A question many people ask  is how often should I update my blog?

Many will say as much as possible, the more competitive you niche the more unique content you will need and the more back links you will require to get anywhere with the search engines.

How do you generate Unique Content?

1) Write it yourself – The Best Solution in my Opinion

2)Use Article Writers – Second Best Solutions

3) Re-Write other articles – hmmm maybe

4) Use Content spinners – Don’t do this on you Authority site, maybe it is okay on some feeder sites or Web 2.0 sites but really are you adding any real value to the web?

If you are going to be successful with building back links you are most likely going to use some form of article marketing. There are several flavors of article marketing tools, 1)some send the same article to lots of article directories, 2) some re-write paragraphs and distribute pseudo unique content and 3) some use article spinning to generate unique content that is hardly human readable.

I have tried all, I prefer 1) and 2) myself and have good success at getting good back links.

Research and list provided by Joh Krol.

While conducting the research and search engine checking I did while compiling this very eclectic list of search engines, directories, tools and stuff related, I realized that there are some very competitive trends in a few directions. The most prominent of those seems to be the effort to create the most artificially intelligent NLP, or Natural Language Process, that can be utilized in a search engine. More and more search engines are looking for ways to create search engines that "understand," context, synonyms, meanings, inverted phrases, and more…and well, most of them have been pretty successful at it.

Another trend I noticed is the emphasis on search results produced in "real-time," and I am still not sure I grasp that concept…I mean, aren’t all results delivered in real time? What other kind of time is there? Is there like, unreal time? When a search result pops up after I’ve input a search term, that time sure feels real to me….even more real at 3a.m, after working on an article for the past 9 hours, when my butt has turned numb, and my neck feels like it’s in a vice. But yes, there is a newer method of finding fresher, more immediately published material on a continually updated basis, that search engines are now capable of retrieving. This is especially true with news, blog, and social search engines, all which serve a more immediate need for currency, trends, and "what’s hot."

That being said, I feel I must apologize, because the following list is a bit helter-skelter. It begins with some search engines from a list that was provided to me by the very alternative-search-engine knowledgeable Charles Knight, so that I could include some of the newest and most popular search engines – many of which still seem to be undergoing construction and additions. This is not an alphabetized list, nor even a categorized list, but simply listed in the order that I searched each search engine, directory or whatever.The newest ones are first, some of the middle alternative search engines are in the middle, also thanks to Charles Knight, and then some of the older favorites are last – although you may find this is not entirely a set description either. I hope this list helps anyone looking for stuff they can’t find. Though I had a decent idea of what kind of alternative search engines are out there, I learned some things myself. Have fun looking it all up; some of them really are amazing, and others are just plain cool. I have at least 30 of these saved on my own favorites list, and all of them are worthwhile.

Some Newer Search Engines:

1. One Riot.com is one of the coolest and best new social search engines that searches the web in real time. Users find the freshest and newest social news, blogs and videos on OneRiot, because this real time search engine delivers results as they emerge.

2. Bing.com – in the course of writing this article, Bing went from almost ready to fully available as a search engine. It is what Microsoft is calling a "Decision engine," fully equipped with intuitive features that will deliver more relevant and faster results for your "decision-making." Like many other new search engines and sites, Bing can answer direct questions, such as "What is the capital of Moldova?" differentiate synonyms, and is equipped to compute human language, rather than just text or keywords of a search query.

3. Eeggi.com – an acronym that stands for engineered, encyclopedic, global andgrammatical identities) and claims to be the world’s first "Information engine," according to the website. With eeggi, searches can include synonyms, understand and differentiate between words such as "understand" and "comprehend," and be able to analyze and work around the differences in their meanings. Eeggi also reduces irrelevant search results, providing only specific and detailed queries, as well as search several languages at once, find conclusive and deductive results, respond to users directing search magnitude, and respond to direct questions.

4. Powerset.com – this is the first search engine that developed a human language search function, meaning that it is an attempt to have computers understand the way we talk. Though Powerset for now, only searches wiki articles, it also answers questions directly, and can understand your words, instead of just text – you can express your search in keywords, phrases, or direct questions. Because of Powerset, several other "human language" search engines have been brought into the web search engine world.

