    Agreed, a summary of which one is best, or even a review of the best 3 would be much more helpful. I’ve tried quite a few over the years, including many on this list, and they often have problems which outweigh their usefulness.

    @Laura, I don’t want to be picky, but the post title made me wonder – “How can you have an add-on that’s free of SEO” – I think you meant “25 Free SEO Add-ons”

    Then again, maybe not a bad way to grab traffic – create a title that makes people wonder what’s inside – any marketers tried that before?

    These are really nice SEO add-ons. Nice list you got here, and thanks for sharing these, i’ll definitely use it to help on my campaign. Good Luck to your further posts.

    Freelance FactFile,

    When I installed the SEO Doctor I was prompted to restart Firefox. After I restarted, the SEO Doctor icon, which is a green flag, displayed in the far right of the URL field. When you hover your mouse over the green flag information about the page you are viewing displays.

    I hope this helped. :)

    В интернете громадное число разнообразной информации, и если бы не поисковик, то, наверняка, вы толком никогда не в силах бы найти то, что вам необходимо. Главная задача раскручивания проекта состоит в фиксации в google, яндекс, чтобы люди, вводя ключевые фразы, соответствующие описанию Вашего сайта в строке запроса, могли легко его отыскать. Но не все так хорошо, ведь стопудово на Вашу тему уже много ресурсов в выдаче. Если вы попросту зарегистрировали свой ресурс, не проделав с ним важных “операций” заранее, то знайте, что Вы выполнили обычную формальность и о каком-либо трафике посетителей с поисковиков можете и не вспоминать. Люди должны посещать Ваш проект, если ресурс будет правильно настроен. Оптимизация-так обозначается процесс подстройки под ключевые слова. Бесспорно, среди русского интернета самым популярным поисковиком остается яндекс. Яндекс имеет очень хороший шустрый поисковый робот. Ваш сайт очень шустро попадет в поиск, если вы зарегистрируете его в yandex. Но лишь только сайт будет просканирован целиком, не факт, что он останется в результатах выдачи навсегда, потому что робот может принять ее как неуникальную. Чтоб яндекс посчитал Ваш проект белым, необходимо обязательно наполнять его уникальным материалом. http://oldmedik.ru/

    I usually do not leave a response, but after looking at a bunch
    of remarks on 25 Free SEO Add-ons for Mozilla Firefox | FreelanceFolder.
    I actually do have some questions for you if it’s okay. Is it only me or do some of these comments appear like they are coming from brain dead individuals? :-P And, if you are posting on additional places, I’d like to follow you.
    Could you make a list of all of all your shared pages like your linkedin profile, Facebook page or twitter feed?

  14. says

    Pretty good list of SEO tools for Firefox, though I stopped using the browser. Today I use Chrome, wich have a few good extensions aswel, like SEOmoz toolbar. How about making a list like this, but for Google Chrome?

  15. says

    Really cool ideas for helping a company to improve SEO.
    I think that it’s hard to find the right addons due to that its a bit difficult to just use 1-2, and 4-5 will be complicated! I only use seomoz at this moment, works fine for me.

    Beslutter at låne penge fra en ven kan ikke virke som en big deal, men låne penge gennem et kortfristet lån er en alvorlig forpligtelse. En ven eller et familiemedlem, kan forstå, hvis du har brug for et par ekstra dage til at få det fulde beløb sammen, men et lån udbyder ønsker alle deres penge betalt på den dato, du aftalt.

    hey there and thank you for your information – I have definitely picked up something new from right here.

    I did however expertise some technical points using this site, since I experienced to reload the website a lot of times
    previous to I could get it to load correctly.

    I had been wondering if your hosting is OK?
    Not that I am complaining, but slow loading instances times will very frequently affect
    your placement in google and could damage your high-quality score if advertising
    and marketing with Adwords. Anyway I’m adding this RSS to my email and could look out for much more of your respective interesting content. Ensure that you update this again soon.

    Points are there for you to elicit the aggressive drive, and with this loyalty (for the
    Software program, not the chums). A sense of public achievement can be
    stimulated by the use of chief boards and automatic comparisons with the customers’ buddies.

    I’ve been browsing on-line more than three hours nowadays, yet I by no means found any fascinating article like
    yours. It’s beautiful valuhe enough for me.
    Personally, if all web owners and bloggerfs made good content material as
    you probably did, the net will likely be a lot more useful
    than ever before.

    Its such as you learn my mind! You appear to understand so much approximately
    this, such as you wrote the e book in it or something.
    I think that you just can do with some percent to power the message home a bit, but other than that, that is magnificent blog.
    An excellent read. I will definitely be back.
