Скрипта в действие:
http://data-recovery.freehostia.com/rss.pl
http://data-recovery.freehostia.com/data_recovery_rss.pl
http://data-recovery.freehostia.com/electronics_rss.pl
http://data-recovery.freehostia.com/physics_rss.pl

Идеята на този скрипт е да се направи съдържанието на блога динамично (Blogger поддържа RSS feeds и от време на време проверява за промени и актуализира страниците).

Текста от "my $data = <<END_OF_DATA;" до "END_OF_DATA" е списък с връзки в много прост формат („адрес текст“ следващ ред „адрес текст“ и т.н. (има един интервал между адреса и текста)). С променливата $how_many_random_news се определя колко случайни връзки да се генерират.

Написал съм и други скриптове (напр. автоматично добавяне на нови връзки в списъка), но ще ги публикувам друг път (когато ги приведа в по-приличен вид).

Blogger кешира данните, получени от RSS. Ако желаете да обновите страниците си веднага (вместо да чакате на Blogger да му мине случайния интервал от време, след който се обновява кеша), редактирайте адреса на RSS-а като добавите „?някакъв_случаен_низ“:

georgimateev каза:
Т'ва горното огромното защо не го научите да си взима динамично линковете и заглавията? ;)

Може да се направи при всяко стартиране да се проверява дали едно случайно число е равно на някаква константа и ако се наблюдава равенство да тегли RSS от други сайтове и да ги добавя във файл (напр. средно на всеки 10 посещения), но ако е на безплатен хостинг собственикът няма да е много доволен (обикновено го пише в условията за ползване: скрипта, стартиран на сървъра да не взима съдържание от други сайтове, което правят например уеб прокситата от рода на php proxy). Ако хостингът поддържа crond ще отпадне проверката на случайното число дали е равно на някаква константа.

Тази забрана се заобикаля като обновяването на скрипта става на друг компютър и се качва чрез ръчно стартиране на един скрипт, който си събира каквото трябва от където трябва.

Извинете за въпроса, но тези скрипт с рандом постовете на RSS, къде точно да го събмитна ? Знам, че Гугъл харесва чести промени по съдържанието на даден сайт, на това в случая е RSS фийд, и не зацепвам какво Гугъл може да направи с нея... ?

един може би странен въпрос от мен: събмитвате ли фийдс в изброените директории от сайтове с български кънтент? Доколкото виждам директориите са нон бг и не знам има ли смисъл да събмитвам rss от един мой кирилишки блог :)
ако не къде събмитвате такива?
 

Blinky

Аз лично мисля че няма смисъл, бате. Все пак като не го разбират езика няма да те четат даже и да излезеш в някоя директория за дадена категоря. Но все пак са много, може да се поразровиш дали някои имат и други езици. Малко ме съмнява за нашият, но все пак проба-грешка.:)
 

Blinky

Owner
Добре си дошъл бате. Кофти е, но нямаме още добре затвърдени блог директории на български. Пропуск, но факт. И това ще се развие скоро.:) Ето идеят за някой, който иска да оперира в тази ниша. Може да избира между няколко модела - блог директория, Rss feed агрегатор, Бг Диг.....:)

Навсякаде ли бухате rss-feedо-вете,да докарват всякакв трафик? Или си подбирате директориите да идва само таргетиран трафик? Щото не в всяка директория има примерно за хазарт както е в моя случеи, и се чудя наред ли да дера, или да подбирам.
 

Blinky

Owner
Еми то е хубаво да идва повече трафик, от къде ли не. А и да в не всяка директория има категория отговаряща на тематика на даден блог, но винаги може да се намери сходна или близка до нея. Примерно в твоят случай е Забавления -> Игри....

Аз лично наред ги опрашвам:) Все си намирам категория. Даже малко или много блога ти е инфо ресурс, което може да попадне и в категоря - Education.:) Зависи колко си алчен за трафик от този вид стратегия.:)

Успехи...