5. SurfCanyon.com – this is a powerful new free browser extension that personalizes and optimizes your search on any search engine or directory, including Google, Yahoo, Bing, Craigslist, and more. The software "figures out" what you want, and them makes relevant suggestions, much like Jinni.com does for movies.

6. Imprezzeo.com – an image search engine that allows you to search for other images with examples of images – essentially, it is an image-oriented search engine, that uses images for both reference and results.

Using Boss, anyone can add their ideas, content, and data to Yahoo’s Boss system to create their own unique search engine, by utilizing Yahoo’s entire search index, crawling, page rank and relevancy algorithms.

8. Deep Web Technologies – in addition to being a search engine itself, it also has powered and created an enormous collective of research search engines under the name. Due to its powerful deep web reach, finding information and relevance that most search engines cannot reach, and also working in real time; Deep Web Technologies has created several search engines under its main name:

9. Biznar – re-searches for businesses

12. Scitopia.org – a science, technology and engineering search engine for researchers, focusing on scholarly documents

14. Collecta.com – though they have not launched yet, their site claims to be the web’s most powerful real time search engine, posting photos and posts from sites like Twitter, WordPress, Flickr, and more. What makes them different from other real-time search engines remains to be seen.

15. Taptu.com – a search engine engineered specifically for mobile devices, like the iPhone and the iTouch.

16. Yottalook.com – a free medical imaging search engine that provides decision support at the point of care using proprietary relevance and ranking algorithms byiVirtuoso, and is designed to provide the practicing radiologists the most important and most relevant information they need at the time of patient care.

17. Cooliris.com – an imaging search engine, plug-in, browser add-on, and mobile imaging device that displays search images on a 3-D wall, and has many other very effective features that offer fast and colorful ways to both search and display images, photos and videos.

18. Tazti.com – a speech recognition search tool that can be downloaded to any browser for special needs and hands free searches

19. Viewzi.com – an image search engine that displays search results as a mini-screen that you can flip through as though they are a picture gallery – this means that page rank becomes less of an issue, because of how fast you can flip through results. Viewzi also can be downloaded as a plug-in or add-on.

20. LiveHit.com – a new "social service discovery" that is more than another social network site, it also features the use of many blog search engine tools, showing you what’s hot, and what will become hot, with a special news/events/topic prediction as part of its functions. As with any social networking, an account is required, but it is free.

21. Gazopa.com – a "similar image search service" which allows you to search images using your own photos, drawings, web images and keywords. You can also search for a similar image by extracting a color or shape from another image.Because many images are difficult to explain with text, GazoPa allows you to use partial images and image characteristics to find other images you’re looking for.

22. Kosmix – a general search engine that brings up a magazine-like search result when a search term, phrase or keyword is put in, everything definitions, to relevant links, videos about the topic, articles, photos, blogs, news, and more.Rather than bringing up one result on one topic, it interprets the searched word or phrase and brings up all areas of relevancy, in multiple web forms and media.

23. Worio – according to their site, "Worio is a discovery engine that works alongside keyword search to expose you to stuff you’ve been missing using search alone."Worio also personalizes your search, and "learns" your interests through various methods. When a search term or keywords are input, many other popular results are provided with links to Youtube, Wiki, news sites, and so on, with relevance to the search term. Worio also offers a Library and a Friends page, both which require accounts, for which you can save all tagged pages, and socially network with friends on facebook.

24. SearchMe – According to their "about" page, SearchMe "lets you see what you’re searching for. As you start typing, categories appear that relate to your query. Choose a category, and you’ll see pictures of web pages that answer your search. You can review these pages quickly to find just the information you’re looking for, before you click through." Effectively, SearchMe is a multimedia search engine that allows you to search for search topics in text, music, video, blogs, news, and more, and also displays its search results in the same multi-media presentation, with a combination of both multimedia and non-multimedia search results.

