also available) that tests a URL’s load performance. You enter a URL, and then, the tool presents a list of performance-based suggestions (e.g., optimize images, minify JavaScript, etc.), which are categorized into high, medium, and low priority items.

8. URI Valet

URI Valet
URI Valet is a free online tool that displays the HTTP headers exchanged during a request for a given URI. The tool also presents a summary of the corresponding HTML’s <head> tags and a breakdown of the various objects (e.g., scripts, images, etc.) that are downloaded when accessing the URI.

9. SpyOnWeb

SpyOnWeb
SpyOnWeb identifies multiple sites that probably belong to the same owner. On the backend, the service clusters sites that share an IP address, Google AdSense ID, Google Analytics ID, Yahoo! Publisher Network ID, or Yandex.Direct ID. Then, when you query a website’s URL, the tool presents a list of sites that have been clustered together with that URL using the previously listed information.

III). Website Crawling & Link Checking

One of the best ways to identify SEO-related problems with your site is to crawl its pages and look for issues. These issues can be markup-related (e.g., duplicate titles), or they can be link-related (e.g., broken links).

10. Screaming Frog SEO Spider Tool

Screaming Frog
The Screaming Frog SEO Spider Tool is a freemium desktop application that allows you to crawl and analyze the pages on your website. The tool is free for the first 500 URI requests and £99/year after that.

For each request, you receive a wealth of information, including the page’s title, meta description, heading tags, image info (e.g., alt text), link info (e.g., are they nofollowed), and much, much more. Rather than bombard you with screenshots, here’s a video that demonstrates the tool’s functionality:

11. Xenu’s Link Sleuth

Xenu Link Sleuth
Xenu’s Link Sleuth is a free desktop application that checks for broken links on your website. The tool also displays page titles and meta descriptions, but its primary purpose in life is to quickly crawl a website and identify the status codes of the site’s links.

12. W3C Link Checker

W3C Link Checker

Link Checker is a free online tool that checks the validity of links for a given URL. You simply enter a URL, and then, the tool recursively checks the URL’s links for URI scheme errors, redirects, and error status codes.

IV). Content & Markup Analysis

Your site’s on-page ranking factors are derived from the site’s content and markup. Consequently, it’s extremely important that you optimize the content and minimize errors in the markup.

13. SEO Browser

SEO Browser

SEO Browser is one of the oldest free SEO tools, but it is still incredibly useful. The tool is 100% free, and it offers two modes: Simple and Advanced. The Simple mode displays a given URL like a text-based Web browser (e.g., lynx). The Advanced mode provides a text-based view of a URL, and it also includes useful information that summarizes the URL’s content (e.g., page title, meta tags, page size, word count, IP address, etc.).

14. Copyscape

Copyscape
Copyscape is an online duplicate content detection tool that uses a freemium model. You simply enter a page’s URL, and the tool returns a list of pages that are duplicating the URL’s content. With a free account, the tool only displays the first ten results, and the tool only allows a certain number of monthly requests for any given site (this limit is irrespective of the IP submitting the request).

15. W3C Markup Validation Service

W3C Markup Validation Service

The Markup Validation Service is a free online tool that checks the markup validity of the Web document associated with a given URI. You simply enter a URI, and then, the tool checks its correctness (based on the syntax of its document type). Finally, the tool displays an itemized list of errors and warnings (with corresponding line and column numbers) that it finds during the validation process.

Here’s an excerpt from the tool’s validation output:

W3C Markup Validation Service results

V). Keyword Research

When attracting potential customers, it’s important to speak their language. If your site isn’t using the keyword phrases that people are searching for, those people will have a difficult time finding you. Fortunately, a number of free keyword research tools exist.

16. Google AdWords Keyword Tool

Google AdWords Keyword Tool

The AdWords Keyword Tool is one of the most popular free keyword tools available. The tool gives you three options for querying keywords: (1) input a list of keywords, (2) input a URL, which the tool scrapes to identify keywords, or (3) select from a predefined list of categories.

VI). Competitive Keyword Analysis

When conducting keyword research, it’s always interesting to see which keywords your competitors are targeting. How much overlap exists between their keywords and yours? Are they targeting keywords that you haven’t considered? The following free SEO tools can help you answer these types of questions.

20. SpyFu

32. blekko

Update [8/16/2012]: blekko no longer offers free SEO data (it’s now $99/month – insane, I know.) For now, I’m keeping them on the list for nostalgic purposes, in hopes that they eventually come to their senses.

Unlike its bigger and more recognized competitors (e.g., Google and Bing), blekko is significantly more transparent about its index information.