25. Pixsy.com – another search engine that has options of music, video, entertainment and news searches, but seems to require a certain download to be installed, in order to bring up relevant results. I typed in "Explosions in the Sky" under the music search, and it brought up a page with a bunch of explosions in Iraq; at the top of the page it said, "sorry, you have not installed AJAX.." I was looking for a band, not actual explosions, so I haven’t quite figured this engine out yet.

26. TheFindGreen.com – a shopping search engine that focuses on green products, stores, merchandise, and local searches that offer the same.

27. Truevert.com – another green search engine, that also focuses on context instead of just text. For instance, if you type in [hybrid cars], the results will be more about how to convert your car to run on vegetable oil or something, not a bunch of Acura and Honda advertisements.

28. Greenmaven – another green search engine that focuses on green and sustainable websites and topics. They also offer research tools, and an outspoken mission to strengthen the economy through opening the green collective to the web.

29. Videosurf – a free video search engine that searches CNN, Comedy Central, ESPN, Hulu, YouTube, and more for any video, including full t.v. episodes. It’s a step up from Hulu and Fancast, because of its search engine.About.com – an answer directory, sort of a mixture of an encyclopedia, search directory, and trend site.

30. Mytopia – an online gaming community that stretches across both web and mobile platforms, enabling users to have profiles, avatars, chat, messaging, leaderboards, tournaments and competitions in real-time on their iphones, Blackberrys, Razors, Windows mobile, and many other smartphones and mobile operating systems, as well as on Facebook and Open Social.

33. ?ngströ – a people search site for businesses, something kind of resembling a background check, but it pulls from sites like LinkedIn, Twitter and Facebook for information and profiling, for businesses and people needing information on companies and individuals.

34. Popego – a social/recommendation/browser/search that sets you up with your own interests on the web, by searching and filtering out specific videos, articles, news, blogs, and other things that match your personal interests.

35. Mixtt – a new social networking site focused on arranging social grouping and meeting according to city. Unlike most social networking sites that simply aim to enhance time spent online, Mixtt encourages users to meet offline, and mingle with those that would be normally "outside" their normal group of friends and acquaintances, not only regarding who they know, but regarding those that may otherwise be outside their typical subgroup or socially respective common interests. MIXTT is a great source for establishing a new and exciting social life, professional networking, dating, play-time, or any aspect of life that can benefit from an easier and creative way of meeting new and different people. MIXTT encourages people, albeit perhaps passively, to break down barriers of social, socioeconomic, and even racial barriers that may inhibit people from becoming friends, which is truly an admirable quest.

36. Grockit – this is a great combination of a learning and social site, where people learn information by teaching each other in a game-style platform. Grockit users can study for their GMATs, GREs, LSATs, SATs, ACTs, MCATs and more in a creative, fun, and social online environment. A great study and social tool for high school, college, and post-graduate users.

37. Bojam – a site that brings both professional and serious amateur musicians together by allowing them to upload their music, edit and team up with other musicians from around the world. It’s a combination of a both a web-recording studio, and a social platform for musicians to mingle, mix, and play music together with those that match their style and interests. A brilliant engine for providing outlets and searches for other musicians and music to enhance and employ any user’s musical ambitions.

38. Deepdyve – a deep web academic search engine that currently searches for scholarly research on medical and life sciences, and is working to expand their academic topics and broader research sources.

39. iSeek – is what they call a targeted discovery engine, and was voted by The Search Race to be the best Alternative Search Engine last year. iSeek can target and narrow your search results according to topic, source, place, time and date, locations, people, resources, definitions, and also has an additional education search engine. iSeek is definitely a search engine to keep on your favorites list to frequently use, as it is one o the best alternative search engines out there.

Some Middle Search Engines:

The home page starts you off by suggesting looking for your favorite beer, phone, camera, career, and so on, then takes you to a page where you are asked questions that help determine how to narrow the search results – a very innovative way to search for something you love, or even for something you are not quite sure how to find for yourself. I put this one on my favorites list immediately, I thought it was a fabulous search tool.

45. Nozasearch – if any of you have ever had any experience in non-profit organizations, you know how many of them struggle with funding. Nozasearch helps find charitable organizations and donors for non-profit organizations and charities, with features of advanced search and local searches. A fantastic search that is making a proactive contribution to world peace and prosperity.

46. Samepoint – a conversation search engine, which in my opinion, is a brilliant kind of search engine. It varies from regular blog search engines because it searches more than blogs for the conversations that contain your search, and it varies from other search engines because it searches pages that expire and/or are never indexed at all, due to their techie smarts.

47. RSS micro – an RSS feed search engine that offers narrowed results according to date and time the feeds were published in hours, days, weeks, or anytime. It also provides search results in real-time, allowing for the newest and freshest RSS feeds published.

For example, when I searched "outsourcing," it gave me search results from truthout.org, Democratic Underground, and World Net Daily. A great tool for finding little seen or heard news, as well offbeat topics.

49. Megaglobe – an international/global search engine, that not only focuses on global news, economy, politics, legal matters, top stories, and more, but also offers a feature that allows you to ask a question, which is then answered by other users – a pretty cool feature for a search engine.

Users determine the page rank of results by voting on them when the input a search.Sproose also offers recommendation articles, videos and products based upon user searches.

51. Artcyclopedia – an art search directory, that allows you to search by title of work, artist, or the style of art, such as abstract expressionism, art nouveau, post-impressionism, Renaissance, and so on. For each stylistic search, it offers several past and contemporary artists to further research. Thus far, this is one of the best general art search sites I’ve found.

52. Swotti – a product search engine that allows you to search, rate and compare products in over 20 categories like music, entertainment, literature, movies, videos, and more.

53. Sensebot – an information search engine or browser plug-in that summarizes multiple web pages in your search results, for a quicker decision-making process to establish the results that are more relevant.

54. Swamii – the site calls itself "the what’s new engine," but it is basically a "continual" search engine. The way it works starts with a user account, followed by the user entering any information or searches about stuff they want continuous alerts on, and Swamii then alerts the user on an ongoing basis about the input search. Actually, this is a great tool for someone that writes about stuff on an ongoing basis, or is doing research over a period of time, or even someone with a hobby or pursuit that wants to keep up with it.

55. Trovit – a classifieds search engine that serves 11 different countries, where users can find apartments, jobs, cars and more.

62. Factbites – in addition to delivering search results for search queries, this search engine also lists the results in simple sentences, so that a user may more clearly understand what the web page is about, and how relevant it is to the search

63. Faroo – I feel slightly biased about this site, simply because it is one of the most idealistic out there, and I have not yet come across another one like it. This is a peer-to-peer website, where users passively decide page-rank algorithms, determined by which pages are looked at for a particular search. Not only that, but Faroo has a democratic, and almost even a socialist approach to their revenue – they share advertising revenue with users that have accounts. This is one of the best ways I’ve seen a company try to defeat the beast of monopoly.

64. BlogDimension – this blog search engine doesn’t just search blogs in its index, but also podcasts, online videos, images and microblogs, such as on Twitter.

68. Hakia – hakia narrows down search results to the most credible web pages and web sites in your search results, in order to save time wasted on results that may appear relevant, or have related content regarding a particular search, but that stem from less-than-credible sites. Hakia strives to eliminate those through ontological and semantic NLP technology.

69. GenieKnows – this unique little search engine is sort of a cross between a local search and a travel search. It searches all over Canada and the U.S., allowing users to find things like "where to find antiques in Montreal," or "the best plastic surgeons in NYC," or even small town information about events, places and people.

70. iSearch – a free people search that simply allows users to search for people using their first and last names and location, their email address, phone number or even their screen name.

I disabled several plugins and Ithemes and WP2.8 seem to work now.

There is definitely some form incompatibility between Ithemes,WP2.8 and a few plugins I had installed.

As you can see from my site Ithemes and wordpress 2.8 do not work well together.

I just upgraded to WP2.8 and Ithemes does not seem to work too well.

The problem seems to be something to with widgets, I am not able to add widgets.

Other themes seem to work okay but not Ithemes, which is a shame as I like Ithemes alot.

Recession Help Expo

I really like this tool for capturing leads as your visitors exit you site.
